analog multiline telephone. Single-line telephones and analog cordless or
wireless 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 3
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 for 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 example,
for tie trunks connecting private-networked systems (Release 6.0 and later
systems, Hybrid/PBX mode)
.
When you make a change to your system, consult
your Lucent Technologies representative for information about additional TTRs
that may be required.
016 (T/R), 012, and 008 OPT Modules 3
Extension modules that support single-line telephones or off-premises telephones
(OPTs) must have ring generators so that the telephones get electrical current for
their ringers. All 016 (T/R) extension modules, which are compatible only with
Release 4.0 and later systems, include built-in ring generators. Since late 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 (T/R), 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. For more information, see “Adjuncts” on page 3–36
.
NOTE:
The MERLIN LEGEND Mail
®
Voice Messaging System integrates a T/R
module (007 MLM) with a voice messaging system and is both a module
and an application.
