METHOD AND DEVICE FOR COMMUNICATION VIA DIGITAL SUBSCRIBER LINE TECHNOLOGY Russian patent published in 2011 - IPC H04B1/38 H04B7/05 

FIELD: information technology.

SUBSTANCE: method involves the following steps: receiving a communication efficiency parametre; if the communication efficiency parametre is equal to a predetermined value or exceeds the predetermined value, the first transmitter-receiver pair and the second transmitter-receiver pair use a predefined communication standard during communication, where determination of the predefined communication standard is carried out on the first transmitter-receiver pair and the second transmitter-receiver pair, respectively. A predefined bit table and a gain table are provided on the first transmitter-receiver pair and the second transmitter-receiver pair, respectively. According to the described method, in case of high broad-band noise, fast switching to the predefined bit table and gain table can be provided using a simple message or "request-response" mechanism. Use of this method avoids the need to exchange bit tables and gain tables.

EFFECT: avoiding wastage of channel capacity.
