Creating an SCCP SSN

Applies to version(s): v2.5, v2.6, 2.7

Now that you have configured an SCCP Route, you can add SCCP Sub-System Number (SSN) on the route.

SCCP Sub-System Number are used to identify applications of this route's DPC. SCCP managament will maintain the availability state for each SSN associated to this route's DPC. The SSN management status affects the routing decision. If a peer SSN is unavailable, the SCCP stack will try an alternate DPC/route.
