PURPOSE:To vary the transmission burst length of a connection side adaptively by putting the burst of the connection side on a TDAM circuit in operation right behind a received initial connection burst at the moment the received initial connection burst is shifted to come to the tail of a burst train. CONSTITUTION:An initial connection burst transmitter 29 sets a burst at the tail of a free slot in the rear of a frame and a burst for initial connection is transmitted by a transmitter 23. This burst is returned by a satellite, etc., and received by a receiver 25, and the position error of the burst for initial connection obtained by a burst position measuring instrument 28 is corrected by a burst position controller 22. The moment when the received burst for initial connection is shifted to come to the tail of the burst train is estimated and the initial connection burst of this system is moved to right behind the received initial connection burst to put the burst of the system on the TDMA circuit in operation. |
