AT&T MLS-6TM, MLS-12DTM, MLS-12TM manual General Guidelines

General Guidelines

If you combine a standard phone and PARTNER phone on one extension, you may want to turn off the ringer of the standard phone during normal use.

Instructions for installing the control unit, telephones, and other equipment are on the following pages (figures 2-1to 2-3).Before you begin, please note the following guidelines:

Using the System Planner is essential for knowing where phones and other equipment are to be installed, and how the system and phones are to be programmed.

Install the control unit so that it meets the environmental and electrical requirements listed on p. 1-4.

If wall mounting the control unit, you will need four #12 screws appropriate for the type of wall and weight of the control unit.

When connecting wires to the jacks on a 206 module, leave at least 2 feet of slack for removing the module without first disconnecting the wires. If you later replace the module, you can remove the old module with the wires in place and plug them into the new module one at a time.

PARTNER phones require at least 2-pair wiring and are compatible with AT&T 4-pair PDS wiring.

Standard phones and other equipment require 1-pair mounting cords (AT&T D2R mounting cords recommended).

When connecting two devices to a single extension, use only an AT&T 267F2 bridging adapter.

Connect a PARTNER display phone to extension 10 for system programming.

Do not connect doorphones to extensions 10, 16, 22, or 28.

Do not install telephones out of the building.

A hotline phone must be a standard, single-line phone, not a PARTNER telephone. However, the hotline phone can ring any type of phone.

During a power outage, neither the system’s features nor PARTNER phones work. However, standard, single-line touch-tone or rotary phones connected to extensions 10, 16, 22, and/or 28 can be used to place and receive calls. These extensions connect directly to lines 1, 3, 5, and 7, respectively. To prepare for a power failure, AT&T recommends:

■Store standard phones close to extensions 10, 16, 22, and/or 28. During a power failure, replace the PARTNER phone with the standard phone. Or, connect a standard phone to these extensions at all times, either by itself or combined with an PARTNER phone via a 267F2 bridging adapter.

■Do not program a Hotline on extension 10, 16, 22, or 28 to keep these extensions available for power failure use.

If upgrading from a one-module PARTNER system, remove the rubber feet that may be attached to the 206 module before installing.

If upgrading from a two-module PARTNER system, remove the module connector from the the two modules.
