Example Embodiment

[0035] A specific implementation of the present invention includes several parts. The core part related to the invention is the DSLAM equipment at the central office, the CPE equipment at the user end, and the peripheral part includes a home gateway located in the residential user room, various user terminals, and the central office. PSTN switches, IP routers, etc., in figure 1 A representative network application structure is shown in.

[0036] figure 1 In, the entire topology can be divided into several parts: access network, IP switching network, PSTN switching network, home network. The access network includes the conventional DSL modem 121 at the user end, the integrated access equipment (CPE) 130 at the user end, the twisted pair cable 110, and the central office digital subscriber line access multiplexing equipment (DSLAM) 101; Large arbitrariness, such as figure 1 140, typically centered on the multifunctional home gateway 141, there may be multiple computer terminals ...

Abstract

The invention relates to a DSL bond method of multi users, wherein the twisted-pair line of nearby users is bonded into one multi-input multi-output (MIMO) logic channel; the digit user line bonded at the client terminal device (GPE) and the local terminal is accessed into the physical layer and data chain layer of multiplex device (DSLAM); the invention uses one spatial code method to integrate multi user data flows into one code bit flow to be distributed into several independent physical channels to be sent; at the same time, for reducing the interference on the same-cable line, based on multi-channel test and the estimate result of sending data flow, processing the data flow smooth access with dynamic sub carrier wave restrain, bit load adjustment and code increment control.

Description

technical field [0001] The invention belongs to the field of data communication, in particular to a digital subscriber line (DSL) access method for binding multiple pairs of twisted pairs of multiple users. Background technique [0002] From end users to the Internet, there are many standards for current access methods, such as narrowband modem (Modem), digital subscriber line (xDSL), cable modem (Cable Modem), fiber-to-the-building + local area network (FTTB+LAN) , FTTH (fiber-to-the-home), etc. These access methods have been used in homes and some small offices to varying degrees to provide data or other proliferation services, and the data rate varies from tens of Kbps to several Mbps or even tens of Mbps varies. [0003] The narrowband modem is the earliest and simplest access method for home users. It uses the existing telephone line to transmit data. It can meet the most basic applications, and there are very few users at present. [0004] DSL technology is a kind o...
