Abstract
A transmission apparatus includes: a plurality of signal transmission circuits on a transmission path; a monitoring unit that detects a fault by monitoring an operating status of each of the signal transmission circuits; a controlling unit that outputs a reset instruction when the monitoring unit detects the fault; and an individual resetting unit that receives the reset instruction and resets individually each of the signal transmission circuits.

A transmission apparatus comprising:
- a plurality of signal transmission circuits on a transmission path;
- a monitoring unit that detects a fault by monitoring an operating status of each of the signal transmission circuits;
- a controlling unit that outputs a reset instruction when the monitoring unit detects the fault;
- and
- an individual resetting unit that receives the reset instruction and resets individually each of the signal transmission circuits.
A fault-recovery method for a transmission apparatus including a plurality of signal transmission circuits and a resetting unit connected to the signal transmission circuits, comprising:
- monitoring an operating status of each of the signal transmission circuits;
- detecting a fault based on a result of the monitoring;
- outputting a reset instruction to the reset unit when the fault is detected at the detecting;
- and
- resetting individually each of the signal transmission circuits by the reset circuit.
