Switching apparatus and method for transceiver of cellular base station in code division multiple access mobile telecommunication system

摘要

A transceiver switching apparatus and method for maintenance and repair of a troubled transceiver in a cellular base station in a CDMA mobile telecommunication system. 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 of generating an alarm signal upon occurrence of an abnormal state therein, and an alarm release signal upon removal of the abnormal state, each of the transceivers outputting an intermediate transmitting frequency converted from an intermediate receiving frequency signal on basis of a tuning frequency, at least one spare transceiver adapted for performing the same function as the transceivers, a receiving switching circuit having pairs of inputs and outputs for delivering the intermediate receiving frequency selectively to the plurality of transceivers and/or the spare transceiver, and a transmitting switching circuit having pairs of inputs and outputs for receiving the intermediate transmitting frequency selectively from the plurality of transceivers and/or the spare transceiver.
