Can you get stats out of the DSL modem as far as retries and whatnot?  I get 
that occassionally on ours as well (Sangoma S518 ADSL PCI modem) but the 
modem isn't showing anything bad (the odd collision but that's not 10s long) 
-- basically it's something deeper and I believe on the DSLAM side.

The fact that the link doesn't drop suggests that's not the problem but I 
can't be 100% sure.
