Yes, but would this result in more or less noise than an open end acting like an antenna? And would the ground loop noise be in the DSL spectrum?

Have you considered grounding one end (or both) of the free pairs? Perhaps this would reduce the amount of noise they pick up.
Grounding both ends will probably result in "hilarity ensues". And I suspect that Anurag can't ground the free pairs, because the copper belongs to the provider. *** SCLHS Confidentiality Notice *** The information contained in this message may be privileged and confidential and protected from disclosure.
