Go to Start > Program > Accessories > Hyperterminal. (You can install Hyperterminal through Add/Remove Programs if you do not have it).
Click on the Hyperterm program.
Name the connection "Test" and click OK.
Enter the phone number for your ISP connection.
Ensure that it is set to be using your Lucent modem, and click OK.
Click Dial.
After the handshaking is done, you should see on the screen the word: "Login", though this does vary from ISP to ISP.
Wait a little while, say 15-60 seconds so you are connected for a bit.
Disconnect by using the pulldown menu under Call, then select Disconnect.
After you are disconnected, type ati11, press ENTER, and the following should appear with the 0's filled in(note:
press ENTER again to view the second line of information):

Basic Analysis of Ati11:
Here you want to concentrate on the Estimated Noise Level. Unfortunately LT's do not show SNR, but the Estimated Noise
Level (though varying on certain factors) can be a decent indication of noise. The value should be between 100 and 140 in most
circumstances. If it is not you may have a serious noise issue. UPDATE: I am still researching the Estimated Noise Level. It
can vary a great deal and may not be a good indication until I find the proper equation to use with it to create a true range that
it should be in. The Receive Signal Power Level is also an important value. If this value is less than 9 or higher than 25 you
may have poor line signal strength.
