AT&T System 85 Telephone User Manual


 
GENERAL INFORMATION
Facilities Common to All Voice Terminals
Every DEFINITY G1, G2, G3, System 75, and System 85 voice terminal has the following equip-
ment:
A pushbutton pad for touch-tone dialing (except for the Model 500, which has a rotary
dial)
A handset with a coiled modular cord
A 7-foot modular mounting cord (except for the Model 2554 wall set).
Buttons
All multi-appearance voice terminals and most single-line terminals have buttons for handling
calls and activating various functions that enhance basic calling.
Fixed Feature Buttons
Buttons that are factory labeled and require no administration are referred to as fixed feature but-
tons. The following buttons, in several combinations, are found on most voice terminals. They
are dedicated to standard calling functions and are located adjacent to or above the pushbutton
dial pad for calling convenience.
Note: Fixed feature buttons that are limited to a small number of terminals are explained in
the detailed descriptions of those terminals.
Recall Button (on older sets)—provides a timed flash that is more accurate than a
manual switchhook flash and prevents accidental dropping of calls. The following list of
uses for this button is only valid for single-line terminals:
Put an active call on hold and obtain recall dial tone for making another call.
Disconnect from a second call and return to a call on hold, when pressed twice.
Place an active call on hold and answer a waiting call using Dial Access Code,
then toggle between the two calls (using the Recall button and Dial Access
Code).
Place an active call on hold; receive recall dial tone, and dial the Feature Access
Code to answer a waiting call. Toggle between the two calls by performing the
same action.
Add a party, previously put on hold, to a conference with a third party.
Drop the party previously added.
Disconnect Button (on older sets)—allows the terminal user, after completing one call, to
permanently disconnect from the call and get dial tone for placing a new call without
going on- and off-hook. On System 85 and DEFINITY G2, depending on the administra-
tion, this button can be used to reconnect to the call on hold on multiple appearance
voice terminals.
