ACCESS NUMBERS & LINKS:

In order to really test your modem you need to call more than just 1 (your ISP's) number. If you are not getting 56k connects, you should try your modem with other local/toll/toll-free numbers. This is a list of some toll-free numbers, the 3Com "Line Test" Number (a toll-call), and links to various ISP local access number listings Setting up an account with a Free ISP is another way you can test and isolate modem/ISP problems. (But, before you go installing all the FreeISPs out there, check this out!)

1-847-330-2780 - USR Linetest number - this is a toll call; if you log-in as "Line Test" with a v.34 modem, it will attempt to determine if your line will support 56k connections.

1-847-330-4569 - US Robotics' V.92 Test number - this is a toll call; the server is a 3Com Total Control HiPer ARC running V.92 server side code that supports PCM upstream.

The following numbers use toll circuits but are free to the caller (as long as you don't log in):

1-800-245-3828 - (Canadian weather BBS)
1-800-590-4857

LINKS PROVIDING LOCAL ACCESS #s for NATIONAL/REIGIONAL ISPs:
Note -
When trying numbers, it's helpful to try a variety of server modems, and it helps to know what they are. The table below lists the brand of server modem primarily used by the ISP - if I know. In addition to the servers listed, many local ISPs also use Lucent/Livingston Portmaster (PM3) or Cisco (AS5200/5300) equipment. The PM3 is another 'class' of modems; Cisco has two modems available - one is Rockwell-based, and one Cisco-in-house (Mica). ALL server modems have a multitude of firmware releases, which may also affect connectivity. In some cases, you may be able to determine what kind of equipment is used at an access number by dialing in with HyperTerminal: some ISPs may include a text login prompt that identifies the equipment (ie, TNT=Ascend, PM3 or Portmaster=Lucent, USR or HiPer or TotalControl=3Com).
