4、d envisage introducing Supplementary Services which have not been provided with existing networks because: (a) the control procedure were too cumbersome or, (b) the interruption of the call in progress in order to send control signals would have been unacceptable. An example of such a Supplementary
5、Service is Number Identification. Relevance of Supplementary Services That the operation of Supplementary Services should always be relevant to the form of trafic being carried. A matrix relating the relevance of Supplementary Services to Bearer Services and a matrix relating to Teleservices see T/S
