Are there any 56K test lines I can call?

All of these test lines have files you can download to test your modem's performance.

DISCLAIMER - When using any of these test lines, remember that they are long distance calls. Long distance calls may be routed through telephone circuits which are significantly better or significantly worse than the local circuits used to connect to your ISP. Success on a test line does not guarantee success with your local telephone lines. In other words, your mileage may vary, differen strokes for different folks, and no two snowflakes are exactly alike.

MY ADVICE - If you've purchased a 56K modem and just want to take it for a spin, these test lines are fine, just don't count on them to tell you if your phone line supports 56K. The best test is to borrow a known good 56K modem from a friend and call a local ISP that supports 56K. (Make sure the ISP uses same kind of 56K that your modem supports: x2, K56flex, or V.90).

The USR line has diagnostic abilities to see if your line is capable of 56K connections, but the results are not guaranteed. If you do decide to use the 3Com test line, 3Com recommends making multiple calls to receive an accurate line diagnosis. When tested with multiple calls, they estimate the results to be 95% accurate. The good thing about the 3Com test line is that it can be used with a 28.8 or 33.6 modem.

3Com/U.S. Robotics test line: 1-847-330-2780
   When you connect to USR, log in as LINE TEST, and within a few seconds after that, a report will come back to you indicating
   whether or not your line supports 56K connectivity. The modems are in Illinois, so it involves a 1-2 minute tol call for most people.
