PROBLEM TO BE SOLVED: To provide a transmission line relay board recovery device which can prevent corresponding trouble to unnecessary system operation and expansion of power outage range.SOLUTION: A transmission line relay board recovery device includes error code monitoring means 11 for monitoring whether or not an error code is stored anew in each memory 2-2from each CPU1-1, and reading an error code from each memory 2-2when an error code is stored anew, error code determination means 12, 13 for determining whether an error code read by the error code monitoring means 11 is a predetermined original error code or a meaningless error code other than original error code, and restart means 14, 15 for turning a power switch 5 off only once when a determination is made that an error code is a meaningless error code by the error code determination means 12, 13, and then turning the power switch 5 on to restart the transmission line relay board. |
