Modem Issues

How do I test to see if V.90 connectivity is possible?

1. Set a HyperTerminal terminal emulator for 8 data bits,1 stop bit, and no parity (N). 

2. Dial 1-847-262-6000 to reach the USR Support BBS - Total Control Rack for modem testing and connection analysis. 

3. Once connected, and prompted for graphics, enter N for no. 

4. Enter the following: First name= line Last name= test. 

5. Check for the following banner at the end of the test: "This connection supports 56K technology" 

6. If the banner appears, the line is likely able to connect to V.90 technology. (This test is not guaranteed accurate.)

7. If the banner does not appear, the path connected from end to end is not compatible with V.90 or 56Kbps connections. The incompatibility prevents you from achieving connection higher than V.32 (33,600bps).  
   
   Note: A customer using an X2-only modem cannot get better than a V.34 connection, even if he or she appears to connect at 56Kbps to the USR test site.   X2 is a proprietary protocol, and 56Kbps line diagnostics are not modem dependent. A V.34 modem will also incorrectly show a 56Kbps connection to the USR test site.
