The 'Mode' field allows you to configure how a PPP session is
opened.
Three options are available:
Dialin
The PPP session is opened manually by clicking next
to the PPP connection in the 'Dialin' page.
Alwayson
After the AST570 is powered and finished its Power On Self
Test (POST) successfully, the AST570 automatically tries to
open a PPP session for the PPP entry.
Dialondemand
The PPP session is opened automatically for a limited period
of time. The opening of the session is triggered by the arrival
of packets at a/the AST570 Ethernet port, to be sent over the
PPP entry.
Note : By default one PPPoA connection is configured as 'Dialin' (i.e. PPP),
another as 'Alwayson' (i.e. PPP2 ).
In case you configured a PPP connection for 'Dialondemand',
the 'Idle Time Limit' box allows you to specify the time after which
an opened, but unused PPP session is closed.
If left free, the idle limit time is infinite (i.e. the PPP session will
never be closed).
