A multiplexer system (320) for a pre-cabled module (815) comprising antennas is disclosed. The multiplexer system comprises a multiplexer (380) and a device (385) for controlling the multiplexer. The multiplexer allows the establishment of an electrical path for a high frequency signal between a high frequency signal up-going link of the multiplexer system and one of a plurality of high frequency signal outputs of the multiplexer system for connecting the high frequency signal up-going link of the multiplexer system to one of the antennas or to a high frequency signal down-going link of the pre-cabled module. The device comprises a shift register having a plurality of latches (905) serially connected together, the output of each latch of a set of latches of the plurality of latches being connected to control command inputs of the multiplexer for selecting one of the plurality of high frequency signal outputs. |
