Abstract

The invention discloses outdoor over-current local side equipment suitable for broadband coaxial access. The outdoor over-current local side equipment comprises an RJ-45 interface, a GE-physical layer (PHY) chip, a multi-access control (MAC) chip, a PHY chip group, a plurality of radio frequency circuits and a plurality of coaxial interfaces, wherein the PHY chip group comprises a plurality of PHY chips; the RJ-45 interface is connected with the GE-PHY chip; the GE-PHY chip is connected with the MAC chip through a GMII interface; the MAC chip is respectively connected with the PHY chips in the PHY chip group through the GMII interface; the PHY chips are respectively connected with the radio frequency circuits; and the radio frequency circuits are respectively connected with the coaxial interfaces. The outdoor over-current local side equipment fully uses the conventional wired television network, so that high-speed data access of a wired television user can be conveniently and economically realized.

Description

technical field [0001] The invention relates to a field over-flow central office equipment suitable for broadband coaxial access, which belongs to the technical field of broadband multi-service access network. Background technique [0002] At present, the national cable TV industry is undergoing overall digital transformation. Digitalization of cable TV will revolutionize the business and operation mode of the whole cable TV, from one-way video service to two-way interactive data, video and audio integrated service. And only by developing new businesses, providing new services, and creating new value for users can the overall transformation be truly successful. [0003] However, new services and new operating models have put forward new requirements for the network, the most concentrated manifestation of which is the requirement for the network to be bidirectional. With the rapid development of informatization construction and the launch of various services such as high-sp...
