A test set includes at least one signal input port, a test circuitry, a processor,
a user-input device, and a display. The test circuitry couples to and receives
signals from the at least one signal input port. The test circuitry then generates
test data corresponding to the received signals. The processor couples to and receives
test data from the test circuitry and generates test results. The processor also
couples to and receives commands from the user-input device. The processor further
operatively couples to the graphical display that receives and displays the test
results from the processor. In one embodiment, the test set is capable of performing
line qualification and connectivity testing. A modem module can be used to facilitate
connectivity testing. The modem module can be a plug-in module with a common interface
to the test set. The modem module can also contain a fingerprint value that identifies
the module type and the software revision number to the test set.
