The ISP insists it's a CPE issue but the problem only started after their Tier 1 tech monkeyed with the DSLAM and/or the CPE (remotely) in some manner. I find it suspicious that the problem was intermittent packet loss until they tinkered, whereupon the problem became a "link no surf" issue (i.e., there's Layer 2 connectivity but zero Layer 3 traffic passing).

Depends on what you can trace in the CPE, as in, how close to the DSL interface.
Otherwise you'll need capture hardware on the DSL....
Good luck,
