Re: [hylafax-users] problems with Multitech Modem MT 2834ZDXb

Steve,

What is the difference between MT2834ZXD and MT2834ZXDb?

Best regards:
Milen

Milen,

I am sad to inform you that there is no active development on this product
anymore. You can tinker with the receive sensitivity, and see if it makes
any difference.

S38 controls the receive sensitivity. Its default is 43 which means -43dbm.
You could try going to 44 or 45 and see if that helps at all. As you go
lower (higher numbers), the modem will have trouble distinguishing between
noise and signal and may not drop carrier when it should.

I would recommend up dating to our MT5634ZBA-V92 if you want to use a modem
with active fax development on it.

Subject: [hylafax-users] problems with Multitech Modem MT 2834ZDXb


Hi,

I have problems with a multitech modem MT2834ZDXb  in receive-only
configuration
It fails to receive faxes with the one of the following errors:

1. T.30 T2 timeout, expected page not received
2. COMREC error
3. Missing EOL after 5 seconds (section 3.2/T.4)

Is there any known poblems with this type of modems?
Do I need to change any parameters in modem config file?

Thank you for your time and help!
Best regards:
Milen

P.S. I've attached 3 sessions transmitions bellow:
