Installation
Overview
This guide explains how to install the system. It begins with an example system
setup, then follows with an illustration of the components you need to install the
system and general guidelines to consider before installation. Next, it provides
step-by-step instructions for connecting and testing the components for initial
installation and upgrades. Finally, it ends with important system specifications
and requirements.
If your company already has modular jacks for all outside lines and extensions,
you may be able to use the existing wiring to install the system hardware and
connect telephones to the system yourself. To have an AT&T service technician
install and customize your system or change existing wiring, call 1 800 247-7000
(in the continental U.S. only) or call your AT&T Authorized Dealer.
After installation, refer to the PARTNER Plus Communications System
Programming and Use guide for programming instructions.
Overview
1
An Example System Setup
The next page shows a control unit with two 206 modules and
two 400 modules, giving the system a capacity of 12 outside
lines and 12 extensions. Although your system may differ, this
example will give you an idea of the types of equipment you
can connect to it. In the example, system phones and
industry-standard devices are connected to nine extensions.
The circled numbers in the figure refer to the following list,
which gives a brief description of the system’s hardware
components.
Control Unit
The control unit consists of these components:
Backplane. The backplane channels power to the
system and connects the system modules.
206 Modules. Each 206 module has jacks for two lines
and six extensions.
400 Modules. Each 400 module provides four line jacks
but no extensions. Notice that the 400 modules are
installed to the right of the 206 modules.
Processor Module. The processor module contains the
software that provides the system’s features. It also has
PAGE, SMDR, and MUSIC ON HOLD jacks.
PAGE Jack. A loudspeaker paging system plugs
directly into this modular jack. The system is compatible
with any AT&T paging system, including the AT&T
PagePac6® shown here.
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. Or you
can purchase a Magic On Hold system from AT&T,
which does not required you to obtain such as license.
SMDR Jack. A call reporting (or SMDR–Station
Message Detail Recording) device connects directly to
this jack. AT&T’s Call Accounting Terminal serial printer
and box are shown here.
MUSIC ON HOLD Jack. AT&T’s Magic on Hold® is
connected to this jack to provide customized music and
messages for callers on hold. Other types of audio
equipment (including a CD player, cassette player, or
stereo receiver) can be connected using an audio cord
with an RCA phono plug (not supplied).
Line Jacks. The top two jacks on each 206 module, and
all four jacks on each 400 module, connect to outside
telephone lines.
Extension Jacks. The bottom six jacks on each 206
module connect inside wiring for telephones and other
telecommunications equipment.
Network Interface Jacks. These jacks provide access
to telephone lines from the local telephone company.
Each outside line is connected to the system by
plugglng one end of the line cord into one of these jacks,
and the other end into a Iine jack on a 206 or 400 module.
Extensions
Various devices—including system phones and industrystandard devices—can be connected to the modular wall
jacks. The modular wall jacks connect to the extension jacks
in the control unit by way of the building’s inside wiring.
Extension 10: These devices are connected:
■
MLS-34D Display Phone. Typically, the receptionist
on programming extension 10 has an MLS-34D
display phone like the one shown here. The display
shows the time, dialed numbers, the duration of calls,
and programming messages.
An MLS-34D, MLS-18D, or MLS-12D is required for
system programming at extension 10 or 11, or both.
Use an MLS-18D only if there are no MLS-34D phones
in the system. Similarly, use an MLS-12D only if there
are no MLS-34D or MLS-18D phones in the system.
■
Call Assistant™ Intercom Autodialer. An Intercom
Autodialer is connected to the phone, for dialing
extensions and transferring calls to them with one
touch and for seeing which extensions are busy.
■
Standard Touch-Tone Phone. During a power
failure, the MLS-34D phone on extension 10 will not
work, but the receptionist can use the standard phone
to place and receive calls on line 1.
Extension 11: MLS-34D Display Phone. Another
MLS-34D is connected to programming extension 11.
This means you can program the system from this
extension while the receptionist at extension 10 is free to
handle calls.
Extension 12: MLS-18D Phone and Answering
Machine. An MLS-18D phone and an answering
machine are connected to this extension.
Extension 13: Standard Phone. A standard phone
(such as you might have in your home) is connected
directly to the extension jack.
Extension 14: Doorphone. A doorphone is installed at
the building entrance. When someone at the entrance
presses the button on the doorphone, the designated
extensions in the office ring automatically. (Any number
of extensions can be designated as doorphone alert
extensions.)
Extension 15: Bell. A loud bell is connected directly to
this extension jack. Any line programmed to ring on
extension 15 activates the loud bell—to alert users of an
incoming call in a large area, such as a warehouse.
Extension 16: MLS-12D Display Phone. This display
phone can handle 10 outside lines.
Extension 17: Fax Machine and Standard Phone. A
fax machine and standard phone share this extension.
This lets you have the use of another phone when the fax
machine is idle. (You can use a system phone at
another extension to monitor fax machine activity—see
“Fax Management Feature” of “Using Fax Machines” in
Chapter 4 of the PARTNER Plus Communications System
Programming and Use guide.)
Extension 18: MLC-6 Cordless Phone. An AT&T
MLC-6 cordless phone is connected to this extension. It
works like the corded MLS-6 system phone.

