SHDSL / Copper Loop testing

[Mike]

Howdy,

    I'm looking for reccomendations for a copper-loop test set that can 
effectively troubleshoot SHDSL. I'm looking for more than 'yup, I got 
sync' - it would be very helpful to be able to see noise/interference as 
well as calculate loop length, check bridge taps, and any other kind of 
metallic testing that would help to identify and isolate loop troubles.

    Thank you.

Mike-
