    Abstract: A coax network unit (CNU) coupled to a coax line terminal (CLT) receives a plurality of orthogonal frequency-division multiplexing (OFDM) symbols from the CLT and identifies a start-of-frame delimiter on a physical-layer (PHY) control channel in the plurality of OFDM symbols. The PHY control channel includes a plurality of contiguous subcarriers. The CNU decodes one or more forward error correction (FEC) code words that follow the start-of-frame delimiter on the PHY control channel. The one or more FEC code words provide PHY control data that include information specifying a structure of a PHY frame that includes the plurality of OFDM symbols.

    Abstract translation: 耦合到同轴线路终端(CLT)的同轴电缆网络单元(CNU)从CLT接收多个正交频分复用(OFDM)符号,并且在物理层(PHY)控制上识别起始帧定界符 多个OFDM符号中的信道。 PHY控制信道包括多个连续子载波。 CNU解码在PHY控制信道上跟随起始帧定界符的一个或多个前向纠错(FEC)码字。 一个或多个FEC码字提供PHY控制数据,其包括指定包括多个OFDM符号的PHY帧的结构的信息。
