Control Unit

Hardware

The PARTNER Plus system’s modular hardware design makes it easy to install and expand. The main system component is the control unit, to which you connect telephones and other equipment.

The control unit includes:

■Processor Module. The processor module contains the software that controls the system’s features. It also has two jacks for connecting a loudspeaker paging system and an audio source for music on hold.

■206 Modules. Phone lines, phones, and other equipment connect to the modular jacks on 206 modules. Each module has jacks for 2 lines and 6 extensions. A system can have up to four 206 modules for a maximum of 8 lines and 24 extensions. The system requires at least one 206 module (purchased separately).

■Backplane. All the modules slide easily into the backplane, which channels power to the system.

■Cover. The cover slides onto the front of the backplane.

PARTNER TeIephones

AT&T manufactures three Multi-Line Series (MLS) telephones specifically designed to work with your PARTNER Plus system:

■Model MLS-12DTMfor up to 8 outside lines, has 12 buttons with dual lights, 6 buttons without lights, a built-in speaker and microphone, and a display. We refer to this phone as the PARTNER display phone.

■Model MLS-12™ is the same as model MLS-12D without the display. We refer to this phone as the PARTNER 12-button phone.

■Model MLS-6TMfor up to 4 outside lines, has 6 buttons with dual lights and a built-in speaker. We refer to this phone as the PARTNER 6-button phone.

The system can have any combination of these phones, but extension 10 must have a PARTNER display phone, for system programming.

Other Equipment

When connecting standard equipment to the PARTNER Plus system, the total ringer equivalence number (REN) of the device(s) connected to each 206 extension jack cannot exceed 2. The REN is listed on a label on the device.

The PARTNER PIUS system also works with industry-standard telecommunica- tions equipment. You can connect equipment such as standard, single-line touch-tone or rotary phones, fax and answering machines, modems, and door- phones to the system—without expensive adapters or additional phone lines.

You can connect a standard device to an extension jack by itself or combined with another device. For example, you can connect a phone and an answering machine to one extension by using an AT&T 267F2 bridging adapter (two included with each 206 module).
