Configuring SS7 with Remote Nodes

The 2020 IMG can be configured so that the SS7 stacks and links are configured on a primary SS7 server node, and the CIC's are configured on several remote nodes (See Diagram Below). In this scenario, the CIC's that are configured on the remote nodes will be controlled by the SS7 stacks and links that are configured on the SS7 server node. The SS7 server/remote node network must all reside under one logical group. The procedure below describes how to configure this setup using ClientView.

Procedure

Follow procedure below to configure an SS7 server node and then configure the SS7 remote nodes.

 

Initial configuration on SS7 primary server node

Before configuring the SS7 functionality on the server node, the basic objects must first be configured. Refer to the Basic Configurations topic for information on configuring the initial functionality needed for most configurations.

 

Configure a 2020 IMG as the Primary SS7 server node

  1. Create the Signaling entry object. Right click on the Physical Node that will be the Primary SS7 node and select New Signaling. A signaling object will get created. The signaling object created is a parent object to multiple signaling protocols and no configuration is needed here. Refer to the Signaling topic for more information on this topic.
  2. Right click on the Signaling object created and select New SS7. An SS7 signaling pane will appear. In this procedure, SS7 Redundancy will NOT be configured. Leave the Redundancy Configuration field set to StandAlone. Refer to the SS7 Signaling topic for more information on this object.
  3. Create the SS7 signaling stacks. Right click on the SS7 Primary object and select New SS7 Stack. In the OPC field, enter the point code that will be assigned to the SS7 stack being created. For more information on configuring the SS7 object pane, refer to the SS7 Stack topic.

  4. Configure the SS7 Link Set under the stack created by right clicking on the stack and select New SS7 Link Set. Enter the point code of the adjacent SS7 stack that this stack will be communicating with. Refer to the SS7 Link Set topic for more information on configuring the individual fields.

  5. Configure an SS7 Link by right clicking on the SS7 Link Set just created and select New SS7 Link. Select Node and Span/Channel that the link will reside on. See screen capture below. For more information refer to the SS7 Link topic.

  1. Right click on the SS7 Link Set created and select New SS7 Route. Refer to the SS7 Route topic for information on configuring the individual fields.

 

Initial configuration on SS7 remote node

Before configuring the CICs etc on the remote SS7 node, the basic objects must first be configured. Refer to the Basic Configurations topic for information on configuring the initial functionality needed for most configurations.

Note: The remote node needs to be created under the same logical node group as the SS7 server node.

 

Configure CICs on the remote node.

  1. Right Click on the Dialogic IMG EMS object and select New Routing Configuration. There is no configuration achieved in this object. Under the Routing Configuration object, the Channel Groups can get created. For more information refer to the Routing Configuration object.

  2. Right Click on Routing Configuration and select New Channel Groups. The Channel Group main object will get created. Under this object, multiple channel groups can be created. For more information refer to the Channel Groups object.

  3. Right Click on Channel Groups object and select New Channel Group. Enter a name for this Channel Group and verify SS7 signaling is displayed in the Signaling Type field. For more information on this object, refer to the Channel Group topic.

  4. Right Click on the Channel Group just created and select New ISUP Group. An ISUP Group Pane will get created. In the OPC-DPC field, select from drop down menu the node that holds the SS7 stack created above. See screen capture below.

For more information on this object pane, refer to the ISUP Group topic

  1. Configure the remote CIC's that will be controlled by the stack selected in previous step by right clicking on the ISUP group created and select New Circuits. A Circuits Pane will appear as shown below.

Once finished with configuration above, a standalone node with SS7 stacks, links, and routes was created. A second node was then created and all the SS7 CIC's were assigned to the second node. In this scenario, the SS7 stacks and links created on the standalone node will control the CICs that were created on the second remote node. Below is screen capture of the configuration tree for the procedure above.
