摘要：A transceiver switching apparatus and method for maintenance and repair of atroubled transceiver in a cellular base station in a CDMA mobile telecommunicationsystem. The apparatus has a switching module having a plurality of switches in

combination, capable of simultaneous control of the switches with a single control signal.The switching apparatus includes a plurality of transceivers each being capable ofgenerating an alarm signal upon occurrence of an abnormal state therein, and an alarmrelease signal upon removal of the abnormal state, each of the transceivers outputtingan intermediate transmitting frequency converted from an intermediate receivingfrequency signal on basis of a tuning frequency, at least one spare transceiver adaptedfor performing the same function as the transceivers, a receiving switching circuit havingpairs of inputs and outputs for delivering the intermediate receiving frequency selectivelyto the plurality of transceivers and/or the spare transceiver, and a transmitting switchingcircuit having pairs of inputs and outputs for receiving the intermediate transmittingfrequency selectively from the plurality of transceivers and/or the spare transceiver.
