A mobile telecommunications system comprising a network ( ) is described having at least one base station transceiver ( ) for communication with mobile terminals ( ) within a first geographic area (A, B, C, D). The network ( ) is adapted for communicating messages to an from the at least one base station transceiver ( ) which is connected to a first communications link ( ) of the network ( ) for receipt and transmission of user messages. The at least one base station transceiver ( ) is adapted so that when the at least one base station transceiver ( ) detects a fault in the first communications link ( ) the at least one base station transceiver ( ) continues to transmit a beacon or pilot signal; and the network ( ) is adapted to monitor activity of the mobile terminals ( ) for determination of whether the beacon or pilot signal is being transmitted from the at least one base station transceiver ( ). This allows determination of whether the fault is in the data link or in the base station transceiver.
