Common Noise (No.7) Communication error detection between signal exchanger and management system in signal network

摘要

The present invention relates to a communication abnormality detection method between a signal exchanger and a management system of a common line (No. 7) signal network, and a communication abnormality detection command and a test type are input from an operator of the management system, A second step of constructing and transmitting a response message according to the type of the test message upon receipt of the test message in the signal exchanger; And a third step of reporting an abnormal status to the operator. The test message may be used to detect an abnormal state of an application performing a communication matching function as well as a lower layer protocol, It is possible to test the abnormal state of the communication line or the communication channel connection test of the application process, By using the information and transmits a test message, the test data and compare it to be cross-echo there is an effect that it is possible to detect whether or not the top, in particular a message loss if the communication operation of the application process.
