started with the PARTNER system is to read this manual straight through. If
you’re in a hurry to set up and use the system, you can read this chapter and
use the Quick Start table on page 1-6. But you will eventually need to read this
manual to learn about all the capabilities of the system and how it can work for
you.
The PARTNER system can handle as many as 4 outside telephone lines and 12
extensions. The PARTNER system has many features that help you manage
your phone calling and save money. For example:
n

answering machines, and fax machines means you do not have to buy extra
lines or expensive adapters to connect phone equipment you may already
own.
Easy, one-touch use of features such as Last Number Redial and Privacy
with AT&T MLS-12™ phones.
Auto Dialing makes it possible to dial long or frequently used numbers with
a single touch.
System Speed Dialing allows people to dial frequently called numbers by
dialing a short code.
Dialing Restriction feature allows you to keep phone bills down by
restricting the kinds of calls people can make.
Interchangeable system parts make it easy to add or remove modules to
expand or repair your system.

							System Components
206 MODULEMODULE CONNECTORA system can have one or two 206modules. Each 206 module connectsup to 2 telephone company linesand up to 6 telephones or otherdevices such as fax machines,
answering machines, and modems.
With two 206 modules, you can
connect 4 outside lines and
12 extensions. Each 206 module
has a green light that shows it is
turned on.

This connector is needed only if you
have two 206 modules. It joins the
modules together so that all the lines
and telephones on both modules are
connected.

							Optional Equipment
The PARTNER system works with many telecommunications devices, not only
PARTNER telephones. You can connect these other devices without investing in
more lines or circuit cards.
Industry Standard Devices
Many types of industry-standard telecommunications devices will work with your
PARTNER system. They include:
n
n
n
n
n
nStandard single line touch-tone and rotary telephones. You can use
these phones for almost all of your normal phone calling. In fact, you should
connect at least one standard phone to the system because it is the only
kind that will work on the PARTNER system during a power failure. See
chapter 5 for instructions on using standard phones.
Single-line cordless telephones. You can use single-line cordless tele-
phones for almost all of your normal phone calling while having the freedom
to move around your premises.
Fax machines. You can save money by connecting your fax machine to the
PARTNER system, so you do not have to pay for an extra dedicated outside
line. For information on how to use a fax machine with the PARTNER system,
see chapter 6.
Answering machines. With the PARTNER system, you can cover up to four
Iines with a single answering machine. For instructions on how to use
answering machines with the PARTNER system, see chapter 6.
Modems. You can use a modem with your personal computer to send and
receive data over telephone lines. For instructions on how to use modems
with the PARTNER system, see chapter 6.
Credit card verification terminals. If you use a credit card verification ter-
Limitations
minal, you can connect it directly to your PARTNER system. For instructions
on how to use a credit card verification terminal with the PARTNER system,
see chapter 6.
You can connect the above devices to your system regardless of the manufac-
turer. However, the following limitations apply:
n
n
nIt must be a single-line device.
It must be industry standard. 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.)
In order for the phones or devices to ring properly, the total Ringer
Equivalence on a single extension cannot exceed 2. Every device has a
label showing its Ringer Equivalence Number (REN). If you are connecting a
single device to the extension, its REN cannot be more than 2. If connecting
two devices, their total RENs cannot be more than 2.
System Overview  1-3 
						

							Connecting and Using
Standard DevicesYou can connect the standard device so that it is on an extension by itself, or it
can share an extension with another piece of equipment (either another stan-
dard device or a PARTNER phone). To connect two devices on one extension,
you will need an AT&T 267F2 bridging adapter. (Two of these bridging adapters
are included with each 206 module.) ln addition, the total RENs for both dev-
ices must not exceed 2. See pages 2-12 and 2-13 for installation instructions.
For information on using standard devices with your PARTNER system, see
chapters 5 and 6.
Other Devices
You can also connect other devices to your system, but only specific models are
compatible with the PARTNER system. Contact an AT&T sales representative
for datails. These devices include:
n
n
nLoudspeaker paging systems. Allows you to broadcast a message over a
large area.
Headsets. A headset is a combination earphone and microphone you wear
on your head, so you can have a private, hands-free conversation. It is use-
ful for receptionists, salespeople, or others who may need to use have their
hands free while talking on the phone. For information on how to use head-
sets, see the manufacturer’s instructions.
Extra alerts. You can connect extra alerting devices, such as bells or horns,
to ring when a call comes in. For information on how to use these alerts, see
the manufacturer’s instructions.
