Embodiment Construction

[0084] The core of the invention is to multiplex multiplexed DSL signals and then transmit them through high-bandwidth transmission lines, thereby increasing the transmission rate of the DSL signals.

[0085] System of the present invention mainly comprises:

[0086] First multiplexing processing equipment: one end thereof is connected to the central office equipment in the DSL system, and the other end is connected to the user end multiplexing processing equipment through a high-speed channel;

[0087] Second multiplexing processing equipment: one end of it is connected to the user end equipment, and the other end is connected to the central office multiplexing equipment through a high-speed channel;

[0088] The first multiplexing processing device and the second multiplexing processing device exchange the multiple DSL signals after multiplexing processing, and at the same time, the received signals are demultiplexed and sent to the respective connected entity.

[0089] Th...

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...
