SS7 Signaling

The SS7 signaling object is the first object created when configuring SS7 signaling on the 2020 IMG. To configure, right click on the Signaling object and select New SS7. The Redundancy Configuration field within this object will default to Standalone if only one node has been created within the logical node group and SS7 redundancy is not being configured. If SS7 redundancy is going to be configured, and a second 2020 IMG node has been created, the Redundancy Configuration field now allows the user the ability to select either Standalone or Primary. If configuring SS7 redundancy, select Primary in this field and select the ID of the node that will be the Secondary SS7 node. Once configured, the SS7 object that gets created displays whether SS7 redundancy has been configured and what the peer and secondary node ID's are. The 2020 IMG supports creating one SS7 signaling object per 2020 IMG node and up to four SS7 stacks can be created under it.

Note: The labels Primary State and Secondary State do not indicate that the node is the active or standby node. Primary and Secondary only label how the node is configured. If a switchover from primary to secondary occurs, the secondary node is considered the active node and the primary is considered the standby node.

Related Topics and Dependencies

The SS7 Signaling Object is the first object created when configuring stacks, links, routes, etc. Once SS7 Signaling is created, right click and select New SS7 Stack. From here, Linksets, links, and routes can be configured. Once the stack, link-sets, links and routes have been created, the stacks created under the SS7 signaling object will be configurable in the SS7 Channel Group object.

Field Descriptions

Redundancy Configuration

This field specifies the state of the SS7 state machine. Select Primary from drop down menu if the node that the SS7 signaling is being configured on will be the primary node of an SS7 redundant pair. If SS7 redundancy is not being configured, accept the default which is Standalone.

StandAlone (Default) - Select Standalone if SS7 redundancy is not being configured on this node.

Primary - Select Primary if SS7 redundancy is being configured. By selecting Primary, the node that the SS7 signaling is being configured on will be the Primary/Active node of an SS7 redundant scenario. Once the primary object is committed and is considered the primary SS7 node, it cannot be modified. To modify, the physical node will need to be deleted and then re-added.

Note: For the selections of Standalone and Primary to appear in the drop down menu, there must be at least two nodes created under one logical node group.

 

Peer Logical Node ID

If configuring SS7 Redundancy, this field will have a drop down menu displaying all the nodes that are created under the logical node group. Select by Node ID which node will be configure as the secondary/standby node in the SS7 Redundancy scenario. If Standalone is selected in the Redundancy Configuration field then the Peer Logical Node ID field will be shaded green and cannot be modified.

 

 

Monitoring Fields

Primary State

This monitoring field displays the state of the primary SS7 server node.

Secondary State

Displays the state of the standby node. This field defaults to Not Applicable when SS7 redundancy is not being configured.
