ABSTRACT:
A message interceptor is interposed in a link of a communications signalling network such as an SS7 network. The interceptor separately maintains the link level protocols on the two portions of the link with which it interfaces. Message data is transferred across between the link portions by a transfer circuit of the interceptor. In the course of this transfer, the nature of the data is checked by a selective action control circuit against selection criteria held in a store. If a selection criteria is met, the control circuit acts to suppress or modify the data.
