Toolpack:Creating an ISUP User Part B

Applies to version(s): v2.8.

Once you have created your ISUP network, you must create a new ISUP user part.

The user part is the container for the multiple ISUP interfaces. One user part is required for each protocol variant. A user part can be seen as a protocol variant that a host application wants to use on the SS7 network.

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. In addition, only one ISUP user part is required for a specific variant as it can be assigned to multiple ISUP networks.

To create an ISUP user part:

1- Click ISUP in the navigation panel.

2- Select the ISUP stack

3- Click Create New Isup Userpart in the ISUP stack configuration window:

4- Configure the new ISUP user part:

• Enter a name for the user part
• Select a protocol variant (depending on location)
• Select an MTP3 sub service field (the same that was previously set for MTP3)
• Select an address indicator type
• Select a Numbering Plan
• Click Create

5- Verify that the "IsupUserpart was successfully created" message appears
