Patent

CA 2160467

A telecommunications system comprises a public network and one or mole private networks each comprising a plurality of private exchanges (PBX's) (14) coupled to the public network. Signal mapping from PBX to public format and inverse mapping from public to PBX format provides transparent signalling of PBX calls across the public network. This avoids the use of dedicated private lines from the private network.

L'organisation des signaux pour passer du format privé à un format public et pour effectuer l'opération inverse, permet un transfert transparent des signaux entre le réseau privé et le réseau public. Ceci évite l'utilisation de lignes spécialisées partant du réseau privé.
