Abstract: An example method for Downstream External Physical Interface (DEPI) in Data Over Cable Service Interface Specification (DOCSIS) 3.1 network environments is provided and includes generating, at a Converged Cable Access Platform (CCAP) core, a DEPI-Packet Streaming Protocol (PSP) pseudo-wire (PW) packet including 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 the DOCSIS network environment, and transmitting the DEPI-PSP PW packet over a DEPI interface to a remote physical layer (R-PHY) entity.
