Security

As a customer of new telecommunications equipment, you should be aware of the significant and
growing problem of theft of long distance services by third parties, known commonly as “toll fraud.”

It is particularly important that you understand and take appropriate steps to deal with this crime

because under applicable tariffs, you will be responsible for payment of associated toll charges.
AT&T cannot be responsible for such charges and will not make any allowance or give any credit
resulting from toll fraud.

Toll fraud can occur despite the preventive efforts of network providers and equipment
manufacturers. Toll fraud is a potential risk for every customer with telecommunications equipment
having one or more of the following features: (1) remote access, (2) automated attendant, (3) voice
mail, (4) remote administration and maintenance, and (5) call forwarding (remote). This is not a
product or design defect, but a risk associated with equipment having one or more of the features
described above. If your new telecommunications equipment possesses any of these features,
please consult the relevant portion of your documentation for further details and specific procedures
to reduce the risk of toll fraud or contact your AT&T dealer for further details.

extra alerts.

System Components

Modular hardware design makes the system easy to install and expand. Figure

1-1 shows an example of system components.

Control Unit

The control unit is the heart of the system; it includes a backplane and a cover,
and it houses the system modules. All system modules slide into the
backplane, which channels power to the system. The cover slides onto the front
of the backplane after all the system modules have been installed.

WARNING:

There are no customer-serviceable components inside the system
modules or backplane. There are hazardous voltages within that can
cause severe or fatal personal injury. DO NOT OPEN THE MODULES.

*

If you use music-on-hold to broadcast certain copyrighted music or material, including songs or other

material from radio broadcasts, you may be required to obtain the permission of the copyright owner. One
way to obtain permission is to contact ASCAP, BMI, and/or similar performing rights organizations, to obtain
a license. Or, you can purchase a Magic on Hold® system from AT&T, which does not require you to obtain
such a license. AT&T disclaims any liability arising out of the failure to obtain such a license, if required.

System Modules

The following system modules can be installed in your system:

■

■

■

Processor Module provides the software intelligence that controls the
system’s features. It has jacks for a music-on-hold audio source, a
loudspeaker paging system, and a call reporting (SMDR) device, such as
a printer.

206E Module has jacks to connect a maximum of two outside telephone
lines and six extensions to the system. You can connect telephones and
other telecommunications devices (such as fax machines and modems)
to the extension jacks (either directly or through your building’s modular
wall jacks). Each 206E module has a green power indicator that shows it
is receiving power. The system requires at least one 206E module.

400E Module is similar to the 206E module, but without extension jacks.
It has four outside line jacks. This module is an inexpensive way to add
lines when you do not need more extensions.

If you are upgrading from a PARTNER system or a previous release of a
PARTNER Plus system, you can still use its 200 modules, each providing two

line jacks.

If you want message waiting capability on standard phones that are equipped
with message waiting lights, you must connect those phones to extension jacks
on Release 3.1 (R3.1) 206 modules. Additionally, you need an R3.1 processor
module.

Hereafter, references to 206 modules include 206E and all 206 modules used
with previous releases of the product. Similarly, references to 400 modules
include 400E and all 400 modules used with previous releases of the product.

System Capacity

The combination of 206 and 400 modules installed determines the number of
available lines and extensions. The system allows up to 12 lines and up to 24
extensions; however, these maximums cannot be achieved simultaneously:

■ For maximum line capacity (12 lines), install two 206 modules and two

400 modules. This arrangement allows up to 12 extensions.

■

For maximum extension capacity (24 extensions), install four 206
modules. This arrangement allows up to 8 lines.

Telephones
System Telephones

This guide refers to AT&T telephones specifically designed to work with the

system as system phones. These include the MLS-34D, MLS-18D, MLS-12D,
MLS-12, MLS-6, and MLC-6 telephones.

System phones have several buttons in common: volume control buttons, and

the

buttons. In addition, each phone has
programmable buttons that can be used for outside lines, extension numbers,
outside phone numbers, or system features. Outside lines, as well as some
system features, require buttons with status lights. Programmable buttons
without lines assigned to them can be programmed with numbers or features, so
you can use the feature or dial the number with one touch. The number in each
model name indicates the number of programmable buttons with status lights
plus two

buttons.

If the system phone has a display, indicated by a “D” in the model name, users
receive messages and prompts when making calls and programming. (More
information about the display is provided in Chapter 5.) A system display phone
is required for system programming. It must be as large as the largest phone in
the system, because an MLS-12D or MLS-18D cannot program an MLS-34D.
Similarly, an MLS-12D cannot program an MLS-18D.

Intercom Autodialers

The system phones at extensions 10 and 11 each support one MLS-CA24
Call Assistant™ Intercom Autodialer, which provides Auto Dial buttons for all of
the extensions in your system (up to 24). The Auto Dial buttons allow users to
dial and transfer calls to system extensions with one touch. The status lights for
the buttons also indicate calling activity at each extension. For more
information, see “Auto Dialing” in Chapter 5.

*

The MLS-34D has 32 programmable buttons with status lights and the MLS-18D has 16 programmable

buttons with status lights. Since the system supports a maximum of 12 lines, you can use up to 12 buttons

on these phones for outside lines.

Overview

1-5

Standard Telephones

You can also use industry-standard single-line rotary or touch-tone telephones,

including feature phones with built-in feature buttons and lights, with the system.
This guide refers to such telephones as standard phones. AT&T-certified
standard phones, such as the 8110 Analog Telephone, are recommended.

The following standard phones with message waiting lights are compatible with
the system:

■

■

Single-Line Telephone with Message Waiting Light and Recall Button

(2500 YMGK)
7102 Plus Analog Voice Terminal

Check with your local AT&T Authorized Dealer to find out if other standard

phones with message waiting lights will work.

NOTE:

For message waiting capability, you must connect standard phones with
message waiting lights to Release 3.1 (R3.1) 206 modules, and equip the
system with an R3.1 processor module. This message waiting capability does
not apply to standard phones with neon-type message waiting lights.

Auxiliary Equipment

You can connect many types of telecommunications devices to your system

without expensive adapters or additional phone lines. Many industry-standard,

single-line devices will work with the system regardless of the manufacturer:

■

■

■

■

■

Touch-tone, rotary, and cordless telephones (such as those you might
have in your home)

Fax machines
Answering machines

Modems

Credit card scanners

There are several other devices that may be compatible with the system. For

more information, refer to the list in Chapter 4 or contact your local AT&T

Authorized Dealer. Also, see Chapter 4 for advice on setting up auxiliary

equipment to work effectively with the system.

1-6

Overview

Requirements

An industry-standard device must meet the following conditions:

It must be non-proprietary. That is, it cannot be made specifically for use
on a particular telephone system. (For example, you cannot connect an
AT&T MERLIN® phone because it is specifically designed for use on a
MERLIN system.)

Its Ringer Equivalence Number (REN*) cannot be greater than 2.0. (The
REN is shown on a label on the device, usually on the bottom.)

■

■

■

You can connect a standard two-line device to the system, but for best

results it should be installed and used as if it were a single-line device.

Connecting Standard Devices

You can connect a standard device so that it is on an extension by itself, or so
that it shares an extension with another piece of equipment (either another
standard device or a system phone) as long as the REN of the two devices
together does not exceed 2.0. (System phones have 0.0 REN.) For example,
you can connect a standard phone and an answering machine to the same
extension. An extension with two devices connected to it is called a
combination extension. You cannot connect two system phones on one
extension. The PARTNER Plus Communications System Installation guide
provides installation instructions.

*

REN is a measure of the power it takes to ring a phone. The typical home phone line handles 4.0–5.0 RENs;
each extension jack in your system handles up to 2.0 RENs.

Programming

Overview

After the system hardware is installed, you can customize the system and
individual telephones. This chapter explains how to use programming to
accomplish that.

There are two types of programming:

■

System Programming allows you to customize the system to meet the

needs of your business. When the system is first installed, it uses factory

settings that reflect the most commonly used options. You can change

system settings as needed.

You can perform System Programming from either extension 10 or 11.

Because an extension cannot be in programming mode and handle

calls at the same time, consider using extension 11 for programming.

Doing so gives you the ability to program without disrupting call

handling by the receptionist at extension 10.

■ Telephone Programming allows telephones to be customized to meet

individual users’ needs. Individual telephones can be programmed either
from extension 10 or 11 (called Centralized Telephone Programming), or
from a user’s extension using a system phone (called Extension

Programming).

A system display phone is required for System and Centralized Telephone
Programming. Make sure that the programming phone is as large as the largest
phone in the system, because an MLS-12D or MLS-18D cannot program an
MLS-34D. Similarly, an MLS-12D cannot program an MLS-18D.

This chapter provides general information on programming procedures. When a
specific feature name is referenced, it is printed in bold type. For detailed
descriptions and step-by-step instructions, refer to that name in Chapter 5.
(Brief summaries of all programming procedures are at the end of this book.)

Programming

2-1

Hardware Considerations

Programming procedures use line and extension numbers. The line number
represents the line jack on a 206 or 400 module to which the outside line is
connected. Similarly, the extension number represents the extension jack on a
206 module to which the system phone or standard device is connected.

For each 206 module, the system assigns two lines and six extensions; for each
400 module, the system assigns four lines. The system numbers lines and
extensions consecutively. Figure 2-1 shows the numbering scheme for a
system with maximum lines. Figure 2-2 shows the numbering scheme for a
system with maximum extensions. However, your system can have any number
of lines and extensions up to the maximum.

Programming

Initial System Setup

After the control unit is installed, you set up the system using a combination of
system and telephone programming procedures. In this guide, System
Programming procedures are identified by a code (# and three digits);
Telephone Programming procedures are identified by the feature name only.

Use the System Planner as a guide when programming. The following sections
provide an overview of the procedures you use for initial system setup. See
Chapter 5 for more information on specific procedures. Other programming
procedures are optional, but strongly recommended to make the most of your
investment. (See “System Programming Options” and “Telephone Programming
Options” later in this chapter for details.)

Setting the System Clock

After supplying power to the control unit, use the following procedures:

■

System Date (#101) to set the month and day.

■

System Day (#102) to set the day of the week.

■

System Time (#103)

to set the hour and minutes.

Assigning Lines

For initial setup only, use Number of Lines (#104) to specify the number of lines
that will be assigned to all system extensions. Then use the following
procedures as needed:

■

■

■

■

■

Dial Mode (#201) to identify any rotary lines (the default for all lines is
“touch-tone”).

