Abstract

A transmission system of DSL signal comprises the first and the second multiplex-processing devices. It is featured as interacting multiple DSL signal being multiple-processed between the first and the second multiplex-processing devices and simultaneously sending received signal separately to unit connected to each of the first and the second multiplex-processing device after received signal is demultiplex-processed for speeding up access network maximally.

Description

technical field

[0001] The invention relates to the technical field of network communication, in particular to a method for transmitting DSL signals using a high-bandwidth channel multiplexing technology. Background technique

[0002] xDSL (Digital Subscriber Loop) is a high-speed data transmission technology transmitted over telephone twisted-pair wires (ie, Unshielded Twist Pair, Unshielded Twist Pair, UTP). In addition to DSL with baseband transmission such as IDSL (ISDN Digital Subscriber Line) and SHDSL (Single Pair High Bit Rate Digital Subscriber Line), xDSL with passband transmission uses frequency division multiplexing technology to make xDSL and POTS (traditional telephone service) coexist in the same For twisted pair lines, xDSL occupies the high frequency band, and POTS occupies the baseband part below 4KHz. The xDSL of the passband transmission is realized by DMT (Discrete Multi-Tone Modulation) technology.

[0003] The reference model of the XDSL system is sh...
