My main question is: can these issues be caused by a router component
beyond the PA card (i.e. engine or backplane)? As far as I understand
the 7200 architecture, L1 and L2 would be terminated on the PA, and
since I see same problems on multiple PAs, it shouldn't be the router.
In which case the common point would be the AT&T multiplexer, or
something beyond it in the telco network. Am I thinking correctly about
this?
I'm fairly certain that L2 is handled on the NPE, unless you're using
the "new" made-for-MLPPP cards (hmmm...they're made to handle MLPPP
on-PA, maybe that's a clue that L2 is off-PA on other cards).
Disclaimer: it's been a few years since I had my hands dirty with PAs.
