Kim,
The modem at
looks like a regular analog modem. Did I miss something?
Pansophic,
Konexx looks like it may be a good fit. The one like you refer to connects to the handset line and thus can be used with any phone but (as you mentioned) can not do automated dial out. This has a big disadvantage in that we want the remote site to respond to incoming calls and also to be able to automatically call out to deliver performance data from the site.
Konnex does have a different style (called a DPI) that connects directly to the phone line and thus (I believe) can dial out and receive calls. It is more expensive (which seems to be no longer a foator) and also must be purchased for the specific type of PBX you are connecting it to (a logistical mess).
Also regarding the availability of analog lines, it is interesting to note that one of our customers that is still waiting on getting an analog line is a major telephone company (don't want to mention it here). Regarding speed, some of the files we are transferring are quite large (>1MB even aftery they are zipped) but 33K may be sufficient.
Regarding onsite service ("while your techs are on site"

, that varies. Some sites have 24h onsite but others have regional support. Also, some are international and the remote capability has been especially helpful there as those sites often have regional support and the regions are often large. Getting files from international sites used to take days if not weeks before we had the remote connections.
I have passed the Konexx info of to another individual who is going to evaluate both styles for use both here and/or at the remote site. I'll try to remember to post a response to note that that goes.
Thanks,
Mark
P.S. In case you were curious, TCP/IP would be an ideal alternative but there is a security concern for most of our customers as that systems have access to live customer data so for name we must use a point-to-point connection. A VPN and/or firewall would probably not even address the security issues at present.
