Upstream Frame Configuration For Ethernet Passive Optical Network Protocol Over Coax (EPoC) Networks

摘要

A method and system for generating upstream frames in an Ethernet Passive Optical Network protocol over Coax (EPoC) network is provided. Upstream frame configuration parameters are received by a CNU from a CLT in a link info broadcast a message. The CNU can recover the upstream frame configuration parameters from the link info broadcast message and generate at least in part upstream frame.

主权项

1. A coaxial network unit (CNU), comprising:
a radio frequency (RF) receiver configured to receive a plurality of messages from a coaxial line terminal (CLT); and an Ethernet Passive Optical Network over Coax (EPoC) physical layer (PHY) configured to recover link information from at least one of the plurality of messages and generate at least a portion of an upstream frame in accordance with the recovered link information, wherein the recovered link information includes a time span allocation for resource blocks in the upstream frame in terms of orthogonal frequency division multiple access (OFDMA) symbols, a location of a PHY discovery window in the upstream frame, or an assignment of the resource blocks in the upstream frame to linked CNUs.
