Abstract :
A simple inexpensive system for checking transmission on subscriber lines has been developed. The system includes a small portable loop checker for use at the customer location and a sweep-frequency generator located at the central office. Operational field trials to determine the most effective methods of applying the system and the results obtained are discussed.
