Configure Message Waiting Indicator - SIP to SS7 Interworking

 

Initial Configuration:

To configure this feature, the IMG must have an initial configuration on it. Before proceeding verify that ClientView has an initial configuration on it. The Logical Node, Physical Node, and Facilities including IP bearer spans must already be configured to proceed. Verify all initial configuring has been accomplished before proceeding. When configuring the MWI feature with SS7 Redundancy, verify you select the SS7 Primary node when configuring the SS7 Stack.

Configure SS7 Stack:

An SS7 stack must be configured.

  1. Right Click on the Physical IMG object in the object tree of ClientView and select New Signaling. A Signaling Pane will get created.

  2. Right Click on the Signaling object just created and select New SS7. An SS7 StandAlone object will get created. See SS7 Standalone Pane for more information on configuring this pane.

  3. Right Click on the SS7 StandAlone object created and select New SS7 Stack. An SS7 Stack Pane will get created. Enter the information needed for your specific network. The first part of configuring the IMG for MWI is to enable SCCP and TCAP signaling in the stack. Select ANSI from drop down menu of both the SCCP and TCAP fields. Feature 1580 is not supported in ITU, only ANSI. See screen capture below.

Note: See SS7 Stack link for more information on configuring the individual fields of the SS7 Stack Pane.

 

Note: If configuring a service such as CNAM or MWI on multiple IMG nodes, the SS7 Stack ID's cannot be configured with the same ID. For example, when configuring an IMG Node 0 with stack ID's 0 and 1 then any other IMG Nodes configured under any Logical Node can not have any of the stacks configured with the same ID's (0 or 1). By doing so, the TCAP services cannot be configured.

 

  1. Right Click on SS7 Stack and select New SS7 Link Set. Enter an Adjacent Point Code. See SS7 Link Set link for more information on configuring the Link Set.

  2. Right Click on SS7 Link Set and select New SS7 Link. Using drop down menus, enter an Interface - Offset, Channel, SLC and any other information regarding the SS7 Link. Select See SS7 Link for more information on configuring the SS7 Link.

  3. Right Click on SS7 Link Set and select New SS7 Route. Enter the DPC. See SS7 Route for more information on configuring the SS7 Route.

  4. Right Click on the SS7 Stack Object created above and select New SCCP/TCAP and the SCCP/TCAP pane gets created. No configuration is done within this pane. This pane will allow you to configure other objects that have to do with SCCP/TCAP. See SCCP/TCAP link for more information on this pane.

  5. Right Click on the SCCP/TCAP object and select New Subsystem Number. Select a Subsystem Number from the drop down menu.

  6. The Subsystem Number Status is by default set to 'Prohibited'. Using the buttons just below the Subsystem Pane, hit 'Allow' and the status will change to 'Allowed'. See Subsystem Number link for more information on configuration of the Subsystem Number Pane.

  7. Right Click on Subsystem Number and select New Adjacent Translator. Select from drop down menu the Adjacent Point Code that will be used for the Message Waiting Indicator. The point codes in drop down menu are point codes from the DPC of the Route ID.
