Codewords are a key feature and an important check on data transmission in DOCSIS networks. They are are often able to recreate bad bits of data corrupted by linear distortions and noise in the cable plant if the corruption is not too bad (a [...]
Every cable operator has a constant struggle with ingress. As external RF signals leak into the return path from various sources, that noise accumulates and funnels upstream to the CMTS. This cumulative effect can cause a significant impact on [...]
The days of using the "break/fix" method of troubleshooting cable plant issues are quickly fading, and cable operators have DOCSIS Proactive Network Maintenance (PNM) to thank for that. With PNM in use, operators are able to identify network [...]
If you read last week’s Part 1 in our DOCSIS series and the white paper on the Evolution of DOCSIS, you now have a better understanding of why we have specifications, what those specifications can do for the cable operator’s business and what the [...]
DOCSIS pre-equalization is a subject that every cable provider should know more about. With a simple line of code on the CMTS, you can achieve an immediate and significant improvement in your upstream signal levels.
