What are the advantages of CCS over in-channel signalling?

The advantages of CCS over in-channel signalling are given below:

a. Information can be exchange among the processors much more quickly than while channel connected signaling is used.

b. Consequently, a much wider repertoire of signals can be used and it enables more services to be given to customers.

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

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

e. Because there is no line signaling, the junctions can be utilized for calls from B to A in addition to calls from A to B. Both methods working needs fewer circuit to carry the traffic than if divide groups of junctions are given from A to B and from B to A.

f. Signals relating to a call can be sent whereas the call is in progress. It enables customers to alter connections after they have been established.

g. Signals can be exchanged among processors for functions other than call processing, for illustration for maintenance or network management reasons.
