14 Setting Up IM-SSF WIN Phase 1

This chapter describes how to set up an IM-SSF WIN Phase 1 interworking module.

About IM-SSF WIN Phase 1 Setup

The process of IM-SSF WIN phase 1 setup requires the following:

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

Adding an IM-SSF WIN Phase 1 to the Service Controller Deployment

To add an IM-SSF WIN phase 1:

In the domain navigation pane, expand the OCSB node.
Expand the Processing Tier node.
Expand the Interworking Modules node.
Select IM Management.
On the bottom of the IM Management pane, click New.
In the New window, fill out the fields as follows:
- In the Type list, select IMSSFWIN1.
- 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 Controller displays the error message and prompts you to enter a different name.
Click OK.
In the notification window that reminds you to commit the changes, click OK.
To add the new IM-SSF WIN phase 1 to your deployment, in the Change Center pane, click Commit.

A new module of type IM-SSF WIN phase 1 is now added to your Service Controller deployment. The new module is displayed in the domain navigation pane under the Interworking Modules node.

Configuring an IM-SSF WIN Phase 1

To configure an IM-SSF WIN phase 1:

In the Change Center, click Lock & Edit.

In the domain navigation pane, under the Interworking Modules node, select the newly added IM-SSF WIN phase 1.

The IM-SSF WIN phase 1 configuration pane contains the subtabs described in Table 14-1.

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 14-5.

Name	Type	Description
Name	STRING	Specifies a name of the media resource.
Alias	STRING	Specifies a unique identifier that applications use to instruct IM-SSF which media resource to connect in order to play announcements. Alias is used by IM-SSF to lookup a media resource details in this table. Aliases are defined in a URI format. For example: mrf.network@domain.com.
Address Digits	STRING	Specifies the digits part of the media resource address. The media resource address is used to set up a connection towards the media resource. Note: when this parameter is not set, the network's session control entity uses a pre-configured media resource to play announcements. In this case, Nature of Address and Address Numbering Plan Indicator should be set to None.
Operation Type	STRING	Possible values: switched_based The media resource is an internal part of the SSP. CCDIR operation is used to set up a connection towards the media. resource. external The media resource is not part of the SSP. ConnectResource operation is used to connect the media resource.

SN Address	STRING	Specifies the value to set in the DestinationDigits parameter of the CONNRES operation. This value is regarded only when SN-IP Configuration parameter is set to SN.

Configuring TCAP Parameters

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

Table 14-6 describes configuration parameters on the TCAP subtab.

Activate Invoke Alarm in Application Layer	BOOL	When the TCAP layer receives an INVOKE, it triggers back PABORT if there is no response. The waiting time period for response is configured in the encoding library. The Activate Invoke Alarm in Application Layer parameter specifies whether or not to activate this timer. Possible values: True False Default value: False
Result Split Length	INT	Specifies the maximum length of the TCAP RESULT message. When the actual length of the message exceeds the specified value, the message is split. Default value: 512
