well signalling is of 2 types. common channel signalling and channel associated signalling.
channel associated means wherein signalling happens as in the same E1s as the traffic medium.
common channel means wherein signalling and traffic are seperated.
common channel has advantages over the cas. some of them are a)no dedicated resources for signalling
b) we can dedicate resources based on traffic.
