Q. What are the benefits of ccs over in-channel signalling?

The benefits of CCS over in-channel signalling are listed below:

a. Information can be exchange between processors much faster than when channel associated signaling is used.

b. Consequently a much wider repertoire of signals can be used and this enables more services to be provided to customers.

c. Signals can be added or changed by software modification to provide new services.

d. There is no longer any requirement for line signaling equipments on every junction that results in a considerable cost saving.

e. As there is no line signaling, junctions can be used for calls from B to A in addition to calls from A to B. Both ways working needs fewer circuit to carry the traffic than if separate groups of junctions are provided from A to B and from B to A.

f. Signals relating to a call can be sent when the call is in progress. This allows customers to alter connections after they have been set up.

g. Signals can be exchanged between processors for functions other than call processing, for instance for maintenance or network management purposes.
