1. A communication gateway for protocol translation, comprising:

  • a Signaling System No. 7 (SS7) Module for receiving a plurality of incoming SS7 queries and sending a plurality of responses corresponding to said incoming SS7 queries, comprising;

    a front end processor (FEP) for stripping a SS7 Message Transfer Part (MTP) layer and a SS7 Signaling Connection Control Part (SCCP) layer from each of said incoming SS7 queries to thereby obtain a SS7 Transaction Capabilities Application Part (TCAP) message, for parsing said SS7 TCAP message into a Transaction portion and a Component portion, for attaching said Transaction portion to said Component portion to thereby obtain said SS7 TCAP message for each of said responses corresponding to said incoming SS7 queries, and for attaching said SS7 MTP layer and said SS7 SCCP layer to said responses; and

    an Inbound Subsystem Module, coupled to said SS7 Module, for translating said incoming SS7 queries from a SS7 protocol to a non-SS7 protocol, said translated incoming SS7 queries being forwarded to an end user while in said non-SS7 protocol, and for translating said responses corresponding to said incoming SS7 queries from said non-SS7 protocol to said SS7 protocol.
