Some Comtrend modems can do a port mirror of the WAN (DSL) side.

problem? 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, Jaap
I can get up to the DSL modem itself. In hindsight, I'm thinking this isn't going to be of much use and the only way to debug this is with capture hardware on the DSL side as you suggested.
