Abstract
A communication system and a method exchange signals between a public telecommunication network and at least one communication arrangement via the communication system. The communication system comprises a network adapter unit comprising a first signal port which is connectable to the public telecommunication network and a second signal port. The communication further comprises at least one subscriber adapter unit 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. The subscriber adapter unit is arranged to initiate a communication session in response to a connection signal. The network adapter unit is arranged to produce a completion message at the network adapter unit in response to reception, on the first signal port, of a disconnection signal from the public telecommunication network.
