2. Introduction  
You’ll find that the user-friendly design of this Phone Line Manager 16 x 4 (Integrated Phone Solutions)  
system and the clear, step-by-step instructions in this manual will make it a pleasure to set up the system’s  
features so that they best serve your office.  
This guide describes enhancements made to the Phone Line Manager 16 x 4 telephone system as of the  
Version 140 release of the software.  
®
®
If you have a personal computer with Microsoft Windows installed, you will want to use our configuration  
program (see Section 18.2).  
Plenty of flexible-phone features are built into the system, and you can pick and choose the ones that suit  
your home or office. As a first step, browse through this manual to get acquainted with the various features  
available.  
When your new unit arrives, all of the features are already programmed with default settings. In some  
cases, these settings will be fine just as they are. With others, you will want to change the settings. The  
instructions in this manual lead you through the simple step-by-step process of setting each feature as  
desired.  
In Section 3.4 you’ll find a list of pre-programmed default settings. Refer to this list as you set up your  
system. It lets you see at a glance which features you will need to set. If you need to, you can easily return  
the whole system to all of its default settings at any time.

3. Preparing to Program  
Before entering the system program features, take some time to look over the different options for setting  
up an extension as the System Manager.  
3.1 Designate an Extension for System Manager  
All programming functions in this manual must be performed from the programming extension. Initial  
programming of the Phone Line Manager 16 x 4 system must be done from extension #15. This extension  
should be assigned to the person who will program the system and serve as System Manager for the office.  
The default programming extension is preset as extension #15. You have the option of changing it to  
extension #00. This would be handy, for example, if the Operator is at extension #00 and you want the  
Operator to also serve as the System Manager.  
To change the programming extension to #00:  
1. At the System Manager’s extension, lift the handset and enter 7832. Pause for confirmation tone.  
Hang up or continue programming.  
To set the programming extension to #15:  
1. At the System Manager’s extension, lift the handset and enter 7833. Pause for confirmation tone.  
Hang up or continue programming.  
3.2 Choosing the Programming Mode—Automatic or Password  
With the default settings, the System Manager is required to enter a 6-digit password from their extension  
to place the Phone Line Manager 16 x 4 in the Programming Mode. The password is entered by dialing the  
code 761, followed by a 6-digit password. (The default value of password is 123456.) In this mode, the  
System Manager can enter any programming codes. The password requirement prohibits unauthorized  
persons from changing the programming. It can also reduce the likelihood of accidental changes in the  
configuration.  
If you want to, you can remove the password entry requirement. This is useful for installations where  
security is not an issue. It is, however, strongly suggested that the password be used so that an accidental  
dialing sequence does not alter the system programming. For instance, if the System Manager forgets to  
dial 9 (or 0) to make an outgoing call and then dials a number sequence beginning with a 7, they could  
be accidentally entering a programming command.  
To allow programming without the entry of a password:  
1. At the System Manager’s extension, lift the handset and enter 7849. Pause for confirmation tone.  
To require the entry of a password to enter Programming Mode:  
At the System Manager’s extension, lift the handset and enter 7848. Pause for confirmation tone.

3.3 Programming Tips  
• All programming described in this manual must be performed in the programming mode (see Section  
3.5) and performed from the programming extension (see Section 3.1).  
• We recommend that the programming extension be assigned to the person who will act as System  
Manager for the office.  
• If a desired feature is preset in the “enabled” mode, no programming is needed unless you want to  
disable the feature.  
• If the final step in an operation reads “hang up,” you must do so for the programming to register.  
• If the final step reads “hang up or continue with programming” you can stay in the programming mode  
and proceed directly to programming another feature.  
• You probably will want to program a number of features in one sitting. However, please be aware that you  
will be automatically “bumped” from the programming mode if you hang up for more than two seconds.

When You Reset the System to Default Values:  
All features are reset to the factory-default settings. These will be the same as the values on your new system.  
In addition:  
• All call forwarding is cleared.  
• All alarms are cleared.  
• Call history memory is erased.  
• Extensions assigned to call barring (toll restriction) tables are cleared, but contents of the call barring  
tables are not affected.  
• Speed dial numbers are not affected.  
• Your voice announcement message is not affected.  
3.5 Entering the Programming-Mode Password  
If you are required to enter a password to access the programming mode, the following password command  
will be used.  
1. At the System Manager’s extension, lift the handset and enter 761.  
2. Enter the 6-digit password (Default = 123456). Pause for confirmation tone.  
3.6 Changing the Programming-Mode Password  
If you are requiring the System Manager to enter a password to access the programming mode, you may  
change the password if, for security reasons, you do not want unauthorized people changing system settings.  
The default value of the password is 123456. To change the value:  
1. At the System Manager’s extension, lift the handset and enter 761, followed by the current 6-digit  
password (Default = 123456). Pause for confirmation tone.  
2. Enter 762.  
3. Enter the new 6-digit password. Then enter the new 6-digit password again.  
4. Pause for confirmation tone. Hang up or continue programming.  
3.7 Resetting the System to Default Values  
This command will reset all features on the system to default values. See the default settings list in Section  
3.4. This list shows what the settings will be for all features after you perform this command.  
Resetting the system to default values allows you to start from a “clean slate” when reprogramming the  
system after values have been changed.  
To reset the system to default values:  
1. In the programming mode, enter 7873. Pause for the confirmation tone.  
2. Hang up or continue programming.

PHONE LINE MANAGER 16 X 4  
4. Configuring the Extensions  
4.1 Choices When Programming the Extensions  
Each extension must be individually defined in the way that best suits your needs. The options to be decided  
upon are described below. These choices are programmed for the extension using the commands given on  
the following pages.  
1. What type of phone will be connected to the extension?  
An extension can be connected to an ordinary phone, a key phone, a fax machine, or a door phone. (A  
door phone is an intercom at the outside door of your office, which visitors use to reach an operator. See  
Section 4.3 for additional information.) The system needs to know the phone type to communicate properly.  
2. Which special features do you want to allow the extension?  
• Call Hold/Transfer: Allows the extension to put an outside call on hold or transfer an outside call to  
other extensions. This capability may not be withheld from key phones.  
• Call Hold Retrieval: Allows retrieving a call placed on hold at another extension. This capability may  
not be withheld from key phones.  
• Rollover Extension: Typically a voice mail or answering machine. (See Chapter 13).  
• Exclusive Answering Machine Privilege: Allows this extension to have a dedicated answering machine  
on the next numerical extension. (See Chapter 13).  
• Call Break-in: Allows “breaking in” or interrupting another extension’s phone call.  
• Emergency Alarm: Allows an extension to generate an emergency alarm signal to other extensions.  
• Paging Groups: Allows a key phone or a door phone at the extension to be part of a paging group.  
• Caller ID Display: Allows an AVT-16 series key phone to display the incoming Caller ID information.  
• Automatic Outside Line Seize: Allows an extension to automatically connect to an outside line when  
they lift their handset without dialing 9 (or 0). If the person at that extension wants to make an intercom  
call or use other Phone Line Manager 16 x 4 functions, they can simply switchhook before dialing any  
digits to drop the outside line and connect to the Phone Line Manager 16 x 4 dial tone.  
3. Do you want to give new numbers to the extensions?  
Each extension is automatically given a number by the system. This is the number on the jack at the unit  
into which the extension line is plugged. The numbers are 00 to 15 for the Phone Line Manager 16 x 4.  
However, it may be more logical to give your lines different numbers (for example, ones that correspond  
to office or room numbers).  
Please note that even after you assign new numbers, the extension numbers on the jacks (00 to 15)  
still need to be used for all system programming where a 2-digit extension number is required. The  
new extension numbers you assign are used when:  
• making intercom calls,  
• transferring outside calls to another extension,  
• entering an extension number in the Auto-Attendant (or DISA) mode,  
14  
 
PHONE LINE MANAGER 16 X 4  
• forwarding calls to another extension,  
• and turning on or off the message lamp of another extension.  
If Hunt Groups are used (see Chapter 10), the extension numbers 122, 133, 144, and 155 are reserved.  
You may not assign an extension to use one of these numbers.  
4.2 Programming the Extensions  
The configuration settings for each extension must be programmed separately. The programming  
procedure is simple if you take it step-by-step. First, decide on the codes you want to enter for each  
extension. Write down the code for each of your choices. Then program one extension at a time. You  
must complete all steps for each extension before starting on the next one. The “*” mark indicates the  
default value of each setting.  
1. In the programming mode, enter 75.  
2. Enter the 2-digit extension number (00 to 15).  
3. Enter the code for the phone type and features:

4.3 Door-Phone-Operation Details  
Any extension, with the exception of Extension #00 and the System Manager’s extension, may be configured  
to be a door phone. The Door Phone may be placed at any location requiring a hands-free intercom station.  
In addition, any ordinary phone can be used as a door phone. When a person at the door phone goes  
offhook (or presses the button on the Door Phone), an alert ring is heard on the first four available  
extensions in the Standard Incoming List. This is similar to an incoming call where the first four available  
extensions in the Standard Incoming List are rung.  
Any of the ringing phones may go offhook within the next 12 seconds to make a connection with the  
Door-Phone extension. More than one phone may connect to the Door-Phone extension.  
Also, any extension can make an intercom call to a Door Phone and they will be immediately connected  
with the Door Phone operating in a hands-free mode. An intercom call to an ordinary phone connected to  
an extension programmed to be a door phone will ring normally.  
17  
 
PHONE LINE MANAGER 16 X 4  
4.4 Call Forwarding/Call Follow Me  
Occasionally you may be required to work in an associate’s office and will want to have your phone  
forwarded to the other person’s office. This feature is called “Call Forwarding” when you enter the  
forwarding command from your extension. The feature is called “Call Follow Me” when you issue the  
command from the extension to which you want the calls forwarded.  
The Call Follow Me feature allows you to forward your calls to the new office without having to go back to  
your office. In some installations, it may not be desirable to allow any user the ability to have calls transferred  
to it by invoking the Call Follow Me command. For instance, a person at an extension in a hotel could  
accidentally have calls meant for the Operator sent to him.  
To disable the Call Follow Me function:  
1. In the programming mode, lift the handset and enter 7822. Pause for the confirmation tone. Hang up  
or continue programming.  
To enable the Call Follow Me function:  
1. In the programming mode, lift the handset and enter 7823. Pause for the confirmation tone. Hang up  
or continue programming.  
A special exception to Call Forwarding is made to facilitate operation between a manager and his  
secretary. If the manager has his calls forwarded to the secretary’s extension, the secretary (but no one else)  
is able to make an intercom call to the manager’s extension or transfer an outside call to the manager. Any  
other extension attempting such a call would have the call forwarded to the secretary’s extension.  
4.5 Require Star Key Before User Programming  
All of the user-programming commands begin with a 4 or 5. In some installations, you may want to require  
that the user enter a * from the keypad of the phone before entering one of these commands. This will  
prevent unintentional programming if a person dials a phone number beginning with a 4 or a 5 but forgets  
to dial 9 (or 0) to connect to an outside line. For instance, an extension could be accidentally placed in the  
Do Not Disturb mode, or the Day/Night setting could be changed. When this new parameter is set, dialing  
a 4 or a 5 without first dialing a * will give an error tone.  
Note that telephone sets with rotary dials cannot dial a *. Thus, this setting should not be enabled if there  
are pulse-dialing telephones connected to the system.  
To require a * to be entered before a 4 or a 5:  
1. At the System Manager’s extension, lift the handset and enter 7838. Pause for confirmation tone.  
To not require a * digit to be entered before a 4 or a 5:  
1. At the System Manager’s extension, lift the handset and enter 7839. Pause for confirmation tone.

PHONE LINE MANAGER 16 X 4  
5. Central Office Lines: Incoming Calls  
5.1 Introduction  
This chapter, which describes how incoming calls are handled in the Phone Line Manager 16 x 4, begins  
the discussion of how to configure the outside lines. The next chapters describe the main configuration  
commands, followed by a discussion of Auto-Attendant or DISA (Direct Inward Station Access), then a  
description of Outgoing Call Groups, and finally a discussion of DOSA (Direct Outward Station Access).  
Later in this manual is a discussion of advanced topics concerning the setup of outside lines.  
5.2 Choices in Handling Incoming Calls  
Your flexible system offers many options for handling incoming calls. The choices are:  
5.2.1 STANDARD INCOMING LINE OR PRIVATE INCOMING LINE  
The first choice to be made for each outside line is whether you want the Phone Line Manager 16 x 4  
to handle incoming calls in a “standard” fashion or whether you want a particular line to be a “private  
incoming line” and ring at an extension other than the Operator. Outside line #1 is always a Standard  
Incoming Line while each of the others may be optionally configured to be Private Incoming Lines.  
5.2.2 AUTO-ATTENDANT OR DIRECT INWARD STATION ACCESS (DISA)  
Next, you can decide if you want the Phone Line Manager 16 x 4 to automatically connect incoming calls to  
a recorded voice announcement which leads the caller through options for reaching individual extensions.  
In this mode, the Phone Line Manager 16 x 4 can also be programmed to listen for an incoming fax tone  
and route the call directly to the extension where the fax machine is located. This type of operation is called  
Auto-Attendant or DISA (Direct Inward Station Access).  
The alternative to DISA is that the Phone Line Manager 16 x 4 will sense an incoming call and cause one  
or more extensions to ring. In this case, a connection to the outside line will not be made until one of the  
ringing extensions goes offhook.  
5.2.3 DAY-TIME AND NIGHT-TIME HANDLING OF INCOMING CALLS  
The Phone Line Manager 16 x 4 can operate in the Day Mode or the Night Mode and each outside line can  
be set to operate differently when in the two modes. For instance, an outside line can operate as a Standard  
Incoming Line during the day and as a Private Incoming Line during the night. You can have an incoming  
call ring at one group of extensions during the day and a different group of extensions at night. You can also  
choose to have the Auto-Attendant (or DISA) mode operate during the day, night, or both.  
5.2.4 INCOMING-CALL ALERT TONE TO THE PAGING SYSTEM  
Calls can be setup to ring over a paging system in addition to ringing at individual extensions. Anyone can  
answer the call from any extension by dialing 3. This is recommended for businesses where employees are  
not seated at desks with phones, or where there is no receptionist/operator.  
5.2.5 INCOMING CALLS TO AN AUTO-ATTENDANT SYSTEM  
If you are using an Auto-Attendant/Voice Mail system, you can choose to have incoming calls ring at the  
Auto-Attendant or at an operator’s extension. Simply enter the Standard Incoming Line list to reflect the  
extensions to which you would like to direct the incoming calls.  
19  
 
PHONE LINE MANAGER 16 X 4  
5.2.6 DEFINING THE STANDARD INCOMING LINE  
In most installations, all outside lines would be configured as a Standard Incoming Line. You will first define  
a list of extensions which will ring when an incoming call is detected. You might also choose to define a  
second list of extensions which will ring when an incoming call is detected in the Night Mode.  
The operation of an outside line configured to be a Standard Incoming Line is as follows. When an  
incoming call is detected, the Phone Line Manager 16 x 4 checks the extensions starting at the top of the  
appropriate (day or night) list to find the first available extension. This extension will start ringing. Zero  
to nine rings later (see Section 19.15), the Phone Line Manager 16 x 4 will find the next three available  
extensions in the list and start ringing them. After 5 to 60 seconds have passed (see Section 19.11), the  
Phone Line Manager 16 x 4 will ring an available Rollover Extension (usually a Voice Mail unit or answering  
machine).  
Additionally, all key phones with the “RP’” (Ring Position) indicator set will also ring when incoming calls  
are detected on outside lines configured as Standard Incoming Lines.  
5.2.7 THE OPERATOR EXTENSION  
One extension is designated to be the Operator. The Operator extension is used by the Phone Line  
Manager 16 x 4 in the following ways:  
Any extension may dial 0 (or 9) to place an intercom call to the Operator or to transfer an outside call to  
the Operator.  
Only the Day mode Operator may issue a 56 command or a 57 command to manually switch the Phone  
Line Manager 16 x 4 into the Night mode or the Day mode.  
An incoming call to an extension on a Private Incoming Line that goes unanswered will ring the  
Operator’s extension if the Operator is not busy.  
A call left on hold too long will ring at the extension which placed it on hold. If that extension does not  
answer or is busy, the call will ring at the Operator’s extension if it is not busy.  
A call parked at an extension will ring the Operator (or a Rollover Extension, as programmed by the  
System Manager) if the extension at which the call is parked does not become available or if the extension  
becomes available but does not answer when the phone rings.  
A blind transfer of an outside call to an extension which does not answer will ring the Operator (or a  
Rollover Extension, as programmed by the System Manager) if the extension to which the call is being  
transferred does not answer.  
If an incoming caller to an outside line operating in the Auto-Attendant (or DISA) mode specifies an  
extension which does not answer, the call will transfer to the Operator.  
If no input (either DTMF digits or a fax Calling Tone) is detected during a DISA call, the call will ring  
at either the Operator’s or the fax’s extension, as programmed by the System Manager.  
5.2.8 THE STANDARD INCOMING LIST—WHICH EXTENSION IS THE OPERATOR  
The first (non-Rollover) extension in the Standard Incoming List is defined to be the Operator. This means  
that if your Standard Incoming Line List directs incoming calls to an Auto-Attendant/Voice Mail, the  
Operator will be defined as the next extension in the list after the Voice Mail extensions (because your Voice  
Mail extensions would be defined as Rollover Extensions). Since there is a separate list for Day and Night  
operation, a different Operator extension can be defined for each mode.

5.2.9 ENTERING THE STANDARD INCOMING LIST  
1. In the programming mode, enter 730 for the Day Mode list or enter 790 for the Night-Mode list.  
2. Enter the two-digit extension numbers (00 to 15) assigned to the Standard Incoming List.  
Enter all of the extension numbers in succession. You can assign up to 16 extensions. Be sure to enter  
the extensions in the order you want them to be searched.  
3. Hang up. Hanging up is necessary for the assignments to register.  
Keep a record of your Standard Incoming List Assignments. Write the 2-digit extension numbers in the  
following table.

5.2.10 PRIVATE INCOMING LINES  
You may want to configure one or more of the outside lines to operate as a Private Incoming Line. This  
would allow an incoming call to ring at an extension other than the Operator. Outside lines 2, 3, and 4 may  
be defined as Private Incoming Lines. As such, you can define the list of extensions which the Phone Line  
Manager 16 x 4 will search when an incoming call is detected on that line. Only one extension will ring. This  
is different from outside lines defined as Standard Incoming Lines where more than one extension can ring  
at the same time.

2. Enter two-digit extension numbers (00 to 15) assigned to the Private Incoming List.  
Enter all of the extension numbers in succession. You can assign up to 16 extensions. Be sure to enter the  
extensions in the order you want them to be searched.  
3. Hang up. Hanging up is necessary for the assignments to register.  
For non-DISA calls to a Private Incoming Line, the Phone Line Manager 16 x 4 will ring the first available  
extension in the appropriate (day or night) list. If the extension does not answer within the “Rollover After  
Call to Extension” time, the call will start ringing at the next available extension in the Private Incoming List,  
not including the extension that is currently ringing. This process will repeat until the incoming caller hangs  
up and the ringer signal is no longer present.  
One typical configuration would be to put the Operator as the second extension in a Private Incoming  
List. If the Operator does not answer, the call will start ringing at an available Rollover Extension. Another  
typical configuration would be to put an answering machine or voice-mail-unit extensions in the list. Since  
the Phone Line Manager 16 x 4 allows both Day Mode and Night-Mode lists, you will want to make sure that  
an answering machine or voice mail is the first or second extension in the night list so that calls received  
after hours will never go unanswered.  
In any case, it is best that the Private Incoming List be filled with enough entries so that the call always has  
a place to ring. If there is no available extension in the Private Incoming List, the call will park at the first  
extension in the list and give a beep signal every few seconds to inform the caller that a call is waiting.  
Keep a record of the Private Incoming Line Lists. Enter the extension numbers for each outside line  
configured as a Private Incoming Line:

5.2.12 SETTING INCOMING CALLS TO RING OVER PAGING SYSTEM  
This option allows incoming calls to ring over a paging system in addition to the operator. Anyone can pick  
up an extension and press “3” to answer the call. This is useful in businesses where employees are not seated  
at desks with phones, or where there is no dedicated receptionist/operator. Outside lines must have the  
Auto-Attendant (or DISA) mode disabled for this feature to work. Also, your paging system must be plugged  
into paging system jack of the unit.  
To enable a ringback tone over the paging system:  
1. In the programming mode, lift the handset, enter 7810. Pause for confirmation tone.  
To disable a ringback tone over the paging system:  
1. In the programming mode, lift the handset, enter 7811. Pause for confirmation tone.

Each CO line should be configured so that it best suits your needs. The options that must be decided upon  
are described below.  
1. Are you using this CO line?  
If you do not use all of the CO line ports of the system, then the vacant ports need to be programmed as  
“Disable.” This will make sure the Phone Line Manager 16 x 4 does not allow any extension to connect to  
this line.  
2. How should an incoming call be answered?  
You may select DISA (Direct Inward Station Access) for answering incoming calls. This feature is also called  
Auto-Attendant mode. In this mode, the Phone Line Manager 16 x 4 will answer (Day or Night) and prompt  
the incoming caller to enter the digits or code of the desired extension or department that they wish to  
speak with. Read more about DISA before selecting this feature so as to better understand its function.  
If you choose to use the line so that the call must be answered by an extension before the outside line is  
seized, then you will need to enter the code for “No DISA.”  
3. Does your CO line accept tone (DTMF) or pulse (rotary) dialing?  
Some older Central Office switches can interpret only pulse or rotary dialing. Most newer Central Office  
lines can accept tone or DTMF (Dual-Tone Multi-Frequency) dialing. The Phone Line Manager 16 x 4 will  
need to know how it should dial digits when it is dialing a speed-dial number or redialing the last number  
dialed. See Section 12.1 for a complete discussion of the dialing mode.  
4. Do you want to be able to send a “switchhook” to the CO line?  
Some Central Office features, such as Call Waiting, are enabled by sending a “Switchhook” or “Flash” to the  
Central Office. Some Central Office switches will reset the CO line and give a new dial tone in response to a  
Flash signal. If a new dial tone is given, the caller could bypass the Call Barring (Toll Restriction) protection  
as the system would not know that a new dial tone was received. If this is a consideration, you may wish to  
disable the sending of the “switchhook” signal to the CO line.  
The system Flash signal is set at a default value of 480 ms. This default value should work with most  
signaling requirements. If not, the timing duration of this signal may be changed to work with the  
requirements suggested by the Central Office for the features that they may provide in your area (see  
Section 19.5).  
5. How do you want the incoming lines to ring?  
All incoming CO lines will ring into the system. This step is used to select the manner in which you wish for  
them to ring according to the use of the desired CO line. For each line, you can choose to configure it to  
handle incoming calls according the Standard Incoming Line configuration, or you can configure it to be  
a Private Incoming Line.  
6. Do you want the unit to automatically detect incoming faxes?  
Each CO line can have an assigned fax extension to allow the system to automatically direct an incoming fax  
(when the fax tone is detected) to an extension where a fax machine is connected. The CO line must be in  
the DISA mode to allow automatic fax detection.

PHONE LINE MANAGER 16 X 4  
7. Do you want to dial 9 or 0 to access an outside line ?  
You can choose either 9 or 0 as the code for the user to dial when requesting an outside line.  
6.2 Dialing “9” to Access Outside Lines  
The system is preset so that users dial 9 to access an outside line and 0 to make an intercom call to the  
Operator. You may want to change the 9 to a 0 if this is the standard in your area.  
To access an outside line by dialing 0:  
1. In the programming mode, lift the handset and enter 7801. Pause for confirmation tone. Hang up  
or continue programming.  
To access an outside line by dialing 9:  
1. In the programming mode, lift the handset, enter 7800. Pause for confirmation tone. Hang up  
or continue programming.  
NOTE  
If you configure the system so that “0” accesses an outside line, “9” will then directly dial  
the operator. If “9” is the number for outside line access, then “0” will dial the operator.  
6.3 Programming Outside Lines  
Each outside line must be programmed separately. The programming procedure is simple if you take it step-  
by-step. First, decide on the codes you want to enter for each line. Write the code for each of your choices in  
the table provided on the next page. Then program one line at a time. The default settings are marked with  
an asterisk (*).  
1. In the programming mode, lift the handset and dial 739.  
2. Enter the line number (1 to 4).  
3. Enter the code for enabling the CO line and for Auto-Attendant (or DISA) operation.

7. Auto-Attendant (DISA)  
7.1 About DISA and Direct Caller Access to Extensions  
Enabling the Auto-Attendant or DISA (Direct Inward Station Access) feature for outside lines allows  
incoming callers to connect themselves directly to an extension. The optional Voice Announcement module  
can be enabled to lead the caller through options for reaching individual extensions. The Phone Line  
Manager 16 x 4 can also be programmed to listen for an incoming fax tone and route the call directly to the  
extension where the fax machine is located.  
Setting DISA as enabled or disabled is done as part of setting the command sequence for “Programming  
Outside Lines” (see Section 6.3). This is done separately for each line. You have the option of enabling DISA  
at all times, during regular business hours (Day Mode), or after regular business hours (Night Mode).  
In the Phone Line Manager 16 x 4 there is only one Voice Announcement module and one circuit to  
collect the digits coming from the outside caller when the call is answered in the DISA mode. If two  
incoming calls are received at the same time and both outside lines operate in the DISA mode, the second  
incoming call will continue to ring and will not be answered until after the caller on the first line has made  
their DISA selection.  
After the Phone Line Manager 16 x 4 answers the incoming call and the optional voice announcement  
module is playing the recorded message, the incoming caller can dial:  
0
To call the Operator  
1xx  
To ring extension 1xx where xx is the extension number (00 to 99) assigned using the  
Configure Extension command  
2, 3, 4, or 5 To ring the first available extension in Hunt Group 2, 3, 4, or 5  
6 or 7To invoke the DISA feature  
7.2 Recording a Voice Announcement  
This command allows you to record an announcement to greet callers. The recording can be made only  
from Extension #15. (See Section 3.1 if you need to change the programming extension to 15).  
Time the length of your spoken announcement before recording it. If you want to record a very short  
announcement, you can enter 0 at the end of your message, which will cause the Phone Line Manager 16 x 4  
to ring the Operator.  
1. In the programming mode, enter 728. Pause for the confirmation tone.  
2. Record your announcement by speaking into the handset. When you have finished speaking, keep the  
phone off the hook until you hear a confirmation tone. This marks the end of the 20 seconds available.  
(If the tone cuts you off, re-enter 728 and record a shorter announcement.)  
3. Hang up or continue with programming.  
27  
 
PHONE LINE MANAGER 16 X 4  
Sample Announcement  
“Hello, you have reached XYZ Corporation. To send a fax, press the start button on your fax machine at any  
time. If you are calling from a touchtone phone, you may enter the extension number of your party at any  
time. Press ‘2’ to place an order. Press ‘3’ for Customer Service. Press ‘0’ to reach the Operator. Press ‘106’  
for accounting. Thank you.”  
7.3 Enabling the Voice Announcement  
For an outside line operating in the DISA mode, the voice announcement module may be enabled or  
disabled. Some hardware models do not have the voice announcement module. This parameter must be  
enabled to allow the Phone Line Manager 16 x 4 to play the voice announcement. If the voice  
announcement module is not enabled, the incoming caller will hear silence after the Phone Line Manager  
16 x 4 answers the call in the DISA mode.  
To enable the Voice Announcement Module:  
1. In the programming mode, lift the handset, enter 7806. Pause for confirmation tone.  
To disable the Voice Announcement Module:  
1. In the programming mode, lift the handset, enter 7807. Pause for confirmation tone.  
7.4 Setting the Length of the DISA Input Time  
The length of the Voice Announcement recording is fixed at 20 seconds. The length of time that the system  
waits for the incoming caller to make a choice can be set at 25 seconds or 75 seconds if the Voice  
Announcement module is enabled or it can be set at 6 seconds or 12 seconds if the voice announcement  
module is not enabled.  
To set the DISA Input Time at 75 seconds or 12 seconds:  
1. In the programming mode, lift the handset, enter 7812. Pause for confirmation tone.  
To set the DISA Input Time at 25 seconds or 6 seconds:  
1. In the programming mode, lift the handset, enter 7813. Pause for confirmation tone.  
7.5 What Happens after the DISA Entry  
After the incoming caller has entered his selection on an incoming line operating in the Auto-Attendant (or  
DISA) mode, the Phone Line Manager 16 x 4 will start ringing at an extension. While the extension is  
ringing, the caller will either hear a ringback tone or the Music on Hold input.  
To enable the Music on Hold input after DISA input:  
1. In the programming mode, lift the handset, enter 7808. Pause for confirmation tone.  
To enable the ringback tone after DISA input:  
1. In the programming mode, lift the handset, enter 7809. Pause for confirmation tone.  
If the caller specifies an extension which is not available, they will hear a short busy signal. Then the call  
will ring at the first available extension in the appropriate incoming call group if the outside line is  
configured to be a Private Incoming Line or it will ring as a Standard Incoming Line if it is so configured.  
28  
 
PHONE LINE MANAGER 16 X 4  
If the DISA call is directed to an extension which does not answer after 5 to 50 seconds, the call will  
transfer to the Operator (see Section 19.12). If the Operator does not answer after 5 to 60 seconds, the call  
will transfer to an available Rollover Extension (see Section 19.11).  
Any external music source can be used to connect Music on Hold to the Phone Line Manager 16 x 4  
®
system. You will need to plug your music source unit into the RCA jack labeled “External Music” on the  
Phone Line Manager 16 x 4. The Phone Line Manager 16 x 4 system has an internal computer-generated  
music melody source which is disabled when the RCA mini plug is inserted into the “External Music” jack.  
This music signal is heard by the incoming caller when they are placed on hold.  
7.6 What Happens If There is No DISA Entry  
If an outside line answers in the Auto-Attendant (or DISA) mode and the caller does not enter any DTMF  
digits and no fax tone is detected, the Phone Line Manager 16 x 4 can transfer the call to either the  
Operator or to the designated fax machine. You should choose for these calls to go to the fax extension if  
this outside line is used mostly for receiving faxes. This is helpful since some fax machines do not send the  
calling tone until after the called fax machine answers and thus the Phone Line Manager 16 x 4 cannot  
detect the incoming fax tone.  
You should choose for these calls to go to the Operator if the outside line is use mostly for voice callers. A  
caller using a pulse dial telephone would not be able to enter any DTMF digits and you would want this call  
to be directed to the Operator. (If the outside line is set to ring according to the Standard Incoming Line  
definition, the “Operator” setting here will cause these calls to ring extension(s) according to that  
definition. If the outside line is configured as a Private Incoming Line, the “Operator” setting will cause  
these calls to ring at the first available extension in the private incoming call list for that outside line.)  
To ring the Operator if there is No DISA entry:  
1. In the programming mode, lift the handset, enter 7856. Pause for confirmation tone.  
To ring the fax extension if there is No DISA entry:  
1. In the programming mode, lift the handset, enter 7857. Pause for confirmation tone.  
One option for a line which is to be used mostly for fax reception might be to program the outside line to  
operate in the DISA mode during the day time with this parameter set to send calls with no DTMF or fax  
input to the Operator. During the day time, the Operator would hear either silence or a fax tone and  
manually transfer the call to the fax extension. In the night mode, the outside line could be configured to  
be a Private Incoming Line, ringing only at the fax extension.  
7.7 Multiple Fax Extensions  
If a fax tone is detected on an incoming DISA call, the Phone Line Manager 16 x 4 would normally try to  
transfer the call only to the fax station associated with that outside line. In installations where you have more  
than one extension with a fax machine, this parameter allows the call to be transferred to the fax extension  
assigned to any of the CO lines. This reduces the likelihood that an incoming fax call will not have an  
available fax extension to which it can be transferred.  
To allow a fax detected on an outside line to ring at a fax extension assigned to a different outside line:  
1. In the programming mode, lift the handset, enter 7858. Pause for confirmation tone.  
To allow a fax detected on an outside line to only ring at the fax extension assigned to that outside line.  
1. In the programming mode, lift the handset, enter 7859. Pause for confirmation tone.  
If an incoming fax is detected but there is not an available fax extension, the call will ring at the Operator.