Line Assignment (#301) to assign lines to specific extensions (if the line

was not assigned using the Number of Lines procedure), to remove lines
from some extensions, or to change the button used to pick up a line at a

specific extension.
Line Access Restriction (#302) to limit an extension’s access to a

specific line.
Line Ringing (Centralized Telephone Programming) to specify when a

line will start ringing at each extension that has the line. For additional
information on line ringing options, see “Programming a Receptionist’s
Extension” later in this chapter.

Automatic Line Selection (Centralized Telephone Programming) to

specify the order in which the system tries to select an available line

(intercom or outside), when a user at the extension lifts the handset or

presses

 Spkr  to make a call without first selecting a specific line button.

For extensions with standard phones, set Automatic Line Selection
to intercom first. This enables standard phones to access equipment
features, including intercom calling. When users lift the handsets on
standard phones, they hear intercom dial tone. To access an outside
line, they must dial 9.

Display Language (#303) to specify the language (English, French, or

Spanish) for messages that appear on a system display phone.

Automatic Extension Privacy (#304) to prevent other extensions with
the same line from joining a call at the extension. This feature is also
useful for extensions connected to a modem, fax, or any device whose
function can be disrupted by someone trying to join it.

Forced Account Code Entry (#307) to prevent the extension from
making an outside call until a required account code is entered. You can
also use Forced Account Code List (#409) to create a list of valid

account codes.

Outgoing Call Restriction (#401) to prevent the extension from making
certain types of outgoing calls (on all system lines).

Disallowed List Assignments (#405) to assign one or more Disallowed
Phone Number Lists to the extension. Use Disallowed Phone Number
Lists (#404) to create the lists of outside numbers that extensions cannot
dial.

Allowed List Assignments (#408) to assign one or more Allowed Phone
Number Lists to the extension. Use Allowed Phone Number Lists (#407)
to create the lists of outside numbers that otherwise-restricted extensions

can dial.

Pickup Group Extensions (#501), Calling Group Extensions (#502),
Night Service Group Extensions (#504), and Hunt Group Extensions
(#505) to place the extension in any of these groups. See “Setting Up

Groups of Extensions” later in this chapter for more information.

Fax Machine Extensions (#601), Doorphone Extension (#604 and

#605), Doorphone Alert Extensions (#606), or AA Extensions (#607) to

identify the extension as one of these equipment types.

“Setting Up Auxiliary Equipment” later in this chapter provides an overview of
the procedures you use for setting up devices, such as hotline phones, voice
messaging systems, and call reporting devices. Also, Chapter 4 provides
detailed information and example applications for auxiliary equipment.

Copy Settings

The recommended way to set up your system is to program one extension for
each type of phone in the system, then use Copy Settings (#399) to program
other phones of the same type. For example, you can program one MLS-12D
phone and then copy its settings to any other extensions that have MLS-12D or
MLS-12 phones. See “Copy Settings” in Chapter 5 for a list of the programmed
settings that are copied.

Programming

Changing Settings after Installation

As your business grows or changes, you will probably need to change the way
your system was originally programmed. This section provides some examples
and lists the procedures you would use to change settings after installation. For
specific details on a procedure, refer to the procedure name in Chapter 5.

Changing the System Clock

You may need to change the system clock for daylight saving time, after a

prolonged power failure, or after a system reset. Use System Date (#101),
System Day (#102), and System Time (#103) to set the current date, day, and

time.

Adding New Lines

If you add an outside line to your system, you may need to adjust some line
settings. In particular, use Dial Mode (#201) if the new line is a rotary line, Line
Assignment (#301) to assign the line to specific extensions, Line Ringing
(Centralized Telephone Programming) to specify when the line will start ringing
at each extension that has the line, and Line Access Restriction (#302) to limit
an extension’s access to the line. Additionally, the system automatically assigns
the new line as the last line in the Automatic Line Selection sequence. If you

want to change the order, use Automatic Line Selection (Centralized
Telephone Programming).

IMPORTANT:

Do not use Number of Lines (#104) if you add lines to the system after initial
setup, because it changes Line Access Restriction (#302), Automatic Line
Selection, Line Ringing, and Hold Disconnect Time (#203) for existing lines
back to factory settings. To change line assignments without affecting other
settings, use Line Assignment (#301).

Adding New Extensions

If you add an extension to your system, you can probably use Copy Settings

(#399) to copy the settings of an existing extension. If you wish to further adjust

a new extension’s settings, see “Customizing Extensions” earlier in this chapter.

Swapping Extensions

If a user changes physical locations but wants to keep the same extension

number, you can make the change easily by swapping modular connections at

the control unit.

For example, if the users at extensions 29 and 32 switch offices, you can

disconnect the modular plug from extension jack 29 in the control unit, and

reconnect it at extension jack 32. Likewise, unplug the wire that was connected

to extension jack 32 and reconnect it at extension jack 29. Then, the users can

take their respective phones to their new location to keep the same extension

number and retain the phone’s programmed settings.

Changing Settings to Support
PBX or Centrex Services

■

■

This section applies only if you use PBX or Centrex services with your system. If
it does not apply, go to the next section, “System Programming Options.”

PBX services are provided by a private telephone switch.

Centrex services are provided by your local telephone company from a
Central Office (CO) outside your premises. These services include the
Centrex lines connected to your control unit modules and some set of
features—such as hold, conference, or transfer—that are available on
those lines. Centrex services may be offered in your area under a
different name. For specific Centrex features to be available to you, your
company must subscribe to those features. For specific information on
using Centrex, see the Centrex documentation provided by your local
telephone company.

Some of the issues you should consider when setting up your system to work
effectively behind a PBX or Centrex system are discussed below. Chapter 5
explains how to use the programming procedures discussed here.

Recall Setting

To set up your equipment to work properly with a PBX or Centrex system, first
set Recall Timer Duration (#107) to match the setting used by your PBX or
Centrex system (usually 800 msec., or “32”). This setting affects the length of a
Recall signal sent by the control unit to access Centrex services.

Dialing Restrictions

Outgoing Call Restriction (#401) is an equipment restriction intended to limit
an extension’s dialing to “inside calls only” (using the

 Intercom  buttons on

system phones) or to “inside and local calls only” (allowing calls within the PBX
or Centrex system and local calls outside the PBX or Centrex system).
However, if users in your system use a dial-out code (9 on most PBX or Centrex
systems) before dialing numbers outside the PBX or Centrex system, the
equipment will not be able to prevent toll calls for extensions restricted to “inside
and local calls only” (unless you use Disallowed Phone Number Lists to prevent
dialing to specific classes of numbers).

If your PBX or Centrex system includes dialing restrictions, use those instead of
the equipment restrictions. If you have PBX or Centrex dialing restrictions on a
line and also program equipment restrictions, both the PBX or Centrex system
and equipment restrictions apply. However, equipment dialing permissions will
not override PBX or Centrex system restrictions.

Speed Dial and Auto Dial Numbers

When you program numbers outside the PBX or Centrex system as Speed Dial
and Auto Dial numbers, include the PBX or Centrex system dial-out code (9 on
most PBX or Centrex systems), followed by a pause, in the stored number.

2-6

Programming

System Programming Options

This section discusses programming options that involve multiple procedures
(such as dialing restrictions and auxiliary equipment settings), as well as
features that can be used throughout your system (such as Speed Dialing). You
can use a combination of programming procedures to set up your system to
operate most efficiently, taking into account your company’s telephone service,
personnel, and equipment, as well as the special needs of particular
departments. This section lists the procedures you can use; for details on using
a particular procedure, refer to the procedure name in Chapter 5.

Speed Dialing

You can program up to 60 frequently dialed phone numbers—such as
suppliers, repair services, customers—so that all users in the system can dial
them by pressing three buttons:



Feature



(or

 # 

on a standard phone) plus a

two-digit code. These are called System Speed Dial Numbers.

Dialing Restrictions and Permissions

The system has several procedures for restricting telephone use, and several for
overriding those restrictions. You can use any combination of these procedures
to design a system that meets your needs.

When a user makes a call, the system checks the number dialed against all of
the dialing restrictions that apply to the extension making the call. When the
number dialed passes a restriction, it goes to the next one, if necessary. When
a number violates a restriction, the call is stopped and the user hears a reorder
tone (fast busy signal).

IMPORTANT:

While procedures that restrict dialing are very effective, absolute protection
against misuse cannot be guaranteed. System phones give more protection
than standard phones. Therefore, we strongly recommend that you install
system phones where restricting phone use is important.

Restricting Access to Outside Lines

A user can access a line either by pressing the line button on the phone or by
dialing a feature code (Direct Line Pickup). If you do not want a user to access
a specific outside line, you can use Line Access Restriction (#302) to control
an extension’s access to a certain line (whether the line is assigned to the
extension or not). Table 2-1 provides examples of settings that can be used to
restrict an extension’s access to a specific outside line.

NOTE:

If Forced Account Code Entry (#307) is programmed for an extension, that
extension is required to enter an account code before dialing an outside
number—even those on the

Emergency Phone Number List (#406)

— on all of
the lines assigned to that extension. If Forced Account Code List (#409)
contains entries, the system checks the account code against the list. If the
account code is on the list, line access is allowed; if not, line access is denied.

Programming

2-7

Controlling Calls on Outside Lines

When an extension is allowed access to an outside line, you can use the
following procedures to control calling:

■

■

■

Outgoing Call Restriction (#401) defines the type of calls (inside only,

local only, or inside, local, and long-distance) that users can make from

all lines available on an extension. Outgoing Call Restriction Button
(#114) allows the receptionist at extension 10 to quickly change an

extension’s current Outgoing Call Restriction setting.

Disallowed Phone Number Lists (#404) creates up to four lists of
numbers that cannot be dialed. After creating Disallowed Phone Number
Lists, use Disallowed List Assignments (#405) to assign one or more
lists to a specific extension.

Night Service with System Password (#403) restricts users at
extensions in the Night Service group from dialing outside phone
numbers (except Emergency numbers and Marked System Speed Dial
numbers) unless the password is entered first.

Table 2-2 provides examples of settings that can be used to restrict an
extension’s dialing once it gets an outside line.

Overriding Dialing Restrictions

The following programming procedures provide ways to override all dialing
restrictions, provided the user has access to an outside line:

■

■

■

Emergency Phone Number List (#406) defines a list of up to ten
numbers that can be dialed from any extension. A typical number is 911.

Marked System Speed Dial Numbers are specially identified System
Speed Dial numbers, which a user can dial by pressing

 Feature  (or  # 

on a standard phone) followed by a two-digit code.
System Password (#403) creates a password that can be entered at any

system phone (except an MLC-6) to override dialing restrictions for the
duration of a call.

