Problems solved by technology

[0004] The disadvantage of the more common head-end equipment used in EOC technology is that its functions are completely implemented by the main chip, so it cannot meet more complex applications such as network management, and the scalability is not strong.
There are also some head-end devices that implement network management functions by adding dedicated chips, or improve the expansion performance of head-end devices, but these head-end devices are usually more complex in structure and cost higher
This has a negative impact on the popularization and application of EOC technology

Abstract

The invention relates to the head-end equipment of the Ethernet over coax. The equipment comprises an Ethernet over coax module and an Ethernet interface unit, which are connected with each other, wherein the Ethernet over coax module comprises a radio frequency input end and a radio frequency output end. The head-end equipment of the Ethernet over coax comprises the Ethernet over coax module and the Ethernet interface unit, which are connected with each other, and the Ethernet over coax module comprises the radio frequency input end and the radio frequency output end, so that the head-end equipment of the Ethernet over coax has a simple structure, and is low in cost and high in extensibility; and a network management unit can be conveniently added to realize a network management function.

Description

technical field [0001] The invention relates to the field of network equipment, in particular to the field of network head-end equipment, in particular to a head-end equipment of coaxial cable Ethernet. Background technique [0002] my country's TV signal mode is gradually shifting from analog signal to digital signal, and the cable TV network is changing from one-way to two-way, thus realizing the transformation from single function of the network to triple play and triple play. The demand of the market and the continuous development of new TV technology require the cable TV network to realize the two-way user access of the whole network. However, the previous two-way user access technologies, such as CMTS+Cable modem and FTTB+LAN technology, can no longer meet the competition in the two-way user access market and the development of two-way integrated services in cable television networks. Therefore, the two-way access technology based on coaxial cable - EOC (Ethernet Over...
