This 945 telephone is fully compatible with any AT&T Four-Line Small Business System 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 have only 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 the cost of such installations or for arranging the installation. A Z800A filter can be obtained by calling

1 800 222-3111.

• 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. If you try to assign the same extension number to a second phone, you will hear a repeating short ring and the screen display will include EXT XX is already used Assign new EXT #. For directions see "Assign an Extension Number to Your Phone" on page 22 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 21 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 should 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 1 800 222-

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

945 CIB 2ATT 3/14/05 9:58 AM Page 4



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.

EXPANDING THE PHONE SYSTEM

When you combine two or more 945/974/984/944/955/964 phones you create an interacting system where phones share lines. If you have only 945/974/984 phones on your phone system, you can have up to 16 phones and up to 19 telephone lines. If you have one or more 944/955/964 phones in your phone system, you can have up to 12 phones and up to 15 telephone lines. The system can be expanded with or without Centrex service.



NOTE: All 945 features work as described earlier in this manual.

Line Groups

When phones share lines, the LINE lights let users at different extensions know when a specific line is in use. For accurate LINE lights, the same lines must be connected to each extension in the Line Group, and they must have the same incoming telephone number at each extension.

The chart below shows 16 extensions, each sharing the first three lines, but being assigned to different Line Groups based on other shared or private lines.

Setup Checklist

Before expanding your system or installing for Centrex, review the installation checklist. If you have Centrex, contact your local telephone company for further information about Centrex service.

• The phone number for Line 1 must be the same on all phones in order for the Intercom and Page features to work.

• Determine the number of phones that will be on the system.

• Identify the phone that will be the Console phone.

• Identify the private line for the Console phone. The Console phone must have its own private line. This line is not shared with any other phone.

• Follow the regular installation instructions in this manual.

• Enable the Console phone.

• Store the Centrex pickup codes and the seven-digit phone numbers in One Touch locations. (See ONE TOUCH OPERATION beginning on page 50.)

Enabling the Console Phone

Determine which phone will be the Console phone for your system and program the Console following the directions to “Set This Phone to be the Centrex Console Phone” on page 36. It is recommended that Line 4 of the Console be programmed as a private line, to be sure a line is available for Centrex access.

Once another system phone has enabled its delayed ring, the Console phone will receive those calls. All the 945 features work in the same manner as described in this manual.

The Console phone can pick up other Centrex lines through Centrex switching. You can store the Centrex pickup codes and the seven-digit phone number of each station, except for the Console phone, in the One Touch locations.

Setting Ring Delay Duration

This feature allows other system telephones’ calls to ring at the Console phone. After a specified ring delay, the calls will ring at the Console phone. (See “Set the Centrex Console Delayed Ring Time” on page 37.)

Answering a Delayed Ring

The Console phone rings and the screen displays the extension number of the intercom sending the delayed ring.

1 Select a free line. 2 Enter the Centrex pickup code. 3 Enter the seven-digit phone number of the extension sending

the delayed ring.



NOTE: If the Console is using another line and receives a delayed ring,

the Console phone can put the other line on hold and follow Steps 1–3. If the Console is on an intercom call, the intercom call should be ended before picking up the ringing phone.

Picking Up Another Station’s Line

1 Choose a free Centrex line. 2 Enter the Centrex pickup code. 3 Enter the seven-digit phone number of the line you want.
