It is infinitely configurable (it can be used anywhere in the world (hence, Global Modem) and it can be connected to just about anything that has copper in it - dial up, two wire, four wire, leased) and it also has a two line LCD display. This is certainly by far the fastest connecting (in terms of time to establish the connection with your ISP) modem that I have ever owned (out of a total of ten or so).

Note, that, in exchange for pefect reliability you may have a slight sacrifice in connection speed. I noticed that it was connecting a bit slower than my previous modem on this computer and discovered that the passive (telephone line operated, ie without a connection to the AC wiring for power)telephone was loading the line, resulting in the lower connection speed. Replacing the telephone with a modern one solved that problem)

Also, make sure that 1) you update the firmware and 2) you update the drivers from the Multitech website. The newer result in slightly faster connection speeds.

All in all, when you consider the hassles of unreliable modems it is simpler just to pay the premium price and get the best.

I see that currently this modem is not available here on amazon.com. It is a current production item and it is available, if not in the future from amazon.com then from many other sources)
