Abstract

PURPOSE:To increase the using efficiency of time slot and to reduce the access time, by assigning the aquisition time slot dynamically to a slave station required to catch a transmission time slot. CONSTITUTION:The device consists of a reference synchronizing burst signal generating circuit 1, a synchronizing burst receiving circuit 2, a monitor circuit 3, an aquisition time slot request signal additional circuit 4, and a concentrated line control circuit 5. The monitor circuit 3 discriminates if a slave station synchronizing burst signal is received based on a received synchronizing detection signal (e) every station, and the result of discrimination is arranged in series in timing, so that it is same type of format as the signal (e), to obtain a discrimination signal (f). The request signal additional circuit 4 forms an aquisition time slot request signal only to a slave station in which a slave station synchronizing burst signal is not received, according to the discrimination signal (f), it is added to an incoming control signal (d) and the result is introduced on the circuit 5 as a control signal (g) relating to the time slot request to form an outgoing control signal (a).
