AI Technical Summary

Problems solved by technology

The signal attenuation of the flat cable is obviously greater than that of the twisted pair, and the signal attenuation of the flat cable of more than ten meters indoors is relatively large.
[0006] (3) The twisted pair sometimes cannot reach the location that the user wants to access
[0015] To sum up, when VDSL or LRE provides high-speed broadband access services with the help of twisted pair lines, due to the characteristics of the user's indoor telephone line network, they encounter great obstacles

Embodiment Construction

[0031] The core idea of ​​the present invention is: the network side cable of broadband access is realized by twisted pair, the broadband network cable of user side is realized by coaxial cable, and the conversion from twisted pair medium to coaxial medium is realized, and in Media Access Control (MAC, Media Access Control) layer, the twisted pair adopts the full-duplex data transmission mode, and the coaxial line adopts the half-duplex data transmission mode, and the full-duplex data communication between the twisted pair and the coaxial line is realized. Conversion between half-duplex data.

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical key points in the present invention are introduced respectively below.

[0033] (1) The cable on the network side of broadband access is a twisted pair, and the twisted pair adopts full-duplex communication mode

[0034] The advantages of using twisted-pair cables on t...

Abstract

The invention discloses a data transmitting method, which comprises the following steps of: a network side cable of broadband access is realized by a twisted pair, a broadband network cable of a user side is realized by a coaxial cable, the twisted pair adopts a full-duplex data transmission mode, the coaxial cable adopts a half-duplex data transmission mode, and the conversion between full-duplex data and the full-duplex data is realized between the twisted pair and the coaxial cable. The invention further discloses a relay. The technical scheme can realize the half-duplex broadband access of the user side.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a data transmission method and a relay device. Background technique [0002] Broadband access to the home technology includes very high-speed digital subscriber loop (VDSL, Very-high-bit-rate Digital Subscriber loop) technology and long-distance Ethernet (LRE, Long Range Ethernet) technology. VDSL and LRE technologies can use twisted-pair telephone access to the home. [0003] However, when VDSL or LRE provides high-speed broadband access services with the help of twisted pair lines, the technical obstacles encountered in the user's indoor telephone line network are very large. Often, high-speed broadband (100Mbps) can reach the user's door, but cannot enter each room. telephone line access point. This is due to the following characteristics of the telephone line network in the user's room: [0004] (1) The telephone line network in the user's room is a bifurcated n...
