Data lockout butt sets like the TS44 will alert you when there is data such as DSL on a POTS line. That's no guarantee though because if the DSL modem is not connected and linked up there will be nothing on the line to show it's a DSL line.

Generally I wouldn't even worry about the DSL. If the associated POTS line is working and you get dial tone that's all you have to worry about. Plug the modem in and it should link up, if not make sure the filters are installed correctly. If it still doesn't work you or the customer should call tech support.
