22.6.5 Create a Bearer Capability Routing Table
The bearer capability table is used to route calls based on the bearer capability field in the ISDN
setup message. This can be used to differentiate between ISDN data services and ISDN speech
connections.
Note:
Terminals connected to analogue extensions (e.g. of a PBX) do not supply bearer capability
values in their call set-up. It is therefore up to the configuration of the analogue port on the Terminal
Adapter, NT or PBX to insert this value. The configuration of this value is however often omitted or
wrong. The BC value may therefore not be a reliable indication to differentiate between analogue
speech, audio or Fax Group 3 connections.
The Session Router can route calls according to the following bearer capabilities:
•
ItcAudio31:
Transparent 3.1kHz channel
•
ItcSpeech:
Voice terminals (Telephones)
•
ItcUD64:
Unrestricted digital information (64kBit/s)
•
ItcRD64:
Restricted digital information (64kBit/s)
