APPARATUS FOR ETHERNET INTERFACING

摘要

An ethernet interface device for efficiently using a communications resource is provided to interface the ethernet physical layer equipment installed at preexistence and the ethernet network equipment for being newly temporarily constructed. A network processor(130) routes or forwards single communications channel signal having a restore ethernet frame. A medium access processor(120) divides the ethernet frame into a plurality of segmented frames. Each of the divided segmented frames is allocated in one of a plurality of communications channels. The medium access processing unit delivers the single communications channel signal to the network processing unit. A physical layer processor(110) performs photoelectric conversion/line decoding of the signal received from the network processing unit and the line coding/electrical optical conversion about a plurality of communications channel signals.