To override all dialing restrictions except Line Access Restriction (#302) and

Night Service with System Password (#403), use Allowed Phone Number
Lists (#407) to create lists of outside numbers that otherwise-restricted

extensions can dial. Then use Allowed List Assignments (#408) to assign one
or more of the lists to an extension.

2-8

Programming

Summary

Tables 2-1 and 2-2 summarize the available dialing restrictions and permissions,
showing how they can be combined in a variety of ways to customize an
extension’s dialing privileges.

If a line is not assigned to the extension, a user can use Direct Line Pickup to access the line. Emergency
numbers, Marked System Speed Dial numbers, Allowed Phone numbers, and numbers dialed using the
System Password override all dialing restrictions if a user has access to an outside line to place the call. If
Forced Account Code Entry is programmed for an extension, the user must enter an account code before

accessing an outside line. If there are entries in the Forced Account Code List, the entered account code
must match an entry on that list.

Programming

2-9

Setting Up Groups of Extensions

You can set up four types of extension groups:

■

■

■

■

Pickup Group Extensions (#501) assigns extensions to one of four
Pickup Groups. A Pickup Group lets any user in the system answer
outside calls for any extension in that group.

Calling Group Extensions (#502) assigns extensions to one of four

Calling Groups. A Calling Group lets users ring or page all extensions in
that group simultaneously.

Night Service Group Extensions (#504) assigns extensions to the Night
Service Group. When Night Service is activated at extension 10, calls
ring immediately at Night Service extensions regardless of how they ring
at other times (only the lines assigned to an extension will ring).

Hunt Group Extensions (#505) assigns extensions to one of seven Hunt

Groups. (Hunt Group 7 is used exclusively for the voice messaging
system.) A Hunt Group lets users ring or voice signal the first available
(non-busy) extension in that group. If a ringing call is not answered, the
system tries each available extension in turn until the call is answered. If
a voice-signaled call is not answered, the call does not keep hunting.
Also use Group Call Distribution (#206) to assign outside lines to a Hunt
Group if you want outside calls to ring directly into a group.

Setting Up Auxiliary Equipment

The following programming procedures help you manage auxiliary equipment.
See Chapter 4 for more information on auxiliary equipment configurations or
refer to Chapter 5 for details on using the procedure:

■

■

■

■

■

Fax Machine Extensions (#601) identifies extensions to which fax
machines are connected.

Music on Hold (#602) activates or deactivates the MUSIC ON HOLD jack
on the processor module. When this jack is activated and an audio
source is connected, callers hear recorded music or messages while on
hold. Also, Background Music lets users with system phones (other
than the MLC-6) play the recorded material through their phone’s speaker
when the phone is not in use.

Hotline (#603) identifies hotline extensions, so when a person lifts the
handset of the hotline phone, a predetermined extension automatically

rings.
Doorphone Extension (#604 and #605) identifies extensions to which

doorphones are connected. Doorphone Alert Extensions (#606)
identifies extensions that signal when the doorphone button is pressed.

AA Extensions (#607) identifies extensions to which PARTNER

Attendants are connected. This lets the system notify users with display
phones when they are receiving a call that has been transferred from the
PARTNER Attendant. Also, Transfer Return Extension (#306) lets you
identify the extension to which a call transferred by the PARTNER
Attendant should be routed if the destination extension does not answer.

2-10

Programming

■

■

SMDR Record Type (#608) specifies the type of calls that you want to
record for call reporting—either all calls or outgoing calls only. Account
Code Entry lets users specify account codes for outside telephone calls;
if used, the account codes are included on the call report. SMDR Top of
Page (#609) notifies the system that the printer has been aligned to the
top of a new page.

The voice messaging system uses the following procedures:

– Hunt Group Extensions (#505) assigns the extensions associated

with the voice messaging system hardware to Hunt Group 7—the VMS
Hunt Group. (The PARTNER MAIL VS system uses two extensions;
the PARTNER MAIL system uses two or four extensions.)

– Group Call Distribution (#206) assigns lines to the VMS Hunt Group

so calls can ring directly into the voice messaging system and receive
Automated Attendant Service or directly into the voice mailbox of a
specific subscriber.

–

VMS Hunt Delay (#506) determines when outside calls should be
answered by the Automated Attendant Service of the voice messaging
system. You can set the system for either immediate call handling or
delayed call handling. The setting you select is used for both day and
night operation.

–

VMS Hunt Schedule (#507) determines when outside calls should
ring the VMS Hunt Group (always, day only, or night only) depending
on the status of the Night Service Button (#503) at extension 10.

–

Automatic VMS Cover (#310) determines whether or not an
extension’s unanswered intercom and transferred calls are
automatically covered by the voice messaging system.

– Transfer Return Extension (#306) identifies the extension to which a

call transferred by the voice messaging system should be routed if the
destination extension does not answer and does not have voice mail
coverage active. (The transfer return extension for the voice
messaging system is typically extension 10.)

Hospitality Features

The following hospitality features are for special applications, such as the Bed

and Breakfast and Hotel/Motel industries:

■

■

Outgoing Call Restriction Button (#114) lets you program a button on
the system phone at extension 10 to change an extension’s current
Outgoing Call Restriction setting without entering System Programming
mode. For example, after a guest’s departure, a hotel manager can
change the No Restriction setting of the guest room phone to Inside Only
so outside calls cannot be made from the phone after the guest checks
out.

Wake Up Service Button (#115) lets you program a button on the system
phone at extension 10 to be used for scheduling wake-up or reminder
calls for specified system extensions.

Programming

2-11

Using System Programming

System Programming changes settings for the system as a whole, or for

individual lines or extensions. You can also use System Programming to set up
dialing restrictions, define groups, or set up auxiliary equipment. Refer to the
filled-out System Planner when you are changing system settings, and be sure
that any changes in programming are recorded there.

The Programming Overlays

System Programming requires a programming overlay placed over the dial pad

of the MLS-34D, MLS-18D, or MLS-12D system phone at extension 10 or 11.

(Overlays are provided with the system documentation. Replacements can be
ordered through the AT&T Sourcebook.) Figure 2-3 illustrates the programming

overlays.

During System Programming, the normal functions of several buttons on the

display phone at extension 10 or 11 change. For example, the left

 Intercom 

button becomes  System Program , the button used to enter programming mode.

The programming overlay identifies these buttons.
You use the following special buttons while programming:

■

■

■

■

■

■

■

■

■

 Next Procedure  and  Prev Procedure  cycle forward and backward through

the programming procedures. You can use these buttons to select a
procedure.

 Next Item  and  Prev Item  cycle forward and backward through a

procedure’s parameters. A parameter is typically an outside line, an
extension, or a telephone list entry.

 Next Data  and  Prev Data  cycle forward and backward through the valid

entries. These buttons work only for fixed data, such as a line or
extension number. They do not work for variable data such as date, time,
password, telephone numbers, or doorphone assignments.

 Remove  returns the current setting to the factory setting—or when using

Line Assignment (#301), removes lines from an extension.

 Enter  ends an entry of variable length, such as a telephone number in an

Allowed Phone Number List.

Telephone Programming Options

System telephones are ready to use when they are installed, but they can be
customized to meet the needs of your business and individual users. This
customization is accomplished through Telephone Programming.

Automatic Line Selection

When a user lifts the telephone’s handset or presses



Spkr

,

the system chooses
an idle line automatically. Automatic Line Selection determines the order in
which the system looks for an idle line. You can set the system to look for lines
in any desired order. For standard phones or for any phone used mainly to call
other extensions, select an inside (intercom) line first.

Extension Name on Display

With Extension Name Display, users can assign a name (up to 12 characters
long) to their extension. Then, when those users make an intercom call, group
call, or transfer a call, their name and extension number appears on the display
phone receiving the call. Similarly, users receiving a transfer return call see the
name and extension number of the person assigned to the extension that did
not answer the transferred call.

Line Ringing

Line Ringing defines when each outside line rings at a phone. For each line at
an extension, you can specify Immediate Ring, Delayed Ring (phone rings after
a 20-second delay), or No Ring.

Personal Speed Dialing

Personal Speed Dial numbers are outside phone numbers that a user dials by
pressing

 Feature  (or  #  on a standard phone) plus a two-digit code. Unlike

System Speed Dial numbers, which are available to all users in the system,
Personal Speed Dial numbers are available only at the extension for which they
are programmed. Users can store up to 20 Personal Speed Dial numbers.

Programming Telephone Buttons

Telephone buttons without lines assigned to them can be programmed for
system features such as Exclusive Hold or Conference Drop or for telephone
numbers, so you can use the feature or dial the phone number with one touch.
Once programmed, these buttons are called Auto Dial buttons, because simply
pressing the button automatically dials the feature code or the telephone
number.

A user who has a system phone with programmable buttons should consider
programming them with a combination of frequently used features and outside
and intercom telephone numbers.

Programming

2-15

Programming a Receptionist’s Extension
Call Handling Options

If you set up a centralized telephone answering position at extension 10, use the
following settings to customize it:

■

■

■

Immediate Call Answering. If the receptionist should answer all calls,
use Line Assignment (#301) to assign all lines to extension 10. Set Line
Ringing for all lines at extension 10 to Immediate Ring; set the lines

assigned at each user’s extension to Delayed Ring or No Ring.

Backup Call Answering. If the receptionist should answer some lines

only when a user does not pick up, set Line Ringing for those lines at
extension 10 to Delayed Ring; set the lines assigned at each user’s
extension to Immediate Ring.

No Answering. If some lines should not be picked up by the receptionist
at all, either set Line Ringing for those lines at extension 10 to No Ring or
simply use Line Assignment (#301) to remove those lines from extension

10. In either case, set Line Access Restriction (#302) to No Access for
those lines at extension 10 to prevent the receptionist from using Direct
Line Pickup to access those lines.

Button Programming

The MLS-34D phone shown in Figure 2-4 illustrates the following programmed
buttons in addition to some other system features:

■

■

Extension Numbers. Auto Dial buttons are programmed for extensions

11 through 30, starting with the top left button shown in Figure 2-4. The
receptionist can use these buttons to dial or transfer calls to the
extensions with one touch. In addition, the lights of the Auto Dial button
show the status of the extension, so the receptionist can tell whether the
phone at the extension is idle (no lights on), busy (red on), calling the
receptionist (green flash), or ringing back after the receptionist

transferred a call (green flutter).

Fax Management. A button (labeled Fax-31) is programmed as a Fax
Management button for the fax machine connected to extension 31. The
lights next to the button show what is happening at the fax machine (for
example, red broken flutter indicates that the fax machine is not
responding—like when it is out of paper). (For more information, see “Fax
Management Feature” in Chapter 4.)

Alternatively, the receptionist can use an MLS-CA24 Intercom Autodialer for the

extensions the receptionist dials most frequently. This leaves buttons on the
phone free for more features and phone numbers.

