Chuck,
LQM(Link Quality Moniyoring) is what you are talking about I think.
Thanks!
Yuki

Flakey circuits sometimes don't show up as a problem until you try to put a
heavy load on it. Then you notice it more. Try some file transfers in both
directions, maxing out the circuit. If it still looks clean on the
interfaces, I wouldn't worry about it. There's a PPP command (can't think
of the name) that will down the interface if errors are too great. Might
not be a bad idea, because then you'll see interface up/down messages in the
logs.

Chuck,
No, there no errors showing up on the serial.
That is why I was wondering if its causing any communication disturbance.
Someone told me that as long as it is not showing up on the router,
it is not affecting the communication. I think it does affect the
communication
somehow.
Clocking is configured correctly(I have other circuits configed exactly the
same)
by the way.

Yes, it probably is causing some other problems for the higher layers.
First make sure your clocking is set correctly. If the carrier is providing
clocking, then your DSUs should both obtain it from the line. If they're
not providing clocking, then one of your DSUs should provide clock. If your
clocking is OK, then you may have noise on the line or something else. Are
there any errors showing up on the serial interfaces?

Group,
This is an off-topic question.
I have a simple PPP connection. On one DSU, I have Errored Second
counting up.
It is aboout 10~20 ES every 15 mins. I was wondering if this causes any
communication
disturbances on the higher layer.On the other DSU, I do not see any ES.
Thanks!
Yuki
