Terms and Conventions Used

“Related Documents,” later in this section, provides a complete list of system
documentation together with ordering information.

In the U.S.A. only,

(1-800-628-2888) 24 hours a day. Call the Helpline, or your AT&T
representative, if you need assistance when installing, programming, or
using your system.

AT&T provides a toll-free customer Helpline

Terms and Conventions Used

In this document, the terms in the following list are used in preference to

other, equally acceptable terms for describing communications systems.

Lines, Trunks and Facilities

Facility is a general term that designates a communications path between a
telephone system and the telephone company central office. Technically a
trunk connects a switch to a switch, for example the MERLIN LEGEND
Communications System to the central office. Technically, a line is a loop­start facility or a communications path that does not connect two switches,
for example, an intercom line or a Centrex line. However, in actual usage, the
terms line and trunk are often applied interchangeably. In this book, we use
line/trunk and lines/trunks to refer to facilities in general. Specifically, we refer
to digital facilities. We also use terms such as personaI line, ground-start
trunk, DID trunk, and so on. When you talk to your local telephone company
central office, ask them what terms they use for the specific facilities they
connect to your system.

Some older terms have been replaced with newer terms. The following list
shows the old term on the left and the new term on the right.

Programming Basics 1-1

System Programming Console

System Programming Console

The system programming console is an MLX-20L telephone connected to the
system programming jack. When you begin system programming on a new
system for the first time, the console must be connected to the first jack on the
first 008 MLX module or 408 GS/LS-MLX module (Release 2.0 and later
versions). This jack is factory set as the system programming jack and as an
operator position. When you program for the first time, you can change the
system programming jack to any one of the first five jacks on the first 008 MLX
module or 408 GS/LS-MLX module (Release 2.0 and later versions). This
allows you to program without interfering with the operator’s call handling.

You can also have one or two Direct Station Selectors (DSSs) connected to
the system programming console. Each DSS adds 50 extension buttons to the
console, which facilitates assigning features to telephones.

An MLX-20L telephone with a DSS is shown in Figure 1–1.

System Programming Console

Console Buttons

System programming is performed using the console’s 14 display-area
buttons. These buttons are arranged in two columns of seven buttons. The top
two buttons in each column have the same labels and functions regardless of
the screen display. This type of button is called a fixed display button. Table

1-1 describes the functions of the fixed display buttons.

Types of Programming

Listed below are the three types of programming available for the
communications system.

System Programming.

manager to program features that affect all or most system users, and
requires one of the following:

— An MLX-20L™ telephone connected to one of the first five jacks of

the first MLX module in the control unit.

This type of programming enables the system

— A PC with System Programming and Maintenance (SPM) software.

SPM emulates a system programming console on your PC. The PC
should be connected to the lower port (labeled ADMIN) on the
processor module. A PC with a modem can perform system
programming remotely through the public network or by
connecting to a tip/ring extension jack (012 or 008 OPT module) on
the communications system. A built-in modem in the processor
allows the PC and the communications system to communicate.

■

Extension Programming.

This type of programming enables
individual telephone users and system operators (except for QCC
operators) to change their telephone features to meet individual

needs. For details about extension programming, see the appropriate
user and operator guides.

1-6 Programming Basics

Programming Information

■

Centralized Telephone Programming.

This type of programming

enables the system manager to program any feature that can be

programmed by individual telephone users or system operators. Some

features can be programmed only in centralized telephone

programming. Centralized telephone programming can be done on
the programming console or on a PC with the SPM software. See
Chapter 5 in System Programming.

Idle States

Some programming procedures can be started only when the entire system,
or some part of it, such as a trunk or an extension, is idle (not in use). Some
procedures require that a trunk or extension be idle only at the instant of
programming. Lengthy procedures require the system, trunk, or extension to
remain idle until programming is completed. These procedures wait for the
system, trunk, or extension to become idle and then prevent the initiation of
any new calls. This condition is called forced idle.

NOTE:

If a procedure requires an idle condition, do the programming outside of

normal business hours.

If a procedure requires that the system be idle and the system is busy when

you begin, you see the screen shown in Figure 1-3.

hear a signal, indicating that the telephone cannot be used; display telephone
users see the message

Wait: System Busy;

single-line telephone users do

not hear a dial tone.

Line or Trunk Idle

Since these procedures require the line or trunk to be idle only at the instant of
programming, the line or trunk is not forced idle (as described in the previous

paragraph). The following procedures can be performed only when the line or
trunk being programmed is idle:

■ Identify loudspeaker paging extension jack.

■ Assign trunks to pools.

■ Specify incoming or outgoing DID or tie trunk type.

■ Specify tie trunk direction.

■ Specify tie trunk E&M signal.

