摘要： A radio access system connects a public switched telephone network and a subscriber unit. The subscriber unit includes a first detection part detecting a telematique signal; and a first control part transmitting a detection signal of the telematique signal on a control channel and transmitting the telematique signal on a traffic channel while bypassing a first speech coding-and-decoding part. The radio access system includes a second control part, provided between a radio base station and the public switched telephone network, transmitting the telematique signal on the traffic channel toward the public switched telephone network while bypassing a second speech coding-and-decoding part when the detection signal of the telematique signal is transmitted on the control channel.

摘要： A redundant monitoring control system includes at least one monitored control apparatus forming a communication network, and a plurality of monitoring control apparatuses monitoring and controlling the monitored control apparatus. The monitored control apparatus switches a monitoring and control of the monitored control apparatus by a monitoring control apparatus of a working system to a monitoring control apparatus of a backup system in response to a disconnection from the monitoring control apparatus of the working system which is detected when the monitoring control apparatus of the working system fails. The monitoring control apparatus of the backup system recognizes a control operation carried out by the monitoring control apparatus of the working system until the switching, and carries out a remainder of the recognized control operation with respect to the monitored control apparatus.
