Switching System Test Tools
eBIRST
The eBIRST toolset consists of three different tools that support 200-pin LFH, 78-pin and 50-pin connectors and a set of adaptors that allow connection to other connector types. A supplied application program controls the eBIRST tools via a USB2 port that also provides the tool power and controls the switching system using a Test Definition File to define the test sequence. These tools work by measuring the path resistance at the switching system external connectors using four-wire measurements, quickly establishing whether the path is good, has increased resistance or has failed. Below are links to various eBIRST tool information:
