If you can see errors, put on yor camo gear. Lines, international
or otherwise, should run clean, whatever equipment is
connected so long as it's correctly configured. Like 0 errors.
The differentiators between routes and telcos are (a) how often
you get a problem, and (b) how quickly it gets fixed
(i.e. there shouldn't be differences in quiescent BER - though
route, technology and organization competence may well affect
MTBF, MTTR, Availability etc.)
