This chapter describes how to set up an IM-SCF INAP CS-1 interworking module.
The process of IM-SCF INAP CS-1 setup requires the following:
Adding an IM-SCF INAP CS-1 to your Oracle Communications Service Controller deployment. You can add as many modules of type IM-SCF INAP CS-1 as you need. See "Adding an IM-SCF INAP CS-1 to the Service Controller Deployment" for more information.
Configuring the IM-SCF INAP CS-1. See "Configuring an IM-SCF INAP CS-1" for more information.
To add an IM-SCF INAP CS-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 IMSCFCS1.
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-SCF INAP CS-1 to your deployment, in the Change Center pane, click Commit.
A new module of type IM-SCF INAP CS-1 is now added to your Service Controller deployment. The new module is displayed in the domain navigation pane under the Interworking Modules node.
To configure an IM-SCF INAP CS-1:
In the Change Center, click Lock & Edit.
In the domain navigation pane, under the Interworking Modules node, select the newly added IM-SCF INAP CS-1.
The IM-SCF INAP CS-1 configuration pane contains the subtabs described in Table 5-1.

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 5-8.
Table 5-8 IM-SCF INAP CS-1 Media Resource Definition Fields
Name | Type | Description |
---|---|---|
Name |
STRING |
Specifies a name of the media resource |
Alias |
STRING |
Specifies a unique identifier that applications use to instruct Service Controller which media resource to connect in order to play announcements. 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'. |
Nature of Address |
STRING |
Specifies the NatureOfAddress part of the media resource address. The media resource address is used to set up a connection towards the media resource. Possible values:
Default value: SUBSCRIBER_NUMBER |
Address Numbering Plan Indicator |
STRING |
Specifies the NumberingPlanInd part of the media resource address. The media resource address is used to set up a connection towards the media resource. Possible values:
Default value: ISDN |
Operation Type |
STRING |
Possible values:
Default value: internal |
Service Interaction Indicators |
STRING |
Specifies the ServiceInteractionIndicators parameter in the ConnectToResource operation. Provide the value of the Service Interaction Indicators parameter as a hex string. For example, a two octet long string is represented as 03A5. If you leave this parameter empty or set it to "none", IM-SCF does not add ServiceInteractionIndicators to ConnectToResource. |
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.The TCAP subtab enables you to set up parameters of the IM TCAP layer.
Table 5-9 describes configuration parameters on the TCAP subtab.
Name | Type | Description |
---|---|---|

INT |
Specifies the time period in seconds that the IM waits for possible REJECT. The timer starts when sending INVOKE for class 1-3 operations. |
Application Part Guard Timer |
INT |
Specifies the PSM timer, which is a timer for incoming operations. The PSM timer defines the maximum time in seconds that the application (TC-User) has to respond to incoming INVOKE messages. |
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:
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. |
The Monitoring tab enables you to define how Runtime MBeans and notifications operate for an IM-SCF.
