Configure SS7

The SS7 Configuration procedure creates an SS7 signaling stack along with link sets, links, destinations, and routes. Once the SS7 Network is created, an SS7 Channel group along with its ISUP group and CICs can be configured. The procedure below displays the basic steps needed to configure each object. Within each step is a link to the object being configured. The link will have a more in depth description of each field within that object and the information can be used to determine configurations for your local network. Follow procedure below to configure a basic SS7 Signaling scenario. Below is a Quick Start diagram displaying the objects.

Configure SS7 Signaling and SS7 Network

When configuring SS7 signaling, an SS7 Network is created. The first two objects are the SS7 Signaling and SS7 Network objects. Follow the instructions below to create these objects.

1. Right click on the Dialogic object and select New SS7. The SS7 object is a parent or container object and no configuration is needed within this object. Refer to the SS7 - Signaling topic for more information.

2. Right click on theSS7object and select New SS7 Network. Select a Network ID from the drop down menu. Refer to the SS7 - Network topic for more information on this object.

3. Right click on the SS7 Network object and select New SS7 Nodes. The SS7 Nodes object is a parent or container object and no configuration is needed in this object. Refer to the SS7 - Nodes topic for more information on this object.

4. Right click on the SS7 Nodes object and select New Primary Node. Within the Primary Node object select from the drop down menu which node will be utilizing the SS7 network that is being created. Refer to the SS7 - Nodes - Primary Node topic for more information on this object.

Configure SS7 Stack

Configure the SS7 signaling stack and enter its Originating Point Code. Follow procedure below.

Note: Before proceeding, verify that the Basic Configurations topic has been completed. The Basic Configurations topic sets up objects such as T1/E1 Profiles, T1/E1 DS-1's and ANSI/ITU ISUP Group profiles needed prior to Configuring the SS7 stack and associated functionality.

Right click on the SS7 Network object and select New SS7 Stack. The Stack ID is automatically populated with next available number. In the OPC (Originating Point Code) field enter the point code of the SS7 Stack being configured. Refer to the SS7 - Stack topic for more information.

Configure SS7 Link Set

A signaling link set is an abstract path between the IMG 2020 and an APC (Adjacent Point Code). Within each link set, multiple physical signaling links can be added. A signaling stack must be assigned to all links in a link set. A typical configuration consists of two link sets. When configuring multiple SS7 stacks, the Link Set ID's assigned to each signaling stack must be different. For example, if Link Set ID is assigned to Stack 1, it cannot also be assigned to Stack 2.

1. Right click on the SS7 Stack and select New SS7 Link Set. The link set ID is automatically populated with the next available ID.

2. In the APC (Adjacent Point Code) enter the point code to which this link set will be connected. The format of the APC needs to follow the format given to the OPC. For example if the OPC is ITU 97, which follows the format 3-8-3, the APC should also be running ITU 97 and follow the 3-8-3 format. For more information on configuring the Link Set object refer to the SS7 - Link Set topic.

Configure SS7 Link

An SS7 Signaling Link is a point-to-point connection between two SS7 point codes (For example: A IMG 2020 and an STP). The Signaling Link is configured under the Signaling Link Set. The place holder assigns a physical location in the IMG 2020 (timeslot) and a previously configured Signaling Link Set to a Signaling Link. When configuring multiple stacks, the Link ID's assigned to each signaling stack must be different. For example, if Link ID:1 is assigned to Stack 1, it cannot also be assigned to Stack 2.

1. Right click the desired SS7 Link Set and select New SS7 Link. The Link ID field is automatically populated with the next available ID.

2. The BDN Node field will display the node created under the SS7 Nodes object. This node will be associated with the link being created.

3. In the Span and Channel fields, select the DS-1/DS-0 that the link will be created on. The Span and Channel fields have a  drop-down menu which includes all the DS-1's/DS-0's available on the specific node selected. By default the first available DS-1/DS-0 is displayed. For more information on the individual fields in the SS7 Link pane refer to the SS7 - Link Set - Link topic.

