Method, system and device for realizing broadband multipoint access

Abstract

The invention provides a method, a system and a device for realizing broadband multipoint access, wherein broadband to the home of a twisted-pair switch and relay conversion equipment is realized through twisted pair cables, and the relay conversion equipment is connected with client ends through coaxial cables to realize multipoint broadband access. In the invention, the multipoint access of high-speed broadband is realized by combining the twisted pair cables used for broadband to the home and the coaxial cable used indoor for a user on the basis of the advantages of high signal transmission quality and strong multipoint jamming inhibition capability to branch networks, of the coaxial cables compared with the twisted pair cables, and the problem of high-speed twisted-pair broadband access to the home caused by the characteristic of indoor telephone lines is effectively solved.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method, system and device for realizing broadband multi-point access. Background technique [0002] In broadband access-to-the-home technologies such as very high-speed digital subscriber loop (VDSL) and long-distance Ethernet (LRE), twisted-pair telephones can be used to access the home, but high-speed broadband access through twisted-pair When entering the service, the technical obstacles encountered in the user's indoor telephone line network are very large. Often, the high-speed broadband can reach the user's door, but cannot enter the telephone line access point of each room. This is mainly caused by the following reasons: [0003] (1) The telephone line network in the user's room is a bifurcated network. The bifurcated network will cause reflection and refraction of high-speed signals, and form interference after superposition. At present, high-speed broadband can only...

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.

[0005] (3) The twisted pair sometimes cannot reach the location that the user wants to access

For example, when developing IPTV services, the location where the TV is placed in the living room of the user is different from the location where the telephone is placed, so that the user cannot receive the broadband required by the IPTV service at the location of the TV.
