Called NUA field does not match LAPB 0 NUA, it checks for a match with LAPB 1 NUA and if
there is a match, sets the outgoing interface to LAPB 1.
If the Called NUA field in the calling packet matches neither the LAPB 0 NUA or LAPB 1 NUA
parameters then the outgoing interface is set to the interface specified by the relevant Switch from
parameter.
If the call is being switched over LAPB 0 the unit then sets the Called NUA to the TE NUA (LAPB
0) value. If the call is being switched over LAPB 1 the unit then sets the Called NUA to the TE
NUA (LAPB 1) value.
