Abstract

See full text

A method and apparatus for synchronizing nodes in a communication network. A such as an EPoC, PON, or EPoC/PON hybrid access network. The network node receives or originates a ToD value and calculates future ToD value for a second node, which the first node includes in a ToD message for sending to the second node. The ToD message preferably includes a correction based on an OFDM ranging delay value and an adjustment based on a total transmit/receive PHY path asymmetry value with respect to the two nodes. A similar future ToD message is preferably sent to each downstream node that the first node is serving.
