System Phones
This guide refers to AT&T telephones specifically designed to work with the
system as system phones. These include the PARTNER-18D, PARTNER-18,
PARTNER-6, MDC 9000, and MDW 9000 telephones. You also can use
MLS-18D®, MLS-12D®, MLS-12®, and MLS-6® system phones, although they
are not discussed in this guide. If you use MLS-model phones with the system,
refer to the documentation that shipped with those phones for information
specific to the MLS-model phones.
System phones have several buttons in common: four line buttons, two intercom
buttons, volume control buttons, and the [
Feature
], [
Conf
], [
Transfr
], and [
Hold
] buttons.
The PARTNER-18D and PARTNER-18 phones have four calling feature buttons
(to access the Privacy, Last Number Redial, Recall, and Conference Drop
features with the touch of one button) and eight Auto Dial buttons, on which
frequently-used outside phone numbers or extension numbers can be stored.
The PARTNER-18D phone has four buttons above the Auto Dial buttons; these
four buttons are operational only on the PARTNER
II
and PARTNER Plus
systems.
The PARTNER-18D also has a display; users receive messages and prompts
when making calls and changing system options. (More information about the
display is provided in Chapter 5.) Table 1-1 summarizes system phone features.
