ISDN telephones (7500s & 8500s)
The Integrated Services Digital Network (ISDN) phones include both the 7500-series and the 8500-series
telephones. Each of these phones uses the ISDN communications through a 4-wire "T"-interface.
National ISDN (NI-1 and NI-2) BRI telephones
Phones that comply with National ISDN (NI-1 and NI-2) BRI standards may serve as phones 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 phones that are supported are:
•
Nortel 5317T
•
L3 STE
•
6210 and 6220 Tone Commander
NI-BRI phones 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 phone may 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 phone. Bridged call appearances are not supported.
NI-BRI phones also have access to all features of the Multi-level Precedence and Preemption (MLPP)
capability if MLPP has been enabled.
