Are the cables connecting the TWA to the TVA reg phone cords or Hand made with colered wires?
If the latter, just moving them around could cause disconnection.
Move them around and check the Green light at the same time, any reconnect the light will go solid. A lot of bad installers Jury rig these connections. If the top plug on the TVA goes directly into a plug on the TWA, try a new cord ( must be four conductor).
I don't believe trying to connect with usb would cause a problem, but crappy wiring will.