8. Central Office Lines:  
Outgoing Calls  
8.1 About Outgoing Call Groups  
The purpose of the Outgoing Call Groups is to provide the optimal management of outgoing calls, giving  
maximum outside line access to the users and extensions that need them most. The system has the capability  
to define up to four Outgoing Call Groups. Each group is a list of outside lines and every extension is  
assigned to one of these four groups. When the extension dials 9 (or 0) to make an outside call, the system  
uses the list to find the first available CO line.  
For example, an office with four outside phone lines, a fax machine, 10 employees in two departments,  
and one top executive might create the following trunk groups:  
Fax Group—You may prefer that the fax extension use only a certain outgoing line. You could create an  
Outgoing Call Group which contains the preferred outside line first with other lines also available.  
If you have an outside line dedicated solely for the use of the fax machine and you do not want anyone to  
make voice calls on this line, you may want to connect the fax machine directly to the outside line, bypassing  
the system.  
Sales Group—All extensions assigned to the sales staff might have access to all of the lines. This provides  
them with maximum access to lines on which to make sales calls.  
Tech Group—If this group needs to make fewer calls, they might be linked with only one or two outside  
lines, keeping the rest free for sales calls.  
Executive—Optionally, the executive may want a dedicated phone line for their extension, so that they  
always have a line available and can have a private number. The disadvantage would be that other extensions  
are left with one less line for outgoing calls.  
8.2 Defining Outgoing Call Groups  
You can define up to four Outgoing Call Groups. Each group can include from 0 to 4 outside lines. Each  
outside line can be included in more than one trunk group. The order in which the line numbers are  
entered (in Step 3) will determine the order in which the system searches them for availability when an  
extension dials 9 (or 0) to connect to an outside line. If you want a certain line to be tied up the least (for  
example, the fax line) but still available for outside calls, enter it last.  
1. In the programming mode, enter 73.  
2. Enter the code for the Outgoing Call Group being created:  
4
5
6
7
Outgoing Call Group #1  
Outgoing Call Group #2  
Outgoing Call Group #3  
Outgoing Call Group #4  
30  
 
PHONE LINE MANAGER 16 X 4  
If you do not want any outside lines in this Outgoing Call Group, hang up.  
3. Enter the line numbers of the outside phone line(s) that are part of this Outgoing Call Group. Enter  
one to four entries.  
1
2
3
4
Outside Line #1  
Outside Line #2  
Outside Line #3  
Outside Line #4  
Hang up. Hanging up is necessary if fewer than four outside lines were entered.  
8.3 Assigning Extensions to an Outgoing Call Group  
This feature links each extension to a specific Outgoing Call Group. It thereby defines which outside phone  
line(s) the extension can use. Any number of extensions can be assigned to a given group. This command  
must be repeated separately for each extension.  
You could assign an extension to an Outgoing Call Group containing no outside lines which would  
prohibit the extension from placing any outgoing calls.  
1. In the programming mode, enter 738.  
2. Enter the two-digit extension number (00 to 15).  
3. Enter the number of the Outgoing Call Group (1 to 4) to which this extension is assigned.  
4. Pause for confirmation tone. Hang up or continue programming.  
With default settings, Outgoing Call Groups #1 and #4 contain CO lines #1, #2, #3, and #4 in that order.  
Outgoing Call Groups #2 and #3 contain no CO lines All extensions are assigned to use Outgoing Call  
Group #1.  
31  
 
PHONE LINE MANAGER 16 X 4  
9. Direct Outward Station Access (DOSA)  
Direct Outward Station Access (DOSA) allows an incoming caller to enter a password and be connected to  
a different outside line within the system and make an outgoing call. The original incoming call must be  
directed to a CO line which is programmed to operate in the DISA mode (see Section 6.1).  
After the system answers the incoming call in the DISA mode, the caller should dial a 6 or a 7, followed by  
the 6-digit DOSA password. If the password entered matches the password stored in memory, a connection  
will be made to the first available CO line listed in Outgoing Call Group #4 (see Section 8.2).  
If the incoming caller entered a 6, the system must detect a DTMF digit within 35 seconds in order to allow  
the connection to continue. If no digit is detected after 20 seconds, a beep tone will be heard. When a digit  
is entered, the beep tone will cease. Thereafter, the beep tone will be heard every 4 minutes and a DTMF  
digit must be entered within 15 seconds to continue the call. This will prevent the situation where the  
incoming caller hangs up and the system is connected to the CO line indefinitely. In all cases, the call will  
be terminated in 15 minutes or when a Clear Forwarding/Polarity Reversal signal is detected, if enabled.  
If the incoming caller entered a 7 followed by the 6-digit password, the operation is exactly the same as for  
a 6 except there will be no prompts for DTMF digits. This can facilitate FAX and data transfers via DOSA  
since it would be impossible to enter a DTMF digit during data transmission. The 6 is still preferred for  
voice conversations so that the CO line can be released in a short time after the conversation has ended.  
If the outgoing CO line (to which DOSA is connected) is configured for pulse dialing, any digits entered  
by the caller will also be output as pulses. This conversion of DTMF to pulses will continue until either a “*”  
or “#” is entered. Thus the “*” or “#” are the preferred entry when responding to the disconnect warning  
signal so that there will not be any pulses output on the CO line.  
9.1 Enable Direct Outward Station Access (DOSA)  
The DOSA function must be enabled by the System Manager to allow an incoming caller to enter a password  
and be connected to a different CO line to make an outgoing call.  
To Enable DOSA:  
1. In the programming mode, enter 7834. Pause for confirmation tone.  
To Disable DOSA:  
1. In the programming mode, enter 7835. Pause for confirmation tone.  
9.2 Entering the DOSA Password  
The DOSA password must be specified using this command.  
Enter Password:  
1. In the programming mode, enter 764.  
2. Enter a 6-digit password. Pause for confirmation tone.

PHONE LINE MANAGER 16 X 4  
10. Hunt Groups  
Four separate Hunt Groups can be implemented, allowing a person to dial a number which will ring at the  
first available extension of that group. This can be used for intercom calls or for incoming DISA calls where  
the incoming caller can be prompted to “press 3 for sales, press 4 for technical support, etc.” There are four  
groups named as Hunt Group #2, #3, #4, and #5 and each Hunt Group can contain four extensions. The  
Hunt Groups are accessed as follows:  
To Call an extension in:  
For Intercom calls or to transfer an outside line:  
For an Incoming DISA  
caller:  
Hunt Group #2  
Hunt Group #3  
Hunt Group #4  
Hunt Group #5  
dial “122”  
dial “133”  
dial “144”  
dial “155”  
dial “2”  
dial “3”  
dial “4”  
dial “5”  
If an extension in a Hunt Group desires not to receive calls temporarily, then they may forward their calls  
to another extension or to a different Hunt Group. If an extension in a Hunt Group does not want to  
receive calls for a period of time (for example, out of the office or on vacation), then that extension should  
enter the Do Not Disturb mode.  
10.1 To Enable the Use of the Four Different Hunt Groups  
Hunt Groups must be enabled so that the Hunt Group codes will be recognized by the unit.  
To Enable Hunt Groups:  
1. In the programming mode, enter 7854. Pause for the confirmation tone.  
To Disable Hunt Groups:  
1. In the programming mode, enter 7855. Pause for the confirmation tone.  
10.2 Assigning Extensions to the Hunt Groups  
This command allows you to specify the extensions in each of the Hunt Groups.  
1. In the programming mode, enter 795.  
2. You must assign 4 extensions per Hunt Group. Enter the two-digit extension numbers (00 to 15) of the  
four extensions that will be in Hunt Group #2  
3. Repeat Step 2 for extensions in Hunt Groups #3, #4, and #5. Pause for confirmation tone.  
NOTE  
If you wish to have fewer than 4 extensions in any group, the number of one of the  
extension members should be repeated more than once to fill all four places in the group  
list.  
33  
 
PHONE LINE MANAGER 16 X 4  
We recommend that all four of the Hunt Group Lists be filled. This would prevent an incoming caller  
from accessing a vacant group if they dialed the wrong Hunt Group number. If only using two groups, then  
it may be best that the other two group extensions be entered as 00 (Operator) or another extension that  
you wish to answer the calls.  
The following table gives an example of how to use this command.  
First dial 795  
then dial 01 03 04 11  
then dial 05 06 06 06  
then dial 12 13 14 14  
then dial 00 00 00 00  
Hunt Group #2: Extension #1, #3, #4, #11  
Hunt Group #3: Extension #5, #6  
Hunt Group #4: Extension #12, #13, #14  
Hunt Group #5: Extension #0  
then pause for the confirmation tone.  
Keep a record of your Hunt Groups in the following table:  
First dial 795, then

11. Day and Night Modes  
11.1 Automatic Day/Night Mode Switching  
The Operator Extension can manually switch the system into Night Mode by dialing “56” or into the Day  
Mode by dialing 57. This command is only valid if issued from the Day mode Operator extension (see  
Section 5.2.8). It is also possible for the system to automatically switch from one mode to another at certain  
times of the day.  
To enable automatic switching between modes:  
1. In the programming mode, enter 7826. Pause for the confirmation tone.  
To disable automatic switching between modes:  
1. In the programming mode, enter 7827. Pause for the confirmation tone.  
If this automatic switching option is desired, the System Manager would need to inform the Daytime  
Operator of feature commands 56 and 57, plus the feature functions.  
The Phone Line Manager 16 x 4 can be programmed to refrain from automatically switching into the Day  
Mode on days defined as weekends (Friday, Saturday, and/or Sunday). There may be times you want to  
temporarily disable automatic switching into the Day Mode on other days due to holidays and long  
weekends. You can enter the manual switching commands (56 and 57 from the Day Mode Operator’s  
extension) which disables automatic switching. At a later time you can re-enable automatic switching to  
return to your normal schedule.  
11.2 Automatic Day/Night Mode Switching Times  
When the automatic Day/Night switching is enabled, the command to specify the switching times are as  
follows:  
1. In the programming mode, enter 794.  
2. Enter the desired 4 digits to specify the hour (00 to 23) and the minute (00 to 59) at which the system  
switches into the Night Mode.  
3. Enter the desired 4 digits to specify the hour (00 to 23) and the minute (00 to 59) at which the system  
switches into the Day Mode.

