Link-to-Link Call Routing
Link-to-link call routing lets users route all SVC calls coming in on one X.25 link to
another X.25 link. By using X.25 link-to-link call routing, it is now possible to create a
default route for all calls from a specified X.25 link. The alias for the default link-to-link
route can route all calls destined for the same link. On previous versions of AI296,
users had to create an alias for each unique called address.
,
NE1
and
NE2
place calls to
NE3
,
NE4
, and other elements on the
X.25
network. Aliases route calls from
NE1
and
NE2
to the network elements. A link-to-link
call route exists between links 1 and 2, and between links 3 and 4. An incoming X.25
SVC call from
NE1
that does not match an alias in the table would be routed to
link 2
,
and an incoming X.25 SVC call from
NE2
that does not match an alias in the table
would be routed to to
link 4
.
Important: The link-to-link call alias must be at the end of the alias list. If the
link-to-link alias is above an actual destination alias, an X.25 SVC call
will be processed by the default link-to-link alias.
