ISDN Service
The SBX IP 320 system does not support Basic Rate Interface (BRI) Integrated Services Digital
Network (ISDN) circuits. The BRI provides two bearer channels and one data channel (2B+D),
but for the Calling Line ID function, the same admin fields are used as ISDN.
Calling Number and Called Number services are supported. Calling Number services will be
routed in the same way as ANI (automatic number identification) calls using the DID route
table.
The rules and conditions of ANI are the same, and still apply to Calling Number service on
ISDN lines. Called Number services will be routed using the DID route table. The rules and
conditions of DID and still apply to ISDN Called Number service on ISDN lines.
•
The bearer channels (B channels) transport voice information to and from the Central
Office.
•
The data channel (D channel) controls all signaling information for the bearer channels.
