Abstract
Communication system comprising a number of subscriber stations in RF communication with a base station which has a number of sequentially repetitive time slots, where each time slot is allocated to a special subscriber station, device for changing either the frequency or the time slot configuration or both if the transmission quality deteriorates on account of modulation changes, frequency channel interference, faults in equipment or the like or due to additional subscriber stations ringing up. <IMAGE> Key to diagram: 22 - Central station 20 - Concentrator 18 - Concentrator - RPU interface 12 - Central station terminal 26 - Echo canceller 10 - Bridging trunk line 14 - Remote radio terminal 36 - VCU Channel module CCU 40 - Power amplifier 38 - Transmitter/Receiver network 42 - Subscriber station
