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
