The CM-STATUS feature is of significant value in DOCSIS 3.x networks. However, originally it was designed in a way it was not 100% reliable. A specification addition in March 2014 changed this messaging facility and it was further fine-tuned in August 2014. This blog post provides an overview on why...

With climate changes and possible blackouts in Belgium, saving energy is becoming ever more important. So how can the Cable world contribute? The future standard, DOCSIS 3.1, promises advanced energy saving features using DOCSIS Light Sleep (DLS) mode. No need to wait though, the current specification (DOCSIS 3.0) already provides a mechanism to reduce cable modem power...

Like the mobile 4G standard LTE or the terrestrial digital video broadcasting standard DVB-T, the new cable modem standard DOCSIS 3.1 now uses Orthogonal Frequency Division techniques for signal transport. The channel consists of orthogonal subcarriers that will carry the information over the link. More on orthogonal subcarriers in our course...
