This portable, cordless telephone is designed to help you use the many features of the
AT&T DEFINITYCommunications System Generic 1, Generic 2, and Generic 3,
System 75, and System 85.
In order to provide you with the freedom of mobility, the MDC 9000 is not connected
physically (by a line cord or wire from the handset) to the DEFINITY system (or
System 75 or System 85). Instead, the MDC 9000 handset communicates by way of a
radio link to its radio base, which connects to the telephone system.
See Figure 1 to view the handset and Figure 2 to see its charging base. Then read
the explanations of this telephone’s many features following the figures.

What the Features Do
The following section lists the many voice features that you can use with your MDC
9000 and briefly explains what each one does and how you might want to use it.
The features in this guide have been divided into two categories:
d Phone Features — Those telephone features that you can use immediately
regardless of which communications system your telephone is behind.
d System Features — Those features that you can use only with a DEFINITY
Communications System or System 75 or System 85. Some system features may
not be available for all system types. If a feature is not supported by all systems,
the systems that do support that feature are identified in this document by
boldface type for the system name. Most of the system features must be
assigned to your telephone by the system manager. Check with your system
manager to see which of these features you can use.
b b
ffffffffffffffffffffffffffffffffffffffffffffff
Phone Features
The following features can be used immediately. They do not need to be
administered on your telephone.
Conference Allows you to include up to five parties, including yourself (with a
DEFINITY G1 or G3 or System 75), or three parties, including yourself (with
DEFINITY G2 or System 85) on a conference call, without losing voice quality.
Note: If you have both an active call and a call on hold, you must terminate one of
them before you can use Conference.
Display Information Provides visual call and telephone status information through
the following set of icons:
dcbbbc
bbb
or
cbbbc
bbb
or
cbbbc
bb b
shows the status of the adjacent button. If the triangle and
rectangle both appear, you are using that line; if only the rectangle appears, the
line is in use.
d ON appears when the handset is on.
d RANGE flashes to indicate that you are out of range and appears steadily when
you have lost communication.
d P is not used with DEFINITY or System 75 or System 85.
d STAT appears when the status mode is active, refreshing the icons and
indicating that you should move closer to the base.
d MSG appears when there is a message waiting for you.
6

d BATT appears when the battery is low.
Drop Allows you to disconnect any call or drop the last person you added to a
conference call. [The (unlabeled) Drop button is located in the lower right corner of
the LCD display.]
Hold Puts a call on hold until you can return to it. While a call is on hold, you can
leave your telephone to perform another task or pick up a call on another call
appearance.
Out-of-Range Indication While the set is still active, it gives an audible indication
(double beep) and visual indication (the RANGE icon appears on the LCD display)
when the handset is getting out of range.
Status Lets you know if your telephone is within working range. If you press the
Status button while the handset is out of range, a loud double beep is sounded and
the RANGE icon appears. These Status responses do not respond in-range and/or
off-hook.
Test (Local Test) Allows you to verify the operation of the audio and visual
warning signals.
Transfer Transfers a call from your telephone to another extension or outside
number. Use when your caller needs to speak further with someone else.
Note: Calls from an outside number to your telephone can be transferred only to an
extension, not to another outside number.
b b
ffffffffffffffffffffffffffffffffffffffffffffff
System Features
These features must be administered for your telephone by the system manager.
Check with your system manager to see which features you can use.
Abbreviated Dialing Allows you to store selected number groups for quick and easy
dialing of frequently called, lengthy, or emergency numbers. Any number group can
be a complete or partial telephone number, an extension number, a trunk, or a
feature access code. There are four possible types of lists—personal, group, system,
and enhanced—and you can use as many as three out of these four (see your system
manager for details). Numbers on a personal list are programmable by you; numbers
on all other lists are programmable only by the system manager.
Automatic Callback Sends you a special 3-burst ringing tone indicating that a
previously busy or unanswered extension is now available. Use to avoid constant
redialing when you want to speak to someone who is frequently busy on the
telephone or in and out of the office.
Note: Can be used only for extensions, not outside numbers. If your telephone is
connected to DEFINITY G2 or System 85, the Automatic Callback feature works
only with extensions that were busy; that is, it does not work with extensions at
which the person did not answer.
7

Call Forwarding All Calls This Call Forwarding feature is for DEFINITY G1 and
G3 and System 75 only. See ‘‘Call Forwarding — Busy/Don’t Answer’’ and ‘‘Call
Forwarding — Follow Me’’ for the DEFINITY G2 and System 85 Call Forwarding
features. Temporarily forwards all your calls to another extension or to an outside
number, depending on your system. Use when you will be away from your telephone
and you want your calls forwarded to a telephone of your choice.
Call Forwarding — Busy/Don´t Answer This is a DEFINITY G2 and System 85
feature only. See ‘‘Call Forwarding All Calls’’ for DEFINITY G1 and G3 and
System 75 call forwarding. Temporarily forwards all your calls to another
extension or to the attendant if your voice terminal is busy or you do not answer your
calls within a preset number of rings. Use when you want your calls forwarded to a
telephone number of your choice.
Call Forwarding — Follow Me This is a DEFINITY G2 and System 85 feature
only. See ‘‘Call Forwarding All Calls’’ for DEFINITY G1 and G3 and System 75
call forwarding. Temporarily forwards all your calls to another extension or to an
outside number, depending on your system. Use when you want your calls to be
automatically forwarded to a telephone number of your choice.
Call Park Puts a call on hold at your telephone, for retrieval at any extension. Use
when you need to go elsewhere to get information during a call, or whenever you
want to complete a call from a different location. Also, if the call received is for
someone else, use it to hold the call until the called party can answer it from the
nearest available telephone.
b b
Call Pickup Lets you answer a call at your telephone for another extension in your
pickup group. Use when you want to handle a call for a group member who is absent
or otherwise unable to answer.
Note: You can only use this feature if you and the called party have been assigned
to the same pickup group by your system manager.
Consult This feature is for DEFINITY G1 and G3 and System 75 only. Allows
you to screen calls for another party in your local calling group.
Intercom Allows you to communicate with other local telephones via an intercom
feature.
Leave Word Calling Leaves a message for another extension to return your call.
The called party is able to dial a message service (for example, attendant, AUDIX,
covering user, etc.) to retrieve a short, standard message which gives your name and
extension, the date and time you called, and the number of times you called. Use
any time you want to have someone call you back while helping cut down on repeated
call attempts.
Priority Calling Allows you to call another extension with a distinctive 3-burst ring
to indicate that your call requires immediate attention. Use when you have
important or timely information for someone.
