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.
Since 2015, Excentis has been inviting the world’s leading network equipment vendors to its headquarters once a year to test their DOCSIS® 3.1 products and demonstrate interoperability with other equipment. More than offering vendors a unique chance to test in a high-tech, vendor-neutral...
Does the DOCSIS 3.1 standard deliver on its promises in real-life environments, and what considerations are needed before deployment? Discover the answers.
stabtest_1500px.jpg The case for DOCSIS 3.1 system validation Quality assurance testing provides an insurance against the damages from malfunctioning systems. In insurance it’s all about cost vs. risk, where risk is the probability of the issue times its impact. Over the years, Excentis has spotted...
Case As an operator sometimes you already need to start deploying a new CPE (typically starting with a field trial), while the device hasn't gone yet through certification or HW acceptance testing. In such case running at least a 'do-not-harm' test campaign on the first units is crucial to make...
Example case An operator was already deploying DOCSIS 3.1 equipment (both CCAP and CM) in its network, but only with OFDM enabled in the downstream. The operator wanted to enable OFDMA in the upstream, so both the CCAP and the Cable Modems had to be tested in order to validate the correct behavior...
