DOCSIS Cable Modems Registration Process Even the most interesting man in the world enjoy's the DOCSIS cable modem registration process, so it is worth a second look. It is one of the most popular topics because it covers a wide range of how DOCSIS works, from physical layer to Internet protocol (IP) layer. It is therefore worthy of an encore article with more depth and an update to include DOCSIS 3.0. During the cable modem registration process it is important to understand that three (3) different levels of

DOCSIS Return | Dirty Fiber Optic Connectors

Mia Colabrese2012-09-24T03:14:16-04:00September 24th, 2012|

An often overlooked, but easy to resolve RF impairment are loose and/or dirty fiber optic connectors. This issue often manifests itself as an increased noise floor when viewed on a spectrum analyzer. The key to determining the difference between regular ingress and fiber connector noise is that the noise created by a loose or dirty fiber connector does not stop at the diplex filter roll-off frequency (typically 42 MHz in North America and 65 MHz Europe). The image below shows a perfect example of this type of impairment:

Calculating... Calculating... DOCSIS Codeword Errors - You will likely see them DOCSIS correctable codeword errors and uncorrectable codeword errors are available as a metric in most cable operator monitoring tools and Operations Support Systems (OSS). The monitoring tools and OSS generally provide data and dashboards for users to monitor overall network health and then identify a problem when it occurs. Metrics like codeword errors are extracted directly from DOCSIS CMTSs using Simple Network Management Protocol (SNMP) or Internet Protocol Detail Records (IPDR), the later being preferred due to

Advanced Troubleshooting in a DOCSIS 3.0 Plant

Mia Colabrese2020-07-02T17:55:04-04:00January 26th, 2012|

If you missed the SCTE Cable-Tec 2011, I am making available my presentation and white paper on Advanced Troubleshooting in a DOCSIS 3.0 Plant. Each speaker had only 20 minutes to cover topics that could easily last hours, so the presentations are understandably brief. Below you will find my presentation in "Slideshare" for online viewing as well as a fully downloadable PowerPoint version. The PowerPoint version also has reader notes attached at the bottom of each slide which you may find useful. In addition, the animations work a little better in the downloadable version.
