Summary

This Recommendation specifies procedures in order to provide interaction between the Bearer Independent Call Control (BICC) and INAP CS-4, i.e. to support IN services in an ISDN environment.

It also specifies ISUP/INAP CS-4 interaction procedures as exceptions to BICC/INAP interaction procedures (see Annex B).

The interaction between other signalling systems and INAP can be found by consulting the relevant interworking Recommendation to the BICC in combination with the BICC/INAP interaction Recommendation.
