Abstract
A service-system low-speed interface unit and a protection-system low-speed interface unit are each provided with an optical transmitting/receiving module adapted to communicate signals with a main terminal. The protection-system low-speed interface unit is provided with another optical transmitting/receiving module for communicating signals with a part-time terminal. This module is selectable by a changeover switch in the protection-system low-speed interface unit. The connected configuration in the service system and the protection system is changed to allow the main terminal to make communications using either the service system or the protection system. If the main terminal makes normal communications using the service system, the part-time terminal will be allowed to make communications using the protection system by selecting the optical transmitting/receiving module for the part-time terminal with the changeover switch in the protection-system low-speed interface unit.
