This 945 telephone is fully compatible with any AT&T Four-Line Intercom
Speakerphone 984 or 974 units you may have installed. You can use a total
of 16 945/974/984 units together as extensions in your phone system.
This 945 telephone is also compatible with any AT&T 964/955/944 phones
you have previously installed. This 945 telephone is NOT compatible with
any 843, 853, 854, 874, or 954 telephones you may have previously installed.
NOTE: If you have one or more 964, 955, or 944 phone(s) installed in
the same phone system with this 945 telephone, you can only have 12
extensions and 15 telephone lines in the phone system.
• You must have a modular telephone jack and an electrical outlet not
controlled by a wall switch near where you’re installing the phone.
The total length of telephone wiring used in this system MUST
NOT be more than 600 feet. In some cases a Z800A filter can
be used in a phone system with more than 600 feet of wire.
AT&T highly recommends that a Z800A filter be installed by a
professional. AT&T CANNOT guarantee that this telephone
will work with such a filter, and IS NOT responsible for such
installations. A Z800A filter can be obtained by calling
800 222-3111.
• Identify the number of phone lines you’ll use.
• Plan the layout of your phone system.
• All connected phones must have the same Line 1 phone number
for the Intercom and Page features to work.
Every individual phone in your telephone system MUST be
assigned a unique extension number for the Intercom feature to
work. All system phones will sound an error tone until you assign
separate extension numbers to each unit. For directions see
"Assign an Extension Number to Your Phone" on page 21 of this
manual for directions.
• Decide if you want a private line. A private line does not appear
on all connected phones.
• Choose your setting for each feature. You will need to program
the features after installation (see “Programmable Features List”
beginning on page 6 for a brief description of the features. See the
FEATURE SETUP section beginning on page 18 for programming
instructions.)

DSL Users
Installation of a DSL splitter and an AT&T Z800A filter is required
to use the advanced features of this telephone if you have DSL
(Digital Subscriber Line) service.
Set-Up for DSL Users
If you are a DSL (Digital Subscriber Line) customer, you may experience
interference with the advanced features of this telephone. Certain features
of this phone (e.g., intercom, hold, line privacy, etc.) work by sending a data
signal using Line 1. This data signal is sent at some of the same frequencies
as those used by your DSL service. Microfilters are used to block the high
frequency DSL signals from being transmitted through and interfering with
your telephones. These same microfilters that may have been installed for
your DSL service will also block the data signals between your system
phones . Therefore, some features of this phone may not work properly
when DSL filters are installed in your building. This problem can occur even
if the DSL line is not one of the lines used by the phone system. If you use
the microfilters that your DSL service provider may have supplied when you
activated DSL service with this phone, some of the phone features will not
work. Once the DSL splitter (described below) is installed, you will no
longer experience interference.
Installation, by your DSL service provider or other professional, of a DSL
splitter (not a"microfilter") AND an AT&T Z800A Isolation filter as close
as possible to the "protection block" or "network interface" (where the
telephone line enters the house) may resolve DSL interference. (It may be
necessary to use a DSL splitter intended for outdoor use.) A DSL splitter
allows the data and voice signals to use the same telephone line without
interfering with each other. An AT&T Z800A filter isolates the splitter from
your phone system and reduces interference with the signals used by the
system phones to communicate with each other.
You can obtain an AT&T Z800A filter at no charge by calling 800 222-
3111. You will also receive a diagram showing the proper installation of
the AT&T Z800A filter with a DSL splitter, DSL modem and your system
phones. AT&T cannot supply the DSL splitter.
Please contact your DSL service provider or professional contractor for
details about obtaining and installing a DSL splitter. Your DSL service
provider may require you to bear any installation costs. AT&T and the
manufacturer of this product have no affiliation with your DSL provider
and the type or quality of services they offer. Installation must be performed
at your own expense and AT&T cannot troubleshoot or provide installation
support.
BEFORE YOU BEGIN
BEFORE YOU BEGIN

NOTE: If your DSL service provider cannot supply a DSL splitter, it is
possible to purchase an outdoor DSL splitter (such as a Corning or Allen
Tel brand DSL splitter) over the Internet.
If you are a new DSL customer, your DSL service provider will likely ask you
if you have more than one telephone line in your home or business. If you
answer yes, your DSL service provider will probably advise you that you need
a splitter. Your DSL service provider may also ask if you are installing a phone
system. If you answer yes, your DSL service provider will most likely advise
you that you need a splitter. In most cases, your DSL service provider will
supply you with the proper splitter for your specific situation. The DSL
splitter, installed properly and in conjunction with a Z800A filter, should
help overcome any interference between the DSL signal and the signals
sent by your phone system.
AT&T shall not be responsible for the cost of installation, any damages, lost
business, direct or indirect expenses accrued or associated with installation,
or other compatibility issues which may arise as a result of using this product
while you subscribe to DSL service.