Using Telephone Programming

There are two ways to program a telephone: Centralized Telephone
Programming from extension 10 or 11 (see below) and Extension Programming

from a user’s own extension (see page 2-20).

Telephone Models

Figure 2-5 illustrates an MLS-34D, MLS-18D, MLS-12D/MLS-12, and MLS-6
phone. As you program buttons, mark their functions on the phone’s labeling
sheet (see the examples in Figure 2-5).

NOTE:

An MLS-6 phone with 4 lines assigned to it has no buttons available for
programming. The MLC-6 cordless phone looks just like an MLS-6 phone when
you program it centrally.

Using Centralized Telephone Programming

Use Centralized Telephone Programming to program features or store
telephone numbers for individual extensions from extension 10 or 11. Most
features also can be programmed on a system phone at the user’s extension.

Keep in mind the following exceptions:

■

■

■

Automatic Line Selection and Line Ringing always must be

programmed using Centralized Telephone Programming.
If a user has a standard phone, Personal Speed Dial Numbers for the

extension can be programmed only by using Centralized Telephone

Programming.
If a user has a standard phone or a non-display system phone,

Extension Name Display for the extension can be programmed only by
using Centralized Telephone Programming.

Programming

2-17

During Centralized Telephone Programming, the display phone at extension 10
or 11 takes on the characteristics of the telephone being programmed, including
any System Programming settings and lines assigned to the phone. Make sure
the programming phone is as large as the largest phone in the system, because
an MLS-18D phone cannot program an MLS-34D phone and an MLS-12D

phone cannot program an MLS-18D phone or an MLS-34D phone.
To program a phone from extension 10 or 11, use the following procedure:

This chapter explains how system and standard phones work with the system,
as well as combination extensions where more than one phone or standard
device is installed. System phones are described first, followed by standard
phones on page 3-7 and combination extensions on page 3-10. In addition, call
handling features are listed on page 3-11. See the feature name in Chapter 5
for details on a specific feature.

System Telephones

System phones, which include the MLS-34D, MLS-18D, MLS-12D, MLS-12,
MLS-6, and MLC-6 models, have several buttons and indicators in common.
The following pages explain where they are and how they work.

Lights

Each line button has a green light and a red light. The meaning of these lights
varies, depending on whether a button is used to access an outside line, is
programmed with a system feature, or is programmed for Auto Dialing an
extension number (Intercom Auto Dial button). (Auto Dial buttons for fax
extensions show additional information; these “Fax Management” buttons are
described in Chapter 4. When a phone is in programming mode, the lights
show information about programmed settings; See Chapter 2 for details.)

Ringing Patterns

System phones have these ringing patterns:

■ An outside call will ring . . . ring . . . ring.

■ An intercom call will ring BEEP. . . ring BEEP. . . ring BEEP. If you have

a system display phone, the caller’s extension number (and name if

programmed) will show on the display.

■

A transferred call, or an unanswered transferred call that is ringing back
at your extension, will ring BEEP BEEP. . . ring BEEP BEEP. . . ring BEEP

BEEP.

NOTE:

If you use the system with PBX or Centrex lines, the PBX/Centrex distinctive
ringing patterns are not passed to phones. Phones use the ringing patterns
described here instead.

Dial Tones

You will encounter two different dial tones when calling with a system phone:

■

■

Outside dial tone is generated by your local phone company to indicate

that you are connected with an outside line.

Intercom dial tone is generated by the system to indicate that you are

connected with an inside line. You hear this dial tone when you are

making an inside, or intercom, call.

To hear the difference between the two types of dial tones on a system phone,
press a line button. The dial tone you hear is an outside dial tone. To hear an
intercom dial tone, press



Intercom

.

Using the Handset, Speaker, and Microphone

Every system phone (except the MLC-6 phone) has a speaker, which you can
turn on by pressing



Spkr

.

When the green light next to



Spkr



is on, the speaker

is on.
MLS-34D, MLS-18D, MLS-12D, and MLS-12 phones also have a microphone.

On these phones, pressing



Spkr



turns on both the speaker and the
microphone. In addition, you can turn just the microphone on and off by
pressing



Mic

.

When the green light next to



Mic



is on, the microphone is on.

Learning About Telephones

3-5

If you prefer to dial and conduct calls without lifting the handset, you can use
the speaker and the microphone instead. Use these techniques to make calls

with the speaker and the microphone (if you have one):

■

■

■

■

To make a call without lifting the handset, press  Spkr  to get a dial tone;

then dial the number and you will hear the call ringing. When the other

party answers, you can talk without lifting the handset. On MLS-6 phones
(which have no microphone), you must lift the handset to talk when the

other party answers. You cannot listen through the handset and the

phone’s speaker at the same time.
To turn off the microphone when you are using the speaker, press

 Mic .

This will mute your voice so the other party cannot hear you.

If you are already on a call, you can switch from the handset to the

speaker and microphone (on an MLS-34D, MLS-18D, MLS-12D, or

MLS-12 phone) by pressing

 Spkr  and hanging up the handset.

Conversely, if you are using the speaker and microphone and want to
switch to the handset, lift the handset and the speaker and microphone
will turn off.

Use the Hands-Free Answer on Intercom (HFAI) feature to answer

voice-signaled calls without lifting the handset (see below).

Hands-Free Answer on Intercom (HFAI)

When you receive a voice-signaled intercom call, your phone beeps once to
indicate that your speaker has been turned on automatically, and you hear the
caller’s voice over your phone’s speaker. If you leave your microphone on all
the time, you can start talking when you hear the caller, without lifting the
handset. This feature is called Hands-Free Answer on Intercom.

NOTE:

Since MLS-6 phones do not have microphones, you must lift the handset to
answer voice-signaled calls to those phones.

Any user in the system can make a voice-signaled call to an idle MLS-model

system phone by pressing



Intercom

  ✳ 

and then dialing an extension number

or pressing an Auto Dial button programmed for voice signaling. (You can

make a voice-signaled call from either a system phone or a standard phone.
However, if you try to make a voice-signaled call to a standard phone or MLC-6
phone, it will ring.)

NOTES:

1.

The HFAI feature can be turned on or off only when your phone is idle. Muting
your voice while you are on a call only turns off the microphone for the duration
of the call.

2. If HFAI is on and you are already on a call, you will not hear any other voice
signals to your extension.

3.

If you make a voice-signaled intercom call to a busy extension, you may
initiate a voice interrupt on busy call to that extension. See “Voice Interrupt On
Busy Calls” on the next page for more information.

3-6

Learning About Telephones

Voice Interrupt on Busy Calls

A voice interrupt on busy call is a special intercom call that lets you interrupt

and speak to another user who is busy on a call and who has the Voice
Interrupt On Busy feature (#312) activated for that user’s phone. When you
use Voice Interrupt on Busy to interrupt another user on a call, the interrupted
user hears two beeps before hearing your voice. Be aware that the third party

to whom the interrupted user is speaking will probably hear the two beeps and
the faint sound of your voice. Therefore, the message you deliver with the

interruption should be brief and discreet. If the interrupted user wants to answer

you, he or she can press a programmed Talk-Back button—the interrupted

user’s response cannot be heard by the third party in this case.

Speakerphone Performance Tips

The speaker on your MLS-34D, MLS-18D, MLS-12D, or MLS-12 telephone has a
sensitive sound-activated switch. Room acoustics and background noise can
affect the proper operation of the speakerphone. To ensure that your
speakerphone works effectively, follow these guidelines:

■

■

■

■

■

■

■

■

Avoid placing your phone in areas with high background noise caused by
loud voices, radios, printers, copiers, typewriters, other noisy office
equipment, and heater and air conditioning fans.

Avoid rustling papers near the microphone (lower right corner of your
phone).

Avoid talking before the other person is finished speaking. When you
both talk at the same time, only one person’s voice comes through.

Do not use your speaker to make announcements over a loudspeaker
paging system connected to your phone system.

When talking, always face your phone and stay within two feet of it.
Place your phone at least six inches away from the edge of your desk.
If you have difficulty hearing the other party, try increasing the speaker

volume. If you have background noise, try turning off the microphone
when the party at the other end is speaking and turning it on when you
speak. If the difficulty persists, lift your handset to continue the
conversation.

In conference rooms, a separate speakerphone (such as the AT&T S203

Speakerphone) is recommended, since the built-in speaker on a system
phone is designed for individual use.

Standard Telephones

In addition to system phones, you can connect industry-standard touch-tone or

rotary dial phones—and even some feature phones (which have built-in calling
features)—directly to the system. You can also combine standard phones on
the same extension with system phones or other devices, without using

expensive adapters or connectors.

Learning About Telephones

3-7

Standard phones can do many of the things that system phones can do, and
you can save money by using them in certain situations when a system
telephone is not needed. Follow these guidelines when using standard phones:

■

■

■

■

■

Use standard phones as power failure backups. In the event of a power

failure, standard phones at extensions 10, 16, 22, and 28 connect to lines

1, 3, 5, and 7, respectively, for continued operation; but system phones
will not work. You can connect standard phones in combination with
system phones at power failure extensions, or you can simply keep spare
standard phones at those extensions to serve as replacements in case of
a power failure.

To use a system feature, press

 # 

(in place of



Feature



used on system

phones) followed by its two-digit code when you hear intercom dial tone.
For features that use

 Intercom  on system phones, dial only the two-digit

code when you hear intercom dial tone. (Instructions for using these
features on standard phones are included in Chapter 5, “Feature
Reference.”)

To use a Speed Dial number, press

 #  followed by its two-digit code

when you hear intercom dial tone. (For details, see “System Speed Dial
Numbers” and “Personal Speed Dial Numbers” in Chapter 5.)

Use the switchhook on a standard phone to place calls on hold, transfer a
call, or set up a conference call. (For details, see “Using the Switchhook”
on the next page, or “Hold,” “Transferring Calls,” and “Conference Calls”
in Chapter 5.)

If the standard phone has a message waiting light, use it to notify users of
messages. (For details, see “Message Light On” and “Message Light
Off” in Chapter 5. For a list of supported phones, see “Standard
Telephones” in Chapter 1.) Alternatively, if you have a voice messaging
system, the light is used to indicate that a message has been left in your
mailbox. On a standard phone, the message light flashes when the

phone is idle to indicate that the extension has received a message.

Ringing Patterns

Standard phones have these ringing patterns:

■ An outside call will ring . . . ring . . . ring.

■ An intercom call will ring-ring . . . ring-ring . . . ring-ring.

■ A transferred call, or an unanswered transferred call that is ringing back,

will ring-ring-ring . . . ring-ring-ring . . . ring-ring-ring.

