Calls from a Hotel or
Business PBX
Normally, your LAN+Modem card waits for a dial tone before dialing. In some
cases, however, a modem cannot detect a dial tone even when voice calls can be
completed. This problem can occur when:
■
Dialing into a standard telephone network using nonstandard dial tone
conventions
■
Placing a call from a country outside of the United States, where a different dial
tone is used
■
Dialing through a business or hotel PBX or a voice-mail system that indicates
new mail with a unique dial tone (travelers often find that hotel PBXs have
unique dial tones)
■
Using telephones (such as cellular telephones) that require you to press a
button before the dial tone can be heard
If you cannot obtain a normal dial tone following the procedures provided for your
phone, you may have to reconfigure the dialing options for your communications
package. Most packages have a
Wait for Dial Tone Before Dialing
option that you
can enable or disable if your modem is having trouble detecting a dial tone. You
must disable this option to permit blind dialing.

Features
Redialing
Your modem stores each dialed number until another number is dialed. When you
enter
ATDL
, the modem redials the last number dialed.
Dialing Stored Numbers
The modem can store up to four telephone numbers. For example, suppose you
frequently call the number 555-5555. If this is the first number you want to store,
enter
AT&Z1=5555555
and
ATDS1
to dial it. If it is the fourth number you want to
store, you would type
AT&Z4=5555555
to store it and
ATDS4
to dial it.
Call Progress Detection
An optional set of result codes lets you know when:
■
The telephone number you have dialed is busy
■
The line has been picked up, but a modem is not answering the call
■
There is no dial tone on the telephone line
■
A call is coming in
These result codes, and the commands that enable or disable these result codes
are controlled by the ATXn command. See “AT Commands” on page 34 for
information on AT commands.
