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.

Here you will find our knowledge base of information related to this interesting and challenging world of CPE devices.



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

SNMP Scenario Testing

CDRouter 10.1 adds the ability to build custom “scenario” tests to exercise the behavior of a DUT’s SNMP stack and MIB. Similar to our TR-069 scenarios test cases, this allows you to set up tests that perform SNMP get requests, set requests, etc. on MIB objects specific to your DUT to see if the correct more »
