ETHERNET ACCESS DEVICE AND METHOD THEREOF

摘要

The present invention discloses an Ethernet access device and method thereof. The device includes at least two downlink physical port units, a multiplex/demultiplex unit and an uplink physical port unit. The downlink physical port unit is adapted to convert between a low-speed physical layer signal input to/output from the access device and a low-speed physical layer load carried therein; the uplink physical port unit is adapted to convert a high-speed physical layer signal input to/output from the access device and a high-speed physical layer load carried therein; and the multiplex/demultiplex unit is adapted to multiplex and demultiplex between the low-speed physical layer load of the downlink physical port unit and the high-speed physical layer load of the uplink physical port unit.