Extension Forced Idle

When a telephone or data terminal is forced idle, no calls can be made or
received on that telephone or data terminal. The following procedures can be
performed only when the telephone or data terminal being programmed is
idle:

■

Assign call restrictions.

■

Assign pool dial-out restrictions.

■

Copy extension assignments.

■

The forced idle reminder tone is a high-low “doorphone” tone—400 ms of

667 Hz tone followed by 400 ms of 571 Hz. The tone is provided under the
following circumstances:

■

At the extension, to remind the user that the system or the extension is

in the forced idle state

■

At the programming console or at a PC running SPM, to remind the

system manager that the system (or at least one extension) is in the
forced idle state because of administrative activity

In Release 1.1 and higher of the communications system, forced idle reminder
tones occur every 20 seconds. You can adjust the volume of these tones with
the volume control.

position. The system programming position can be reassigned only to one of

the first five extension jacks on the first MLX module. Only one system

programming console is allowed per system.
If you are programming on the console, be aware of the following:

■ The console must be connected to the extension currently assigned

for system programming.

■ As soon as you change the system programming extension, the

system programming session is terminated. To proceed with system
programming, you must connect the system programming console to

the newly assigned extension and enter system programming again.

Automatic Maintenance Busy

Automatic Maintenance Busy

Automatic Maintenance Busy allows the system to take a malfunctioning trunk
out of service for outgoing calls (incoming calls are never blocked). This

prevents faulty outside facilities from causing disruptions in outgoing calling

patterns.
For optimal performance, enable Automatic Maintenance Busy for Hybrid/PBX

systems with pooled trunks.

NOTE:

No more than 50 percent of the trunks in a trunk pool are allowed to be placed
in the maintenance busy state at one time unless: the central office has failed
to disconnect a trunk (which prevents anyone from using that trunk); or an
entire trunk module is manually taken out of use (a maintenance-busy state
deliberately caused by the user).

Set Up Space.

This plan is for systems with a need to customize
extension numbers or use extension numbers of varying lengths (one
to four digits). All extensions are assigned 4-digit numbers in the 7000

range. Extension numbers 1000 through 6999 are also available for

use when you renumber.

In all three numbering plans, the system assigns 3-digit extension numbers to
pools (Hybrid/PBX only), calling groups, paging groups, remote access
codes, the Listed Directory Number, park codes, and Idle Line Access (Key
and Behind Switch modes). In addition, the system assigns 9 for Automatic
Route Selection (Hybrid/PBX only) and Idle Line Access (Key and Behind
Switch modes only). Zero (0) represents a special extension number—actually

a fixed dial code—for the primary operator or QCC queue. Any extension
number except 0 can be renumbered.

Extension numbers can be composed of any combination of digits; however,
no number can begin with 0. Trunk numbers (801 to 880) are considered to .

A system operator position, for a Queued Call Console (QCC) operator or a

Direct-Line Console (DLC) operator, should be programmed before you
program lines or trunks.

The Queued Call Console (QCC) operator position is available only for

Hybrid/PBX systems. The Direct-Line Console (DLC) operator position is
available in any mode and must be programmed if you have Call

Management Systems connected to any operator extension jacks.

Any combination of operator positions can be assigned as long as no more
than four operator positions are QCCs and the total number of operator

positions does not exceed eight.

If you want to designate a new operator position and the system already has
the maximum number of operator positions, you must change an existing
operator position to a nonoperator position before you designate a new
operator position.

NOTE:

When you change an extension to an operator position, or vice versa, the
system returns the port (extension jack) type of that extension to the factory
setting. You must reprogram lines and any features for that telephone or
console. You may also need to change any attached accessory equipment

and optional features.

4-2 System Operator Positions

Primary Operator Positions

Primary Operator Positions

The primary operator position is the extension to which your call is directed
when 0 is dialed on a System Access button. The first extension jack on the
first MLX module in your system is assigned as the primary operator position.

If your system has QCC operator positions, this position must be changed
from the factory setting (DLC) to a QCC operator position. (The primary
operator extension cannot be changed from the first extension on the first

MLX module.)

QCC Operator Position

The QCC operator position is available only for Hybrid/PBX systems. The DLC
operator position is available in any mode and must be programmed if you

have Call Management Systems connected to any operator extension jacks.

QCC System Operator Positions.
This procedure applies to Hybrid/PBX systems only.

IMPORTANT:

If you want to add or remove QCC operator positions, the following

conditions apply:

■ If other QCC positions remain in your system, the primary QCC

operator position cannot be removed.

■ When QCC operator positions are added, the primary QCC

operator position should be the first one added.

■ If QCC operator positions are being removed, the primary QCC

operator position must be the last one removed.

