DELTA LOGIC ACCON-MPI-Modem 56k User Manual page 18

Password protection and call-back
Go to the tab »Access Protection«.
Figure 8: Access Protection
There you can create three different users including call-back number
and password. The user »ADMIN« is the only one who has the right to
change all settings in the adapter including the settings of the other
users. The other two users can only change their own password and call-
back number. If a call-back number is set, the ACCON-MPI-Modem 56k
always uses this number to call back if the respective user logs in.
If you enter a wrong call-back number for the user »ADMIN« the ACCON-
MPI-Modem 56k cannot be parametrized via a remote connection any
more. In this case you can only change the call-back number directly at
the device (microswitch position »Ext.«)!
