Periodic Path Test Method between Matching Modules in a Single Subscriber Switching Subsystem in Asynchronous Transfer Mode Switching Systems

摘要

1. TECHNICAL FIELD OF THE INVENTION;Periodic path test method between matching modules in a single subscriber switching subsystem.;2. The technical problem to be solved by the invention;During the operation of the ATM switching system, the operator specifies the monitoring cycle and periodically tests the paths formed between all matching modules in the single subscriber switching subsystem and notifies the operator of the test results.;3. Summary of Solution to Invention;Bandwidth is allocated to each port connecting two matching modules to be tested, each routing module controller is informed of routing tag information to change the received test cell, and the test information is sent to the test device to start the test. After receiving the result, it records in the database and performs the test through the same method for the next test object. When the test for all matching modules is completed, the path test result is output to the operator.;4. Important uses of the invention;Path test of ATM switching system—used in the method.
