Claim:
1. A method comprising: generating, at a Converged Cable Access Platform (CCAP) Core, a Downstream External Physical Interface (DEPI)-Packet Streaming Protocol (PSP) pseudo-wire (PW) packet comprising a PSP sub-layer header having a same length for a Quadrature Amplitude Modulation (QAM) channel and an Orthogonal Frequency-Division Multiplexing (OFDM) channel in a Data Over Cable Service Interface Specification (DOCSIS) network environment, wherein the PSP sub-layer header includes a profile identifier (ID) corresponding to a particular profile for the OFDM channel; and transmitting the DEPI-PSP PW packet over a DEPI interface to a remote physical layer (R-PHY) entity.
