Apparatus and method for improving traffic bandwidth in bts

The present invention relates to a redundant board unit in the base station system, a two-to-parallel converter is connected to a serializer of the first board of the other redundant board, and the other is connected to a serializer of the second board of the opposing dual board of and, of the two, and a control unit for controlling the bus switch in accordance with the state of the other party redundant boards with or of PLL (Phase locked Loop) lock (lock) to parallel converter, the outputs of the parallel converter under the control of the controller and a bus switch for outputting by selecting one, comprises encapsulated (FIFO) for outputting to the mux receives the output of the bus switch in the cell unit. This invention has the advantage to improve the bandwidth of the mux / demux input to ensure that only the cells to the multiplexer to be transmitted in one board.
