ABSTRACT:
A remote test site is connected to a maintenance port of a long distance carrier switch. The remote test site is capable of placing calls through the maintenance port of the long distance carrier switch, testing from the switch forward to the called party for any trouble occurring in the elected call path. A test site terminal connected via an X.25 network, permits remote access to the test site. Segments of a calling path are identified via the test site terminal to the remote test site. Calls are placed through various long distance carrier switches involved in a call path to isolate the trouble occurring in a path reported by a dissatisfied customer. Calls may be placed through selected output ports of each switch identifying to the maintenance port of the switch the output port number and the destination digits for the call.
