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.

Webinar: Effects of User Activity on Broadband CPE Throughput

Join us on Tuesday, October 6, 2015 at 10:00 and 14:00 EDT Register for the Webinar Broadband users are demanding. A sudden change in the subscriber experience means support calls or shopping for new devices. QA teams often test to ensure line-rate throughput, but how does a device perform over time? How does it perform more »

Testing IPv6 Devices in CDRouter (Video)
Tags: Business Gateway, Home Router, IPv6, Service Provider Networks

IPv6 is a complex protocol. With the transition of broadband to IPv6, home and business networking devices are hard-pressed to operate correctly. The CDRouter IPv6 add on lets you ensure that your devices can perform in an IPv6 environment. Join the QA Cafe support team as we show you: The basics of setting up and more »

TR-069 Data Model Testing in CDRouter (Video)
Tags: Home Router, Service Provider Networks, ssl, TR-069

The TR-069 add on turns CDRouter into a scriptable ACS to test your TR-069 enabled devices for protocol conformance and Interoperability. One of the most important series of tests is validating that your device’s TR-069 data model is accurate, valid, and can be manipulated using TR-069 RPCs. Join the QA Cafe support team as we more »


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

TR-069 Training Series: Overview of a TR-069 Session
Tags: Business Gateway, Home Router, Service Provider Networks, TR-069

Overview of a TR-069 Session TR-069 refers to the Technical Report published by the Broadband Forum that defines the CPE WAN Management Protocol, or CWMP. CWMP was developed to allow providers of broadband services to deploy and manage customer premises equipment in home and business networks. In the beginning, TR-069 was targeted towards the home more »

Protecting Against Vulnerabilities in SSL
Tags: Business Gateway, Core, Home Router, security, ssl

Well, it’s official, the IETF is deprecating SSL version 3.0. This means that it will no longer be standard to fall back to SSL 3.0 in protocol negotiations, and for good reason: there have been a host of vulnerabilities in Secure Socket Layer, some of which are of particular concern to home networking devices that more »

Verifying TR-069 “real world” scenarios with a native ACS
Tags: ACS, Service Provider Networks, TR-069

When it comes to testing TR-069, there are three main stages: Testing that your device handles CWMP and the underlying protocols Testing that your data model objects and parameters are valid Testing that your CPE will behave as expected in production CDRouter’s automation platform can make it very easy to do all of these, and more »

CDRouter gives detailed test results after every test run that lets you get to the root of problems faster. Besides being useful for your own analysis, CDRouter test results can be used to proof your device’s performance to your product manager or to your customers during the sales support process. Here’s a few ways you more »

Testing Wifi Scalability with Wireless Station Virtualization
Tags: Access Point, Business Gateway, Home Router, Multiport, Wifi

Nearly every home device has Wifi capability, and with the emergence of the Internet of Things, that number is likely to increase exponentially. It will be more important than ever to ensure that Wifi routers and access points can handle the load and the applications that are likely to be accessed by all of these more »

Is your device using valid TR-069 data models?
Tags: Home Router, Service Provider Networks, TR-069

The CPE WAN Management Protocol described by Broadband Forum TR-069 is a remote procedure call (RPC) based protocol. That is, it consists of two applications that interact directly with each other through a set of defined methods – in the case of TR-069, this includes device functions like Reboot, Download, etc., as well as operations more »
