Abstract:
1. A zone-specific controller (GK) of a communication system (SYS) including in each of a plurality of geographically distant zones (ZA, ZB, ZC) a different zone-specific controller (GK) and one or more subscriber terminals (EP) connected to each other via a zone-specific bus network (BUS-A, BUS-D, BUS-C), said zone-specific bus networks being connected to each other via at least one interconnection network (WAN), wherein said zone-specific controller (GK) controls the signaling traffic between the subscriber terminals (EP) in each zone and between different zones and comprises: a) a controller characteristics memory (CCM) for storing at least a private network identifier (PNID) of a private network (PN) to which said zone-specific controller (GK) and its connected subscriber terminals (EP) belong; b) a private network configuration memory (PNCM) for storing the private network configuration at least of the private network identified by the stored private network identifier (PNID); c) a private network configuration determining means (PNDM) for communicating (GRQ, GCF, GRJ) with all other controllers (GK) of the communication system (SYS) to determine the private network configuration including those controllers (GK) and subscriber stations (EP) in other zones (B, C) which belong to the private network (PN) identified by the stored private network identifier (PNID) and to store corresponding private network configuration information (TA; RA; CNCT) in said private network configuration memory (PNCM).
