In the following some questions are described, which – from experience – may oc-
cur during the installation.

The modem starts dialing
after the dialing command
ATD
has been entered and
reports the error “
No Dial-
tone
”.
The modem is operated at a
PBX. The PBX requires that a
code number is dialed to estab-
lish a connection
or that the flash function is
activated, before the dialing
tone is heard. The modem,
however, is awaiting a ring back
signal already before the first
digit is dialed.
After the leading digit was di-
aled without a ring back signal,
inserting a W into the dialing
string will re-activate the ring
back signal detection.
(Example
ATD0W12345
).
This problem can be solved by
blind dialing (dialing without
ring back signal) with the ATX3
command or by inserting the
character > into the dialing
string. (See Chapter 9, com-
mand
ATX,
command
ATD
)
After the
ATD
dialing com-
mand, the modem will not
start dialing right away.
The dialing lock of 3o seconds
is active.
See Chapter 5.2.8 “Dial-up De-
lay”.
