work
fine for weeks and stop. Powering the modem off and back on is the only
way
to get a page to be sent one it stops. We have replaced modems (with same
model), checked phone lines etc with no problems found. This happens
periodically. Could be 2 weeks could be 2 days. I have included a log
file
from the software that communicates with the modem. From what I can tell
it
looks like maybe the carrier was not found.

Maybe you could try a different model. Also, how clean is the electrical
power in your area? Is the system on an uninterruptible power supply? I'm
thinking a low line voltage might confuse the system. Since it's external,
it won't have all the clever power supply filtering and monitoring built
into a modern computer.
And what software are you using to mange it? Does it carefully reset the
modem with an "at&f" to reset it from scratch, or does it rely on the
pre-existing state? A lot of cheap, sloppy modem software does that. The
HylaFAX and I believe mgetty software in the Linux world do a very thorough
job of completely resetting the modem to a known state before releasing it
for other service after a call. |
