Configuring the SS7 Card

This procedure describes configuring an SS7 card.

Before you begin

The signaling method for a T1 and/or E1 spans must be set to: clear channel. You must obtain the following:

• SS7 user part licenses

• Originating, adjacent and destination point codes

• A CCS I/O card is required to support redundancy, SS7 over a CSP ring or SCCP/TCAP.

• An IP address is required for SCCP/TCAP configuration on each SS7 card.

• An Ethernet connection is required for each SS7 card over a CSP ring.

• Before configuring SS7 links, you must first assign spans on
T-ONE, and E-ONE, J-ONE cards.

You must have a node view window open in configuration mode. If you set up redundant SS7 cards place them in adjacent card slots. You may configure four stacks per SS7 card; each stack has an individual point code (OPC).

Important! When using SS7 PQ cards in either a single node or a multi-node system you may configure a total of 3000 physical and virtual CICs, if both ISUP and SCCP/TCAP are to be configured for this system.

Information Source

Please refer to the SS7 information contained in the API Reference and the Developer’s Guide: Common Channel Signaling.

Configuring SS7

Use the following configuration sequence to bring SS7 signaling links and voice circuits in service. The steps below are used for an SS7 PQ card or SS7 Series 3 card. More details are provided about each step following the table.

Step | Action
--- | ---
1 | Assign and configure spans
2 | Configure SS7 license
3 | Configure SS7 cards
4 | Configure Signaling Stacks
5 | Configure Signaling Link Sets
6 | Configure Signaling Links
7 | Configure Signaling Route(s)
8 | Assign Voice Circuits (CICs)
9 | The following entities must be brought in service in this order and messages must sent separately for each: 1. Spans 2. CICs 3. Signaling links

Configuring the SS7 Card

The following steps guide you through the initial sequence of configuring an SS7 Card. If your card is already configured and you want to change parts of that configuration, please look for the appropriate information in this procedure. To modify any of these SS7 configuration settings, click on the entity you want to modify.

To invoke the SS7 Card Configuration dialog box, do one of the following:

• Double-click the SS7 card in the node view window.

• Right-click the SS7 card in the node view window and select SS7 Configuration from the drop-down list.

• Select the SS7 card, go to the Configuration menu and select Card®SS7 Configuration.

The Viewing SS7... dialog box opens. See the next screen shot.

Important! In a multi-node system, you can have up to four SS7 stacks in the entire system (stack IDs 0-3).

3 Select the Module Type and Module Variant from the drop-down lists for the Modules. The Module Variant must be the same for all modules in one Stack ID.

4 Click the button: When ANSI module variants are selected, the OPC (ANSI) dialog box opens. When other module variants are selected, the OPC dialog box for the selected variant opens.

5 Enter the Originating Point Code (OPC). The OPC must be a numeric value. For example, an originating point code would be entered as 158 77 99. To change the default format for entering point codes, see Setting a Point Code Format. For more details, see the section: "SS7 Point Codes" in the Basics of SS7, Chapter 2, Developer’s Guide: Common Channel Signaling.

To change the default format for entering point codes, see Setting a Point Code Format. For more details, see the section: "SS7 Point Codes" in the Basics of SS7, Chapter 2, Developer’s Guide: Common Channel Signaling.

5 Click OK.

6 Click OK to close the dialog box. The SS7 Card view shows the stack information. The configuration data shown in the next screen shot is example data.

7 Next, you must configure the SS7 Link.

SS7 Link Configuration

1 Before configuring SS7 links, you must first assign spans on T-ONE, E-ONE, and J-ONE cards.

To invoke the SS7 Link configuration dialog box, do one of the following:

• Right-click the Link Set entry in the view and select SS7 Link Configuration from the menu.

• Select the Link Set entry in the view and go to the Configuration menu. Select SS7®SS7 Link Configuration.

This opens the Configure SS7 Link dialog box.

2 Specify the Link ID by selecting a value from the drop-down list.

3 Specify the Span by selecting a value from the drop-down list.
