Instruction manual

MLS- and MLC-model telephones
The AT&T telephones that are specifically designed
for use with PARTNER systems. Models include the
MLS-34D, MLS-18D, MLS-12D, MLS-12, MLS-6, and
MLC-6 phones.
Music-on-hold system
Equipment that lets you play recorded music to
callers who are placed on hold. A music-on-hold
audio source can be connected to an RCA jack on
the primary processor module in the control unit.
N
Network interface jack
A jack, generally located in your equipment room,
that provides access to an outside line coming into
your building from your local telephone company.
A line cord from the network interface jack to a line
jack on a 206 or 400 module connects the line to
your system.
Night Service
A feature that lets you redirect calls received after
hours or when a receptionist is not available to
answer calls. (This feature also activates night
service operation of PARTNER MAIL.)
O
One-touch Intercom Calling button
See Intercom Auto Dial button.
Outside lines
See Line.
P
PARTNER Attendant
An optional call routing device that answers calls
and routes them to the appropriate extension based
on caller responses to a recorded announcement.
PARTNER MAIL
An optional call routing and messaging device that
provides call coverage by answering calls and
routing them to caller designated extensions. It also
lets callers leave messages at unanswered
extensions and lets subscribers retrieve their
messages.
Password
A four-digit code assigned by the system manager
that users can enter from MLS-model system
phones to override dialing restrictions and to turn
Night Service on and off. See also Night Service.
Pickup Group
A group of extensions for which calls to any
extension in the group can be picked up, from any
extension in the system, by dialing a group pickup
code.
Primary carrier
The required component of the AT&T control unit
that contains the primary processor module and
206 modules and 400 modules. See also Expansion
carrier.
Primary processor module
This AT&T module, which is always installed in the
center slot of the primary carrier, manages the
components of your control unit. See also
Expansion processor module.
Programmable button
A telephone button that does not have a line
assigned; it can be set up to dial a number or
access a feature. On MLS- and MLC-model
phones, programmable buttons can be used as
Auto Dial buttons (for one-touch dialing of intercom
or outside telephone numbers) or dial-code feature
buttons (for one-touch dialing of feature codes).
Programming
See System Programming and Extension
Programming.
Programming extension
An extension from which you can program the
system; this can be either extension 10 or 11.
Proprietary device
A telephone or other device that is designed to work
with a specific system, and requires a special
interface to connect to the public telephone
network. For example, MLS- and MLC-model
telephones are proprietary devices that can only be
used with the control unit described in this guide.
See also Industry-standard device.
R
Recall
A system feature that sends a timed switchhook
flash to let you “recall” a dial tone to make another
call or to access a PBX or Centrex service. (Use
Recall only on an outside call; using Recall on an
intercom call disconnects the call.)
