Filed: 1988-12-27
Abstract: PURPOSE:To improve the redundancy of a line and to improve the reliability of a system by selecting an incoming line and an outgoing line by a selection circuit in correspondence to a command from a terminal station and switching the line to the auxiliary line. CONSTITUTION:For example, when a failure is generated in the spot F of the first incoming line 5, the command is sent from a terminal station 1 to an optical repeater 2 in order to switch the first incoming line 5 to an n-th incoming line 9 which is the auxiliary line. When the command sent through the first incoming line 5 reaches the optical repeater 2, a selection circuit (SEL) 4 is operated and the first incoming line 5 is switched to the n-th incoming line 9 like being shown by a broken line in a figure. Accordingly, an optical signal sent from the terminal station 1 to the first incoming line 5 is regenerated and repeated through a SEL 3 (broken line) by an RGU 11 and the signal is sent through the SEL 4 (broken line) to the auxiliary n-th incoming line 9. When the failure is generated in the other spot of the outgoing line, the same switching operation can be executed. Thus, the reliability of the system can be improved.
