Re: [hylafax-users] Decrease error check will prevent T.30 T2 timeout error ?

["Andrew Rinaldi" <andrew.rinaldi@xxxxxxxxxxxx>]

Hi George,

You must decide what is important to you.  If you can accept error rates of
3 in 120 then return to Class 2.  If not, then use Class 1 and buy yourself
a better modem.... this really is the only way that you will get to low
error rates.

Please remember that in Class 2 it's that modem that's doing most of the
work and therefore it's up to the modem to get it right (i.e. the fax
application can do little to overcome some bugs).  In Class 1 the fax
application is doing most of the work and can therefore overcome many
problems... HOWEVER, it's not doing everything and must rely on the modem to
do some things correctly.... USR modems have know bugs and will give you
issues... sorry, but that's how it is.

If the Multitech's that you have chosen are based on the Agere Venus chipset
then you will get better results.  Again, you must use Class 1 to allow
HylaFAX to do the work.  If these still do not meet your requirements then
buy yourself a fax board based on the latest Agere chipset, CFAX34, from a
company that's actively developing fax firmware;

timeout error ?

I have hylafax running for a week now with that USR modem on Class 2.
I only got maybe 3 error pages during that week out of 120 faxes. Then
from a previous post Lee recomended I swithc to class 1. I did and now
for 1 day I been getting lots of T.30 T1 Time Out  and T.30 T2 Time
Out.

I am seriously thinking of switching it back to class 2 and see the
difference. We get faxes from the same numbers everyday .. aprox 20
(minimum a day) so if I see less errors using class2 than class 1.. I
can assume it's better. Plus I got a bunch of multitech modems aswell
I can mix them in and see which ones work better :P

But so far you're telling me that it is MY modem that is causing the
problmes? How do I know it's not the sender's fault and not mine ?
