Telecommunications transmission test set
DCFirst Claim
1. A hand-held test set for testing a digital subscriber line (xDSL) communications network, comprising:
- at least one xDSL signal input port that connects the test set to the xDSL communications network;
an xDSL modem module that attaches removably to the test set, wherein the xDSL modem module emulates a particular type of xDSL modem, enabling the test set to test the xDSL communications network in accordance with the particular type of xDSL modem;
a keypad for entering a user selection;
a processor, coupled to the xDSL modem module when the xDSL modem module is attached, that receives the user selection, that operates with the xDSL modem module to selectively perform xDSL connectivity testing in accordance with the user selection, and that processes xDSL connectivity test data resulting from the xDSL connectivity testing; and
a liquid-crystal display that selectively displays the xDSL connectivity test data in accordance with the user selection, wherein the test set is configured to perform ATM connectivity testing.

Abstract
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.
