Isdn Telephones (7500S & 8500S) - Avaya Communication Manager Administrator's Manual

ISDN telephones (7500s & 8500s)
The Integrated Services Digital Network (ISDN) telephones include both the 7500-series and
the 8500-series telephones. Each of these telephones uses the ISDN communications through
a 4-wire "T"-interface.
National ISDN (NI-1 and NI-2) BRI telephones
Telephones that comply with National ISDN (NI-1 and NI-2) BRI standards can serve as
telephones on a Communication Manager system if they are programmed in Call Appearance
Call Handling - Electronic Key Telephone Service (CACH-EKTS) mode. Examples of NI-BRI
telephones that are supported are:
Nortel 5317T
●
L3 STE
●
6210 and 6220 Tone Commander
●
NI-BRI telephones with Communication Manager offer multiple call appearances, the
Conference, Transfer, Hold, and Drop feature buttons, and a Message Waiting Indicator.
NI-BRI telephone users must access all other features of Communication Manager using
feature access codes. Additional feature buttons on an NI-BRI telephone can be assigned only
as call appearances, and the number of call appearance buttons administered in
Communication Manager must match the number of call appearances administered on the
telephone. Bridged call appearances are not supported.
NI-BRI telephones also have access to all features of the Multi-level Precedence and
Preemption (MLPP) capability if MLPP has been enabled.
7505D ISDN-BRI telephone
The 7505D telephone serves as a telephone if it is equipped with a Voice Only Module (VOM).
As a telephone, it offers programmable buttons, fixed feature buttons, a Message light,
touch-tone dialing, and a built-in, programmable speakerphone or SPOKESMAN loudspeaker.
The 7505 can be equipped with an optional Asynchronous Data Module (ADM) that provides
the user with simultaneous voice and data capabilities. The 7505 equipped with the ADM offers
the same voice capabilities as the 7505 equipped with the VOM, plus it allows you to attach
data terminals or personal computers to send and receive data through the digital network.
