Free-throw line Modem and bus type multi-medium multi-point networking broadband network thereof

Abstract

The invention discloses a free line Modem which is characterized by comprising one or any combination of a telephone line, a coaxial line, a network line, a twisted-pair and a balanced line. The free line Modem comprises a controlling and processing module (A), a power supply module (H), a standard Ethernet physical interface (B), an Ethernet protocol processing module (C), an any line protocol processing module (D), a line modulation / demodulation module (E), an any line simulation front end module (F) and an any line physical interface (G). A bus type multi-medium multi-point networking broadband network constructed by using the any line Modems comprises at least two any line Modems and multiple kinds of line passive branch networks (f) and is connected with an external device through the network line, wherein the external device is a user terminal device (g) or broadband access terminal (c), and topological structures of the line passive branch networks (f) are chain-shaped, star-shaped, tree-shaped topological structures or mixed topological structures.

Description

1. Technical field: [0001] The present invention relates to a kind of modem that can utilize arbitrary communication lines to form a network, hereinafter referred to as "Any Wire Modem" (Any Wire Modem), and its communication lines include telephone lines, coaxial cables, network cables (such as five types of lines), twisted pair Any metal communication lines such as wires and balanced wires. [0002] The present invention also relates to a bus-type multi-media multi-point networking broadband network constructed by such an arbitrary-line Modem, hereinafter referred to as "any-line broadband network". [0003] The product equipment and network system of the present invention are mainly used in the field of home network / SOHO network, and can also be used in the field of small local area network / office network. 2. Background technology: [0004] At present, there are several networking technical solutions in the field of home network / SOHO network and small LAN / office network....

AI Technical Summary

Problems solved by technology

However, this solution requires: the access device must be equipped with enough ports; the user terminal in each room needs to be equipped with a network cable; all houses need to be pre-arranged and buried with multiple Category 5 lines during decoration.

[0008] Its disadvantages are: the ports configured by access terminal devices are limited, which may not be able to meet the needs, and it is not convenient to expand; even if port expansion devices are added, the cost will increase accordingly, and the problem of network connection between rooms cannot be solved.

[0012] Its disadvantages are: on the one hand, all kinds of broadband access terminal equipment (such as set-top boxes, PCs, VoIP phones, etc.)

[0016] Its disadvantage is that it may be affected by the interference of neighbor networks or some electrical equipment, sometimes resulting in unstable real-time high-bandwidth signals

In addition, it may also be affected by the material, wiring length, topology and electrical interference of the household power cord. The bandwidth consistency of different households is different. It may be that the bandwidth of individual sockets in individual houses of some households is not high enough.

[0017] None of the above existing broadband home network solutions can meet the requirements of all rooms, multiple services, and multi-point global broadband coverage of the new generation home network, as well as the economic applicability of easy use, easy expansion, simple operation, and low cost, and Environmental requirements for stability, safety, intelligence, environmental protection, and green energy saving
