摘要
The switching-in device allows a required channel (Dii1,Dii2) to be brought into use for connecting opposing communication devices (KE1,KE2), or allows a defective channel to be replaced by a redundant channel. Each communication device (KE1,KE2) has carrier signal detectors (TDE) for all duplex channels (Dii1,Dii2) used for switching to transmission mode when no reception signal is received. When a signal is received from one of the duplex channels (Dii1,Dii2) the corresponding channel (Dii1,Dii2) is selected as the actual duplex transmission path. USE - For high speed optical communications system.
