Claim:
1. A method for performing physical layer auto-negotiation and link up in an Ethernet Passive Optical Network over Coaxial (EPOC) network, the method comprising: transmitting a link info broadcast message over a physical layer (PHY) link channel of the EPOC network, wherein the link info broadcast message includes a bit pattern that allows an unlinked coaxial network unit (CNU) to locate the PHY link channel by hunting for the bit pattern among a plurality of channels of a transmission spectrum of the EPOC network; transmitting a first link configuration unicast message over the PHY link channel of the EPOC network in response to receiving a reply message to the link info broadcast message; and transmitting a second link configuration unicast message over the PHY link channel of the EPOC network in response to receiving a reply message to the first link configuration unicast message, wherein the PHY link channel carries no media access control level content.
