A private communication network through which a plurality of member users communicate using the public switched telephone network (PSTN) (10) is disclosed herein. Each member user utilizes either a modified land line telephone (48) directly connected to PSTN (10), or uses a modified mobile telephone (22) operatively coupled to the PSTN through a wireless communication system (14). The private communication network includes network call manager (40) having a telephone network interface (92) for establishing a telephone connection with each of a plurality of telephone lines (44) of the PSTN (10). Each of the plurality of telephone lines (44) is associated with one of the plurality of member users. The network call manager (40) further included a switch matrix (110), coupled to the telephone network interface, for providing an information signal received from an active member user over a selected telephone line to the remaining non-active member users.

Réseau de communication privé à l'aide duquel de multiples utilisateurs peuvent correspondre au moyen du réseau téléphonique public commuté (RTPC) (10). Chaque utilisateur se sert soit d'un téléphone conventionnel modifié (48) raccordé directement au RTPC (10), soit d'un téléphone mobile modifié (22) couplé au RTPC par l'intermédiaire d'un système de communication sans fil (14). Le réseau de communication privé comprend un gestionnaire d'appels réseau (40) qui, à l'aide d'une interface (92) avec le réseau téléphonique, établit une liaison avec chacune des lignes (44) raccordées au RTPC (10), chaque ligne (44) correspondant à un utilisateur particulier. Le gestionnaire d'appels (40) met en jeu une matrice de commutation (110) qui, couplée à l'interface avec le réseau téléphonique, permet de fournir aux utilisateurs « passifs » le signal d'information émanant de l'utilisateur « actif » et transmis sur la ligne téléphonique sélectionnée.
