APPARATUS FOR DUPLICATED RATE ADAPTATION AND TDM SWITCH OF MOBILE SWITCHING CENTER IN MOBILE COMMUNICATION SYSTEM

摘要

The present invention is to provide a redundant transmission rate conversion and TDM switching device of the exchange in a mobile communication system that, from the top to the upper control section which outputs a switching control signal THW bus control the operation of the exchanger; And a vocoder for performing vocoding of the input signal; The bus is connected to the vocoder and THW, which is connected by a time switch with SHW and bus transmission speed conversion and TDM switching unit for performing transmission speed conversion and the TDM switching function; By configuring the transfer rate conversion is connected to the switching unit and TDM bus with SHW, including a time switch that performs a switching time, in a single device having a transfer rate conversion function and a switching function with between blocks having a different transmission rate , it is possible to perform the switching operation at the same time as carrying out the transfer rate conversion.
