6400-Series Telephones - Avaya Communication Manager Administrator's Manual

6400-series telephones

The 6400-series telephones are DCP 2-wire telephones that work with Avaya Communication
Manager. The last two digits of the 6400-series model number identify the number of call
appearances (2-lamp buttons) for that model. For example, the 6424D has 24 call appearances.
The 6400 series includes two single-line sets (6402 and 6402D), 8-button sets, a 16-button set,
a 24-button set, and a 24-button expansion module (for the 6416D+ and 6424D+ telephones).
Each of the 6400-series telephones includes 6 standard feature buttons:
SPEAKER button, which can access a 2-way speakerphone or allow group listen
●
MUTE button, which mutes the handset or speakerphone microphone
●
HOLD button
●
REDIAL button
●
TRANSFER/TEST button for transferring a call or testing the lights and display on the
●
telephone
CONF/RING button for setting up a conference call and for selecting a personalized
●
ringing pattern.
These telephones do not have a standard Drop button, but you can assign a drop button to any
feature button. The 6400-series display telephones show the date and time in Normal mode, so
you do not have to assign a Date/Time button to these telephones.
6402/6402D telephones
The 6402 is a single-line telephone with six fixed feature buttons, a listen-only Speaker button, a
Feature button that allows you to use the dial pad keys for up to 12 features assigned by the
system manager, a red Hold button, a Redial button, a Transfer button that can also be used for
the Test feature, and a Conference button that can also be used to select a personalized ringing
pattern, a red Message light, and a Volume control button.
The 6402D is the same as a 6402, but also has a 2-line by 16-character LCD display.
The 6402 and 6402D can be used in a 2-wire environment only.
