PURPOSE:To secure normal system operation by preceding a time slot signal assigned to the terminal of an own station by a precedence selecting function in the case when a subscriber terminal is connected to a repeating station. CONSTITUTION:The repeating station 2 transmits a signal from a terminal station 3 in preference so as not to affect a repeating signal from the terminal station being a subordinate station even if trying to transmit to an upper station at the random time which is not inhibited at all when the connecting part of the subscriber terminal 5 of the repeating station 2 connecting a master station and the terminal station 3 fails. In the case, a repeating function being the original function of the repeating station 2 precedes at normal time by permitting the repeating station to hold a transmission precedence function. But when the subscriber terminal 5 connected to the repeating station 2 is communicating or it is detected to be trying to communicate, the signal of the time slot assigned to the terminal of the own station can immediately be made to precede by the precedence selecting function. Thus, normal communication is secured. |
