A METHOD AND DEVICE FOR PERFORMING COMMUNICATION IN DIGITAL SUBSCRIBER LINE TECHNOLOGY

摘要

A method and device for performing communication in digital subscriber line technology. When a communication performance parameter reaches or exceeds a predetermined value, a first transceiver transmits a switch request message to a second transceiver, so that the second transceiver switches to a bit table; the first transceiver perform a synchronous switch of the bit table through a synchronous signal from the second transceiver. The bit table on the second transceiver is calculated by the first transceiver based on an experiential bit table calculating parameter that is a bit number reduced from a bit number calculated according to an actual noise; and the experiential bit table calculating parameter is received by the first transceiver from the second transceiver. There is no need of interchanging the bit table and the gain table when using this method.
