What is BICC?

BICC provides a means of supporting narrowband ISDNservices across a broadband backbone network without

impacting the interfaces to the existing N-ISDN network

and end-to-end services.

The BICC call control signaling protocol is based on N-ISUP signaling

The bearer control signaling protocols are based on

different bearer technology control signaling protocols

(e.g., DSS2 for AAL type 1 and AAL type 2)

The BICC call control signaling protocol should not be

aware of the actual bearer transport being employed.

The binding information is used to reference the bearer.

BICC Capability Set 1

Forward and Backward Backbone Network

Establishment

Transport Call Control via MTP SS7 or ATM

Support of most existing narrow band services. New Backbone Network Connection (BNC) with or

without Codec Negotiation

Reuse of Idle Backbone Network Connection (BNC) Separate Release of Call and Backbone Network

Connection (BNC)

Bearer Transport Types supported: AAL 1 & AAL 2
