yes, the wires have to make connection and the door has to be closed in order for that connection to flow, the test jack is working because it is only a test jack so based on when you posted this I'm guessing it is working
I'm sure there is other info out there now that I know what to look for.
The USP(Universal Station Protector) is on the side of the NID that the customer does not have access to although you can see it. The wires run underneath the module(s) and not visible unless one is pulled. Looks like the customer can replace/pull the Universal Line Module but not the Universal Station Protector.
