CONNECTION PROBLEMS —
Dial Environments in Originate mode
Make sure the modem and PCMCIA socket are
configured for modem operation.
Make sure the telephone line connector is connected to
the modem. Make sure you are using a supported
telephone line connector.
If using AT Dialing, refer to the Table A-2, Modem —
Computer Connection.
When the modem goes off-hook, a dial tone should be
heard though the speaker. When the modem starts
dialing, the dial tone should stop as the touch-tone
signals (or dialing pulse) are sent. If the dial tone does
not break, check the setting of S11.
Refer to the Making a Call with Your Modem section in
Chapter 3 to verify that you are using the proper
command format.
Determine if you are calling out through a PBX. If so, you
need to dial a 9 and comma before the telephone
number. You can check this by trying to dial the number
from a telephone.
Verify whether Tone or Pulse dialing is needed.
Make sure both modems are using the same or
compatible types of operating modem (check the \N
settings of both modems). Note that \N2, \N3, and \N4
will cause the modem to hang up if a compatible error
correction mode is not detected for the remote modem.
Try calling in Normal mode (\N0).
