How to set variable speed for sending faxes over satellite IP channel

Xavier Ferrer Sep 12, 2011 03:44PM EDT

We developed an application that uses FaxMan SDK for sending a fax with a PDF attached and it works fine on fixed-line analog or digital, using constant speed (for example 9600bps or 4800 bps).

The PROBLEM is that it doesn't work if we want to use it over a satellite IP channel. We have analysed that the delay introduced by the satellite channel "kills" the fax sent, and only a 10% of faxes arrive to the recipient.

We have found other applications that work perfectly over the satellite IP channel because they send faxes in a variable speed according to the recipient information about the status channel.

We think that FaxMan should be able to do the same, that is "can send faxes with variable speed", no? Is this possible? For now, we don't find the way...

Could you help us?
Or could you report our case to a technician?
More explicitly, if we use the following easy code, how we can send the fax with variable speed according to the recipient information about the status channel??

FaxMan faxMan = new FaxMan();
DataTech.FaxManNet.Fax fax = new DataTech.FaxManNet.Fax();

fax.SenderName = "Exemple_Sender";
fax.FaxNumber = "0034932640656"
fax.FaxFiles.Add( filePDF );
faxMan.SpeedFax(9600); // how I can do it variable??
faxMan.SendFax( fax );

We would appreciate a prompt response if it’s possible.

Thank you for your collaboration.

We have answered the other emails you sent. Basically the answer is to set the maxspeed for the modem port to specify that Faxman limit the connection speed. That may help but faxing over a satelite connection can be problematic due to the excess latency due to the satellite transmission.

Thanks for your interest in our products and please let us know if you have any questions.