5. Pause for confirmation tone. Hang up or continue programming.  
If Automatic Day/Night Switching is enabled, the Phone Line Manager 16 x 4 will automatically determine  
(upon power up or Switching time changes) whether it should be in the Day or Night mode. For proper  
operation, it is necessary that the time specified for switching into the Day mode must be earlier in the day  
than the time specified for switching into the Night mode. Otherwise, improper operation will result.  
If the Operator enters the 56 or 57 command to manually change the operating mode, automatic  
switching will be disabled and must be re-enabled by the System Manager (if desired) by entering the 7826  
command from the System Manager’s extension.

PHONE LINE MANAGER 16 X 4  
12. Central Office Lines:  
Advanced Topics  
12.1 Tone- or Pulse-Dialing Details  
Each outside line can be set in the programming command to be a default tone (DTMF) or rotary (pulse)  
dialing type. During speed dialing or redialing, digits will be always be output in the tone mode if the  
outside line is set to tone. If the outside line is programmed to dial in the pulse mode, digits will be output  
as dial pulses until a star (*) or a pound (#) is encountered. Dialing will then switch to the tone mode. The  
initial * or # digit will not be sent to the outside line.  
In a simple connection from an extension to an outside line, extensions with ordinary phones are treated  
differently than extensions with key phones. An ordinary phone can send either DTMF tones or pulses to  
the Phone Line Manager 16 x 4. If the outside line is configured for tone dialing, the DTMF digits from the  
phone simply pass through the Phone Line Manager 16 x 4 to the outside line. If the phone sends pulses,  
the Phone Line Manager 16 x 4 will receive the entire digit and then output digit pulses onto the outside  
line using the pulse mode timing programmed by the System Manager (see Section 19.8). Note that when  
an extension invokes the Last Number Redial command, the Phone Line Manager 16 x 4 will output DTMF  
tones since the outside line is configured for tone-mode dialing, even if extension originally dialed the  
number using pulse dialing.  
If the outside line is configured for pulse dialing, the Phone Line Manager 16 x 4 can receive dial pulses  
from an ordinary phone and will receive each entire digit and then output digit pulses onto the outside line.  
If the phone is sending DTMF digits, the Phone Line Manager 16 x 4 will receive the DTMF digits and send  
dial pulses to the outside line. Note that the DTMF tones sent from the phone will be passed through to the  
outside line even though the Phone Line Manager 16 x 4 will also send dial pulses. The Phone Line  
Manager 16 x 4 will convert the DTMF tones into dial pulses until a * or a # is encountered which will  
disable pulses from being sent to the outside line for the duration of the call.  
For extensions connected to key phones, each key phone has a TONE/PULSE key which causes a light on  
the phone to be lit if the phone is in the pulse mode. In the pulse mode, digits pressed are sent to the Phone  
Line Manager 16 x 4 in computer code and the Phone Line Manager 16 x 4 will send the equivalent dial  
pulses to the outside line. Thus, unlike with an ordinary phone, DTMF tones are not passed through to the  
outside line before the dial pulses are sent. In the tone mode, the phone sends the DTMF tones which are  
simply passed through the unit to the outside line. Note that the default dialing mode set for the outside  
line only affects speed dialing and redialing operations. If a key phone sends a DTMF tone to an outside line  
which is configured to operate in the pulse mode, the Phone Line Manager 16 x 4 will only pass the DTMF  
digit dialed and will not send dial pulses. The PAUSE key on the key phone can be pressed during dialing  
which will insert a 2-second pause during a subsequent Last Number Redial.

PHONE LINE MANAGER 16 X 4  
12.2 Disconnect Supervision: Polarity Reversal/Clear Forwarding  
Some Central Office switches signal the unit when the remote party in an outside call has disconnected from  
the line. For example, if an outside call is placed on hold and during that time the outside party hangs up,  
the system will know to release the line. The Phone Line Manager 16 x 4 supports two types of signaling.  
With Clear Forward signaling, used mostly in the USA, the Central Office removes the battery feed from the  
Tip and Ring lines to signal that the remote party has disconnected. With Polarity Reversal signaling, the  
Central office reverses the polarity of the Tip and Ring signals to inform the unit when a connection has  
been completed and when it has been disconnected. If a disconnect signal is detected during an outside line  
conversation, the extension hears special tone (on for 1 second, then 2 brief beeps, then the system dial  
tone) to indicate that the call has been disconnected.  
If you are being inappropriately disconnected from outside calls, disable both of these parameters.  
To Enable Polarity Reversal Detection:  
1. In programming mode, enter 7844. Pause for confirmation tone. Hang up or continue with  
programming.  
To Disable Polarity Reversal Detection:  
1. In programming mode, enter 7845. Pause for confirmation tone. Hang up or continue with  
programming.  
When Polarity Reversal detection is enabled, the Phone Line Manager 16 x 4 software will only store the  
details of an outgoing call into Call History memory if the first polarity reversal is received, indicating that  
the connection to the called party is made. Thus if an outgoing call is made and the called phone rings for  
longer than 20 seconds but never answers, the call is not recorded.  
To Enable Clear Forward Detection:  
1. In programming mode, enter 7820. Pause for confirmation tone. Hang up or continue with  
programming.  
To Disable Clear Forward Detection:  
1. In programming mode, enter 7821. Pause for confirmation tone. Hang up or continue with  
programming.  
There are 4 DIP switches on the Trunk Board of the Phone Line Manager 16 x 4 which must be set in the  
“Up” or “Off” position to allow Polarity Reversal to be detected or in the “Down” or “On” position to allow  
Clear Forwarding to be detected.  
If the DIP switches on the Trunk Board are set differently from the system software setting, improper  
operation will result.  
If the System Manager inadvertently configures the system to detect both the Polarity Reversal and the  
Clear Forwarding signals, the system software will look only for the Polarity Reversal signal.  
38  
 
PHONE LINE MANAGER 16 X 4  
12.3 Metering Pulse Detection  
Some Central Office switches (mostly outside of the USA) send 12- or 16-KHz metering pulses to indicate  
to the system that a unit of connection time has been used. These pulses can be counted by the Phone Line  
Manager 16 x 4 and appear as part of the Call History record output. If your unit is equipped with the  
metering pulse-detection hardware, this command will enable the detection of the metering pulses.  
To Enable metering:  
1. In the programming mode, enter 7816. Pause for confirmation tone. Hang up or continue with  
programming.  
To Disable metering:  
1. In the programming mode, enter 7817. Pause for confirmation tone. Hang up or continue with  
programming.  
12.4 Metering Pulse Frequency  
If metering is enabled, you must select either 12- or 16-KHz as the frequency to be detected.  
To select 16-KHz as the metering frequency:  
1. In the programming mode, enter 7818. Pause for confirmation tone. Hang up or continue with  
programming.  
To select 12 KHz as the metering frequency:  
1. In the programming mode, enter 7819. Pause for confirmation tone. Hang up or continue with  
programming.  
12.5 Caller ID  
If your Phone Line Manager 16 x 4 is equipped with the optional Caller ID feature, this parameter should be  
enabled to allow the Phone Line Manager 16 x 4 to capture the Caller ID data sent by the Central Office  
switch between the first and second ring of an incoming call. This information will be output on the RS-  
232C port of the system to a computer equipped with appropriate translation and display software. The RS-  
232 port must be in the “Features Mode” to allow the information to be output normally or in the “System  
Mode” to allow the information to be transmitted via the CAT interface, if your Phone Line Manager 16 x 4  
is equipped with the CAT version of the software.  
To enable Caller ID detection:  
1. In the programming mode, enter 7828. Pause for confirmation tone. Hang up or continue with  
programming.  
To disable Caller ID detection:  
1. In the programming mode, enter 7829. Pause for confirmation tone. Hang up or continue with  
programming.  
It is also possible to display the Caller ID information on the LCD screen of the Key Phones. The BK-416  
EX series of key phones can display the incoming call number while the AVT-16 series of key phones can  
display both name and number.  
39  
 
PHONE LINE MANAGER 16 X 4  
In some office situations, it may not be desirable to allow all key phones to display and keep a record of  
the Caller ID information describing the name and number of incoming callers. A new parameter has been  
added to instruct the AVT-16L key phone as to whether it will display the Caller ID information as it is sent  
from the Central Office and keep a Caller ID history in memory. See Section 4.2.  
AVT-16 key phones which are not given this privilege will still be able to display the Caller ID information  
for any call which is transferred to the key phone while the call is in progress. After the key phone is no  
longer connected to the outside line, the Caller ID information is lost from that phone. Be aware that this  
parameter setting is sent to the key phone only when the key phone is first plugged in to the Phone Line  
Manager 16 x 4 system. Thus, the key phone should be unplugged from the system and then reconnected  
for a “Display Caller ID” programming change to take effect.

