eurodocsis-rf.jpg Excentis uses state-of-the-art test equipment to evaluate if all samples under test are behaving compliant in several areas, and if they all are calibrated properly. A few popular test cases: Upstream Calibration This test verifies the capability of the Cable Modem under test to...

Home Gateway Testing (Page)

home_gateway.jpg Cable operators are now deploying advanced home gateways instead of simple cable modems. New advanced services, the transition to IPv6 and the ever increasing number of connected devices push such gateways to support a multitude of services and devices — fundamentally increasing...

eurodocsis-rf.jpg With over 15 years of experience as the official certification test lab for the European cable market, we tested many hundreds of products for specification compliance. Running ATP tests and troubleshooting issues is our core business, and we are experts in it. What do you want to...

OFDM(A) in DOCSIS 3.1: multiplexing, modulation and multiple access? (Blog)

DOCSIS 3.1 uses OFDM(A); this blog explains the basics of multiplexing, modulation and multiple access used with this new technology.

CM-STATUS messaging improved: why and how? (Blog)

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 and how.

The differences between US DOCSIS and EuroDOCSIS, and will DOCSIS 3.1 eliminate them? (Blog)

If you ask cable people for the differences between DOCSIS and EuroDOCSIS, the only thing they can typically think of is the difference in downstream channel width: 6 MHz for DOCSIS, 8 MHz for EuroDOCSIS. In reality there’s a lot more to it, as we will discuss in this blog post!

Ranging – Feeling the 2 bpm DOCSIS heartbeat (Blog)

While working with DOCSIS systems it is important to understand the upstream periodic ranging process. Ranging can be seen as the DOCSIS heartbeat between Cable Modem (CM) and Cable Modem Termination System (CMTS). As many people tend to struggle with the details of this process, the goal of this article is to visualize the periodic ranging process. Lets take a closer look at that ranging process – and let’s try to understand where things can go wrong during this DOCSIS heartbeat.

How to create a cable modem config file (Blog)

Cable modems get their operational parameters using config files. These config files define what the internet subscription will be, what additional services are activated and other configuration details. This blog post will get you started creating your own modem config file.

How to provision a cable modem using the ISC DHCP server (Blog)

This blog post shows how to configure the ISC DHCP server to provision cable modems. Cable modems use DHCP, the Dynamic Host Configuration Protocol, to obtain the basic connectivity settings, including a number of DOCSIS-specific DHCP options.

Take care of your cable network health (Blog)

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.
