The goal of this exercise is to find a smart way to group the SNR data over time of many channels belonging to a single cable modem dynamically to make visualization better: for example, have 24 lines appear as roughly 5-8 grouped lines that can be drilled down on.

An integral part of FBC impairments detection is channel detection. For instance, the adjacency impairment looks at neighboring channels when deciding for an impairment.

In the modern world, most Internet devices rely on APIs to function properly. But what actually is an API?

Proactively catching and fixing issues in the network instead of reacting when customers start piling up on your support centres has become the main modus operandi for service providers.

Filtering is an extremely useful method in DOCSIS cable networks. There are many use cases - for instance one could disable data channels to alleviate other impairments and thus make the connection stable or even just to match the level of service the customer is paying for.

The wave impairment is one of many impairments that can be detected on a DOCSIS FBC (full band capture) downstream spectrum. In the following, we take a cursory look at an implementation of the wave impairment detection algorithm.

Axiros recently unveiled AXESS 3.8.1, an important update to the company’s flagship and industry-leading software.
