Creating an ISUP User Part
After you have created your ISUP network, you must create a new ISUP user part. The user part is the con-
tainer for the multiple ISUP interfaces. One user part is required for each protocol variant.
Multiple ISUP user parts can be instantiated within a single ISUP
protocol layer. This allows a user application
to interface with multiple SS7 ISUP protocol variants at the same time. Only one ISUP user part is required
for a specific variant as it can be assigned to multiple ISUP networks.
A user part can easily be seen as a protocol variant that a host application wants to use on the SS7 network.
To create an ISUP user part:
1. Cl
ick Create New Isup Userpart in the ISUP stack configuration window:
