In the following some questions are described, which – from experience – may oc-
cur during the installation.
Problem: Possible cause: Remedy
The modem does not accept
calls.
Automatic call acceptance is deac-
tivated.
Enter the following commands in
the terminal program:
ATS0=2
AT*A1
The key entries are not dis-
played in the terminal program.
The display of the key entries
(echo) is deactivated.

The modem starts dialing after
the dialing command ATD has
been entered and reports the
error “No Dialtone”.
The phone line is interrupted. Check the phone line.
The modem starts dialing after
the dialing command ATD has
been entered and reports the
error “No Dialtone”.
The modem is operated at a PBX.
The PBX requires that a code
number is dialed to establish a
connection
or that the flash function is acti-
vated, before the dialing tone is
heard. The modem, however, is
awaiting a ring back signal al-
ready before the first digit is di-
aled.
After the leading digit was dialed
without a ring back signal, insert-
ing 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 com-
mand or by inserting the charac-
ter > into the dialing string. (See
Chapter 9, command 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 Delay”.
