Make sure the telephone cord is connected to
the telephone line connector.
Attach a telephone directly to the wall outlet to
verify that a dial tone exists.
Disable the Dial Tone Detect configuration
option (X0, X1, and X3) and dial the telephone
number. This will force the modem to dial
without detecting a dial tone on the telephone
line. This type of dialing is known as Blind
Dialing. NOTE: Blind Dialing is not supported in
some countries outside of North America. Refer
to Table 4-3 in Chapter 4 for more information.
You may have a poor telephone line connection.
Try dialing again.
The remote modem may have encountered an
error control disconnect, where the modem is
configured to establish a call using error
correction. If the modems cannot negotiate error
control, then a disconnect occurs.
Your telephone may have Call Waiting enabled.
Refer to your local phone book for procedures to
disable this feature.
Perform a Local Analog Loopback (&T1) test to
check the modem's hardware operation.