PHONE LINE MANAGER 16 X 4  
13. Rollover Extensions:  
Advanced Topics  
Any number of extensions can be configured to be a Rollover Extension. These extensions have special  
properties. Generally, calls directed to extensions which are busy or do not answer will be directed to an  
available Rollover Extension. Typically, extensions connected to a Voice Mail unit or to an answering  
machine would be designated as Rollover Extensions though it is possible to configure any extension to be a  
Rollover Extension. It is also possible to assign an Exclusive Answering Machine to an extension. When the  
Phone Line Manager 16 x 4 wants to ring an available Rollover Extension (due to the conditions listed  
below), it will first check to see if there is an Exclusive Answering Machine available for the extension.  
The Phone Line Manager 16 x 4 will ring an available Rollover Extension or Exclusive Answering Machine  
when:  
• An incoming call has been ringing for greater than a specified amount of time (5 to 60 seconds). See  
Section 19.11.  
• The MSG button on a key phone is pressed (if Voice Mail is enabled).  
• An intercom call was attempted to an extension which is in the Do Not Disturb mode (if Rollover on  
Intercom Calls is set). See Section 13.2.  
• An intercom call was attempted to an extension connected to an ordinary phone which is busy (if  
Rollover on Intercom Calls is set).  
• An intercom call was attempted to an extension connected to a busy key phone or to any phone which  
does not answer within five rings (if Rollover on Intercom Calls is set).  
• An outside line has been blind transferred to an extension which does not answer or parked at an  
extension which does not answer (provided the “Transfer to Operator/Rollover Extension” parameter  
specifies Rollover Extension).  
• After the Operator is rung and does not answer after a call left on hold for too long rings at the  
Operator. See Section 19.11.  
When the Phone Line Manager 16 x 4 is looking for a Rollover Extension, it checks the extensions in the  
order of physical extension #00 to extension #15 to find an extension which is both available and designated  
to be a Rollover Extension.  
13.1 Exclusive Answering Machine Privilege  
The Rollover Extensions feature allows you to specify which extension(s) will be rung when a call is directed  
to an extension which is busy or does not answer. More than one extension can be specified as a Rollover  
Extension so that a multi-channel Voice Mail unit can be attached to the Phone Line Manager 16 x 4.  
In some installations, you may want to give separate answering machines to certain people to allow  
messages intended for them to be stored and retrieved independently. This may now be done as part of the  
“Programming the Extensions” command (see Section 4.2).  
41  
 
PHONE LINE MANAGER 16 X 4  
When an extension is enabled to have the Exclusive Answering Machine privilege, the next numerical  
extension will be used as the answering-machine extension. For example, if physical extension #05 is  
enabled for this feature, calls directed to extension #05 will ring at extension #06 if extension #05 is busy or  
does not answer. If extension #06 (the answering machine) also happened to be busy, the Phone Line  
Manager 16 x 4 would look for an available Rollover Extension. Please note that calls may not be forwarded  
from the answering-machine extension (in this case extension #06) to a different extension.  
In order to use this feature, the System Manager must correctly assign the extensions such that a person’s  
answering machine is assigned to be the extension immediately after that person’s phone extension.  
Some answering machines will not respond to an incoming ring if the length of the ringing signal is too  
short. Therefore, set the distinctive ringing feature for the answering-machine extension to have the Phone  
Line Manager 16 x 4 give the longest possible ringing signal. This can be done by attaching a single-line  
telephone to the answering-machine extension and dialing 4711 at the Phone Line Manager 16 x 4 dial  
tone.  
13.2 Rollover of Intercom Calls  
You can specify when and how the Rollover Extensions are to be used. In most installations, the Rollover  
Extensions are used to take outside calls which are not answered by the desired extension. If this parameter  
is set, the Phone Line Manager 16 x 4 will also cause unanswered Intercom calls to be directed to the  
Rollover Extensions. This will occur if an Intercom call is made to (1) an extension which is in the Do Not  
Disturb mode, (2) an extension connected to an ordinary phone which is busy, (3) an extension which does  
not answer after 20 seconds, or (4) an extension connected to a key phone which is busy and does not  
answer the intercom call with 20 seconds.  
For unanswered Intercom calls to transfer to a Rollover Extension:  
1. In the programming mode, lift the handset and enter 7803. Pause for confirmation tone.  
For unanswered Intercom calls to continue ringing at the dialed extension:  
1. In the programming mode, lift the handset and enter 7802. Pause for confirmation tone.  
13.3 Rollover of Unattached Calls  
Certain outside calls which are “forgotten” can be programmed to ring at either the Operator or an available  
Rollover Extension. The types of calls affected by this setting are:  
• blind transfers to an extension which does not answer within 5 to 50 seconds (see Section 19.12),  
• calls parked at a busy extension for too long (see Section 19.6),  
• incoming DISA calls directed to a busy extension, and  
• incoming DISA calls directed to an extension which does not answer.  
To transfer unattached calls to an available Rollover Extension:  
1. At the System Manager’s extension, lift the handset and enter 7804. Pause for confirmation tone.  
To transfer unattached calls to the Operator:  
1. At the System Manager’s extension, lift the handset and enter 7805. Pause for confirmation tone.  
42  
 
PHONE LINE MANAGER 16 X 4  
13.4 Voice-Mail Unit Interface  
A Voice-Mail unit can be attached to the Rollover Extension(s) of your Phone Line Manager 16 x 4 system.  
It will have a voice announcement to enable callers to your business to access employees and/or their voice  
mailboxes. Enabling this parameter allows information to be sent from the Phone Line Manager 16 x 4 to  
the voice-mail unit to tell it the original extension dialed so that the voice-mail unit can play the appropriate  
outgoing message. Also, this parameter allows the MSG key from a key phone to be interpreted as a call to  
the voice-mail unit.  
To enable operation with the Voice-Mail unit:  
1. At the System Manager’s extension, lift the handset and enter 7824. Pause for confirmation tone.  
To disable operation with the Voice-Mail unit:  
1. At the System Manager’s extension, lift the handset and enter 7825. Pause for confirmation tone.  
13.5 Simplified Voice-Mail Interface  
When the Voice-Mail Unit Interface is enabled, the Phone Line Manager 16 x 4 will send DTMF (touch  
tone) digits to the Rollover Extension to inform the voice-mail unit as to (1) the original extension dialed  
so that the voice-mail unit can play the appropriate outgoing message, or (2) the extension dialing directly  
into the voice-mail unit to retrieve their messages.  
The Simplified Voice-Mail Interface setting has been implemented to allow the Phone Line Manager 16 x  
4 to easily interface with simpler voice mail and message-storage devices. These devices typically accept only  
a single digit to direct the caller into one of the limited number of internal mailboxes. If “Voice Mail Unit  
Interface” is enabled and “Simplified Voice Mail Interface” is also enabled, the Phone Line Manager 16 x 4  
will send only a single digit to the Rollover Extension. This digit will be the last digit in the extension’s  
physical number. Thus, a call intended for extension 104 would cause a 4 digit to be sent to the Rollover  
Extension. A call intended for extension 100 would cause a 0 digit to be sent to the Rollover Extension.  
A call intended for extension 110 would also cause a 0 digit to be sent to the Rollover Extension.  
REMEMBER: Voice Mail must be enabled (by typing 7824) for this command to cause a single digit to  
be sent to the Rollover Extension.  
To enable operation in the Simplified Voice-Mail mode:  
1. At the System Manager’s extension, lift the handset and enter 7862. Pause for confirmation tone.  
To enable operation in the Standard Voice-Mail mode:  
1. At the System Manager’s extension, lift the handset and enter 7863. Pause for confirmation tone.  
13.6 MSG Button on a Key Phone  
If the System Manager has enabled the Voice-Mail setting, a person at a key phone can press the MSG key  
and make an intercom call directly into a Rollover Extension. If the key phone extension has Exclusive  
Answering-Machine privilege, pressing the MSG key causes an intercom call to be made to the answering-  
machine extension associated with the extension.

PHONE LINE MANAGER 16 X 4  
14. Call Barring (Toll Restriction)  
14.1 About Call Barring  
The Call Barring (or Toll Restriction) feature lets you bar specific extensions from calling certain types  
of phone numbers (or prefixes). This feature is most commonly used to bar toll calls, (long-distance,  
international, and/or 1-900 number calls). If this is not a concern in your office, there is no need to  
program this feature.  
When Call Barring is operating, the system consults a Call Barring Disallow Table of phone numbers (or  
prefixes) each time a call is placed. It scans the table as each digit is entered. If a match with the Disallow  
Table is found, the call is denied. If no match is found, the call is permitted. Most commonly a Disallow  
Table will include the prefixes “1” (long-distance calls) and “011” (overseas calls).  
Exceptions to the Disallow Table are needed to allow users to call “1-800” numbers when all other  
numbers beginning with “1” are barred. In this case, you will need to create an Allow Table and enter the “1-  
800” prefix. Similarly, you can enter any other “exceptions” to numbers barred such as out-of-town suppliers  
or clients. Because the system searches the Allow Table(s) first, the Disallow Table will not bar the call.  
Creating toll restrictions requires two steps. First you will need to create one or more Disallow and Allow  
Tables. Then you will need to assign individual extensions to the appropriate table(s).  
The system can store up to three call-barring Allow Tables and three Disallow Tables. For most offices,  
one Disallow Table, or one per call group, is sufficient. But if you want to have a wide variety of restriction  
options, you can use up to three Disallow Tables and three Allow Tables.  
14.2 Call-Barring (Toll-Restriction) Details  
As an extension dials each digit, the Phone Line Manager 16 x 4 scans the complete sequence of digits  
dialed to check if the extension is barred from dialing the sequence. If the extension is restricted from  
dialing the number, the outside line is immediately released and the person at the extension will hear the  
fast error tone.  
A special case can arise if an outgoing call is made from an unrestricted extension and then transferred  
to a restricted extension. If the extension were to dial another digit, the unit would normally examine the  
complete sequence of digits dialed and determine that the extension is not allowed to make the call. The  
extension would be disconnected from the outside line. A special provision has been made to the operation  
of the Phone Line Manager 16 x 4 such that the it will not check the call barring restrictions on a transferred  
call unless and until the extension flashes in order to place the call on hold or transfer the call. This allows  
the caller to enter additional digits (perhaps to a remote voice-mail unit) without getting disconnected from  
the outside line.  
A second special case can arise if the outside lines are configured to allow a switchhook (flash) to be  
sent to the outside line. A switchhook to an outside line may be needed to affect certain features like Call  
Waiting. However, some Central Office switches may give a new dial tone in response to the switchhook. In  
this case, the caller could possibly dial an allowed number, send the switchhook, and then dial a restricted  
number. The Phone Line Manager 16 x 4 is only able to examine the digits dialed starting at the beginning  
of the sequence and the call would not be barred. If this is a concern, you may want to prohibit the  
switchhook from being sent to an outside line (see Section 6.3).  
44  
 
PHONE LINE MANAGER 16 X 4  
14.3 Filling the Call-Barring Allow and Disallow Tables  
The system can store up to three call-barring Allow Tables and three Disallow Tables. Each table has 10 slots  
(numbered 0 through 9). Each slot stores one phone number or prefix. (See the sample tables in Sections  
14.4 and 14.5.  
You must program all 10 slots for the table to work. If a slot is to be left empty, you must still program it as  
an “empty” slot by simply hanging up, as described below. You can clear all slots of all tables by following the  
instructions in Section 15.1.  
To fill a Call-Barring Allow or Disallow Table:  
1. In the programming mode, enter the code for the desired table:  
720 Allow Table #1  
721 Allow Table #2  
722 Allow Table #3  
723 Disallow Table #1  
724 Disallow Table #2  
725 Disallow Table #3  
2. Enter the number (0 through 9) of the slot you want to program.  
3. Enter the phone number or prefix you are putting in that slot (maximum of 12 digits).  
If the slot is to be left empty, hang up.  
4. Hang up. You must hang up after each slot for the programming to register.

