analog multiline telephone and a modem or other adjunct at the same location in the system and give each one its own extension number, you must use two physical extension jacks on the module.

The Voice Announce to Busy feature, which allows a telephone user to hear a voice page (also called a voice-announced call) while on another call, has the same requirements as an adjunct that operates independently from the phone: one extension jack (and no adjunct) for an MLX phone; two extension jacks for an analog multiline telephone. Single-line telephones and cordless or wireless telephones (which are analog multiline telephones) cannot receive voice pages.

NOTE:

There is a distinction between an extension jack (sometimes referred to as a logical ID or port) and an extension number. In system programming, you sometimes need to use port/jack/logical ID numbers rather than extension numbers or system line/trunk numbers. Port/jack/logical IDs are numbered, starting at 1, from the bottom of a module, and are fixed: they cannot be changed. The extension and line/trunk numbers that people in the system dial are flexible and can be programmed.

Touch-Tone Receivers

In addition to jacks for connecting lines/trunks and extensions, various modules also include components called touch-tone receivers (TTRs). These TTRs allow the system to process touch tones entered by outside callers for special purposes, such as automated attendants that answer calls from people with touch-tone phones, voice mail systems, and remote access callers who call into the system and use its services. When your Lucent Technologies representative helps plan your system, he or she makes sure that your modules have enough touch-tone receivers to support your needs. When you add an application or adjunct to your system, you sometimes have to make more TTRs available as well. For information about adding TTRs, see the Equipment and Operations Reference (last updated for Release 3.0).

016, 012, and 008 OPT Modules

Extension modules that support single-line telephones or off-premises telephones (OPTs) must have ring generators so that the phones get electrical current for their ringers. All 016 extension modules, which are compatible only with Release

4.0and later systems, include built-in ring generators. Since late in 1993, 012 and 008 modules have come with ring generators built in. Earlier modules required Lucent Technologies technicians to install ring generators. If your 008 or 012 module has a ring generator, either added or built-in, you should see a label on the front of the module telling you that the ring generator is included.

Also, 016, 012, and 008 modules allow the connection of T/R devices directly to the control unit, without the need for a telephone and adapter at an extension. You can use them to hook up fax machines or PCs with modems, for example.
