16 Setting Up IM-SSF AIN 0.1

This chapter describes how to set up an IM-SSF AIN 0.1 interworking module.

About IM-SSF AIN 0.1 Setup

The process of IM-SSF AIN 0.1 setup requires the following:

  1. Adding an IM-SSF AIN 0.1 to your Oracle Communications Service Broker deployment. You can add as many modules of type IM-SSF AIN 0.1 as you need. See "Adding an IM-SSF AIN 0.1 to the Service Broker Deployment" for more information.

  2. Configuring the IM-SSF AIN 0.1. See "Configuring an IM-SSF AIN 0.1" for more information.

Adding an IM-SSF AIN 0.1 to the Service Broker Deployment

To add an IM-SSF AIN 0.1:

  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 IMSSFAIN01.

    • 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 AIN 0.1 to your deployment, in the Change Center pane, click Commit.

    A new module of type IM-SSF AIN 0.1 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 AIN 0.1

To configure an IM-SSF AIN 0.1:

  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 AIN 0.1.

    The IM-SSF AIN 0.1 configuration pane contains the subtabs described in Table 16-1.

Separate multiple TDPs with a comma. For example: 3607=R, 3616=N


Configuring Operation Propagation Parameters

The Operation Propagation parameters subtab enables you to define whether the IM-SSF processes operations on its own or propagates these operations to another module.

The table on the Operation Propagation subtab displays a list of operations. Each row represents one operation for which you define whether IM-SSF processes this operation or propagates the operation to another module. When configuring a new operation, you need to specify the fields described in Table 16-5.

Possible values:

  • Yes

    The switch disconnects a call immediately after completing playing announcement.

  • No

    The switch does not disconnect a call immediately after completing playing announcement.

Default value: Yes

Answer Indication

BOOL

Specifies whether a switch sends Answer message to the calling party upon connection to the media resource.

Possible values:

  • Yes

    Connection to the media resource causes the switch to generate answer indication towards the calling party. This opens a media path from the caller to the media resource (bothwayPathRequired).

    The media path opens only in the direction from the media resource to the caller.

  • None

Default value: Yes


Configuring TCAP Parameters

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

Table 16-7 describes configuration parameters on the TCAP subtab.

Default value: 1000

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.

Default value: 200

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


Configuring Monitoring Parameters

The Monitoring tab enables you to define how Runtime MBeans and notifications operate for an IM-SSF. For more information about configuring monitoring, see "Configuring Service Broker Monitoring" in "Monitoring Service Broker Using Runtime MBeans" in Oracle Communications Service Broker System Administrator's Guide.
