Abstract :
The core network is based on the separation of functionality in the control layer, connectivity layer, and application layer. The BICC signaling is carried on top of either the ATM or IP based signaling transport using a signaling transport converter, which makes the call control signaling independent on the underlying layers. BICC CS2 protocol versions are enhanced with a new set of capabilities in comparison with the earlier BICC CSI version. This article has shown that the new version of BICC protocol should not exclude the earlier BICC protocol. Operators have been given the possibility for smooth migration from the telephony over ATM (ToATM) towards ToIP using BICC as a call control protocol.
