Configuration - Network > Protocol Switch > NUA Mappings
Protocol switch NUA mappings allow you to redirect specified NUAs to alternative NUAs for
switched X.25 calls. Up to twenty “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 that 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 unit 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”, then 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”.
