In the following some questions are described, which – from experience – may occur dur-
ing 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: 

AT*A1 

The key entries are not dis-
played in the terminal program. 

The display of the key entries 
(echo) is deactivated. 

Activate the echo with ATE1. 

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 De-
lay”.
