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!
We need Wi-Fi everywhere! People are expecting whole-home coverage and if new features like fancy antennas or beamforming technology don't cut it, strategically placing additional Wi-Fi gear in a home should increase the coverage area. However, after setting it all up, these secondary access points, repeaters and other equipment should play nice and act as one big happy network that we can use throughout the home. To help realize this, the Wi-Fi standard provides the Wi-Fi seamless roaming functionality. Let's find out the do's and don'ts in this blogpost.
In this blog post we will build a PacketCable™ 2.0 EDVA configuration file from scratch. Assembly instructions included!
This blog post shows how to use the Dashing framework to build custom web-based dashboards to monitor the progress of ByteBlower traffic tests. With real-time graphs and gauges you can keep an eye on what's happening during your tests, regardless if you're running them from one or more test scripts or ByteBlower GUI instances.
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 software images.
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 of data that can be monitored to detect quite some issues.
