Subscriber Switching Subsystem of ATM Switching System and Connection Path Test Method between Interface Modules

摘要

The present invention relates to a device and a connection path test method for testing a port connection state and a performance state between two IMs in a single ALS. And means for matching subscribers and relay lines, and test means connected to the control means and the switching means to perform a connection path test in the subscriber switching subsystem. And receiving a path test preparation for the start interface module, and performing a path test preparation for the path test end interface module if the path test preparation of the step is completed. Outputting failure to the operator and then terminating; Extracting the routing header information if the path test preparation is completed, outputting to the operator that the path test is not performed after disabling the path test preparation for the start interface module if it is not completed, and ending the path to the test apparatus Sending a request signal for the test, being notified of the test result, releasing preparation for the path test, and outputting the path test result to the operator.
