Abstract: In a radio concentrator system formed by a central station and remote stations, demand-assigned data channels are constantly monitored to detect when they are congested. When an emergency call is received from a subscriber terminal, a dial tone is sent to the terminal if the emergency call occurs simultaneously with the detection of a congestion. On hearing the dial tone, the subscriber dials an emergency destination address, which is received by a remote station and compared with a list of predetermined addresses and verified if it matches one of the predetermined addresses. The dialed information is sent from that station to the central station, where it is relayed to a switched network. An emergency channel is established to the network for routing the emergency call.
