Abstract
A plesiochronous matching apparatus has a redundant system including two equipments of the same structure, that is, an on-line equipment (the reference character thereof being accompanied by 'a') and a non on-line equipment (the reference character thereof being accompanied by 'b'). When the on-line equipment (a) operates normally, the non on-line equipment (b) is made to synchronize with the on-line equipment (a), so that the non on-line equipment (b) is brought into a standby state. Immediately after that, the synchronization connection is dissolved and the non-on-line equipment operates independently of the on-line equipment. The above stated synchronization connection and the dissolution thereof are performed by a synchronization control circuit (57).
