We have seen this, but only when a portmaster was full though. It turned
out to be a hunt group misconfiguration on the the part of our telco.
Since that has been fixed we have not had any reports of fast busies.

Again, this is something that we have seen. It turned out to be a timing
problem between our telco's OC-12 ring and our location. The reason that
rebooting the PM3 seems to fix the problem is that it appears to be the
accumulation of errors that eventually brings down the Portmaster
(admittedly a bug or deficiency of some sort). Once the timing issues
were resolved, we stopped experiencing this problem.

This also is something that we have seen on a fairly regular basis. It
does not appear to be related to heavy usage of the box as it occurs on
boxes that get very little traffic. Resetting the box fixes the problem.
If anyone has any thoughts on this...

We have seen this as well. The idle timer for the second B channel of a
multilink connection does not work properly.
We are currently running ComOS 3.5c6.
Overall we have been *extremely* happy with the PM3's. We previously had
USR Total Control I-Modems (BRI) that were just horrendous. I wouldn't
wish those one anybody.
