Patent ID: 7149815

Claim:
An integrated information communication system (ICS), wherein: an ICS network address for discriminating an ICS logic terminal is assigned to an ICS logic terminal of a terminal in a user communication line; when a set of ICS logic terminal discrimination information and a receiver ICS user address is decided, an ICS network communication line to transfer an ICS network frame between an access control apparatus at a sending side and an access control apparatus at a receiving side is uniquely decided; an ICS network address to decide a destination of the ICS network frame to specify the ICS network communication line is defined by said access control apparatus at the sending side, an external ICS user frame having a unique ICS user address system ADX is inputted to said access control apparatus at the sending side from the user communication line via the ICS logic terminal; when ICS logic terminal discrimination information is inputted by the ICS user frame, the sender ICS user address and the receiver ICS user address in the ICS user frame are found to be registered in a conversion table in said access control apparatus at the sending side; the ICS user frame is converted to an internal ICS network frame having an ICS network address system ADS; the ICS network frame includes a network control field which is operable to store at least the ICS network address to specify the ICS network communication line; a destination of the ICS network frame is judged, under a rule of the ICS network address system ADS, by said access control apparatus of the sending side, and the ICS network frame is then transferred in the ICS network communication line; and when the ICS network frame is reached at said access control apparatus at the receiving side, the ICS user frame is restored from the ICS network frame, is transferred in another user communication line via an ICS logic terminal of said access control apparatus at the receiving side, and is reached at an external information communication equipment.
