Multiplexing transmission apparatus and method between physical layer and media access control layer

Abstract

The present invention discloses a multiplexing transmission device, which is used to provide a multiplexing transmission channel for M physical ports and N media access control ports located on a same network access node, the N and the M are positive integers, and the N is less than M; the present invention at least comprises a first multiplexing transduction unit that is connected with the physical port and used for the multiplexing / de-multiplexing of the upstream data / the downstream data output / input by the physical port, and a second multiplexing transduction unit that is connected with the media access port and used for the multiplexing / de-multiplexing of the upstream data / the downstream data output / input by the media access port, the first multiplexing transduction unit is connected with the second multiplexing transduction unit to establish the multiplexing transmission channel; and a multiplexing transmission method, which is used for the device and used to realize a multiplexing transmission between the physical port and the media access control port.

Description

technical field [0001] The present invention relates to a network system, in particular to a transmission device and method between a physical layer (PHY, PhysicalLayer) and a media access control layer (MAC, Medium Access Control) in a network system; more specifically, the present invention relates to a terminal in the same network A multiplexing transmission device and method between a physical layer and a media access control layer on a user last mile access node. Background technique [0002] With the rapid development of network technology, the problem of low-cost network access in the last mile for end users has become a bottleneck in the development of new network services. For equipment providers, since the network market is already quite mature, it is difficult for the prices of various commercial chips to drop significantly, so they have to find another way to simplify equipment and reduce equipment costs. [0003] The physical layer multiplexing chip (PHY-MUX, P...
