A SYSTEM FOR CONNECTING CALLS ON PHYSICALLY DISTINCT SERVERS ON AN ADVANCED INTELLIGENT NETWORK

摘要

A bridge connection is made between interfaces on physically distinct telecommunication servers such that the two ends of the bridge can be used t o connect existing calls that are terminated on each of the servers. To provide the br idgeconnection, a call using a standard outgoing T1 trun k on one of the servers is made through the public switched telephone network (PSTN) to an incoming T1 trunk on the other server. The servers reserve a special directory number for such ca lls. When a bridge connection is required one of the servers is queried for its specia l directory number. The other server is then instructed to make a call to that number. W hen the called server recognizes the incoming call as using its special number, it a nswers the call. The calling server then outpulses information needed by the called ser ver to associate the bridge connection with the pending action. In this manner, cal ls terminating on distinct servers can be connected without the need for additi onalhardware.
