I have a serious problem here.
Today (sunday) everything was fine in the morning.
This evening, no one can connect above 32K. Average is in the 20's. People
that used to connect at 42K are now limited to 28.8.
This is screwing my business. I need help. (I wish MZ was here as he would
probably know the answer to this in a heartbeat)
I have 2 different NAS units (PM3 and a USRTC) on two different CT1's
I have 2 different phone numbers leading into the separate CT1's
Both are experiencing this problem:
You dial in.
Initial negotiation
Pause for about 2 seconds
Continue connection, connection succedes, except at under 56K speed.
We have tried the following:
Replace the smart jacks
Disconnect each of the NAS's to see if either was hurting the other for some
odd reason
Rebooted both NAS's
Had the telephone company reset the switch.
Here is the log on my CISCO (my T1 thru this phone company to my upstream:

Before today, there were 699 CRC errors, which would make it appear that
something has happened to the line, but it came back up.
But, why are my NAS's doing this? The phone company claims that even tho
their switch went down for a few minutes this morning, that everything came
back as normal. They say that the padding has not been affected. They say
they see no errors on the line at all.
What in the hell could this be? Could some sort of power surge from when
the switch went from down to up came thru the CT1 and hosed my PM3 and my
USRTC??
Please - anyone more familiar with these types of issues let me know. Aside
from having a modem card go bad, and some alarms now and again when the
lines are tested, we have never had a problem this severe. There is one
other ISP in the area - the phone company in the neighboring town, and if I
can't get this fixed, this could end us here - just as we were getting close
to breaking even.
