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.
Possible solution:
You may have devices between the modem
and the phone jack. There should be no line splitters, fax
machines, or other devices between the modem and the wall
jack.
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.92 and V.90 protocols allow for download speeds of up to
56K and the V.92 protocol adds upload speeds of up to 48K, 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.92 or V.90
technology at this time. In order to achieve a V.92 or V.90
connection:
•
The server you’re dialing in to must support and provide a
digital V.92 or V.90 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 digital-to-analog 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-analog signal conversion so that your
modem can receive the data. There must be no more than
one digital-to-analog signal conversion in the path from
your ISP to your modem. If more than one analog-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 your modem. These
impairments can prevent or limit V.92 or V.90 connection
speeds. All telephone calls are routed differently, so you
should try making your connection several times. One
way to test this is to dial into a long distance location.
Long distance lines are often much clearer than local
lines. It is important to note that telephone companies
are constantly upgrading their systems. Lines that do not
support 56K today may support 56K in the near future.
•
Your modem must be connecting to a V.92 or V.90 server.
A pair of 56K modems will not connect to each other at
56K speeds.
