Re: [hylafax-users] Failed to properly detect high-speed data carrier
Kimble,
I agree with your advice.
However, in this case I see an opportunity to investigate a possibility
of improving HylaFAX. On the systems I administer I see a little less
than 1% reception errors. Half of those are due to "failed to properly
detect high-speed data carrier" errors that look rather similar to the
log that John has posted. I've investigated these problems on one
production server before, but I had to test long, long periods of
"random" and "occassional" errors to try to determine what was going
on, and in the end I found no useful result. If John has a scenario
that can reproduce the problem, then maybe I can find an answer more
easily this way.
Thanks,
Lee.

John,
Ever considered that it might be cheaper both time and money wise to
just replace the one dodgy fax machine rather than pull your hair
out. You did mention it was a remote office so I assume you have some
say in the matter.

Kimble Young

All,
I am sorry to post this problem to the list. I am getting the error
"Failed to properly detect high-speed data carrier" with a just
purchased Multitech MT5600ZDXV after also receiving the error with a
Multitech MT2834ZDXb (Class 2 only). I have read through the
archives and tried several of the suggestions therein, but continue
to experience this problem.
It seems I always get this error from the same fax machine, one in
use in one of our remote offices (Brother Model MFC 4800).
Though we receive approximately 100 faxes per day on the Multitech
modem, we get errors on every single fax from the Brother fax
machine, and occasionally see this error from other numbers (albeit
much less often.)
I wish I knew what I was looking at in the log, but I can't make
sense of it.
After some troubleshooting on my own, I have gone back to using a
vanilla config file in hopes to not muddy the waters should I get
any suggestions from the experts on this list.
I am using Hylfax version 4.2.1 under Slackware Linux 10.0.0 with
gcc version 3.3.4. Mulitech MT5600ZDXV Firmware revision
V2.300C-V90_2M_DLS (Conexant)
Modem in Class 1 (I have not tried this modem in Class 2 but it is
supported)
I believe I am using Libtiff 3.6.0, but see these files on the box
(so I am not really sure):
/usr/lib/libtiff.so.3.6.1
/usr/local/lib/libtiff.so.3.6.0
Incidentally, we send about 100 faxes per day with this same server
with no problems using WHFC on Windows 2000 clients (using a
different modem).
I really appreciate you all reading this long message and would be
thankful for any suggestions anyone might care to make.

To my inexperienced eyes, it looks like the end of the log file has
the important information on this failure. Here it is:
