Alias and Call Routing Configuration: Alias Configuration Examples

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.

 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.
