By Ronan McLaughlin — 5G brings together a new radio (NR), and a cloud native 5G core (5GC) enabling a service-based architecture implemented as microservices deployed in containers. The 5G architecture also delivers a true separation of control plane (CP) and user plane (UP) functionalities, which enables advanced network slicing capabilities.

By Brady S. Volpe — Proactive network maintenance (PNM) has been steadily growing in acceptance and popularity over the past several years with adoption amongst cable operators from Tier 1 such as Comcast all the way to the smallest Tier 4 operators.
Read MoreBy Ron Hranac — Linear distortions—micro-reflections, amplitude ripple/tilt, and group delay distortion—wreak havoc upon the digital signals carried in our cable networks.
Read MoreBy Alberto Campos — Cable has enjoyed advances in HFC network troubleshooting leveraging proactive network maintenance tools. PNM uses the intelligence of transport devices like the cable modem (CM) and the cable modem termination system (CMTS) for network maintenance purposes.
