The station was designed for the integrated wideband network planned by the West German Post Office for the nineties. The narrow PCM-30 band and the 280 Mbit/s reverse direction are separated by optical wavelength multiplexing. The services are provided in a time multiplex frame of 16 channels of 70 Mbit/s each. The block diagram of the station, channel selection by sampling and by series-parallel conversion are explained. The audio part and the narrowband access for the services already in use are described.debroadband networksoptical fibresoptical linkssubscriber loopstelevision receptiontelevision stationsmonomode optical linewideband subscriber stationhigh-rate optical linessubscriber stationtv channelshigh-definition channel1.12 GHzintegrated wideband networkwest german post officenarrow pcm-30 band280 mbit/sreverse directionoptical wavelength multiplexingtime multiplex framesamplingseries-parallel conversionaudio partnarrowband access621journal article
