Q. Compare in-channel signalling with common channel signalling?
Network wide signalling also involves end to end signalling between originating exchange and the terminating exchange. Such a form of signalling is known as line signalling. CCS doesn't use the speech or the data path for signalling. It employs a separate common channel for passing control signals for a group of trunks or information.
In Channel
Common Channel
Trunks are held up during signalling.
Trunks aren't required for Signalling
Signal repertoire is limited.
Extensive signal repertoire is possible.
Interference between voice and Control signals may occur.
No interference as the two Channels are physically separate.
Separate signalling
Only one set of signalling
Equipment is needed for each trunk and thus expensive.
equipments is essential for a whole group of trunk Circuits and hence CCS is economical
Voice channel being the control channel, there is a possibility of potential misuse by the customers.
Control Channel is in general in accessible to users.
Signalling is comparatively slow.
Signalling is significantly fast.
It is difficult to change or add signals.
There is flexibility to change or add signals.
It is difficult to handle signalling during speech period.
Signals during speech. There is freedom to handle
Reliability of signalling path is not Critical.
Reliability of the signalling Path is critical.
Speech circuit reliability is assured.
There is no automatic test of speech circuit.
Common channel signalling is better than In-channel signalling.
