Abstract

The invention provides a coaxial network device, comprising a media access control MAC layer chip and a physical layer chip. The invention is applied in a coaxial Ethernet system. The physical layer chip comprises a transmission port applied to transmit data to the coaxial network as well as a receiving port applied to receive the data from the coaxial network. The invention also comprises an enable unit of the receiving port, which is connected with the receiving port and the transmission port, and used to cut off the connection of the receiving port and the coaxial network when the transmission port transmits data, and to recover the connection of the receiving port and the coaxial network when the transmission port is free from transmitting data. The invention also provides an isolation echo reflection method. The coaxial Ethernet switch of the invention works under the half-duplex and realizes the signal reflection by utilizing an external switch.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and equipment for isolating echo reflection. Background technique [0002] The coaxial Ethernet system uses coaxial cable as the transmission medium for broadband access in the home. A typical EOC (Ethernet of Coaxial, coaxial Ethernet) system includes CNU (Coaxial Network Unit, coaxial network terminal equipment), CLT (Coaxial Line Terminal, coaxial network head-end equipment), branch distributor and coaxial cable composition. Among them, the CLT acts as a GE (Gigabit Ethernet, Gigabit Ethernet) port, and the data stream is an Ethernet frame. The CLT synthesizes the TV signal and Ethernet data into a mixed data stream and transmits it on the existing coaxial cable; the CNU is the final In the user terminal, the uplink port is a coaxial cable, and the downlink port includes an FE (Fast Ethernet, Fast Ethernet) port and a coaxial cable port.
