is not being used, i.e. if data is no longer being sent, to help you save costs.
Block after Connection Failure
You use this function to set up a waiting time for outgoing connection attempts after which
your device's connection attempt is regarded as having failed.
Authentication
When a call is received on ISDN connections, the calling party number is always sent over
the ISDN D-channel. This number enables your device to identify the caller (CLID),
provided the caller is entered on your device. After identification with CLID, your device can
additionally carry out PPP authentication with the connection partner before it accepts the
call.
Your device needs the necessary data for this, which you should enter here, for all PPP
connections. Establish the type of authentication process that should be performed, then