You will need to obtain four #12 screws of the appropriate type for the wall and
weight of the control unit (a control unit with four 206 modules and a processor
module weighs approximately 27.5 pounds or 12.3 kilograms).
In addition, if you need modular telephone cords for connecting the extension
jacks on the control unit to the modular connecting blocks for extensions in the
equipment room, short telephone cords for wall mounting MLS-model phones,
or a 355A/355AF adapter and D8W telephone cord for connecting a call
reporting device, order them before installation. Refer to “Product Ordering
Information” in Appendix B of the PARTNER Plus Communications System
Programming and Use guide for ordering instructions.
NOTE:
A system display phone—either an MLS-34D, MLS-18D, or MLS-12D—is
required for system programming at extension 10 and/or 11. (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.)

Combination Extensions
You can connect a standard device (such as a standard phone or an answering
machine) 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). An
extension with two devices connected to it is called a combination extension.
You cannot install two system phones on the same extension, and the combined
REN (Ringer Equivalence Number) of two devices on one extension cannot
exceed 2.0. (The REN for a system phone is 0.0.)
If your system phone has a built-in auxiliary jack, you can connect a standard
device directly to the phone, without using a bridging adapter—see “Using A
Direct Connection” below. If your system phone does not provide a built-in
auxiliary jack or if you want to connect two standard devices together, you must
use an AT&T 267F2 bridging adapter to combine the two devices on one
extension—see “Using a Bridging Adapter” below.

To connect a phone, plug the modular telephone
1
mounting cord into a modular wall jack or directly into a
206 module extension jack. (If you are connecting a
standard phone and its mounting cord is loose, try an
AT&T D2R mounting cord instead.)
To install two phones (or other devices) on a single
extension jack, see “Combination Extensions” earlier
in this guide
A)
2
Test the telephone for proper operation—to test
the power and lights on a system phone,
press and hold the [ # ] button for five seconds.
B)
Before releasing the [ # ] button, lift the handset.
All lights should light, the ringer should sound,
and (on the MLS-34D, MLS-18D, or MLS-12D
phones only) a test pattern should appear on
the display. (If not, call the appropriate
support telephone number as instructed on
the inside front cover.)
C)
Replace the handset; the phone is now in normal
operating mode.

Connecting Paging, Music-On-Hold,
and Call Reporting (SMDR) Devices
Only steps for connection to the processor module are
provided here. Refer to Chapter 4 of the PARTNER Plus
Programming and Use guide and the manufacturer’s
instructions for additional information on installing,
programming, and using these devices.
Paging System
Insert the modular plug into the PAGE jack on the
1
processor module.
2
Route the cord as you did for line and extension
cords, then connect it to the paging system.
Music-on-Hold Audio Source
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. Or you
can purchase a Magic On Hold system from AT&T,
which does not require you to obtain such a license.

cords, and then connect it to the audio source.
First set the unit’s volume to the lowest setting. Use
A)
a flathead screwdriver to turn the volume
control on the processor module
counterclockwise until it stops.
Place a call on hold and listen while adjusting
B)
the volume, clockwise. If you do not hear
music at any setting, check “Music On Hold

Connecting Intercom Autodialers
Since the autodialer has a fixed stand, you may need to
adjust the height of the system phone—by installing a
stand—to match the height of the autodialer. Refer to
Step 2 of “Desk Mounting” under “Assembling System
Phones” for instructions.
You can wall mount an Intercom Autodialer to work next
to a wall-mounted system phone; however, wall-mounting
system display phones is not recommended.
A)

2
Unplug the phone’s modular telephone cord from
the jack on the bottom of the phone and the
wall jack, and save the cord for Step 1D.
Plug one end of the D8W cord, supplied with the
B)
autodialer, into the jack on the bottom of the
phone. (If the phone has multiple jacks, plug
the cord into the “LINE” jack.)
Route the other end through the groove at the
C)
back of the autodialer and plug it into the OUT
jack.
Route one end of the modular telephone cord
D)
through the groove at the back of the
autodialer and plug it into the IN jack; plug the
other end into the wall jack for extension 10 or
11.
A)
Connect the keyed power cord, supplied with the
autodialer, to the POWER jack on the bottom
of the autodialer, routing it through the groove
as you did in Step 1.
If the keyed power cord is not attached to the
B)
power supply unit, plug the free end of the
cord into the modular jack on the power
supply unit; otherwise, go to Step 2C.
