NETWORK TEST INSTRUMENT WITH CABLE CONNECTION AND SIGNATURE TESTING

摘要

A test instrument can be coupled to a test point and measure signals in the network. The test instrument may determine whether the test instrument is connected to a cable of the network and provide notification if the test instrument is not connected to a cable. The test instrument may also detect when it is connected to a customer premises that has been previously been tested through reflected signal signatures.
