PURPOSE:To shorten the delivery time by bisecting one set of line assignment plan, allowing a 1st reference station to send the one and allowing a 2nd reference station to send the other through a line assignment plan delivery channel provided on each reference burst. CONSTITUTION:Two reference stations (main reference station and sub reference station) execute the transmission of a reference burst and the delivery of line assignment plan. Both reference stations send respectively a reference burst (main reference burst and sub reference burst) at a proper position in one frame, and in the case of the delivery of a line assignment plan, a transmission frame pulse 454 and a line assignment plan delivery mode signal 455 are given, a line assignment plan memory 103 is accessed by an address signal and a readout data signal 157 is fed to a reference burst generating circuit 401 and a word relating to the line assignment plan data is set to a delivery channel provided on the reference burst. Thus, the line assignment plan data is delivered to a general station with the main reference burst and sub reference burst sent at every frame. |
