Patent ID: 7796621

Claim:
An apparatus for matching Gigabit Ethernet (GbE) signals with an Optical Transport Hierarchy (OTH), the apparatus comprising: a plurality of Gigabit Media Independent Interface (GMII) receiving units which respectively check errors in each of a plurality of GbE signals; a plurality of frame buffer units which output Ethernet frames of signals output from the GMII receiving units; an address learning and multiplexing unit which controls recording of a source address and port information included in each of the Ethernet frames output from the frame buffer units and multiplexes and outputs the Ethernet frames; a memory recording the source address and port information; a Generic Frame Procedure (GFP) sending and matching unit which matches the multiplexed Ethernet frames output from the address learning and multiplexing unit with a GFP-F frame format; and an Optical Channel Data Unit (ODU) sending and matching unit which outputs GFP-F frames output from the GFP sending and matching unit to an OTH network.
