Telecommunication network comprising a plurality of stacked private networks, private automatic branch exchange for implementing said network, and emergency call center
First Claim
1. Telecommunication network including a plurality of company networks (PN11, PN21) having respective independent numbering plans characterized in that it includes at least one company network (P11) having at least one first private automatic branch exchange (PBX11c, . . . ) including a first gateway providing inter alia number translation and at least one other company network (P21) having at least one second private automatic branch exchange (PBX21a) including a second gateway providing inter alia number translation, in that these two gateways are connected by a line (T4, T5), and in that these two gateways and this line (T4, T5) are capable of transporting signaling specific to company networks.

Abstract
This telecommunication network includes a plurality of private networks (PN11, PN21) which are stacked on at least two levels (L1, L2), each private network (PN11) comprising at least one private automatic branch exchange (PBX11a, PBX11b, PBX11c). At a first level (L1), at least one private network (P11) has at least one first private automatic branch exchange (PBX11c, . . . ) which is connected to a second private automatic branch exchange (PBX21a) of a private network (PN21) belonging to a second level by a line (T4, T5) that can transport the signaling of a private network. This second private automatic branch exchange (PBX21a) is configured with data and routing rules which authorize access to at least one service offered by the second network (PN21) by the first private automatic branch exchange (PBX11c). The two private automatic branch exchanges, which are at the two ends of a line (T4, T5), include software means forming a gateway for number translation, to remedy the fact that the numbering plans of the networks are independent of each other. Moreover, the gateways and the line can transport specific signaling for company networks.
