In case you configured a PPP connection for 'Dial on demand',
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).
If a PPP session is up, it can issue Link Control Protocol (LCP)
echo requests at regular intervals and expects LCP echo replies in
return.
This checkbox allows to turn on/off LCP echo request/replies by
respectively setting (n), or clearing the flag.
By default LCP echo is on (i.e. flagged n), allowing the local PPP
peer to detect communication errors, resulting in closing of the
PPP session.
The STPro features two authentication protocols to be used:
Challenge Handshake Authentication Protocol (CHAP).
"
Password Authentication Protocol (PAP)
"
Per default the STPro will negotiate CHAP with the BroadBand
RAS (BBRAS) as it is the safest authentication protocol. However,
PAP will be allowed, if needed.
Setting the PAP flag (n) will force the STPro only to negotiate PAP
with the BBRAS.
Address and Control field COMPression (ACCOMP), sometimes
abbreviated as ACCM, is by default enabled, i.e. flagged (n).
This option flag should not be cleared, except in special
circumstances, i.e. where the remote PPP server expects to see
HDLC like framing (FF03 imposed to the PPP packet).