Configure the Destination

The SS7 Destination object communicates to the stack what the Destination Point Code of the SS7 endpoint is. The SS7 Destination is termed as the endpoint in an SS7 network and is not considered any of the signaling transfer points the SS7 signaling passes through to get to the endpoint. Follow procedure below.

1. Right click on the SS7 Stack again and select New Destination. The Destination ID is automatically populated and cannot be modified.

2. Enter the point code of the endpoint in the DPC field.

Refer to the SS7 Destination  topic for more information on this object.

Configure SS7 Routes

The path the SS7 signaling messages pass going from the OPC (Originating Point Code) to the DPC (Destination Point Code) is the SS7 Route. When configuring multiple SS7 stacks, the Route ID's assigned to each signaling stack must be different. For example, if Route ID:1 is assigned to Stack 1, it cannot also be assigned to Stack 2.

1. Right click on the Destination object and select New SS7 Route. The SS7 Route pane appears. The Route ID field is automatically populated with the next available ID.

2. Select the Linkset that will be used from the drop down menu of the Linkset field.

3. Select the priority to assign to the route when there are multiple routes to the same destination.

4. Use the Comments field to enter a meaningful name to identify the route. For more information on the SS7 Route pane refer to the SS7 - Destination - Route topic.

Configure the SS7 ISUP Group and Circuit Group (CICs)

Under the Destination object, multiple ISUP Groups can be created. The ISUP Groups created will be linked to the Channel Group object which will be completed in the next section. Follow procedure below which creates an ISUP Group.

1. Right click the Destination object again and select New SS7 Group. Select from the drop down menu of the ISUP Profile field which ISUP Profile will be used in the ISUP Group being created. Refer to the ISUP Group topics (SS7 - Destination - ISUP Group - ANSI and SS7 - Destination - ISUP Group - ITU) for more information on configuring each of the separate fields within this object.

2. Right click on the SS7 Group created and a list of advanced ISUP Group parameters will appear. Select one or more parameters to be added to the ISUP Group being created. Refer to the topic for information on each of the individual parameters.

3. Right click on the SS7 ISUP Group object again and select New SS7 Circuit Group. In the Node Name field, select the Node from which the DS-1's and DS-0's will be used to create the CICs. The nodes in the list will be from the list of nodes under the SS7 Nodes object created earlier.

4. Select from the drop down menus of the next four fields, the Starting and Ending Spans/Channels (DS-1's/DS-0's). The DS-1/DS-0's in the drop down lists will be all the available DS-1's/DS-0's available on the node selected above.

5. Enter a Starting CIC number into the Start CIC field. Refer to the SS7 - Circuit Group under Signaling topic for more information on this topic.

Note: Once the circuit groups have been created with their associated CICs, it is expected that the CICs will come into service at this time. The CICs will not come into service until after the Circuit Group object, that is created under the Channel Group object, is created and configured.

Configure SS7 Channel Groups and a second SS7 Circuit Group

Configure an SS7 Channel Group to communicate with the local SS7 network.

1. Right click on the Dialogic object and select New Routing Configuration. The Routing Configuration object is container object and no configuration is needed. Refer to the Routing Configuration topic for more information on this object.

2. Right Click on the Routing Configuration object and select New Channel Groups. The Channel Groups object is a container object for multiple channel groups. No configuration is needed here. For more information refer to the Channel Groups topic.

3. Right click on the Channel Groups object and select New Channel Group. In the Name field, either accept the default name entered or enter a name that will identify this specific Channel Group.

4. Select SS7_ISUP from the drop down menu in the Signaling Type field. For more information on configuring the SS7 Channel Group refer to the Channel Group topic.

5. Right Click on the SS7 Channel Group created and select New Circuit Group. As described in the Configure the SS7 ISUP Group and Circuit Group (CICs) section above, select the node and DS-1'S/DS-0's that will be used for this circuit group. The selections made should mimic the selections made in the section above. Refer to the ISDN Circuit Group under Channel Group topic for more information on this object.