DLC Operator Positions

DLC operator positions can be assigned to the first and fifth extension jacks
on the first modules with digital or analog multiline extension jacks. A
maximum of eight DLC operator positions can be assigned. Any combination
of operator positions can be assigned as long as there are no more than four
QCC operator positions and no more than a total of eight operator positions.

Use this procedure to specify extensions that serve as central answering
positions for all incoming calls, for Call Management Systems (CMSs)
connected to operator extension jacks, or as calling group supervisor
extensions. (You do not need to use this procedure in a Key or Behind Switch
system unless you have more than one DLC position.) For a new system,
remove the factory-set DLC operator position assignment for any telephone
not used as an operator position.

Lines and trunks are assigned on individual buttons.

The system programming console can have several incoming calls ringing

simultaneously.

Each CMS requires two DLC operator positions to connect the equipment and
one position to serve as CMS supervisor.

Lines and Trunks 5-1

Type of Trunk

Separate sections cover “DS1 Facilities,”

“Tie Trunks,” “DID Trunks,” and “PRI

Facilities.”

A slot is the physical location of the individual module on the control unit.
There is a maximum of 17 slots which are numbered as follows:

■ Basic carrier: slots 1 through 5

■ First expansion carrier: slots 6 through 11

■ Second expansion carrier: slots 12 through 17

A port is a line or trunk jack on the module. Individual modules support
different numbers of ports. On any module, port 1 is the lowest physical jack

position. Lines connect equipment to the switch and trunks connect a switch
to a switch. Lines and trunks have logical IDs, a unique numeric identifier for
each extension and trunk jack in the communications system control unit.

Lines are numbered from 1 to 144, while trunks are numbered from 801 to

880. An MLX extension port has 2 logical IDs per 1 physical jack.

■ 400 GS/LS

■ 408 GS/LS

■ 800 GS/LS

■ 408 GS/LS-MLX

■ 800 GS/LS-ID (loop-start trunks only)

Any combination of trunk types (all loop-start, all ground-start, or some of

each) is permissible.

This procedure is not used for a system registered with a KF registration

number (Key or Behind Switch). Ground-start trunks are allowed only for
systems with an MF (Hybrid) or PF (PBX) registration number.

Disconnect Signaling Reliability

Disconnect Signaling Reliability

Use this procedure to classify the disconnect signal sent by the central office
on loop-start trunks as one of the following:

■ Reliable. Signal sent within a short time.

■ Unreliable. Signal may not be provided.

The setting selected applies to all trunks in the system because trunks cannot

be programmed individually. The reliable/unreliable setting does not apply to
loop-start trunks emulated on a T1 facility. If you specify a reliable disconnect

for trunks programmed with a short hold disconnect interval (see “Hold

Disconnect Interval”), active calls as well as trunks on hold maybe
disconnected. For more information about reliable and unreliable disconnect
and its implications, see the Feature Reference.

Hold Disconnect Interval

Hold Disconnect Interval

Use this procedure to specify the number of milliseconds before a loop-start
line/trunk is released when a caller on hold hangs up and abandons the call.
This can be specified as either a long interval (450 ms) or a short interval (50
ms). The hold disconnect interval applies to loop-start trunks connected to
400, 408, or 800 modules; it does not apply to emulated loop-start trunks (T1
facility).

NOTES

Principal User for Personal Line

Principal User for Personal Line

Use this procedure to assign or remove one telephone as principal user for a

personal line. When a telephone with Remote Call Forwarding activated is
assigned as principal user, calls received on the personal line are forwarded
to an outside telephone number. In addition, calls received on that line are
sent to that telephone’s individual and/or Group Coverage receivers unless
the personal line button is set to No Ring.

The principal user assignment must be removed before the trunk can be

removed from a button on the telephone.
When no principal user is assigned for a personal line, calls received on the

personal line are not forwarded to outside telephone numbers; calls received
on the personal line follow the coverage patterns for all users who share the
line.

Incoming Call Line Identification (ICLID) Delay

Incoming Call Line Identification
(ICLID) Delay

Use this procedure to delay the alerting (ringing) of LS-ID calls to all

extensions until approximately six seconds have elapsed since the port

module informed the system software that the line was ringing, or the system
software has been informed that ICLID information is available, whichever
comes first.

This option can be programmed on a per trunk basis. It gives the appearance
to the users that the ICLID information is available the moment the call arrives

at the extension, and prevents applications or adjuncts from answering the

call too soon.
The LS-ID Delay option appears on the Ground-Start/Loop-Start Trunk

Information report.
Any extension or adjunct that answers an incoming CO line on the first ring

causes the ICLID information associated with the call to be lost. The adjunct .

must be programmed to either answer the call on the second (or later) ring, or
the call must be delayed. The call can be delayed by setting the ring option

on the buttons associated with the adjunct or by using the LS-ID Delay option.

NOTE:

Caller ID is available only on loop-start lines/trunks.

