With password set the modem is protected from unauthorized access 

• 

for incoming data connections 

• 

for remote control 

• 

for security callback 

When the modem answers an incoming call the message “CONNECT” is followed by the 
messages “SECURITY CALLBACK” and “REMOTE PASSWORD:”. 

• 

If the password is wrong the modem immediately disconnects and stops an unau-
thorized access. 

• 

If the password is correct the modem reports "OK" to the calling terminal, disconnects 
and dials the phone number specified after 10 seconds. Up to 3 call attempts are exe-
cuted with 10 seconds breaks in between. 

• 

2 seconds after the connection the message “CALLBACK IN PROGRESS” is sent by the 
calling modem and the serial line is released for a standard data connection. 

Outgoing calls are not influenced by the security callback functionality.
