Data modules 

Refer to 

‘‘Generalized route selection’’ on page 1340

 for a detailed description of 

Bearer Capability Classes (BCC) and their ability to provide specialized routing 
for various types of voice and data calls. The BCC value is used to determine 
compatibility when non-ISDN-PRI facilities are connected to ISDN facilities 
(ISDN-PRI Interworking).

Assigns a 7500 Data Module. The 7500 data module supports 
automatic TEI, B-channel, maintenance and management 
messaging, and SPID initialization capabilities. BRI endpoints, 
both voice and/or data, are assigned to either the ISDN-BRI - 
4-wire S/T-NT Interface circuit pack or the ISDN-BRI - 2-wire 
U circuit pack. Each can support up to 12 ports. Since BRI 
provides multipoint capability, more than one ISDN endpoint 
(voice or data) can be administered on one port. For BRI, 
multipoint administration allows for telephones having SPID 
initialization capabilities, and can only be allowed if no 
endpoint administered on the same port is a fixed tie endpoint 
and no station on the same port has B-channel data capability. 
Currently, multipoint is restricted to 2 endpoints per port.

Assigns an announcement data module. The announcement 
data module is built-in to the integrated announcement circuit 
pack and is administered using the Announcement Data 
Module screen. This data module (in conjunction with an 
administered Netcon Data Module in G3si configurations) 
allows the system to save and restore the recorded 
announcements file between the announcement circuit pack 
and the system memory.
