Abstract

PURPOSE: To eliminate the reduction of the communication speed which is caused by a control means by ignoring the single faults occurring on a transmission line.
CONSTITUTION: An interface 3 contains a fault detection means 4, a protection period setting means 7, a ratio detection means 8, and an informing means 9. The means 4 detects the faults occurring on a transmission line 1 and sends the fault information to the means 8. The means 8 has a periodical and fixed protection period set by the means 7 and detects a period when the fault information is generated within the protection period. Then the means 9 produces no output if the fault detecting ratio is less than a fixed level and then informs a control means 5 of the fault information output when the fault decting ratio exceeds the fixed level to carry out an alarm processing.