NOTE:

If you use the system with PBX or Centrex lines, the PBX/Centrex distinctive
ringing patterns are not passed to phones. Telephones use the ringing patterns
described here instead.

3-8 Learning About Telephones

Dial Tones

Standard phones have two different dial tones:

■

■

Outside dial tone is generated by your local telephone company to

indicate that you are connected with an outside line.

Intercom dial tone is generated by the system to indicate that you are

connected with an inside line. You hear this dial tone when you are

making an inside, or intercom, call.

To hear the difference between the two dial tones, lift the handset. The dial tone
you hear (assuming the phone is set to select intercom first, as recommended in
this guide) is an intercom dial tone. To hear an outside dial tone, press

 9 .

Using the Switchhook

Some of the call handling instructions in this guide direct you to “rapidly press
and release the switchhook.” Pressing the switchhook for 1/4 to 1 second sends
a signal over the line called a switchhook flash. However, do not press the

switchhook too quickly. If you press the switchhook and nothing happens, try

again and press it a little longer.

NOTE:

If your feature phone has a button labeled “Recall” or “Flash,” use the button
instead of pressing the switchhook. If you use the system with PBX or Centrex
lines, your PBX or Centrex documentation may tell you to press the switchhook

to access PBX or Centrex features. Use the Recall feature instead (see “Recall”

in Chapter 5).

Limitations

Because standard phones do not have system line buttons, feature buttons, or
dedicated function buttons, basic call handling procedures are sometimes
different from those for system telephones. In addition, the following actions

cannot be performed at a standard telephone:

■

■

■

■

■

You cannot enter programming mode.

Because there are no line buttons on standard phones, users must use
Direct Line Pickup—idle Line to select a specific line; otherwise, the
system selects an idle line automatically when the user dials a 9 at
intercom dial tone. (For information on Automatic Line Selection, see
Chapter 5.)

If a standard phone is in use, there is no indication of a second call and
an inside caller will hear a busy tone.

Users can make a voice-signaled call from a standard phone, but if users
try to make a voice-signaled call to a standard phone, it will ring because
the standard phone does not have a system speaker.

Users cannot use the

System Password.

Learning About Telephones

3-9

■

■

Users cannot access the following system features: Account Code
Entry, Background Music, Do Not Disturb, Exclusive Hold, Privacy,
Save Number Redial, VMS Cover, Voice Interrupt on Busy, Voice
Interrupt on Busy Talk-Back, and Voice Mailbox Transfer.

Do not use Forced Account Code Entry with a standard phone,
because the phone will bot be able to get dial tone and make calls.

Feature Phones

A feature phone is a standard telephone that has feature buttons in addition to
the regular 12-key dial pad. For example, there are feature phones that have
programmable auto dial buttons, last number redial buttons, hold buttons, and
built-in speakers. Even though some feature phones have buttons like those
provided on system phones, they may not work. Refer to the feature phone’s
documentation for more information on what these phones can do.

Combination Extensions

A combination extension is an extension with two devices connected to
it—either two standard devices, or a system phone and a standard device (but
not two system phones). (For instructions on how to install a combination
extension, see the PARTNER Plus Communications System Installation guide.)

The following are examples of useful combination extensions:

■ System phone plus standard telephone, for power failure backup on

extensions 10, 16, 22, and 28

■

System phone plus answering machine

■

System phone plus fax machine

■

System phone plus headset

■

System phone plus an external alert (such as a bell or chime).

Using the telephones in a combination extension is fairly simple. The main thing
to understand is that the two telephones share a single extension in the same
way several home telephones share a single line. A system telephone works
like it always does and a standard telephone works like it always does when
connected to the system. Only one phone or device can be used at a time,
unless you want to join the two on a single call (the same way two people can
pick up the same call on different telephones at home). For example:

■

■

■

■

■

Both phones share the same extension number.
Both phones share the same voicepath, that is, when either phone is

busy, the extension is busy.

Calls ring at both phones.

A second call can ring at the system phone while the standard phone is
busy, but do not use the system phone to answer the second call until the

standard phone is idle or the first call will be disconnected.
If you make a voice-signaled intercom call to a combination extension

with a system phone, only the system phone signals.

3-10

Learning About Telephones

■

■

■

■

■

The lights on the system phone show what the standard telephone is
doing as well as what the system phone is doing. For an explanation of
light patterns, see “Lights” at the beginning of this chapter.

If Privacy is active at a combination extension, no other extension can
join a call in progress at either a system phone or a standard device.
(However, a phone can interrupt a call on a standard device at the same
extension. For example, if a system phone and modem are combined at
an extension, picking up the handset of the system phone could interrupt

a modem transmission, even if Privacy is active.)

While on a call on a standard phone, you can use the system phone’s
dial-pad and fixed-feature buttons to handle calls. For example, you can

use the system phone to select a specific outside line, and conduct the
call on the standard phone. Or, if someone is on a call using the
standard phone, someone else can put that call on hold by pressing

 Hold  on the system phone. To do this, it is not necessary to lift the

handset of the system phone. Held calls do not ring at a standard phone
in a combination extension. To retrieve a held call from the standard
phone, use Direct Line Pickup—Active Line.

A standard phone’s message waiting light will not light if Background

Music is playing through the system phone’s speaker.

The ringer equivalence number (REN) of a standard device or the

combined REN of two devices cannot be greater than 2.0. (The REN of a
system phone is 0.0.)

Using Telephones

Your system provides intuitive operation of basic call handling features, plus
dial-code features that make it easy for users to handle calls flexibly and
efficiently from both system and standard phones. For more information on a
specific feature, refer to the feature name in Chapter 5.

Basic Call Handling Features

The following features are available from both system and standard phones:

■

Making Calls

■ Answering Calls

■

Hold (placing a call on hold)

■

Transferring Calls (passing a call to another system extension)

■ Conference Calls (making a conference call)

Overview

There are many ways to set up auxiliary equipment—the setup you choose
depends upon your needs and the number of devices you have. This chapter
presents some common setups. (It does not cover how to physically connect
the equipment, or how to program the features. See the PARTNER Plus
Communications System Installation guide for installation instructions, Chapter 5
for programming instructions, and the equipment manufacturer’s documentation
for complete details on the device you connect.)

This chapter shows various applications for the following types of equipment:

Doorphones allow visitors to signal extensions by pressing a button on
the doorphone; the person who answers a doorphone call can then
speak with the visitor at the doorphone. A doorphone is especially useful
for providing access to offices or departments after hours. For example,
you can install a doorphone outside your building entrance to allow
visitors to ring telephones inside the building when the receptionist is not
there and the front door is locked.

The system supports up to two AT&T PARTNER Doorphones or any
number of AT&T Universal Doorphones. Universal Doorphones offer a
door unlock feature and can be installed in addition to PARTNER
Doorphones.

Loudspeaker paging systems allow you to broadcast a message over a
large area, by connecting the paging system directly to the PAGE jack on
the processor module. The system supports all AT&T paging systems
including the entire PagePac® line, and most paging systems from other
manufacturers. In addition to its numerous paging features, the
PARTNER PagePac provides doorspeaker and door unlock capabilities.
For information on how to use a loudspeaker paging system with the
system, see Chapter 5.

PARTNER Passage Way™ Solution

allows you to combine your
Personal Computer (PC) running Microsoft® Windows™ 3.1 with your
phone. You can then use your PC for tasks such as dialing out from an
electronic phone list, logging phone calls, and programming your phone.

Music-on-hold systems allow you to play recorded music or messages
to callers while they are on hold, by connecting the audio source to the
processor module. The system supports the AT&T Magic on Hold system
and most models from other manufacturers. (If you use equipment that
rebroadcasts music or other copyrighted materials, you may be required
to obtain a license from a third party such as ASCAP or BMI.)

Extra alerts help make users aware of incoming calls. For example, you
can use an audible alert (chime, horn, or bell) to replace a phone ring in a
noisy area, such as a factory. Similarly, you can use a visual alert (strobe
or light) to replace a phone ring in a quiet area, such as a library. AT&T
offers several compatible alerts.

Speakerphones provide hands-free two-way operation of a phone
without lifting the handset. Combining a speakerphone with a system
phone or a standard phone in a conference room or office is an
inexpensive way for several people at a meeting to conference in other
parties. (System phone speakers are designed for individual use—not
group use.) The system supports the AT&T S203 speakerphone and any
industry-standard speakerphone.

Headsets allow users to hold hands-free conversations. A headset is a
combination earphone and microphone worn on the head, useful for
receptionists, salespeople, or others who need to have their hands free
while talking on the phone. AT&T offers several compatible headsets.

Specialty Handsets are designed for those individuals who need greater
functionality than that provided by the handsets on system phones and
standard phones. For example, an amplified handset is available for
certain system phones for hard-of-hearing users.

In-Range Out-of-Building (IROB) protectors are required to prevent
electrical surges from damaging your system when phones are installed
in another building, but on the same continuous property. The system
supports the AT&T IROB protector, which provides coverage for up to
3,000 feet (915 meters) for standard phones and 1,000 feet (305 meters)
for system phones.

Electromagnetic Interference (EMI) filters allow you to block “noise”
generated by a nearby radio station, as well as most electrical devices.

Caller ID devices, such as a PC with Caller ID software, support
applications for storing or processing Caller ID information. You can
connect these devices provided you subscribe to the service from your

local phone company and connect the device directly to the Caller ID
line. To install devices, refer to “Connecting Caller ID Devices” in the
PARTNER Plus Communications System Installation guide for details.

Follow the manufacturer’s instructions packaged with the devices. To order
auxiliary equipment, refer to “Product Ordering Information” in Appendix B.

If a Device Has Trouble

Two System Programming procedures can be used to adjust the system
settings for auxiliary equipment installed at an extension, if a device has trouble
answering calls or dialing out. If a device (such as an answering machine) does
not pick up transferred or intercom calls, you can use Distinctive Ring (#308) to
change the ringing, so that all calls ring like outside calls at that extension. If an
autodialing device (such as a modem) has trouble autodialing, use Intercom
Dial Tone (#309) to change the intercom dial tone for the extension to Machine
(outside line) dial tone.

Using Auxiliary Equipment

4-3

Answering Machines

You can use an answering machine to answer calls at night when no one is
around, or during business hours when no one can get to the phone. If you
have an AT&T answering machine with the Call Intercept feature, you can pick
up a call that has been answered by the answering machine by joining the call
from any system phone. When you do so, the system sends the answering
machine a signal that makes it hang up.

The following are ways you can connect answering machines to your system:

■

■

■

Single answering machine. This basic setup can cover all the lines in

the system. Anyone on the system can call the machine to retrieve
messages.

Multiple answering machines. If you get too many calls for one
machine to cover, connect two or more machines to cover all calls.

Personal answering machine. An answering machine can share an

extension with a phone to answer calls to the extension.

NOTE:

If you have an answering machine and a system phone on the same extension,
the answering machine will be able to answer calls only when the phone is idle.

4-4

Using Auxiliary Equipment

Single Answering Machine

The single answering machine setup (Figure 4-1) serves the entire system. The
answering machine is connected to its own extension, and can cover all the
lines in the system, or as many lines as you assign to it. You can install the
answering machine on an extension by itself, or combine it with a system phone
or a standard phone on the same extension (see “Combination Extensions” in
the PARTNER Plus Communications System Installation guide).

Adjust the answering machine to answer according to your needs. For

example, set the machine to answer on the fourth ring during the day so
someone has a chance to pick up the call.

Multiple Answering Machines

If a single answering machine cannot handle all your calls, you can set up two
or more machines at different extensions (Figure 4-2) so that a call does not go
unanswered. If one answering machine is busy, a second call will be answered
by the second machine. A setup such as this might be used by a movie theater
to announce movie times to people calling for information.

Call Reporting Devices (SMDR)

SMDR (Station Message Detail Recording) is a call reporting feature that
provides records of call activity. Call reporting information provides you with the

ability to:

■

■

■

■

Detect any unauthorized calls
Bill clients or projects
Bill back by departments

Reduce telephone costs by identifying the need to change
telecommunications services (like adding a WATS line for calls to a
particular area code)

Call reporting information is recorded after each call is completed. The system

records information for each call that lasts at least 10 seconds. For outgoing

calls, the timing begins when you get dial tone. For incoming calls, the timing

begins when you answer the call. Timing stops when the call is disconnected.

The system sends the information through a 1200-baud serial interface to either

a serial printer or a call accounting device. The device connects directly to the

SMDR jack on the processor module.

Programming

Use the following programming procedures for call reporting:

■

■

■

■

SMDR Record Type (#608) to specify the type of calls that you want to
record for call reporting—either all calls or outgoing calls only.

SMDR Top of Page (#609) to notify the system that the printer has been
aligned to the top of a new page.

Forced Account Code Entry (#307) to identify extensions that are
required to enter an account code prior to making outside calls and

Forced Account Code List (#409) to create a list of valid account codes.
Display Language (#303) to specify the language to be used for display

messages. The call report header is printed in the same language as is
specified for extension 10.

Sample Call Report

Each page includes 59 records. The report has the following fields:

■

■

■

■

■

■

■

■

Call Type. “C” indicates outgoing calls; “I” indicates incoming calls.

(SMDR Record Type (#608) defines whether or not incoming calls are
reported.)

Date. The date of the call is shown in mm/dd/yy format, where mm is the
month, dd is the day, and yy is the year. The system uses the date set
with System Date (#101).

Time. The time of the connection is shown in hh:mm format, where hh is
the hour and mm is the minute. The system uses the time set with
System Time (#103) and is shown in 24-hour (military) time.

Number. For an outgoing call, this is the dialed number (first 15 digits

only) or the speed dial code of a Marked System Speed Dial number
(preceded by an “F”). For an incoming call, “IN” appears in this field.

A “*” character prints as the last digit of a dialed number if the called
party hangs up before the system user, or a “?” prints if the number of

digits dialed exceeds the 15 digits that this field can hold.
Duration. The duration of the call is shown in hh:mm:ss format, where hh

is the hour, mm is the minutes, and ss is the seconds. This is the total
time of the call, including any time the call is on hold.

Line Number. This is the outside line (01–12) that was used to make or
receive the call.

Station (Extension). In general, this is the extension that answered or
placed the call. For redirected incoming calls, the last extension on the

call is shown on the report, as follows:
– For transferred incoming calls: the destination extension.
–

For transferred outgoing calls: the originator extension.

–

For pickup calls: the extension picking up the call.

–

For forwarded calls: the extension answering the forwarded call.

Account Code. This is the account code (up to 16 digits) assigned to

the call. This code is typically used for charging calls to a specific

project or department.

Considerations

■

■

■

■

■

■

The System Date (#101) and System Time (#103) must be set correctly
to ensure accurate call reports.

If a report cannot print because the printer is jammed or out of paper, the

system will store up to 45 records in its memory until they can be printed.

Additional calls will not be recorded.
In the event of a power failure, records of any calls in progress are lost.
Inside (intercom) calls are not recorded.
If you place a call on hold and the caller hangs up, the call is considered

complete and the record is sent to the call reporting device.
Conference calls appear as two outside calls. (This means two records

are generated on the report.)

Output Format

The following serial transmission protocol is used for SMDR records:

■

1200 baud

■

no parity

■

8 data bits

■

2 stop bits

The call reporting feature also supports XON/XOFF protocol, carriage returns,

and line feeds.

Serial Printers

Use a 355A adapter, which converts a modular jack interface to an RS-232
25-pin connector, to connect a serial printer to the processor module. If you
connect a printer, make sure the printer can receive SMDR data in the format
described above (refer to the printer’s instructions if you need help).

Call Accounting Devices

You can send call information to a call accounting device (such as AT&T’s Call
Accounting Terminal—Basic or Plus) if you want to further analyze call activity.
The device stores rate table information and processes the information it

receives into meaningful reports that can help you optimize your
communications system. For example, you can use it to determine the best
combination of local and long distance lines for your business.

The call accounting device connects directly to the SMDR jack on the processor

module and can also print out reports that include summaries by hour, line, and
extension. Refer to the manual provided with the call accounting device for
instructions on connecting it to your system.

Using Auxiliary Equipment

Credit Card Scanners

Many retail businesses and restaurants use credit card scanners to get instant
approval of credit card purchases. The system allows your credit card
scanners to share the lines in your system (as shown in Figure 4-5). You can
install the credit card scanner on an extension by itself, or combine it with a
system phone or a standard phone on the same extension (see “Combination
Extensions” in the PARTNER Plus Communications System Installation guide).

Fax Machines

This section suggests several ways you can set up fax machines to work with

your system. It includes instructions for programming and using a Fax

Management button on a system phone (in order to monitor the status of a fax
machine and transfer calls to it with a single touch), transferring calls to the fax
machine extension, and using an AT&T fax machine’s Notify feature.

Using Fax Machines
Fax Management Feature

On any system phone, you can program a button with lights to serve as a Fax

Management button. The lights next to this button tell you when the fax machine

is in use, available, or not answering (for example, when it is out of paper). You

can also use the button to transfer calls from your extension to the fax machine
with a single touch.

Programming for Fax Management

To program a Fax Management button, first assign the fax machine extension

using Fax Machine Extensions (#601). (See Chapter 5 for details.) Then

program the fax machine extension number on an Auto Dial button. For more

information, see “Auto Dialing” in Chapter 5.

Using the Fax Management Button

The lights next to the Fax Management button show what is happening at the fax

machine—see Table 4-1.

Table 4-1. Fax Management Button Light Patterns

Green flutter

Fax transfer return. A call you transferred to
the fax machine was not answered and is
returning to you.

4-12

Using Auxiliary Equipment

Transferring a Call to the Fax Machine

There are two situations in which you would want to transfer a call to your fax
machine:

■ You answer an outside call and hear a fax machine signaling. (A fax

signal is a single beep sequence— beep . . . . beep . . . . beep). If you

hear this, you should transfer the call immediately to the fax machine

extension.

■

You are on a call with a person who wants to send you a fax using the fax

machine that is connected to his or her phone. You can receive the fax

by transferring the call to your fax extension. Tell the other party to wait
until he or she hears the fax signal before pressing the Start button on

their fax machine.

In addition, if you have a PARTNER MAIL system and a fax call comes in on a
line covered by the PARTNER MAIL system, its Automated Attendant Service
can be programmed to automatically transfer the call to a fax extension or (if you
have multiple fax machines) to the extension Hunt Group for the fax machines.

There are four ways to transfer the call to the fax extension:

■

■

■

■

If you have a Fax Management button, simply press the button. When the
fax machine answers, hang up.

If you do not have a Fax Management button, press

 Transfer  plus the fax

machine’s extension number. When the fax machine answers, hang up.
On a standard phone, rapidly press and release the switchhook to place

the call on hold, then dial the fax extension number and hang up.

When a fax machine answers, hang up.

Using the Fax Machine’s Notify Feature

Some AT&T fax machines (for example, models 5300, 5350, 9025 Plus, and
9035 Plus) have a feature called Notify. After such a machine receives a fax
call, it automatically dials a number and plays a recorded message, such as,
“You have just received a fax.” If you need to know exactly when a fax comes
in, or if your fax machine is located in an isolated part of your building, you can
use Notify in any of the following ways:

■

Program the fax machine to make a ringing or voice-signaled intercom
call to an individual extension or to a group. (Program the fax machine to
dial

 ✴ 

plus the extension number for a voice-signaled call;

 7 

and a

extension by dialing

 #   0   9 

plus the extension number.

■

Program the fax machine to dial

 7   0 

to make its recorded

announcement over your loudspeaker paging system.

Using Auxiliary Equipment

4-13

For all of these examples, program the fax machine extension’s Automatic Line

Selection to select intercom first, followed by whatever outside lines you want to

assign to it. (If you set the fax extension to select intercom first and the machine

has an auto dial feature, program a 9 and a few pauses before each Auto Dial

number. When manually making a call, dial

 9  to get an outside line. For

instructions on how to set the Automatic Line Selection, see Chapter 5.)

Setting Up Fax Machines

There are many ways to set up fax machines. The following configurations are
basic and easy to use:

■

■

■

Single fax machine. Good for light or moderate fax traffic. This basic
setup uses a published fax number.

Fax machine line saver. Good for light fax traffic, with no need for a
published fax number.

Send and receive fax machines. Good for high-volume fax traffic. One

machine sends, the other receives.

You can install both a telephone and a fax machine on the same extension—see
“Combination Extensions” in the PARTNER Plus Communications System
Installation guide. This lets you receive both voice and fax calls on the same
line (but not at the same time). If you pick up the phone and hear a fax signal,
push the Start button on your fax machine and then hang up.

If you are using the PARTNER MAIL system’s Automated Attendant Service, you
can program PARTNER MAIL to transfer fax calls to the fax extension or a group
of fax extensions automatically. Use Fax Machine Extensions (#601) to identify
fax extensions. If you have multiple fax machines, put all of the fax extensions
into a single Hunt Group (any of groups 1–6) using Hunt Group Extensions

(#505).

Restricting Dialing from a Fax Machine

You can use dialing restrictions to restrict calling activity on a fax machine. For
example, you can use Outgoing Call Restriction (#401) to restrict the fax

restrictions, see Chapter 2.

Send and Receive Fax Machines

If your business has high-volume fax traffic, you can set up two fax machines,
one that only sends and the other that only receives. For example, in Figure 4-8,
fax 1 is the send machine, fax 2 is the receive machine. Line A is the fax line,
the number of which is published as the fax number. If fax 2 doesn’t answer line
A, fax 1 will.

Send and Receive Fax Machines

To Use

When you send a fax, an outside line will be automatically selected. Incoming
fax calls on the fax line are answered automatically by fax 2. If a fax comes in
on a line other than line A, you can transfer the call to fax 2 (see “Transferring a
Call to the Fax Machine” earlier in this chapter). If you have programmed a Fax
Management button, you can transfer a call to the fax machine with a single
touch, as well as monitor the status of the fax machine (see “Fax Management
Feature” earlier in this chapter). If fax 1 is set for Delayed Ring on line A, fax 1
can pick up fax transmissions when fax 2 does not answer.

To Program Fax 1 (Send—Ext. X)

1.

Set Automatic Line Selection for extension X to select outside lines first (line
A selected last).

2.

Set Line Ringing for line A at extension X to Delayed Ring; set all other lines
to No Ring.

Using Auxiliary Equipment

Modems

There are several ways to use modems with your system, as described below.

NOTE:

Modems can connect directly to an extension jack without an adapter.
However, if you connect a high-speed modem through the control unit, you may
experience some degradation of efficiency and throughput, depending on the
quality of the central office lines connected to the system. To solve the problem,
either connect modems directly to the network interface jacks, or contact your
local telephone company for information about upgrading line quality.

Stand-Alone Modem for Placing Calls Only

A modem and a terminal allow you to dial out and connect to computer bulletin

boards and other data services. This setup, which lets you dial out but not
receive calls, is shown in Figure 4-9. Note that the telephone is optional and

can be used if you want the terminal to share an extension with a phone.

Using Auxiliary Equipment

Night Service with Auxiliary Equipment

You can set up modems, fax machines, and answering machines to receive
calls automatically after hours. When Night Service is on, calls ring immediately
at the appropriate extensions, so that no human intervention is required to
transfer calls to the fax, modem, or answering machine. When Night Service is
off, you can use the auxiliary equipment lines for normal business purposes, so
that lines are dedicated to auxiliary equipment only after hours.

By putting auxiliary equipment in the Night Service Group as described in this
section, auxiliary equipment can start ringing and answering calls whenever you
turn Night Service on. In other words, the Night Service button at extension 10
acts like a switch, turning auxiliary equipment on and off, as well as putting the
system into Night Service.

NOTE:

If you have a voice messaging system, turning Night Service on also activates
Night Service operation of the voice messaging system.

Figure 4-11 shows a system with a fax machine and a modem connected to
separate extensions. Line A is published as the fax line, and line B is published
as the modem line.

To Use

During the day, lines A and B do not ring at extensions X and Y. When you turn
Night Service on, calls on line A ring immediately at the fax (extension X). Since
that line is not assigned to any other extension in the Night Service Group, only
extension X receives fax transmissions. Likewise, with Night Service on, calls on
line B ring immediately at the modem (extension Y). All lines ring at the system
phone at extension Z.

Using Auxiliary Equipment

NOTE:

If answering machines are connected to Night Service extensions, you can join
a call that was already answered by an answering machine from any system
phone. If you have an AT&T answering machine with the Call Intercept feature,
the answering machine drops off the call when you join it.

lines to extension Z.

Make sure extensions X and Y are not assigned as Pickup Group Extensions

Using Auxiliary Equipment

PARTNER Attendant

The PARTNER Attendant answers calls and directs them to a specified
extension or to a Hunt Group (based on the digits a caller dials after listening to
a list of choices in a recorded greeting). For example, the PARTNER Attendant
could answer calls and tell callers to press 1 for Sales, 2 for Parts, 3 for Service,
and so on. The PARTNER Attendant can be set up for immediate call handling
or delayed call handling.

Backup for Receptionist

A common use of PARTNER Attendant is as a backup for the receptionist. If the
receptionist cannot pick up a call within a specified number of rings, PARTNER
Attendant handles it. This prevents calls from going unanswered. Figure 4-12
shows how the PARTNER Attendant would be connected to your system.

When callers call the main number for your company, the receptionist normally
picks up the call. If the receptionist is busy, the PARTNER Attendant answers

and plays a recorded message, such as: “Please hold for the receptionist or

dial an extension number now.”

To Program

Voice Messaging Systems

Two voice messaging systems are compatible with your system. You can install
one or the other, depending on your business needs:

■

The PARTNER MAIL VS Voice Messaging System, which physically
resembles a 206 module, resides in the control unit and provides voice
messaging capabilities for up to 10 subscribers. An optional Mailbox
Expansion Card can extend service for up to 20 subscribers.

■ The PARTNER MAIL Voice Messaging System is an auxiliary device

that connects to the system through extension jacks. It is available in a
2-port or 4-port configuration, providing service for up to 20 or 40
subscribers, respectively.

Both voice messaging systems offer your business complete call processing
features. Specifically, they can:

■

■

■

■

Insure that incoming calls are answered and directed to destination
extensions correctly and efficiently, using immediate or delayed call
handling. (Immediate call handling sends calls directly to the voice
messaging system, while delayed call handling allows the receptionist to
answer calls first.)

Answer and route calls during the day and after normal business hours.
Alleviate the problem of inaccurate or incomplete messages by allowing

callers to leave detailed, confidential messages for subscribers.
Allows subscribers to assign a password to their mailbox, change their

personal greeting, and retrieve messages.

The PARTNER MAIL system also offers advanced voice mail features, such as
outcalling, group lists, broadcast messages, and fax management. You can
refer to the documentation provided with your voice messaging system for
complete details.

Delayed Call Handling

Figure 4-13 shows a PARTNER MAIL VS system that provides delayed call
handling. This setup allows the receptionist at extension 10 to provide
personalized service by answering calls during the day. The PARTNER
MAIL VS system (connected to extensions Z1 and Z2) is used to handle calls
when the receptionist is busy or not available, so calls do not go unanswered.
The PARTNER MAIL VS system also answers calls received after business
hours and prompts callers to leave a message in the receptionist’s mailbox.

This example also includes two user extensions (X and Y), which are not
automatically covered by the PARTNER MAIL VS system. This allows the
receptionist to give the caller more personalized service; if the receptionist
transfers a call to extension X or Y and that extension does not answer, the call
returns to the receptionist. The receptionist can then take a message or send
the call to the extension’s mailbox if the caller prefers.

Figure 4-13. Delayed Call Handling

To Use

Follow the instructions packaged with the PARTNER MAIL VS system to install it.
During the day, the PARTNER MAIL VS system uses delayed call handling; the

receptionist picks up all calls at extension 10. If the receptionist cannot answer
within four rings, the system routes the call to the PARTNER MAIL VS system
where the day menu plays to the caller. At night (when Night Service is
activated at extension 10), outside calls are answered directly by the PARTNER
MAIL VS system. Any user who is still in the office can pick up calls before the
PARTNER MAIL VS system answers.

To Program

The following list summarizes the PARTNER Plus system programming
procedures you use to implement the previous example:

1.

Use Group Call Distribution (#206) to assign outside lines to Hunt Group 7
(the VMS hunt group) to provide Automated Attendant Service on these
lines.

2.

Use Transfer Return Extension (#306) for extensions Z1 and Z2 to ensure
that calls transferred by the PARTNER MAIL VS system return to extension
10 if they are not answered.

3.

Use Hunt Group Extensions (#505) to assign extensions Z1 and Z2 to Hunt
Group 7 (the VMS hunt group).

4.

Set the VMS Hunt Delay (#506) to Delayed.

5.

Set the VMS Hunt Schedule (#507) to Always.

6.

Make sure that a Night Service Button (#503) is assigned at extension
10—the receptionist’s extension. When Night Service is on, callers hear
the night menu when no one is available to answer their calls.

7.

Program a Voice Mailbox Transfer button at extension 10 to enable the
receptionist to transfer calls directly to extension X’s and Y’s mailboxes
without first ringing their phones. (This is useful when the receptionist
knows that the users at extensions X and Y are away from their desk.)

8.

Program an Auto Dial button for the VMS hunt group

Overview

This chapter provides reference information for programming and using system
features. Features are listed in alphabetical order. System Programming
procedures include the procedure code (# and three-digit number) in the
heading; dial-code features include the feature code (F for

 Feature  or I for

which you are most comfortable.

■

For Telephone Programming, this chapter provides only the instructions
for Centralized Telephone Programming. To program from individual
extensions, users should refer to their Quick Reference cards.

All of the instructions in this chapter assume that system phones select outside
lines first and standard phones select intercom first (as determined by each
extension’s setting for Automatic Line Selection).

See Chapter 2 for a review of the methods and buttons you can use while in
programming mode.

AA Extensions (#607)

Description

This System Programming procedure identifies extensions where PARTNER
Attendants are connected to the system. Doing so lets the system notify users
with display phones when they are receiving a call that has been transferred
from the PARTNER Attendant. (This procedure applies only to PARTNER
Attendants—do not use it with the Automated Attendant Service of a voice
messaging system.)

Abbreviated Ringing (#305)

Description

This System Programming procedure turns Abbreviated Ringing on or off at a
specific extension. When a user is on a call and Abbreviated Ringing is on, any
incoming call rings only once. The green light next to the line button flashes
until the call is answered or the caller hangs up (or for a transferred call, until it
returns to the transfer return extension). This feature prevents incoming calls
from distracting users when they are busy on another call. To allow calls to ring
repeatedly, set Abbreviated Ringing to Not Active.

Considerations

■

■

■

■

■

Receptionists, and others who handle many calls quickly, often leave

Abbreviated Ringing off, so they have an audible reminder of incoming calls.

Abbreviated Ringing works for both outside calls and intercom calls.
The volume of an abbreviated ring is lower than a normal ring.
Calls to a busy extension ring at a lower volume than normal even if

Abbreviated Ring is set to Not Active.

Account Code Entry (F12)

Description

Related Features

This feature lets a user with a system phone enter an account code (up to 16

digits) for an outside call (incoming or outgoing). An account code is typically
used to identify a department, project, or client for charge-back or tracking
purposes.

■

■

■

You can use Forced Account Code Entry (#307) to identify extensions that
are required enter an account code prior to dialing any outside number
(including those on the Emergency Phone Number List). A forced account
code must be entered at the beginning of a call; however, a different
account code can be entered any time during the call. (Use Forced
Account Code Entry only for extensions with system phones.)

You can use Forced Account Code List (#409) to create a list of valid
account codes, which should be distributed to the appropriate users. If a
Forced Account Code List exists, the system checks the list whenever a
user enters a forced account code. If a forced account code is valid, the
system provides the user access to an outside line. If a forced account
code is invalid, the system denies the user access to an outside line—to dial
out, the user must repeat the procedure for entering a forced account code.

For faster entry of frequently-used account codes, you can program an
account code on an Auto Dial button or as a System or Personal Speed Dial
number (but not as a Marked System Speed Dial number). See Auto

Dialing, System Speed Dial Numbers, and Personal Speed Dial
Numbers for programming instructions.

Considerations

■

■

■

■

When an account code is entered during a call, the caller on the other end
does not hear the touch-tone digits dialed.

If SMDR is used, the account code assigned to incoming or outgoing calls
prints on call reports. (See “Call Reporting Devices (SMDR)” in Chapter 4
for more information on call reporting.)

If an account code is entered for an outgoing call and the call is transferred
to another extension, the call report shows the originating extension as the
owner of the call. Conversely, if an account code is entered for an incoming
call and the call is transferred to another extension, the call report shows the
destination extension as the owner of the call.

Account codes can be changed during a call. However, only the person
who entered the original account code can enter a different account code.
SMDR prints changed account codes as follows:

–

For optional or forced account code entry without a Forced Account

Code List, the call report prints the last account code entered.

–

For forced account code entry with a Forced Account Code List, the
call report prints the last valid account code entered. If the changed
account code is not valid, the report prints the original account code.

digits supported.

You can program the Account Code Entry feature code on a button on a

Allowed Phone Number Lists (#407)

Description

This System Programming procedure specifies telephone numbers that users
can dial regardless of other dialing restrictions, as long as they have access to
an outside line. For example, if you restrict an entire category of calls through
Disallowed Phone Number Lists (#404), you can permit calls to a specific
number in that category by placing that number on an Allowed Phone Number
List. Using this procedure, you can create up to four lists of up to 10 telephone
numbers each.

Related Features

■

■

■

After completing this procedure, you must use Allowed List Assignments
(#408) to assign the Allowed Phone Number Lists to specific extensions.

Allowed Phone Number Lists override Disallowed Phone Number Lists
(#404) and Outgoing Call Restriction (#401), but not Line Access
Restriction (#302) or Night Service Button (#503) with a System
Password (#403). (There are other ways of overriding restrictions—see
Marked System Speed Dial Numbers, Emergency Phone List Numbers
(#406), and System Password (#403) for more information.)

The entries you must make to permit or restrict toll calls differ depending on
the setting for Toll Call Prefix (#402). This setting tells the system whether a
“0” (for operator-assisted calls) or “1” (for direct-dial calls) is required when
you make toll calls.

Considerations

■

■

Each list entry can include up to 12 digits. You can use the wildcard
character (by pressing the

 Hold  button on a system phone) to match any

single digit (it appears as “!” on the telephone display).
If you are restricting an extension from placing toll calls, do not place

numbers beginning with a “0” on an Allowed Phone Number List for the
extension. Once a user is active on an operator-assisted call, the user will
be able to avoid dialing restrictions by asking the operator to dial restricted
numbers.

Valid Entries

Up to 12 digits including 0–9 and  Hold  (any single digit)

Allowed Phone Number Lists (#407)

Examples

The examples below show how you would enter telephone numbers for an
Allowed Phone Number List in Step 4 of “Programming.” When an Allowed List
is assigned to an extension, users can dial numbers on that list, even if the
numbers would otherwise be restricted.

■ Specific Telephone Numbers. Enter the phone number exactly as you

would dial it. For example, to allow calls to the number 201 555-1111, make
the following entries:

–

Toll Call Prefix required

12015551111

–

Toll Call Prefix not required

2015551111

extensions—see “Related Features” below.

Related Features

■

■

■

■

A user can answer an outside call, an intercom call, or a transferred call that
is ringing at a specific extension or at any extension in a group. For more
information, see Call Pickup and Group Pickup.

A user can use Direct Line Pickup—Active Line to answer calls on lines
not assigned to the user’s phone.

A user can join a call in progress at another extension, as long as Privacy is
not on for that extension. See Joining.

A user can program the Voice Interrupt on Busy Talk-Back feature on a
button with lights to respond to a voice interrupt on busy call. Also see

Voice Interrupt On Busy (#312).

Considerations

■ If you are using an MLC-6 cordless phone, make sure the handset is on

before using the following instructions.

■

There are several ways to access a line for answering calls:

On either a system phone or a standard phone, lift the handset to answer
a ringing call (if more than one call is ringing at a system phone, you get
the call that has been ringing for the longest time).

On a system phone, press a specific line or

Auto Dialing

Description

This Telephone Programming procedure lets users dial outside numbers,
extension numbers, feature codes, or account codes with a single touch, by

pressing a programmed button. An Auto Dial number can be stored on any
programmable button (a button with no line assigned) on a system phone.

Related Features

■

■

To set up a Fax Management button, program the fax extension number on
an Auto Dial button with lights. Special light patterns on the Auto Dial button
for the fax extension indicate fax machine status. Chapter 4 provides more
information on using a Fax Management button. Identify fax extensions

using Fax Machine Extensions (#601).

You can include special functions, such as a Pause, in the Auto Dial
number. Special Dialing Functions provides more information on these
functions.

Considerations

■

■

■

■

■

■

■

If you program an extension number on a button with lights, the lights show
calling activity at the extension (see “Lights” in Chapter 3). Similarly, you
can connect an MLS-CA24 Intercom Autodialer to the system phones at
extension 10 and 11 to have Auto Dial buttons for all of the extensions in
your system (up to 24); this lets the users at extensions 10 and 11 transfer
calls to any extension by pressing one button, and view call activity at all
extensions with a glance.

Each user can have only one Auto Dial button—either on the system phone
or on the MLS-CA24 Intercom Autodialer—for another extension in the
system.

When programming emergency numbers for Auto Dialing and/or making
test calls to those numbers, you should: 1) Remain on the line and briefly
explain to the dispatcher the reason for the call before hanging up and 2)
Perform such activities in the off-peak hours, such as early morning or late
evening.

Auto Dial buttons do not override dialing restrictions for an extension.
MLS-6 and MLC-6 system phones only have four buttons available for lines

and/or features.
For PBX or Centrex systems that require a dial-out code to make calls

outside the PBX or Centrex system, include the dial-out code on an Auto
Dial button for a number outside the PBX or Centrex system.

Auto Dial buttons can be programmed only on system phones.

Automatic Extension Privacy (#304)

Description

This System Programming procedure lets you either allow users to join active
calls at an extension or prevent users from joining active calls at the extension.
When Automatic Extension Privacy is Assigned for an extension, other users
cannot join active calls at that extension. This feature is typically used for
standard phones and extensions connected to fax machines, modems, and
credit card scanners, which make and receive data calls that should not be
interrupted.

Related Features

■

■

To manually change an extension’s Privacy state, users can program the
Privacy feature on a button with lights. Users can then press the Privacy
button to activate the feature (green light on) or deactivate the feature
(green light off) when they want someone to join a call at their extension. (If
Automatic Extension Privacy is Assigned at an extension, the green light is
lit automatically after programming the Privacy button to indicate that
Privacy is currently active. If this is the case, and the Privacy button is
pressed, the feature is deactivated. To activate Privacy again, you must
press the button.)

This feature applies only to active calls. Any user can retrieve a held call
unless Exclusive Hold is used.

Considerations

■

If you want to be able to intercept calls routed to an auxiliary device—such

as an answering machine, voice messaging system, or PARTNER

Attendant—make sure Automatic Extension Privacy is Not Assigned for the

auxiliary equipment extension.

■ Standard phones and system phones without a programmed Privacy button

cannot override this feature once it is assigned to an extension.

Automatic Extension Privacy (#304)

Automatic Line Selection

Description

Related Features

This Telephone Programming procedure determines the line a user is
connected to after lifting the handset to make a call. When the user picks up the

handset, the system looks for lines in the order specified by this procedure and

selects the first available line. For example, if you specify outside lines first for
an extension, but all outside lines are busy, the user will hear the intercom dial
tone after lifting the handset.

■

■

To copy the Automatic Line Selection setting (as well as other system
settings) to other extensions, you can use Copy Settings (#399).

If Forced Account Code Entry (#307) is assigned to an extension,
Automatic Line Selection is not active for that extension. This means the
user must manually select a line after entering a required account code.

Considerations

■

■

■

■

■

■

This feature must be programmed from extension 10 or 11 only, using
Centralized Telephone Programming. Individual users cannot program this
feature directly.

You should program Automatic Line Selection when you first enter
Centralized Telephone Programming, before programming any other
features. However, if you want to program both Automatic Line Selection
and Extension Name Display (which also must be programmed when you
first enter Centralized Telephone Programming), first program Automatic
Line Selection, then exit and re-enter Centralized Telephone Programming
again to program Extension Name Display.

For standard touch-tone or rotary phones, or for any phone used mainly to
call other extensions, program the extension to select intercom first.

For combination extensions, the automatic line selection for both devices
(including a standard device) follows the automatic line selection for the
extension.

For hotline and doorphones, program the extension to select only the
intercom, with no outside lines in the selection sequence.

You do not need to include all available lines for an extension, only the ones
you want the system to search through and connect automatically.

Valid Entries

Outside lines 01–12, Left Intercom ✔

Automatic Line Selection

5-15

Examples

System Phone

With Automatic Line Selection at its factory setting, the system first searches to
find an idle outside line in numerical order (starting with line 1). Then, if all
outside lines are busy, the system searches for an idle intercom line. This order
can be changed, however, to accommodate your business needs. For
example, a telemarketing firm with a WATS line (line 5) to reduce telephone
expenses would set Automatic Line Selection for all telemarketers’ extensions to
“5, 1, 2, 3, 4, Intercom.” This way the WATS line would be selected first.

Standard Phone

If a standard phone user intends to place intercom calls and access system
features, Automatic Line Selection for his or her extension should be set to
intercom first for proper operation. For example, the setting for a standard
phone in a lobby, used for internal calling or making local calls on line 1, would
be set to “Intercom, 1.”

Considerations

■

■

■

■

■

If you use the Background Music feature to broadcast certain copyrighted
music or material, including songs or other material from radio broadcasts,
you may be required to obtain the permission of the copyright owner. One
way to obtain permission is to contact ASCAP, BMI, and/or similar
