VI.11.1.2. ProntoNetLC SLAVE operation
If ProntoNetLC works as SLAVE, the entry or exit to the backup mode will be
guided by different criterions than the defined ones in the MASTER mode. First of
all, it is necessary that the Backup option be enabled.
The unit will work by default in IP or X21 mode monitoring the state of the ISDN
line continuously. If an incoming call is detected, the unit will switch to backup
mode automatically. If the call hungs up, the unit will pass to work in IP or X21
mode again.
During the backup phase the ProntoNetLC SLAVE goes on sending coded audio
through the main line in order for the ProntoNetLC MASTER can detect that the
line has been recovered.
It is also possible to program call filters in the ProntoNetLC SLAVE in order to
avoid the unit answering unwanted calls.
