When the Nautica 200 receives a call, the calling switch
sends the ISDN number it is calling as part of its data.
This is the CLI number that is matched by this
parameter.
There are three CLI values that you can set, depending
on the level of security required.
• Info: With Info set, when a call comes in CLI is
ignored and the call passes straight to PAP/CHAP
authentication.
The receiving unit challenges the sending unit to
identify itself. The sending unit responds with its
PAP/CHAP passwords. The receiving unit matches
this information against the passwords set up on an
existing path. If the passwords are not matched, the
call is dropped. If the passwords do match, then the
call is accepted.
• Auto: With this value set for CLI, an incoming call
is automatically matched against an existing path
that contains the CLI number. If the path exists then
authentication proceeds.
The receiving unit matches the incoming number
against an ISDN number in a path and then matches
the PAP/CHAP passwords on that path. If the
passwords are authenticated the call is allowed; if
they are not authenticated, the call is dropped.
If no path is found for the incoming number, the
receiving unit challenges the sending unit to identify
itself. The sending unit responds with its NodeID
and its passwords. The receiving unit matches the
NodeID against a path name and then matches the
passwords. If no match is found the call is dropped;
if the passwords do match, the call is accepted.
• Force: With Force set as the value for CLI, an
incoming call must match against an ISDN number
set up on a path in the receiving unit. If no match is
made the call is immediately dropped. If a match is
found then authentication will take place.
