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

[0030] The core idea of ​​the present invention is: when performing high-speed broadband access to the home with the help of twisted pair wires, the indoor coaxial network is used to complete the broadband data transmission to different access points in the user's room, and the twisted pair medium to the coaxial cable is realized in the user's room. Conversion of wire media.

[0031] figure 1 It is a flowchart of a data transmission method according to an embodiment of the present invention. Utilize twisted pair cables to provide broadband access to home services, and the broadband network in the user's room is implemented using coaxial cables, then if figure 1 As shown, the method includes the following steps:

[0032] Step 101, receiving the data transmitted by the twisted pair, performing the twisted pair decoding process after the analog-to-digital conversion process; performing the digital-to-analog conversion process after the twisted-pair decoded data is subjected to ...

Abstract

The invention discloses a data transmission method and a relay, wherein the method comprises receiving data transmitted by twisted-pair lines, transmitting through a coaxial line after doing analog to digital conversion processing, twisted-pair line decoding processing, coaxial line coding processing and digital to analog conversion processing in turn, receiving data transmitted by the coaxial line, and transmitting through a twisted-pair line after doing analog to digital conversion processing, coaxial line decoding processing, twisted-pair line coding processing and digital to analog conversion processing in turn. The technical proposal of the invention can utilize indoor coaxial line network to finish broad band data transmission to indoor different access points of users when high-speed broad bands enter households by means of twisted-pair lines.

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...
