HIGHER SPEED DIGITAL LOOP CARRIER TRANSMISSION SYSTEM

摘要

A method for reducing signal degradation in a Digital Loop Carrier System by removing signaling information normally embedded continuously in digital informa tion being conveyed over the system. The system remains in this signaling free communication mode until it detects a change in its supervisory condition requir ing that it exit from the signaling free communication mode or terminate communication allow ing the system to enter an idle mode.
