A transmission system includes a plurality of remote units in communication with a station unit, wherein communication is with fixed length cells in the upward direction from the remote units to the station unit by a TDMA system, and in the downward direction from the station unit to the remote units by a TDM system. The station unit is adapted to detect whether one of the plurality of remote units is in a standby state and is responsive to a detection of one of the plurality of the remote units being in a standby state to allocate bands of communication from the remote unit in the standby state to a remote unit in a normal state.
