TELECOMMUNICATIONS SYSTEM

摘要

The invention comprises a telecommunications signalling processor (400) for processing Signalling System #7 (SS7) telecommunication signaling messages to select ATM virtual connections and provide control messages indicating the selected ATM virtual connections. The signaling processor comprises: a computer system, data structures, originating process logic, and terminating process logic. The data structure has trunk circuit table (500), trunk group table (502), exception table (504), ANI table (506), called number table (508), and a routing table (510). Originating process logic and terminating logic are stored in the computer system and process information from (SS7) signaling messages that relates to an originating circuit and terminating circuit and access the data structures to request a terminating ATM virtual connection in response to the request from the originating process.
