The invention relates to a mobile telecommunication system having an auxiliary routing arrangement comprising auxiliary radio channel units and monitoring circuit. The auxiliary radio channel units are arranged in the base station of the system and the monitoring circuit are arranged in the mobile telephone switch of the system. The monitoring circuit monitor the setting-up of each call in the mobile telephone switch and, when faults occur, the monitoring circuit are adapted switch off the transmitter function of an affected radio channel unit and to replace the affected radio channel unit with an auxiliary radio channel unit which is allocated a frequency essentially corresponding to the frequency of the affected radio channel unit. The automatic replacement of an affected radio channel unit with an auxiliary radio channel unit ensures that the traffic handling capacity of the system is essentially unchanged.
