PURPOSE:To prevent the production of a bit error in a signal data attended with line switching and a line error by switching each output of an active transmission line and a standby transmission line provided on each slave station through a switching means changed over synchronously with a period when no burst wave is sent. CONSTITUTION:This system is provided with a slave station 2 provided with an active transmission line 21 and standby transmission line 22, a switching means 23 selecting any of outputs of the active transmission line 21 and the standby transmission line 22, and a switch changeover means 25 executing the changeover of the switching means 23 synchronously with a period when no burst signal is sent. Thus, the switching of the active transmission line 21 and the standby transmission line 22 in the slave station 2 is implemented for a period when no burst signal is sent. Thus, the production of a bit error in a signal data attended with line switching and a line error are prevented. |
