Navigating the world of CPE devices

If you are a vendor, provider, or user of home and business broadband CPE, you know that they are becoming increasingly complex and powerful devices. CPE operate in a world of hundreds of different protocols and topologies that are specific to each deployment.

QA Cafe University is our knowledge base of information related to this interesting and challenging world of CPE devices.

What will you find at QA Cafe University?



QA Cafe conducts regular webinars on both the basics of CPE protocols and how to test them in CDRouter.

Virtual CPE and Mobile Device Testing with CDRouter Live (Video)
Tags: Live

The CDRouter test platform is the industry standard test platform for broadband CPE, used by hundreds of vendors and service providers world-wide. It’s great for DUTs in a closed-loop lab environment, but how do you test virtual CPE, cloud dependent CPE, or mobile devices with expensive infrastructure requirements? Join the QA Cafe team as we more »

End-to-End Broadband Testing With CDRouter Live (Video)
Tags: Live

The CDRouter test platform is the industry standard test platform for broadband CPE, used by hundreds of vendors and service providers world-wide. But lab testing can only go so far – find out how CDRouter Live is changing the way quality assurance works in the broadband world by allowing end-to-end functional testing in a live more »

TR-069 Scenario Testing in CDRouter (Video)
Tags: Home Router, TR-069

If you missed our webinar on the TR-069 Scenario Testing feature in CDRouter, we’ve reproduced a video here. CDRouter’s TR-069 add-on turns CDRouter into a scriptable ACS simulator with test cases for protocol functionality. CDRouter’s TR-069 Scenario tests give you a set of tools that let you build your own rudimentary TR-069 tests to align more »


Our training guides give you an overview of how to correctly implement and test the common protocols used in today’s CPE devices.

Best Practices for Securing TR-069

Recently at DEFCON 22, a presentation was made to would-be white-hat hackers bringing to light Broadband Forum TR-069 for the first time to many unfamiliar with it. As one of the most largely deployed broadband management protocols in the world, TR-069 has quite a footprint, and a compromised system could potentially affect many broadband subscribers more »

How can end-to-end protocol testing prevent service calls?

The most well understood case for product testing is in quality assurance while a home networking product is in development, or testing its integrity between firmware revisions. But testing before, during, and after deployment can also ensure that service providers reduce costly support calls and truck rolls. We asked some of our customers, some in more »

Who is CDRouter Support (Video)
Tags: CDRouter, support

We had a chance to sit down with Brad Ritchie, head of our CDRouter Support team. He tells us about working with networking and why he enjoys working with CDRouter to improve QA Cafe customers’ broadband products.

Testing Guides

Our testing guides give you an in-depth look at how to setup and configure your test environment and configure CDRouter to test complex deployment scenarios.

The Misfortune Cookie and Security in the Home Gateway

Several months ago we talked about the revelations at DEFCON22 concerning web server security of systems meant to deploy TR-069 in a subscriber network. Most of the investigation done surrounded vulnerable ACS – that is, malicious attackers gaining access to the auto-configuration server, allowing them to control many hundreds of thousands of home devices. Recently, more »

Testing VPN pass-through on a mobile hotspot with CDRouter Live

One of the most common and yet most difficult use cases for mobile hotspots is to supply connectivity for a business user connection back to their office VPN. Unforunately, this functionality of allowing VPN to “pass through” the gateway NAT correctly is often an area that has many issues and is a prime target for more »

Tags: Core, DSL, FTTdp,, GPON, Home Router, Live, Service Provider Networks

There has been a lot of news at this year’s Broadband World Forum surrounding new broadband access topologies that are making it easier for service providers to provide fiber quality broadband services without running fiber all the way to the home. One of these topologies is referred to as “Fiber to the Drop Point (FTTP)”, more »
