Not for INSYS Modem LL. 

In phone networks, DTMF is used to dial a remote terminal. To 
enable switching centers to distinguish between voice and 
DTMF digits, these digits are created from two unique frequen-
cies, which cannot be created by people in this form. These 
tones are created with the keys of fixed network and mobile 
phones. 
 
With the help of DTMF (Dual Tone Multiple Frequency), the 
status of inputs and outputs can be queried. 

Activate DTMF mode 
 
Deactivate DTMF mode 
 
Save settings (optional) 
 
After the activation the modem is set into receive mode for in-
coming calls.  
 
 
At the start of the DTMF mode connection, the PIN number is 
prompted. The default setting is “0000”. 
 
The PIN consists of 4 digits and may be changed any way. The 
change is immediately stored in the permanent memory. First, 
the previous PIN must be entered, then the new PIN. Afterwards, 
the new PIN must be entered once more for confirmation.
