ABSTRACT:
A telephone subscriber loop testing system is disclosed which can be used for performing standard ringer continuity, noise, leakage, short circuit, and foreign voltage tests over exceptionally long subscriber loops. The sensitivity of the ringer ballistic test is enhanced by placing the reversing switch (which serves to discharge the line) at a location remote from the central office test desk and relatively near to the subscriber station.
In one embodiment, the remote ballistic test circuit is incorporated in a remote testing system for a group of subscriber lines connected to the central office through a carrier system. In this embodiment, a separate metallic test path is provided to the remote location which can be selectively connected to any one of a plurality of subscriber loops for such testing.
