[j-nsp] Routing Statistic differs on different "sides" of ATM link? (M20 and ERX)

[F J]

Hi!
I have an ATM-link between a M20 (JunOS 8.1R1.5) and an ERX1440 (JunOSe 
7.2.0)

When I run a "monitor interface traffic" command in my M20 it looks like I 
am running 125Mbit/s on the link. But when looking in the ERX it only 
reports about 34Mbit/s. See printouts below. (I have been looking for more 
than 5 minutes and the M20 is reporting fairly the same).

Which routing-statistics should I believe in or am I missunderstanding the 
printouts somehow?

Best Regards
/// Fredrik
