METHOD AND SYSTEM FOR THE EXCHANGE OF SIGNALS IN A COMMUNICATIONS NETWORK.

摘要

The invention relates to a communication system (110) and a method for the exchange of signals between a public telecommunication network (20) and at least one communication arrangement (100) via the communication system (110). The communication system comprises a network adapter unit (60) comprising a first signal port (65) which is connectable to the public telecommunication network (20) and a second signal port (340). It further comprises at least one subscriber adapter unit (70) comprising a third signal port for the exchange of signals with the second signal port, and a fourth signal port which is connectable to the communication arrangement (100). The subscriber adapter unit (70) is arranged to initiate a communication session in response to a connection signal. The network adapter unit (60) is arranged to produce a completion message at the network adapter unit (60) in response to reception, on the first signal port (65), of a disconnection signal from the public telecommunication network (20).
