An Example System Setup

This PARTNER Plus System has 4 outside lines and 8 extensions connected to a variety of PARTNER phones and other equipment. The boldface numbers refer to the following list which gives a brief description of the system’s hardware components.

Control Unit. The heart of the PARTNER Plus system, the control unit consists of a backplane, cover (not shown), one processor module, plus up to four 206 modules. The backplane channels power to the system and connects the incoming telephone lines to the system.

Processor Module. The processor module contains the electronics that provide most of the system features. It also has audio and paging jacks.

Page Jack. The loudspeaker paging system plugs directly to this modular jack.

Music-On-Hold Jack. The audio source plugs directly into this RCA jack.

206 Module. Each 206 module has jacks for 2 incoming telephone lines and 6 extensions. The system can have up

to four 206 modules.

Line Jacks. Outside telephone lines connect to the top 2 jacks on each 206 module.

Extension Jacks. Telephones and other telecommunica- tions equipment connect to the bottom 6 jacks on the 206

modules.

AC Power. An ordinary 110 VAC grounded wall outlet (not controlled by an on/off switch) supplies power to the control unit.

Network Interface Jacks. Incoming telephone lines service the system through these jacks. These lines can be from the local telephone company or another system, such as a PBX (Private Branch Exchange) or Centrex.

PARTNER Display Phone: Extension 10. The system operator in this example is the receptionist on extension 10 and has a PARTNER display phone. This phone can handle 8 outside lines and has a display showing the time, number dialed, duration of call, and programming messages. Also, its programmable buttons (two with lights) can be programmed to store additional features and Auto Dial numbers. Because the display is required for system

programming, extension 10 on your system must also have an PARTNER display phone.

Standard Touch-Tone Telephone Used as a Power FailureTeIephone. In a power failure, the first extension jack on each 206 module connects to the first outside line on that module to provide continuous service to standard non-PARTNER telephones. In this example system, the PARTNER phone on extension 10 will not work during a power failure. However, the receptionist can use the standard touch-tone phone connected to extension 10 to place and receive calls on line 1.

AT&T 267F2 Bridging Adapter. This adapter com- bines the standard touch-tone phone and the PARTNER display phone on one extension jack. The adapter has two modular jacks, one for each phone. You can use the bridging adapter to combine any two devices (PARTNER telephones, industry-standard telephones, or other equip- ment) on one extension jack as long as the total Ringer Equivalence Number on each extension jack is 2 or less. (A device’s Ringer Equivalence Number—REN--is shown on its UL label.) The bridging adapter plugs into a wall jack or directly into an extension jack on the 206 module.

PARTNER 12-Button Phone. This phone is Iike the PARTNER display phone, but it has no display.

PARTNER 6-Button Phone and Answering Machine. Using a 267F2 bridging adapter, both a PARTNER 6-button phone and an answering machine are connected to one extension. The PARTNER 6-button phone accommodates up to 4 outside lines.

Industry-Standard Telephone. A standard single-linetouch-tone phone (such as you might have in your home) is connected directly to the extension jack.

Doorphone. A doorphone is installed at the entrance. When someone at the entrance presses the button on the doorphone, up to 5 designated telephones in the office ring automatically.

Bell. A loud bell connected directly to the extension jack rings when the extension is called.

Fax Machine and Standard Telephone.A fax machine and standard touch-tone phone are connected together on an extension jack. This setup lets you share the fax line with a telephone. If you pick up the phone and hear a fax signal, you can simply hang up to let the fax machine receive the call.

Alternatively, you can use a PARTNER phone at another extension to monitor the fax machine (“Fax Management”). To do so, first use System Programming to identify the fax machine extension. Then program a lighted button on a PARTNER phone with the fax extension number as an Auto Dial number. You can then use the Auto Dial number to quickly transfer calls from that extension to the fax machine.

In addition, the light on that button shows whether the fax machine is in use, busy, returning a call you transferred to it, or not answering calls. If your AT&T fax machine includes the “Notify” feature, the fax machine can also notify you when a fax has been received.

Modem. A modem connected directly to an extension jack provides data communications capability to the personal computer.

Loudspeaker Paging System. A paging system is connected to the modular PAGE jack on the processor module. The PARTNER Plus system is compatible with AT&T’s paging systems.

Music-On-Hold Source. AT&T’s MAGIC-ON-HOLD®

cassette deck is connected to the RCA jack on the proces- sor module to provide customized music and messages for callers on hold. For information on MAGIC-ON-HOLD, call your AT&T representative or the AT&T Sourcebook at

1 800 451-2100. You can connect any type of audio equipment to your system (including a CD player, casette player, stereo receiver, etc.), but you must supply an audio cord with an RCA plug.

NOTE: Users of equipment that rebroadcasts copyrighted music or other material may be required to obtain a license from a third party such as ASCAP or BMI.
