[Asterisk-Users] Problem with T1 PRI line resetting/droppingcalls.

[Timothy R. McKee]

If you are getting a red alarm you have serious line or hardware issues.
You need to get a stand-alone analyzer on the T1/PRI to record.

I don't think the question you answered is the same as the one I asked.  The
problem with mine is the dropping of all the lines/calls.   It resets all
the lines.

I get those mystery notices on occasion also, but they don't drop all the
lines until I see the "Detected Alarm" messages for each line.

I just signed up for this list, so I might have missed your post.  Did the
person you were answering see the same problem that I do:  Dropping of all
the lines?

Thanks

The new Zaptel has the "zttest" program, which will tell you if interrupts
are being locked for too long.  This can cause the Error 500 messages you
are seeing.  Causes of interrupts being locked for too long can be:
graphics, frame buffer, IDE DMA.  There might be other things that cause
this error, I don't know.
