Are these incrementing? Looks as though you have some issues going on
here.... You might want to have the carrier test the circuit during
off-hours. Have them test *through* the CSU to the CPE side of the
DMarc.
Hope this helps!

Check for any port mis match or any rate limiting implemented?

Subject: Slow network - cause?
I have a site-site VPN network.
My main site connects to 8 remote sites over a frame relay MPLS cloud.
Connection between me and 7 sites is perfect... no problems.
One of my sites however, is experiencing very slow network connectivity.
If I ping the remote router from my workstation, I get 40% - 60% replies
with 20-30ms response times (the response times have always been
20-30ms).
If I remote desktop to a PC out there, it is incredibly slow. Also,
they connect and run all their apps through Citrix, which is also very
slow.
I checked bandwidth utilization on the router, and it is only 100-150k
out of 512k.
So it seems to me that this may be a local network device that is
slowing everything down? Could it be?
Are there any other things I should be looking at?
Thanks
