Remote PHY for Converged DOCSIS, Video and OOB (2014)

By John T. Chapman, CTO Cable Access BU & Cisco Fellow, Cisco

Remote PHY refers to the technique of moving the PHY circuit out of a device such as a CCAP and putting the PHY circuit at the end of a network. Remote PHY builds upon the work started with Modular CMTS (M-CMTS) and Modular Headend Architecture (MHA) at CableLabs. Remote PHY is an evolving set of specifications and products. This white paper will focus on the expanded definition and the updates to the transport and timing for Remote PHY and how they apply to DOCSIS, MPEG-TS video, and Out-of-Band signaling for STB.
