By Alberto Campos — Historically in cable, network reliability did not require much attention. Early on, when our industry focus was video delivery, we promoted the amount and diversity of content, and ensured that technology kept up with the increasing video resolutions.

By Tom Cloonan — This is no time to relax! Something big is happening! This is a new decade! It’s the 2020s!” he exclaimed. “Everything in the DOCSIS/HFC network is about to change.
By Colin Howlett — As with most technologies, DOCSIS has gone through bundling and unbundling phases over the last decade in the bundling of separate edge-QAM modulator and DOCSIS CMTS in an integrated centralized CCAP, then unbundling again with remote PHY using CCAP cores and distributed remote PHY devices (RPDs).
By Robert Ferreira and Barak Hermesh — Over the last three decades, residential broadband technology has been advancing at a fast pace, from dial-up connections to gigabit services. The technology advanced in several vectors including manageability, reliability, security and privacy.
By Asaf Matatyaou — Cloud-native virtualization supports management, control and data plane processing of high performance and mission-critical broadband services. However, it’s important to state that hardware is still required for physical layer processing, such as RF.
By Ron Hranac — The earliest cable networks were one-way — that is, signals could be transmitted only from the cable operator’s headend to the subscriber. Those one-way networks worked well for delivering primarily video services. When two-way technology was developed to support interactive services.
By Nick Segura — Delightful lessons learned from past bandwidth expansion projects allowed operators to develop best practices which support anticipating and avoiding obstacles for future projects such as extended spectrum (ES) upgrades in the not so distant future.
By Jeff Finkelstein — If you have been in the cable industry for a while, you are used to reading and hearing about new technologies on the horizon. It seems that almost daily we are inundated with the promises of new technology that will solve all our problems.
By Steven Harris — Seasoned telecommunication professionals are well aware of the improvements digital video offered over analog video in the network. Operators leveraged Moving Picture Experts Group (MPEG) digital video and RF quadrature amplitude modulation (QAM).
By H. Mark Bowers — In August 1992 in conjunction with a CableLabs conference on this subject, the Outage Reduction Task Force issued its initial findings and recommendations from the first four subcommittees. Each area of outage reduction research had a separate subcommittee.
By David Ririe — We have discussed the hurdles and challenges faced while working through the early phases of our DAA/remote PHY launch here at Cox. As we begin 2020, we are taking the opportunity to look at our overall plan and make sure that the plan still matches reality.
By Leslie Ellis — We work in an industry full of machines: From set-tops and gateways, to optical nodes and hubs, to data centers and clouds bulging with software. Which is probably why machine learning (ML) is a front-and-center topic in so many conversations, and so many industries.
By Patrick Hunter — There was an interesting network issue in the IP world that came up the other day, and it got me thinking. Like we discussed in multiple articles in the past, in any IP routing domain, there are very likely many different possible paths from one source to one destination.
By Tom Williams — Active radar is a well known method to locate objects in the air and is based on sending a probing signal out and receiving reflections to determine distances and bearings to objects such as ships, aircraft, or UFOs. In military applications there is an undesirable side effect of a radar transmitter revealing itself to an enemy.
By The Phantom — There was an event of significance to our beloved industry that occurred last summer, the 50th anniversary of the lunar landing of Apollo 11. Heck, we weren’t even haunting the cable TV industry back then.
