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 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 or not your phone line is digital.
If your phone system requires dialing "9" to access an outside
line, be sure to add "9" 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 isn't achieving a 56K Internet connection.
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
connections currently support.
•
The telephone line between your ISP and your modem must be
capable of supporting a 56K connection and contain only one
analogue-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 digital-to-analogue signal
conversion so that your modem can receive the data. There
must be no more than one analogue-to-digital signal
conversion in the path from your ISP to your modem. If more
than one analogue-to-digital conversion occurs, your
connect speeds will default to V.34 (33.6 Kbps). There may
also be impairments on the local lines between your ISP and
