Abstract

The invention relates to a multipoint transmission equipment system and method based on a SHDSL. The structure of the equipment system utilizes a chassis plugboard type design, and the equipment system comprises a multipoint transmission equipment mother board, a multipoint transmission equipment master control plugboard, multipoint transmission equipment line plugboard and a multipoint transmission equipment network plugboard; the multipoint transmission equipment master control plugboard, the multipoint transmission equipment line plugboard and the multipoint transmission equipment network plugboard are correspondingly inserted onto the multipoint transmission equipment mother board, wherein every line plugboard achieves functions of two-way twisted pairs and four-way telephones. The multipoint transmission equipment system and method based on the SHDSL has the advantages that a multimedia communication network with a radiation radius of tens of kilometers can be established by utilizing a central office device as the center and matching with a plurality of remote devices and repeating devices; the communication bandwidth of every twisted pair is adjustable from 128 kbps to 8 Mbps; integrated services such as broadband data (data such as videos, files and faxes) and voices can be transmitted simultaneously, and the transmission distance can reach 10 kilometers.

Description

technical field [0001] The present invention is a SHDSL-based multi-point transmission equipment system and method, which is a comprehensive digital communication equipment system integrating packet switching and circuit switching, which uses twisted pair wires as transmission carriers and uses the latest SHDSL transmission technology. Background technique [0002] SHDSL (Single-pair High-speed Digital Subscriber Line, single-pair high-speed digital subscriber line, can carry TDM (Time Division Multiplex, time division multiplexing mode), ATM (Asynchronous Transfer Mode, asynchronous transfer mode), IP (Internet Protocol, Internet Interconnection Protocol) or hybrid transmission, using TC-PAM (Trellis Coded Pulse Amplitude Modulation grid code pulse amplitude modulation) coding technology, while the line anti-interference ability is stronger, and the line transmission power consumption is lower. Existing equipment has transmission distance Short distance, narrow transmissio...
