[Asterisk-Users] D Channel Becoming "CORRUPTED"?

[Gatewood, Andy]

What type of Cisco access equipment are you using? I have dealt with
similar problems to this and gotten similar response from the carriers.
The root of the problem has all but once turned out to be a Cisco
configuration or code problem. Could be why the carriers more or less
tell you to talk to the hand. Check the Cisco release notes for later
versions of code and see if there is possibly a resolved (or open)
caveat that deals with this issue.

Hi,
    This is not entirely an asterisk question but I figure someone here
may know the answer to this question.
    On several occassions we will lose the ability to use one of our PRI
lines.... well for our phone system anyway.... (we also sometimes
lose PRIs on some of our access equipment, etc).   After much trouble
shooting I finally decide to reset the PRI (unplug it and plug it back
in).  This seems to fix the issue... both on the * server, as well as on
our Cisco access equipment.
    The explination the phone company has given is that perhaps the "D
channel is becoming corrupted and needed to be reset".  This sounds
like a cop-out to me.  Any thoughts?   Shouldn't I be able to expect
my PRI lines to run 100% without the need for a line reset?
