My company is just starting up a project in Cuba where we want to send daily
e-mail progress reports from the location to our main office in London. We
had an IT person out there last week but he was unable to get the modems to
connect properly. I have spoken to the site myself dialling one of the three
IDD lines we have had installed. The voice quality is quite good, but there
is a big time-delay echo. I have experienced similar in the past on
satellite lines that have not been running proper echo cancellation
routines.

Does anyone have a good modem set-up string that will handle this "echo".
That seems to be the root cause of the problem.

On my last trip to Cuba I was able to connect to an ISP in the UK without
difficulty. This was in Havana, though, and the lines there do not suffer
quite as bad an echo. Our new project site is in a much remoter area and I
would think that the IDD lines we have had installed are routed through a
less advanced central.

Thanks in advance for any help.

In the first instance I'd suggest you see if you can establish a good
fax connection over the same phone lines, preferably using fax 
machines rather than PCs with modems. This will give you some idea of 
how bad the situation is. I've had problems with fax connections with 
Cuba.

If you just need to send progress reports, consider using an Internet 
Provider in Cuba, if available and communication is possible; or fax, 
if it works.

It is possible to send binary data by fax at a pinch, though I don't 
know how reliable it is with really bad lines (it does have error-
correcting capability).

Best wishes,

Thanks for your suggestions. We are actually able to send and receive faxes
from our Cuba site without many problems. This is what leads me to believe
that our problem is related to modem set-up. The reason that I want e-mail
connectivity is that I want to receive progress transaction files that are
to be merged into a global database in London. We can access a national ISP
in Havana from our Havana office, but not from our remote project site, not
even via long distance connection. This may sound a bit odd, but that's the
way it is in Cuba...

Any other suggestions would be most welcome.