Trunks to Pools Assignment

Trunks to Pools Assignment

Use this procedure to create trunk pools (groups of outside lines/trunks
connected to the system). Trunk pools are used to specify preferred routes for
Automatic Route Selection (ARS). In addition, trunk pools enable users to
select a line/trunk by dialing a pool dial-out code or by pressing a single

button on the telephone. (A separate button for each line/trunk is not needed.)

Each pool should contain trunks of the same type (for example, loop- or
ground-start or WATS); however, ground- and loop-start trunks of the same
type can be included in the same pool. Ground-start trunks must be manually
assigned. A maximum of 11 trunk pools are allowed. A trunk can be assigned
to only one pool.

Do not mix different service areas of WATS (Wide Area Telecommunications
Service) trunks or FX (Foreign Exchange) lines to different cities. Do not

include both incoming only and outgoing only lines/trunks in a pool.

If you want to reassign a line/trunk to a different pool, you must remove it from

the current pool before you assign it to the new pool. Once you assign a

line/trunk to a pool, it can be assigned to a button only on a direct-line

console operator position; individual lines intended for personal use on

telephones other than the DLC console should not be assigned to pools.

DID trunks cannot be grouped in pools.
pools and must be removed manually if

on Hold, or maintenance alarms.

Dial-in tie trunks should not be grouped

If you are using Automatic Route Selection, the main pool (factory-set dial-out

code 70) must contain loop- or ground-start trunks.

The system provides an error tone when a line/trunk is in use or if a

loudspeaker paging system, Music on Hold, or maintenance alarm is already
assigned; however, the system does not indicate the reason for the error

Use this procedure to copy options assigned to loop-start or ground-start

trunks, Tie trunks, or DID trunks. Note that many of these options apply to

Hybrid/PBX systems only. The following information is copied for each

line/trunk type:

■

Loop-Start or Ground-Start Trunks

facilities). Toll type, signaling type, and trunk pool assignment
(Hybrid/PBX only.)

■

Tie Trunks.

Direction, Tie trunk type, E&M signal, dial mode, dial tone,
answer supervision time, disconnect time, and trunk pool assignment
(Hybrid/PBX only).

■

DID Trunks

(Hybrid/PBX only). Block assignment and disconnect

time.

(including those emulated on T1

To find out whether there is an optional feature assigned that you would like to

copy, use

Inspct

from the system programming console or [PgDn] on a PC.

NOTES:

You can copy options to a block of lines/trunks only if they are all the same

1.
type (loop-start, ground-start, Tie, or DID). If you attempt to copy
assignments and there is mismatch in line/trunk type, information is copied
to that point only. You receive no error message.

If you are copying options to a block of lines/trunks, they must be

2.
sequentially numbered.

If the block you are copying to includes an invalid line/trunk type, the

3.
copying process stops at the invalid type. Only the lines/trunks that were
copied to before the invalid type was found are copied successfully.

If you are copying assignments to a block of lines/trunks and one of the

lines or trunks is in use, you see the message
your display. The copying for the rest of the lines/trunks in the block is
delayed until the busy line/trunk becomes idle. If you exit without waiting

for the copying to complete, the copying done up to that point is not

canceled.

Use the procedures in this section to program the following options for DS1

facilities (T1 or PRI) connected to a 100D (DS1) module:

■ Type of DS1 facility

— T1
— PRI

■

Frame Format

■ Zero Code Suppression

■ Signaling Mode

■ Line Compensation

■ Clock Synchronization

■ Channel Service Unit

Type of DS1 Facility

Type of DS1 Facility

Use this procedure to specify the type of facility (T1 or PRI) connected to a

100D (DS1) module. If T1 type is programmed, and the channels are used for
emulation and/or AT&T Switched Network (ASN), you must specify the type of
channel emulation. If the type is T1 and the type of channel emulation is tie
trunk, you must specify the transmit/receive loss parameter settings are also
selected. The two valid settings are as follows:

■ TIE-PBX. Select when emulated tie trunks are used to connect to

another communications system (such as PBX or Centrex). The

transmit/receive parameter is set to 0/4.

■ Toll. Select when emulated tie trunks are used for ASN services (such

as Megacom®, Megacom 800, or Software Defined Network). The

transmit/receive parameter is set to 0/6.

If you select T1, channels can emulate ground-or loop-start trunks, tie trunks,
or DID trunks in any combination. Note that unused channels must be
specified as unequipped.

If either T1 or PRI is selected, channels can be used for ASN services. When
T1 channels are used for ASN services, each channel must be programmed
for tie trunk emulation.

If you select PRI, you must also perform additional procedures. At a minimum,

the Framing Mode and Zero Code Suppression procedures must be

performed. See “PRI Facilities” for more information.
