What Is The Signalling And What Is The Difference Between Cas And Css?

Answer»

Signalling is a way of information exchange to ESTABLISHMENT and control of a TELECOMMUNICATION circuit and the management of the network.

Common channel signalling (CAS) uses a dedicated channel for the signalling where Channel Associated Signalling (CAS) conveys signalling information relating to multiple BEARER channels. These bearer channels therefore have their signalling channel in common.

CCS with E1 =30 B channels and 1 D channel
CCS with T1 = 23 B channels and 1 D channel
CAS with E1 = 31 B Channels
CAS with T1 = 24 B Channels
B=Bearer channels responsible for carrying voice signal
D=Data channel responsible for signalling control
