Problems solved by technology

[0003] Those skilled in the art know that the ringing signal of the phone will appear before the voice signal arrives. The ringing signal is generally a square wave, and the spectrum resources it occupies are usually higher than 300k, which is close to the spectrum of Ethernet data. Therefore, when passing It cannot be completely separat

Example Embodiment

[0028] The technical scheme of the present invention will be described in detail below through several structural schematic diagrams of embodiments of the physical layer PHY chip disclosed in the present invention. As far as the present invention is concerned, the physical layer PHY chip corresponds to an Ethernet transmission device. Since the main difference of each preferred embodiment lies in the connection relationship between the internal components, for the convenience of description, first introduce the connection relationship between the internal components in each embodiment in conjunction with the drawings, and then introduce this in detail. Invented newly added internal logic units: error correction code encoding / decoding unit and interleaving / de-interleaving unit.

[0029] See figure 1 , Which is a schematic structural diagram of a first embodiment of a physical layer PHY chip disclosed in the present invention. The PHY chip shown in this embodiment mainly includes a...

Abstract

The invention discloses an Ethernet transmission device, which includes an error correction code encoding/decoding unit for encoding or decoding an error correction code for an Ethernet signal to be transmitted. The invention also discloses a method for transmitting Ethernet signals. Step 1: Encoding the physical layer Ethernet signal that needs to be transmitted through the transmission medium with an error correction code; Step 2: Transmitting the signal that has been encoded with the error correction code to the Peer. Through the technical scheme disclosed by the invention, the transmitted Ethernet data has strong anti-interference ability, and the effect of collinear transmission with other signals is enhanced.

Description

technical field [0001] The invention relates to the field of Ethernet communication, in particular to an Ethernet transmission device and an Ethernet signal transmission method. Background technique [0002] Based on the two-wire Ethernet technology with a transmission rate lower than Gigabit and the existing GE Ethernet technology proposed by the applicant, the Ethernet data and ordinary voice signals processed by the physical layer processing unit of the PHY chip can be transmitted in the baseband mode One or more pairs of differential lines (Cat3 or other twisted-pair lines, etc.) perform collinear transmission in two-wire mode. From the perspective of spectrum occupancy, ordinary voice signals generally occupy less than 4k spectrum resources, while Ethernet data generally occupy more than 300k spectrum resources, so the receiving end can distinguish the two through a bandpass filter. For example, at the receiving end, the signal below 64k is provided to the phone as a v...
