Abstract

The transmission system has an exchange terminating unit (COT) which can be connected to an exchange unit (EX) and is connected to a plurality of remote stations (RT1...RT3) via two optical, parallel-arranged lines (RL1, RL2). In the exchange terminating unit (COT), an incoming optical connection (RL1) is led to the further, outgoing optical line (RL2) in such a way as to form a folded ring network (FRN). Individual communication terminal devices of the communication network can be connected to the remote stations (RT1...RT3). In the event of malfunctions of the optical lines (RL1, RL2) or of the technical components (OR, OT) involved in transmission, a folded, configured ring network can be re-formed from the still intact ring network parts with the aid of switching means (LB1...LB3) and controllers (ZS, ST) arranged in the transmission system. The transmission system can be used particularly advantageously in communication networks extending over a wide area and can be adapted with regard to the requisite transmission reliability in dependence on the number of communication terminal devices to be connected. <IMAGE>
