Dial-Up Networking, right-click the connection you are trying to use, and click Properties. Make
sure that the description in the modem box matches the description of the modem you are using.
If it doesn't match, select the proper modem description.
PROBLEM: My modem won't dial out or doesn't answer incoming calls.
FOR BOTH DIALING AND ANSWERING PROBLEMS:
Possible solution:
You may have a bad phone cord connection to your modem, or your phone cord may be plugged
into the wrong jack. The phone cord should be plugged into the jack labeled TELCO on the modem
and into the wall phone jack. Use the phone cord included in your modem's box if possible.
OFFICE USERS:
Possible solution:
You may have plugged your modem's phone cord into a digital line. Contact the department
responsible for your phone system if you are unsure whether your phone line is digital.
If your phone system requires dialing a prefix (generally "0" or "9") to access an outside line, be
sure to add this prefix before the number you are dialing.
VOICE MAIL USERS:
Possible solution:
If you have voice mail provided by your local phone company, your dial tone may be altered when
messages are waiting. Retrieve your voice mail to restore your normal dial tone.
PROBLEM: My modem sounds like it's trying to connect to another modem
but fails.
Possible solution:
You may have a poor connection. All calls are routed differently, so try placing the call again.
PROBLEM: My modem drops the ISP connection when I accept incoming
calls.
Possible solution:
If you are connecting to a server that does not support V.92, you will receive a message informing
you of an incoming call. You will then have the option to accept the call or to ignore it. If you
choose to accept the call, your data connection will be terminated.
PROBLEM: My modem isn't achieving a 56K Internet connection.
Possible Solution:
The V.90/V.92 protocol allows for download speeds of up to 56K, but line conditions may affect
the actual speeds during a given connection. Due to unusual telephone line configurations, some
users will not be able to take full advantage of V.90/V.92 technology at this time. In order to
achieve a 56K connection:
•
The server you're dialling in to must support and provide a digital V.90/V.92 signal. Your ISP
can provide you with a list of dial-up connections and information on what those connec-
tions currently support.
• The telephone line between your ISP and your modem must be capable of supporting a 56K
connection and contain only one analog-to-digital conversion. The 56K signal from your ISP
begins as a digital signal. Somewhere between the ISP and your modem, there will be a dig-
