DOCSIS 3.1 has enabled cable operators to use the incredible capacity of today's HFC plant to nearly its full potential, including delivery of ubiquitous Gigabit services. However, with great power comes great responsibility (and complexity), and getting the most out of DOCSIS 3.1 requires careful optimization. DOCSIS 3.1 also enables new and powerful approaches for interference detection, which provides novel ways to identify and isolate plant issues. In this session, Cisco’s Ron Hranac will represent CableLabs’ InGeNeOs PNM Working Group and will deliver a deep dive on how to characterize network issues like amplifier ripple and LTE-sourced interference using OFDM’s RxMER per subcarrier data. He will demonstrate how data collected from cable modems can be used to identify and locate specific cable network impairments, resulting in an improved subscriber service performance and experience Additionally, Shaw will explain its approach to balance capacity and reliability to bring high-quality customer experience and services by leveraging and properly configuring DOCSIS 3.1 features, including modulation profiles, bonding groups, CM load balancing (DCC, DBC) and dynamic upstream configuration changes.
