Abstract

Abstract A method of producing interoffice signalling comprising storing program blocks for commanding generation, in a plurality of signalling protocols, of signalling signals in a communication switching system, storing correlations of particular ones of the program blocks with a particular protocol for signalling functions related to the process of a call to or from the communication switching system, enabling operation of the particular ones of the program blocks when a particular signalling signal is to be generated in the processing of a telephone call to or from the communication switching system, to match the particular protocol, whereby the communication switching system is enable to process calls restricted to the particular protocol out of the plurality of protocols for a particular call.
