Remote PHY (R-PHY) is a key component in the cable industry’s adoption of a Distributed Access Architecture (DAA). This Deep Dive course examines Cisco’s deployment of R-PHY architecture and devices. Remote PHY (R-PHY) is a key component in the cable industry’s adoption of a Distributed Access Architecture (DAA). DAA and R-PHY are foundational technologies for future innovative network architectures such as Virtual CMTS (vCMTS), Cloud Native Broadband Router (cnBR), and Full-duplex DOCSIS. R-PHY enables the migration of physical layer (PHY) functions (such as RF Spectrum generation) from the Headend to the network edge - leading to more robust RF networks. The deployment of DAA/R-PHY, coupled with DOCSIS 3.1, allows cable operators to deliver ultrabroadband services with maximum downstream/upstream speeds approaching 10 Gbps/1 Gbps respectively.
You will learn the Remote PHY architecture, Remote PHY Device (RPD) installation, CLI commands used for verification and monitoring, deployment best practices, and perform key R-PHY configuration tasks during handson labs.
