System Telephones
This guide refers to AT&T telephones specifically designed to work with the
PARTNER
II system as system phones. These include the MLS-34D, MLS-18D,
MLS-12D, MLS-12, MLS-6, and MLC-6 model telephones.
System phones have several buttons in common: volume control buttons, and
the [
Feature ], [ Conf ], [ Transfer ], and [ Hold ] buttons. In addition, each phone has
programmable buttons that can be used for outside lines, extension numbers,
outside phone numbers, or system feature codes. Outside lines, as well as
some system features, require buttons with status lights. Programmable buttons
without lines assigned to them can be programmed with numbers or features, so
you can use the feature or dial the phone number with one touch. The number
in each model name indicates the number of programmable buttons with status
lights plus two [
Intercom ] buttons. Table 1-1 summarizes system phone features.
If the phone has a display, indicated by a “D” in the model name, users will
receive messages and prompts when making calls and programming. (More
information about the display is provided in Chapter 5.) A system display phone
is required for system programming. It must be as large as the largest phone in
the system, since an MLS-12D or MLS-18D cannot program an MLS-34D.
Similarly, an MLS-12D cannot program an MLS-18D.

Intercom Autodialers
The system telephones at extensions 10 and 11 support up to two MLS-CA24
Call Assistant™ Intercom Autodialers, which allow you to program Auto Dial
buttons for all of the extensions in your system (up to 48). The Auto Dial buttons
allow the autodialer users to dial, signal, and transfer calls to programmed
extensions with one touch. The lights for the buttons also indicate calling
activity at programmed extensions. Each autodialer has 24 buttons that are
factory-set for intercom ringing system extensions; however, they can be
reprogrammed for intercom paging or manual signaling. For more information,
see “Auto Dialing” and “Manual Signaling” in Chapter 5.
