ABSTRACT:
A telecommunications system receives a call back request though a separately maintained computer network, such as an X.25 based computer network, and initiates the actual call back toward the requesting subscriber using its own Signaling System No. 7 (SS7) telecommunications network. If the call back request fails, an X.25 packet containing an error code is transmitted back to the originating subscriber over the separately maintained computer network. An X.25<=>TCAP converter is used as an interface card to allow X.25 packets to communicate freely with TCAP based telecommunications network.
