ABSTRACT:
In a clock recovery system for use in a ring-shaped synchronization network which comprises a master transmission device and a plurality of slave transmission devices, a clock pulse sequence is circulated in a predetermined direction from the master transmission device through the plurality of the slave transmission devices in a normal state and a fault indication signal is transmitted in the predetermined direction from one of the slave transmission devices that detects interruption of the clock pulse sequence. Responsive to the fault indication signal, the master transmission device transmits a switch indication signal in a reverse direction to the one slave transmission device so as to switch the direction of the clock pulse sequence in each slave transmission device. Responsive to the switch indication signal, the one slave transmission device transmits a switch completion signal to the master transmission device in the predetermined direction. Thus, the direction of the clock pulse sequence is automatically switched from the predetermined direction to the reversed direction.
