AN APPRATUS FOR MULTIPLEXING, DEMULTIPLXING AND SERIES MULTIPLEXING IN THE PHYSICAL LAYER OF THE ETHERNET AND THE METHOD THEREOF

WIPO Patent Application WO/2006/114032

A1

An apparatus is for multiplexing and demultiplexing in physical layer of the Ethernet. The multiplexing and demultiplexing apparatus comprises a conversion unit for interconverting the signal of the physical layer and the signal of the MAC layer, and a multiplexing and demultiplexing unit. And a method for multiplexing, demultiplexing and multiplexing and demultiplexing the signal of the physical layer in the Ethernet comprises the step of: in the uplink, converting the low rate physical layer signal to the low rate MAC signal, setting and storing the port tag, and then multiplexing the MAC signal to the high rate MAC signal; in the downlink, demultiplexing the high rate MAC signal to the low rate MAC signal, reading the low rate MAC signal and the port tag by the low clock signal, determining the downlink port based on the port tag, and outputting the low rate MAC signal. The invention reaches the arm, by above described apparatus and method, that one or a few high rate uplink interfaces can respond to low rate downlink physical interfaces. An apparatus is for series multiplexing in the physical layer of the Ethernet and the method thereof.
