Description
Technical field
The present invention relates to network and connect the auxiliary device technical field, particularly relate to a kind of power line and telephone wire network bridge device.
Background technology
As everyone knows, phone bridge (Phoneline Communication), its basic principle refers to utilize the multimedia service signals such as 2 core twisted-pair feeder high speed transmission datas, voice, image; Its with need not wiring, wide coverage, easy to connect, transmission quality is high, speed is fast, bandwidth is stable, the distinguishing features such as long transmission distance, be widely used in the fields such as residential quarter, hotel, Office Area, monitoring security protection, be particularly useful for the broadband transformation of built building.
Existing operator light changes in the former fiber entering household of project, and the end of registering one's residence is the optical fiber cat; 1. build well in original building construction, fibre circuit does not enter household internal,, if accomplish fiber entering household, must through wallsly hole, and rewiring, destroy finishing; 2. in the network management platform of operator, the optical fiber cat of each end of registering one's residence has oneself S/N, code, and the domestic consumer is if open fiber broadband, and operator provides the optical fiber cat, by the in-company network management platform of operator, registers open-minded.And the S/N code of light cat is that the account and the password that dial up on the telephone with subscriber household bind together, and that is to say, the light cat is changed a family, is out of use; 3. the light cat of company of operator can provide a plurality of Ethernet interfaces, a plurality of call voice mouths, and corresponding each family of each network interface and phone port, cannot arbitrarily change between each mouthful.
The telephone wire bridge is to utilize existing 2 core telephone line transmission network signals, and transmission range can reach 1KM farthest, and maximum transmission bandwidth can reach up-downgoing 80Mbps.Can realize that network signal and voice signal transmit simultaneously; The fiber entering household mode of operator is from optical splitter, trunk optical fiber to be led the Stall corridor mouth of each unit, then by fused fiber splice by each household internal that is linked into through walls.If we encounter following problem: 1, hardware aspect to carry out the network rebuilding with original local side phone bridge: the interface that apartment corridor advances in company of operator is optical fiber port, and the interface of local side telephone wire bridge is Ethernet interface, and equipment can not access; What the fiber entering household posterior end was accessed is the optical fiber cat, and terminal telephone wire bridge is also Ethernet interface, and the light cat of terminal also has no idea to access; 2, software aspect: light changes the thing fiber-optic signal that transmits in project, and the network signal that is based on ICP/IP protocol of telephone wire bridge transmission can't use original local side telephone wire bridge transmission.Light signal must be changed into ethernet signal by the light cat; , if utilize original telephone wire bridge, just can not coordinate the network management platform of company of operator.
