TOP LEVEL MAINTENANCE PROCESSOR FOR RECOVERING COMMUNICATION PATH ERROR FOR FULL ELECTRONIC SWITCH AND OPERATION METHOD OF THE SAME

摘要

PURPOSE: A top level maintenance processor for recovering a communication path error for a full electronic switch and an operation method of the same are provided for continuously providing a service by preventing an error in an alarming process, maintenance function and charge blocking function by overcoming the error in a communication line. CONSTITUTION: An ACTIVE top level maintenance processor(20) sets a switching number to "0"(S1) and outputs a loop back signal through a path(1) and judges whether the loop back of the path(1) is failed(S2). If the loop back of the path(1) is failed(YES), the ACTIVE top level maintenance processor(20) increase the switching number by 1 and switches to the path(20(S3) and outputs a loop back signal through the path(2) and judges whether the loop back of the path(2) is failed(S4).
