Bearer Independent Call Control (BICC)

This Recommendation describes the adaptation of the narrow-band ISDN User Part (ISUP) for the support of narrow-band ISDN services independent of the bearer technology and signalling message transport technology used.


ITU-T Recommendation Q.1901 was prepared by ITU-T Study Group 11 (1997-2000) and approved under the WTSC Resolution 1 procedure on 15 June 2000.

Capture Filter

You cannot directly filter BICC packets while capturing. However, in case BICC runs over SCTP/M3UA/MTP3 you could filter SCTP traffic using IP proto 0x84:

 ip proto 0x84 

or, in newer versions of libpcap:

 ip proto sctp
