IoT Testing, particularly for consumer grade networking devices, can be difficult when the device doesn't use 802.11 or RJ45 for IP traffic. Take for example the DSL Modem: one of the most commonly deployed networking devices for home users. A typical DSL Modem will have one or more RJ45 LAN ports, but testing the WAN port proves problematic: most DSL Modems use RJ14 ports for the WAN! Enter the DSLAM. The DSLAM is the head end unit for DSL Modems. We'll talk about the underlying technologies used in communicating with the head end system (DSLAM) as well as how you can source, setup, and successfully test WAN services on a DSL modem using a DSLAM. We'll also talk about why you might want to do this and what you might find.
