The ITU-T BICC protocol: the vital step toward an integrated voice-data multiservice platform

At the end of 1999, the ITU-T completed the first edition of the Bearer-Independent Call Control (BICC) protocol, just nine months after the start of this activity. The development of BICC can be considered historic. For the first time a full-fledged operator-grade PSTN/ISDN service can be offered over a variety of packet networks, using only standardized protocols. This tutorial explains the BICC architecture and the operation of the BICC protocol.
