NUA Mappings parameters
Protocol switch NUA mappings allow you to redirect specified NUAs to alternative NUAs for
switched X.25 calls. Up to 20 NUA In to NUA Out mappings are available. These mappings alter
the called NUA field in any X.25 call. The comparison uses tail matching, so only the rightmost
digits in the NUA are compared with the table entry.
This page displays a table with four columns in which you can specify the NUA In values,
corresponding NUA Out values, to which interfaces the mappings should be applied, and
whether the mapping should apply if the router is making the call, receiving the call, or both.
For example, if the called NUA is 123456789345 and there is an NUA In table entry of 9345, with
Called/Calling set to either Both or Called, this will match, and the entire called NUA will be
replaced with the corresponding NUA Out entry. In each case, the interface type to which the
mapping applies can be selected from ANY, LAPD, LAPB0, LAPB1, LAPB2, or XOT.
