Hmmm... well, in 16.5 hours it only dropped one keepalive and had one error
out of 307000 packets, which isn't too bad. there shouldn't be any at all,
but one bad packet in 300k isn't going to hurt that much.
The line certainly doesn't appear to be over-utilized by any stretch.
Hmmm... I'd still blame the telco, but that's my number one rule anyway. :-)
One thing that is worth trying is to disconnect all the relevant cables and
reconnect them a few times, especially the cable from the CSU/DSU to the
network jack. This actually resolved a problem that we had that neither I
or the telco could figure out. That T-1 is now running perfectly clean and
it was experiencing 5-10% errors before.
HTH,
