[hylafax-users] FCS Error on multitech modem

["George H" <george.dma@xxxxxxxxx>]

Hi, I am using hylafax+ 5.2.0 and I put a multitech external serial
modem is connected to a DDI number. I'm no expert at this but from
what I am told it is an external line that is coming from an E1 module
to my modem through a gateway. I got 2 of those connected to multitech
modems. I also have 2 normal plain old external telephone lines hooked
to 2 USR modems.

I am getting a lot of errors when receiving faxes on those 2 multitech
modems. They are persisting for certain machines that connect to my
hylafax server. The USR modems are not getting the same quantity and
the USR modems were in use way before the multitechs.

I notice a trend ... all the faxes that failed have "BAD HDLC" errors
for every page that it transmits. And I also see this

Dec 17 12:19:33.59: [ 8658]: MODEM Command error
Dec 17 12:19:33.59: [ 8658]: FCS error

I've read in other emails that this maybe due to line noise and coming
from faxmachine without ECM or something like that.

Thanks.
