DOCSIS 4.0

Mia Colabrese2020-05-18T11:03:39-04:00February 20th, 2020|

Evolve or Die: Can DOCSIS 4.0 Compete with Fiber? The Telecommunications Act of 1996 forever changed the cable industry. It allowed cable and telecom to directly compete with each other. Data-Over-Cable Service Interface Specifications (DOCSIS) was already in development which enabled the cable industry to provide high speed data and later voice-over-Internet protocol (VoIP). It has been over a 20-year competition between telecom and cable operators, one that the cable industry has done quite well with and the telecom industry has struggled to keep up. The question we face is

Cable Haunt: Exploiting DOCSIS Modems

Mia Colabrese2021-12-15T10:13:01-05:00January 21st, 2020|

*Updated* (see patch for Cable Haunt at end of post) Cable Haunt is the fancy name given for a vulnerability recently disclosed by a group of researchers at Lyrebirds in Denmark exploiting DOCSIS modems. Cable Haunt affects cable modems using the Broadcom chipset specifically having the built-in spectrum analyzer many of us in the industry are quite fond of. Typically the forward path spectrum analyzer or Full Band Capture (FBC) analyzer in the broadcom chipset is used by the industry for proactive network maintenance (PNM) applications to

Low latency DOCSIS and gaming — a billion dollar industry we cannot ignore In the last issue of Broadband Library, I wrote an in-depth article on low latency DOCSIS (LLD). The big focus for LLD was on gaming and the rise of Esports (https://en.wikipedia.org/wiki/Esports). If you recall, Esports is a billion dollar industry with 454 million viewers in 2019 and growing very quickly. Low latency DOCSIS is required in our industry to keep millions of subscribers who want to continue to use our broadband services for the purpose of Esports