14.6 Assigning Extensions to Tables  
Once you have generated your Call-Barring Table(s), you need to assign each extension to a table. This  
is the step that bars specific extensions from calling the numbers on the table(s). Any extension can be  
assigned to one or more tables. Extensions you do not wish to bar can be left unassigned.  
1. In the programming mode, enter 726. Enter the two-digit extension number (00 through 15).  
2. Assign the Allow Table(s) to this extension. Enter the one-digit code from the table:  
Code  
Table Assigned  
0

PHONE LINE MANAGER 16 X 4  
14.7 Password to Override Call Barring  
This feature gives you the flexibility to allow extensions to override call barring (toll restrictions) for a single  
phone call. To override Call Barring, the user must have a six-digit password. This feature would most likely  
be used if a manager will be needing to make restricted calls from any telephone in the system. It is also  
possible to restrict all extensions and require this password to be entered whenever a toll call is to be made.  
To set the Override Call Barring Password:  
1. In the programming mode, enter 763.  
2. Enter a six-digit password. Pause for confirmation tone.  
3. Hang up or continue with programming.  
To use this password, from any extension dial 40, followed by the six-digit password entered in this  
command. A confirmation tone will be given if the password is entered correctly. The extension can  
continue making unrestricted calls until it goes on hook for at least 2 seconds.  
14.8 Restrict Calls at Night  
This setting will force all extensions to use Allow Table #3 and Disallow Table #3 when the Phone Line  
Manager 16 x 4 enters the Night mode. Table #3 would typically contain a very restrictive set of dialing  
sequences, perhaps allowing only local and emergency calls.  
To force all extensions to use restrictive call barring at night:  
1. In the programming mode, enter 7830. Pause for the confirmation tone.  
To allow all extensions to use their normal call barring at night:  
1. In the programming mode, enter 7831. Pause for the confirmation tone.  
Once this parameter causes an extension to use the restricted call-barring tables, the Individual Extension  
password must be entered to remove the extension from the restricted mode. This password is entered by  
dialing 50, followed by the six-digit password which they have previously set. (The Individual Extension  
password is programmed by dialing 255 followed by the six-digit password and can only be entered while the  
extension is NOT in the restricted mode. The default value is ‘111 111’. ) When the Phone Line Manager  
16 x 4 switches back into the Day Mode, the extensions are not automatically removed from the restricted  
calling mode.  
Additionally, individual extensions can dial a code (59) which forces the extension to use the restrictive  
tables, perhaps when they leave the office for lunch or at the end of the day. At a later time, the person at  
the extension can dial 50, followed by the six-digit password to allow the extension to use its normally  
assigned call barring tables.  
47  
 
PHONE LINE MANAGER 16 X 4  
15. Assigning Speed-Dial Numbers  
This feature allows you to assign a two-digit speed-dial number for as many as 45 frequently called phone  
numbers. The assigned speed-dial numbers can be used by everyone office-wide. (The system also lets  
individual users program up to four speed-dial numbers for their extensions only.)  
When a speed-dial number is used, the system automatically accesses an outside line. This saves the step of  
dialing 9. The speed numbers are used by dialing 2, followed by the two-digit speed-dial number. From a key  
phone, you can press the MEM button, followed by the two-digit speed-dial number.  
Record your speed-dial number assignments on the following page. You may want to provide everyone in  
the office with a copy of this chart.  
To enter a speed-dial number:  
1. In the programming mode, lift the handset and enter 71.  
2. Enter a two-digit Speed-Dial number (06 to 50).  
3. Enter the phone number (up to 20 digits) that you are assigning to the code.  
To insert a two-second pause in the string of digits, switchhook (or press PAUSE from a key phone)  
4. Hang up. You must hang up after each number in order for the system to store the number.

15.1 Clear Speed-Dialing and Call-Barring Tables  
This command will erase all of the values in the global Speed-Dialing table and all of the values in the Call-  
Barring (Toll-Restriction) tables. The speed-dialing numbers assigned to individual extensions are not  
affected. This command also resets the individual extension Call-Barring passwords to their default value  
(“111111”). (See the User’s Guide for more information about individual call barring.)  
1. In the programming mode, enter 7875. Pause for the confirmation tone. Hang up or continue  
programming.  
15.2 Dial-Tone Detection  
Specially equipped versions of the Phone Line Manager 16 x 4 can be programmed to detect that a dial tone  
is present from the Central Office before a speed dial or redial operation will start sending the digits to the  
Central Office. When this command is disabled (default condition), the Phone Line Manager 16 x 4 will  
wait the amount of time set in the “Speed Dialing Delay Time” parameter before dialing the digits (see  
Section 19.14).  
Dial-Tone Detection will only operate on Phone Line Manager 16 x 4 units which contain the optional  
dial-tone detection hardware.  
To enable Dial-Tone Detection for Speed Dialing and Redialing:  
1. At the System Manager’s extension, lift the handset and enter 7840. Pause for confirmation tone.  
To disable Dial-Tone Detection and use the Speed-Dial Delay Time:  
1. At the System Manager’s extension, lift the handset and enter 7841. Pause for confirmation tone.

The Phone Line Manager 16 x 4 contains an on-board clock that contains the date and time. The system  
records into Call-History memory the details of an outgoing call which includes the date and time. The key  
phone is also able to show the date and time on its display.  
16.1 Setting the System Clock  
Setting the clock on your system allows it to correctly record the date and time when calls are made. This is  
necessary for accurate outgoing call records.  
1. In the programming mode, lift the handset and enter 729.  
2. Enter two digits each for the following settings:  
Date: 01 to 31.  
Month: 01 to 12.  
Year: 00 to 99.  
Hour: 00 to 23.  
Minute: 00 to 59.  
3. Enter a digit for the day of week (1=Sunday, 2=Monday, 3=Tuesday, 4=Wednesday, 5=Thursday,  
6=Friday, 7=Saturday).  
4. Pause for confirmation tone. Hang up or continue with programming.  
16.2 Key Phone Clock Display Format  
The key phone is capable of displaying the current time in the 12-hour mode or the 24-hour mode. For  
example, 2:00 pm in the 12-hour mode would correspond to 14:00 in the 24-hour mode.  
To display the time in the 12-hour mode:  
1. In the programming mode, lift the handset and enter 7836.  
To display the time in the 24-hour mode:  
1. In the programming mode, lift the handset and enter 7837.

17. Outgoing-Call Records and Histories  
17.1 About Outgoing-Call Records  
Each time an outgoing call lasting longer than 25 seconds is made (or the first polarity reversal is detected  
when Polarity Reversal signaling is enabled), the system stores a record of the call. The outgoing call record  
is also called Station Message Detail Recording (SMDR). Keeping the history of outgoing calls is useful for  
tracking and billing long-distance calls. If this is not a concern in your office, there is no need to program  
this feature.  
17.2 How to Output the Outgoing-Call Records  
The Phone Line Manager 16 x 4 can connect to a computer or printer via the RS-232C port. The Outgoing-  
Call Records can be output to the RS-232C port in a variety of ways.  
17.3 Output the Complete Contents of the Outgoing-Call Records  
You can choose to output the calling history for all extensions. The history shows a record for all calls made  
since the last Clear Call-History command.  
To output the complete contents of the Call-History Memory:  
1. In the programming mode, lift the handset and enter 741.  
2. The Phone Line Manager 16 x 4 will send all records, followed by the confirmation tone. Hang up or  
continue with programming.  
This procedure will tie up the programming extension until all data has been sent. No dial tone will be  
available on the System Manager’s phone. A confirmation tone will be heard when the output is complete.  
17.4 Output the Call History of a Single Extension  
You can also choose to output the Call-History records of a single extension. This command will search the  
Call-History Memory to find only those calls made by the specified extension.  
To output the Call History of one extension:  
1. In the programming mode, lift the handset and enter 742.  
2. Enter the two-digit extension number (00 to 15).  
3. The Phone Line Manager 16 x 4 will send all records, followed by the confirmation tone. Hang up or  
continue with programming.  
17.5 Clearing the Call-History Memory  
The Call-History Memory has room for about 120 records. Once the memory is full, no new records can be  
stored until the memory is cleared. It is recommended that you print out call records regularly (at the end  
of each day, week, or month), then clear the memory.  
To clear the contents of Call-History Memory:  
1. In the programming mode, lift the handset and enter 749. Pause for the confirmation tone. Hang up or  
continue with programming.  
51  
 
PHONE LINE MANAGER 16 X 4  
17.6 Output the Call History After Each Outgoing Call  
You can choose to have the Phone Line Manager 16 x 4 output the Call-History records at the end of each  
outgoing call lasting more than 25 seconds. The information will also be stored into Call-History Memory if  
space is available.  
To output the Call-History record at the end of each call:  
1. In the programming mode, lift the handset and enter 7842.  
To not output the Call-History record at the end of each call:  
1. In the programming mode, lift the handset and enter 7843.  
17.7 Automatic Call-History Retrieval Program  
The Phone Line Manager 16 x 4 allows an external computer program to retrieve the call records stored in  
Call-History memory by sending commands to the Phone Line Manager 16 x 4 via the RS-232C port. This  
feature must be enabled by the following command to allow the Phone Line Manager 16 x 4 to respond to  
these commands from the PC. Also, the RS-232C port must be in the “Features Mode” (see Section 18.1).  
To enable the Automatic Call-History Retrieval program:  
1. In the programming mode, lift the handset and enter 7852.  
To disable the Automatic Call-History Retrieval program:  
1. In the programming mode, lift the handset and enter 7853.  
There are two commands which can be sent by the computer to the Phone Line Manager 16 x 4, each  
command consisting of two ASCII characters. The characters “%’,”then “d” cause the Phone Line Manager  
16 x 4 to output the complete contents of Call-History memory. The characters “%,” then “E” cause the  
Phone Line Manager 16 x 4 to output the complete contents of Call History memory after which the Call-  
History memory is cleared. The second character (the “d” or the “E” must be sent within 120 milliseconds of  
the first character (%) for the command to be recognized.  
17.8 Formats for the Call-History Records  
Records of outgoing calls can be output in either a long format or a short format. The long format is an  
easy-to-read log. For each call, it shows in table format the line number, extension number, date and time,  
number dialed, duration of call, and the number of metering pulses. The short format organizes the same  
data in a comma delimited format, so that it can be read by call accounting software packages. The records  
will be output in short format unless you switch to the long format.  
To enable the long format for Call-History record output:  
1. In the programming mode, lift the handset and enter 7815. Pause for the confirmation tone. Hang up  
or continue with programming.  
To enable the short format for Call-History record output:  
1. In the programming mode, lift the handset and enter 7814. Pause for the confirmation tone. Hang up  
or continue with programming.

