11 Setting Up IM-SSF CAP Phase 2

This chapter describes how to set up an IM-SSF CAP Phase 2 interworking module.

About IM-SSF CAP Phase 2 Setup

The process of IM-SSF CAP Phase 2 setup requires the following:

1. Adding an IM-SSF CAP Phase 2 to your Oracle Communications Service Broker deployment. You can add as many modules of type IM-SSF CAP Phase 2 as you need. See "Adding an IM-SSF CAP Phase 2 to the Service Broker Deployment" for more information.

2. Configuring the IM-SSF CAP Phase 2. See "Configuring an IM-SSF CAP Phase 2" for more information.

Adding an IM-SSF CAP Phase 2 to the Service Broker Deployment

To add an IM-SSF CAP phase 2:

1. In the domain navigation pane, expand the OCSB node.

2. Expand the Processing Tier node.

3. Expand the Interworking Modules node.

4. Select IM Management.

5. On the bottom of the IM Management pane, click New.

6. In the New window, fill out the fields as follows:

   • In the Type list, select IMSSFCAP2.

   • In the Version list, select the required version.

   • In the Name field, enter a name for this module as it should appear in the list of modules. In this field, you can only use lower case letters (a-z), upper case letters (A-Z), numbers (0-9), and underscores (_). If you attempt to use a character which is not allowed, Service Broker displays the error message and prompts you to enter a different name.

7. Click OK.

8. In the notification window that reminds you to commit the changes, click OK.

9. To add the new IM-SSF CAP phase 2 to your deployment, in the Change Center pane, click Commit.

   A new module of type IM-SSF CAP phase 2 is now added to your Service Broker deployment. The new module is displayed in the domain navigation pane under the Interworking Modules node.

Configuring an IM-SSF CAP Phase 2

To configure an IM-SSF CAP Phase 2:

1. In the Change Center, click Lock & Edit.

2. In the domain navigation pane, under the Interworking Modules node, select the newly added IM-SSF CAP Phase 2.

Configuring Media Resources Parameters

The Media Resources subtab enables you to define the media resources that the SSP can connect in order to play announcements.

The table in the Media Resources subtab displays the media resources that are used to play announcements. Each row represents one media resource. When defining a new media resource, you need to specify the fields described in Table 11-7.

Possible values: Yes Connection to the media resource causes the switch to generate answer indication backwards. This opens a media path from the caller to the media resource (bothwayPathRequired). False The media path opens only in the direction from the media resource to the caller. None Default value: Yes

Note:

When an internal media resource is used (CTR), the Address Digits, Nature of Address and Address Numbering Plan Indicator parameters can be set to 'None' in order to instruct the network's session control entity to connect its pre-configured media resource.

Configuring TCAP Parameters

The TCAP subtab enables you to set up parameters of the IM TCAP layer.

Table 11-8 describes configuration parameters in the TCAP subtab.
