Asynchronous digital line subscriber broadband transmission line controlling method, involves analyzing signals between transmitter and receiver, and forming communication between transmitter and receiver based on analyzed signals

摘要

The method involves analyzing a type of signals exchanged between a transmitter (1) and a receiver (2) during a handshake. A diagnosis is established on a transmission line based on the analyzed signal type. A communication between the transmitter and receiver is cut through a large band canal to initialize another handshake between the transmitter and the receiver. An Independent claim is also included for a device of controlling transmission line illustrating a number of analog transmission canals.
