From an engineering point of view, DOCSIS 3.1 protocol messages are pretty mind-blowing. They travel almost at the speed of light through your coaxial cable – all to support your online life. Imagine pausing time and taking a peek at the conversation between the cable modem (CM) and the cable modem termination system (CMTS). Wait, we can! Let’s have a look using the XRA-31 real-time RF analyzer that we will be launching soon.
As demonstrated during our interop event , Remote PHY Devices (RPD) are reaching maturity. Contrary to other MSO (operator) core equipment, an RPD may be installed in an untrusted part of the MSO’s network. This requires special attention from a security point of view. This blogpost explains how to update the RPD’s software in a secure way.
The Remote PHY architecture helps cable operators meet the soaring demand for bandwidth and IP video while making networks less complex. Here’s how.

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, the right answer depends on many factors. In this blog I will clarify how some of the factors play an important role.

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!
