In 2000, Excentis (at that time called tComLabs) helped develop the EuroDOCSIS™ 1.0 specification, i.e. the European version of the US DOCSIS® 1.0 specification. As a neutral and independent test lab, Excentis set up an official certification program for Cable Modem and CMTS products, on behalf of the European cable industry. As new specifications were developed, new certification programs were set up to verify standards compliance.

If you’re not familiar with the certification process this page will give you a good starting point.

CableLabs Certification Programs

The EuroDOCSIS 2.0/3.0, EuroPacketCable 1.5, Cable Gateway and L2VPN certification programs are currently offered under the CableLabs umbrella. Excentis, as an independent and neutral company, has contracted with CableLabs and executes all certification testing. Note that the Cable Gateway and L2VPN programs are also available on top of US DOCSIS.

The certification process is organized in so-called certification waves. There are four fixed certification waves per year, and each wave takes six weeks of testing. Flexible entries are also possible though, but come at a higher cost. Excentis provides its test reports to a European Certification Board, where the decision is made on pass or fail. This certification board consists of European MSO people. Details on certification wave submissions, schedule, fees, special procedures, shipping, number of samples, required documentation, etc. can be found on the CableLabs website.

Excentis Certification Programs

LTE Immunity

The LTE Immunity certification program is an Excentis program that ensures that LTE signals of a certain level do not interfere the DOCSIS operation of a Cable Modem. Further details can be found on the LTE Immunity certification page.

CM Wi-Fi (Community Wi-Fi), EuroPacketCable 2.0

Excentis also provides testing programs on CM Wi-Fi, and EuroPacketCable 2.0. At this moment these programs are not part of any official certification program yet. Excentis does offer private testing services based on the existing CEL specifications and Excentis acceptance test plans however, to both MSOs and vendors. If you're interested in these programs please contact us for more details.

Non-Disclosure Agreements and protected webpages

You will need to complete the applicable Non-Disclosure Agreements (NDAs), depending on the specifications that your product supports (EuroDOCSIS and/or EuroPacketCable NDA). After signing the NDA(s) you will receive a login for our website. With this login you get access to our participants portal (i.e. some protected webpages) and see ATPs, test certificates and keys, presentations of previous vendor meetings, etc. The NDAs are available from the participants portal.

Announce Reflector

To receive announcements (upcoming interop events, vendor meetings, etc.) please subscribe to our newsletter (and indicate at least DOCSIS as one of your interests).

Vendor Meeting

Four times in a year an NDA vendor meeting is organised. It’s a good networking opportunity to meet other vendors, CableLabs and Excentis staff, and participating MSOs. During the day a number of presentations are given, typically updates on the certification process, upcoming projects, and occasionally an MSO presentation on its current activities. Check the certification schedule to see when the next vendor meeting is scheduled. Some presentations of the previous vendor meetings can be found on the Vendor Meeting Archive.

Digital Certificates

Each EuroDOCSIS Cable Modem and EuroPacketCable E-MTA device contain unique digital certficates. If you want to submit a product for certification you must make sure that you have these digital certificates well in time (it may take a while before you have everything settled). Review all further information on how to obtain digital certificates for EuroDOCSIS and/or EuroPacketCable.


Before every certification wave Excentis organizes an Interoperability event. The goal of this one week event is to ensure that each vendor has an opportunity to conduct basic interoperability tests with other vendors’ equipment in a controlled laboratory environment similar to that used during product certification and qualification. Basic tests like ranging and registration, DHCP, data passing, stability, and voice quality testing will be the base of the Interop.
Participation in the Interop event is however not required before submission for certification. Further details on this (free of charge) event are given in the guidelines document on the Submission Info page. The registration form for this event is available on the same webpage.


During the same four week as the Interops Excentis also organizes ATP-Runs. The purpose of an ATP run is to ensure that vendors have the opportunity to have a selection of acceptance tests executed by Excentis similar to those executed during product certification and qualification. Participating in the ATP run is NOT mandatory for any product and involves a fee. Further details on this event are given in the guidelines document on the Submission Info page. The registration form for this event is available on the same webpage.

Pre-Certification testing

Another possibility to prepare your product for a certification is by making use of a pre-certification ATP testing service. Excentis then runs the ATP tests of your choice as if they were run in a certwave. This service allows more flexibility than the ATP-Run.
