Patent ID: 8761209

Claim:
In an Ethernet physical layer (PHY) module, a method for transceiving between a 10GBASE-R client interface and a 100G attachment interface, the method comprising: on each of ten client interface logical lanes, accepting a 10GBASE-R signal; demultiplexing each 10GBASE-R logical lane into two 5 gigabit per second (Gbps) pseudo 100GBASE-R logical lanes, creating a total of twenty pseudo 100GBASE-R logical lanes; arranging the twenty pseudo 100GBASE-R logical lanes into n groups of 20/n pseudo 100GBASE-R logical lanes; arranging the pseudo 100GBASE-R logical lanes from each group into a 100G attachment logical lane; and, on each of n physical lanes, transmitting a 100G attachment logical lane at an attachment interface.