17.9 Connection to a Computer or a Printer  
To print records, the system must be connected to either a printer or a computer. The device used must  
have an RS-232C port capable of receiving data at 9600 baud. The protocol is 8 bits, 1 stop bit, and no parity.  
®
An IBM compatible PC can be connected to the Phone Line Manager 16 x 4 using a straight (not a null  
modem) cable. You can use the following procedure to retrieve Call-History records to your computer.  
1. In Windows, enter the Program Manager window, then the Accessories window. Select the Terminal  
icon.  
2. Pull down the Settings menu and select “Communications.” Verify that the communication settings are  
as follows. Change settings to match if necessary.  
Baud Rate:  
Data Bits:  
Parity:  
9600  
8
None  
Stop Bits:  
Flow Control:  
Connector:

Either COM1 or COM2, whichever corresponds to the RS-232 port being used  
3. Pull down the Transfer menu. Select “Receive Text” file. Create a new text file named “CALLS.TXT.”  
4. Once these steps are successfully completed, you are ready to receive call-history data. Enter the Call-  
History output command. This writes the data to the text file. It then can be printed out directly in the  
long format. Or you can import it in the short format into an accounting or spreadsheet program.

18. Interfacing the Phone Line Manager  
16 x 4 to a Computer  
There are many instances where the Phone Line Manager 16 x 4 can be connected to a computer to  
enhance the overall operation of the system. These include:  
• Phone Line Manager 16 x 4 Configuration Program: This program is designed to run under Microsoft  
Windows and can guide the System Manager through every detail concerning the setup of the Phone  
Line Manager 16 x 4. After the selections have been made in the program, the entire configuration  
program can be written into the Phone Line Manager 16 x 4 via the RS-232C port. There is no need to  
manually enter all of the commands detailed in this manual (see Section 18.2).  
• Call-History Reporting: The details of outgoing calls can be sent from the Phone Line Manager 16 x 4 to  
the computer. An application on the computer can collect the information into a database and generate  
useful reports. (See Section 17.9.)  
• Caller ID Processing: On Phone Line Manager 16 x 4 units equipped with the optional Caller ID  
detection capability, the unit will send the Caller ID information to the computer. An application on the  
computer can collect the information into a data base and generate useful reports (see Section 12.5).  
• Computer Aided Telephony (CAT) Interface: On Phone Line Manager 16 x 4 units equipped with the  
optional Computer Aided Telephony (CAT) software, the system can operate in a computer  
environment where it can be controlled by an application running on the computer (see Section 18.4).  
18.1 RS-232C Port—Choosing the Operating Mode  
The RS-232C port on the Phone Line Manager 16 x 4 mode can operate in one of two modes.  
• System Mode: The Phone Line Manager 16 x 4 must be in this mode in order to communicate with the  
Phone Line Manager 16 x 4 Configuration Program. It must also be in this mode to operate in the  
Computer Aided Telephony (CAT) environment (if your unit is equipped with the CAT version of the  
software).  
• Features Mode: The Phone Line Manager 16 x 4 must be in this mode to allow it to (1) output the Call-  
History information, (2) output the Caller ID data at the beginning of incoming calls (except for CAT  
units), or (3) respond to the Automatic Call-History Retrieval program running on attached computer.  
To enable the System Mode of the RS-232C Port:  
1. In the programming mode, lift the handset and enter 7851. Pause for the confirmation tone. Hang up  
or continue programming.  
To enable the Features Mode of the RS-232C Port:  
1. In the programming mode, lift the handset and enter 7850. Pause for the confirmation tone. Hang up  
or continue programming.

PHONE LINE MANAGER 16 X 4  
18.2 Phone Line Manager 16 x 4 Configuration Program  
This program is designed to run under Microsoft Windows and can minimize the need to manually enter all  
of the commands detailed in this manual. To use the program, simply insert the diskette into your computer  
and enter A:\SETUP or B:\SETUP from the FILE,RUN menu in Program Manager (or the START, RUN  
menu in Windows 95). There are still some instances where you will need to use the telephone at the System  
Manager’s extension to set certain features or operating modes. These are:  
• Set the mode of the RS-232C serial port. The “System Mode” must be set to allow the configuration  
program to communicate with the Phone Line Manager 16 x 4. This mode must also be set for the CAT  
version of the Phone Line Manager 16 x 4 software to function. The “Features Mode” is enabled to allow  
it to (1) output the Call-History information, (2) output the Caller ID data at the beginning of incoming  
calls (except for the CAT version of the software), or (3) respond to the Automatic Call-History Retrieval  
program running on attached computer.  
• The message in the voice announcement module can only be recorded from extension #15 when that  
extension is designated as the System Manager. (See Section 7.2).  
• If a person loses their Individual Call-Barring Password, enter the first part of the Configure Extension  
command. Enter 75 nn then hang up. nn is the physical extension number 00 to 15 (see Section 4.2).  
• Manually output the Call-History Buffer contents to the RS-232C port (See Section 17.3).  
• Clear the contents of the Call History buffer (see Section 17.5).  
• Reset the entire system to default values (see Section 3.7).  
• Set the date, time, and the day of the week (see Section 16.1).  
18.3 Phone Line Manager 16 x 4 Configuration Program—Remote Operation  
It is possible for a computer running the Configuration Program in one location to communicate with an  
Phone Line Manager 16 x 4 unit at another site.  
Remote configuration is enabled when the System Manager enters the 772 command. When this  
command is entered, the Phone Line Manager 16 x 4 will answer the next incoming Central Office call in  
the DISA mode. If the incoming caller enters an 8, the unit will enter a mode allowing a remote program to  
configure the Phone Line Manager 16 x 4 via tones sent through the incoming line. An external modem is  
not required. A special translation unit is required at the host computer site in order to allow the standard  
PC-based Phone Line Manager 16 x 4 Configuration Program to connect to the remote Phone Line  
Manager 16 x 4.  
In this configuration mode, the resources required for answering calls in the DISA mode will be in use.  
Therefore, all incoming calls will be answered in the non-DISA mode for as long as the configuration  
process is in progress.  
NOTE  
The ability to remotely program by using an external modem at the Phone Line Manager 16  
x 4 unit site (using the 771 command) which was supported by earlier versions of the  
software is no longer supported.  
55  
 
PHONE LINE MANAGER 16 X 4  
18.4 Computer Aided Telephony (CAT) Software  
The Computer Aided Telephony (CAT) version of the Phone Line Manager 16 x 4 software can operate in  
a computer environment where it can be controlled by an application running on the computer. All of the  
modes and commands discussed in this manual will operate as described. A person at any extension can use  
all of the features listed. However, there may be other commands and capabilities which can be accessed  
from the computer application controlling the Phone Line Manager 16 x 4.  
18.5 Report DISA Digits to the CAT Application  
The CAT software can be configured to send a message to the CAT application as each digit is entered by an  
incoming caller to an outside line configured to operate in the DISA mode. In this mode, the Phone Line  
Manager 16 x 4 will not try to interpret the digits entered. It will not cause the call to ring at any extension.  
The CAT application would typically process the digits entered and send a command to the Phone Line  
Manager 16 x 4 causing the incoming call to ring at a specified extension.  
To report incoming DISA digits to the CAT Application:  
1. In the programming mode, lift the handset and enter 7860. Pause for the confirmation tone. Hang up  
or continue programming.  
To enable the normal mode of DISA operation:  
1. In the programming mode, lift the handset and enter 7861. Pause for the confirmation tone. Hang up  
or continue programming.

19. System Timing Parameters  
19.1 About System Timing Parameters  
The default value for the system timing parameters should be suitable for most applications and will never  
need to be changed. There may be some changes you will want to make which will affect the operation of  
the system under certain conditions. Any changes made affect all outside lines and all extensions.  
19.2 Changing System Timing Parameters  
The command to change the system timing parameters requires that each setting be entered in the order  
shown. If you are modifying only a few of the settings in the list, you should enter the default value, shown  
with an “*” for other parameters which you do not intend to change.  
1. In the programming mode, enter 727.  
19.3 Delay After Each RS-232C Character  
This determines the amount of delay inserted after a character is sent across the RS-232C port to the printer  
or PC. This setting is important only if you directly connect a computer or dedicated printer to the RS-232C  
port.  
2. Enter the two-digit code for the character delay

19.5 Switchhook (Flash) Timing  
This is the minimum amount of time necessary to perform a switchhook. If the switchhook is pressed for less  
than this amount of time, the system recognizes it as a dial pulse and not as a switchhook (or flash). The  
“200 ms” and “300 ms” entries have been included because some phone instruments do not go onhook  
cleanly and this can cause an outside call to be inadvertently placed on hold when trying to hang up on the  
call. The longer switchhook times can help to compensate for these phones.

This parameter sets the amount of time an extension will ring in certain situations before the call is  
transferred to the Operator or a Rollover Extension.  
An extension specified by an incoming caller in the DISA mode will ring for this amount of time before  
being transferred to the Operator or a Rollover Extension.  
If an extension places a call on hold for too long and then does not answer after the Phone Line Manager  
16 x 4 calls back, the call will be transferred to the Operator or Rollover Extension after this amount of time.  
If a call is transferred to an extension and the transferring extension hangs up (blind transfer), the call  
will ring for this amount of time before being transferred to the Operator or a Rollover Extension.
