3.4 Making a Call
When you have successfully followed the start-up procedure in Section 3.1,
the modem should be ready for operation. If you are using the PSTN, you
will need to make a call.
3.4.1 Dialling
To dial a number from your command terminal, type
ATD
followed directly
by the number you want to dial, then press
RETURN
. For example, to dial
0123 456789 type ATD0123456789 <CR> .
If you are connected to a PBX line, the number for an outside line (for
example 9), must be inserted immediately before the number you want to
dial. On some older PBXs you may need to insert a comma after the
number for an outside line, to cause a delay before the modem continues
dialling, for example
ATD9,0123456789 <CR> .
3.4.2 Call Progress
During the progress of the connection, various messages may appear on the
screen:
RINGING while the ringing tone can be detected from the remote
end.
CONNECT
after successful connection to the number you are
calling.
If there are problems, the following messages may appear:
DIALTONE if the modem detects dial tone when it is not expected.
The modem then disconnects the call.
NO DIALTONE
if dial tone is not detected when the modem goes on
line.
NO ANSWER if the number you are calling does not answer. The
modem disconnects automatically.
VOICE
if the call is answered but answer tone is not detected.
This usually means that the call has been answered by
a person rather than a modem.
NO CARRIER if the modem you are calling 'answers' but cannot
communicate with your modem.
