The Remote PHY architecture helps cable operators meet the soaring demand for bandwidth and IP video while making networks less complex. Here’s how. In today’s always connected digital world, we’re using huge amounts of bandwidth compared to what people used ten years ago – and with the upsurge of Ultra...

I often get asked the question: “I’m having my HFC network upgraded for DOCSIS 3.1, what KPI’s (Key Performance Indicators) should I put in my contract?” My first reply typically is: “Who pays the bill?” I do know it’s the operator who will be paying the bill, but as always in technology,...

DOCSIS® 3.1 cable modems are expected to be backwards compatible. From the title of this post you will already expect this is not fully the case. Let’s go over some important topics to be aware of when using DOCSIS 3.1 cable modems on pre-DOCSIS 3.1 CMTSs! Downstream lower frequency band...

DOCSIS® 3.1 introduces a whole new range of possibilities for signing and co-signing images, as explained in a previous blog post. Getting the correct software version on each modem in the field can be an operational challenge. This blog post explains how the Excentis DOCSIS Signing Tool can help by co-signing...

Nothing is perfect. We all know this, and we have to live with it. However, trying to improve is a key to success. This is true for cable networks as well. A bad plant condition and interferers may degrade the communication between CM and CMTS. Luckily though there is lot...

Thanks to the power of the cloud, it’s easier than ever to break the encryption as used with DOCSIS and EuroDOCSIS. Since version 3.0 of the standard it’s also much easier for operators to counter these attacks, but despite having arrived at DOCSIS 3.1 already, not everyone already implements the...
