NSAP Addresses (X.213)
Alternatively to the standard and extended formats the NSAP (Network Service
Access Point) address format is used. The NSAP format is defined in X.213.
Only a few public networks support this format.
The NSAP format has a complex structure. NSAP addresses consist of up to 40
hexadecimal characters.
Two types of NSAP addresses are defined, OSI compliant (indicated by a lead-
ing X) and Non-OSI compliant (indicated by a leading N).

X.25 Routing

To configure X.25 routes you must open the X.25
Routing decisions can be made based on the source link and/or different pa-
rameters included in the call packet.
Calls with extended addresses are not routed, since no routing entry for calls
with a leading "@" exists. Therefore, such calls are refused.
Since some calls may match more than one route, a metric can be used to pri-
oritize routes. A route with the lowest metric value always has higher priority.
