Procedure
The steps below describe how to configure two stacks on the IMG 2020 as Application Servers and have then communicate with an existing remote Signaling Gateway Server. The procedure below assumes the remote Signaling Gateway Server has already been configured with the information such as Sigtran Links (Associations) to be able to communicate with the Application Servers being configured.
Initial Configuration
Refer to the link Basic Configurations to configure the initial objects that need to be created before proceeding on with the configuration of the M3UA stacks and associations. 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 m3ua stacks and associated functionality.
...
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.
Right click on the SS7 object 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.
Right click on the SS7 Network object and select New SS7 Nodes. The 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.
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.
...
OPC | Click in the OPC field and enter the point code being given to the Application Server Stack ID: 0. In this example, 0-0-7 was selected. |
SCCP | Select ANSI if T1 or ITU if E1 from drop down menu |
M3UA Service Mode | Select Application Server (AS) Mode from drop down menu. |
...
Refer to the SS7 - Stack topic for more information about configuring the rest of the Stack fields.

Field | Description |
Link ID (Association) | The Link ID (Association) is automatically populated with the next available ID. To modify the Link ID click in the Link ID field and select a new ID from drop down menu. |
Primary/Secondary | Select whether the Sigtran Link/Association will be a primary or secondary link. Since SS7 stack redundancy is not being configured, Primary is displayed and cannot be modified. |
Network Appearance | Since this is a single setup, the Network Appearance is not needed. |
Client/Server | Select whether the IMG 2020 will be server or client. In this example the default which is client was accepted. |
Source Port | Enter the Port Number to be utilized. The default port for local and remote Sigtran Links/Associations is 2905. |
Destination Port | Enter the port number of the remote Application Server that the Sigtran Link/Association will be connecting to. The default port for local and remote Sigtran Links/Associations is 2905. |
Local IP 1 | Select which interface (by IP Address) from the drop down list of configured IP addresses on the IMG 2020. This IP will be used for M3UA signaling. |
Remote IP 1 | Enter the IP address of the Remote Signaling Gateway Server interface that the Sigtran Link/Association will be communicating with. In this example, the remote signaling gateway is at IP address 10.129.39.80. |
Local IP 2 | If there is a second interface which would be used for Redundancy select from drop down menu the IP address of the second interface. |
Remote IP 2 | If redundancy is being configured, enter IP address of the remote application servers redundant IP interface. |
Refer to the M3UA Sigtran Link topic for more information on each of the individual fields.

Right click on SS7 Application Server Stack ID:1 created above and select New M3UA Remote SG. The Remote Signaling Gateway is the same Gateway as configured above except the Routing Context for this stack will be set to 16. This is what the Remote Signaling Gateways routing context is set to as well.
Right click on the Remote SG object and select New Sigtran Link (Association). Configure the Sigtran Link/Association pane as displayed below. Note that since this link is connected to the Remote Signaling Gateway stack that is already configured, the Remote IP address field will have the same IP address as above.
The Source and Destination Ports were modified to be a different port than the ports configured above. The Source and Destination Ports needed to be different than that configured on the first Application Server. Refer to the screen capture below.
Right click on Stack ID:1 being configured and select New Destination. Enter the Destination Point Code of the first remote Application Server configured in this procedure. This is the point code of the initial M3UA stack. Refer to the M3UA SS7 Destination topic and Web GUI Page below for more information.

The M3UA DPC is the Point Code of the first Application server stack. |
...
Right Click on the SS7 Destination object of the application server stack ID:0 and select New SS7 Group. Select the correct ISUP Profile from the ISUP Profile drop down menu. Refer to the ISUP Group topic for more information on configuring this object.
Right click on the SS7 ISUP Group object and select New SS7 Circuit Group. Select the starting and ending spans that will be part of this circuit group that will carry the CICs. In this example Span 0 Channels 0-23 was selected.
Enter a Starting CIC number in the Starting CIC field.
Create CICs for the second Application server as well. Right Click on the SS7 Destination object of the application server stack ID:1 and select New SS7 Group. Select the correct ISUP Profile from the ISUP Profile drop down menu. Refer to the ISUP Group topic for more information on configuring this object.
Right click on the SS7 ISUP Group object and select New SS7 Circuit Group. Select the starting and ending spans that will be part of this circuit group that will carry the CICs. In this example Span 1 Channels 0-23 was selected.
Enter a Starting CIC number in the Starting CIC field. Verify the starting CIC in this CIC Group does not overlap the numbering of the CIC Group created for Application Stack ID:0
Right click on the Dialogic object and select New Routing Configuration. The Routing Configuration object is a container or Parent object and no configuration is needed here. Refer Routing Configuration link for more information.
Right click on Routing Configuration just created and select New Channel Groups. The Channel Groups object is a container object as well and no configuration is needed here. Refer to the Channel Groups link for more information.
Right click on the Channel Groups object and select New Channel Group. Enter a name for the Channel Group and select SS7 as the Signaling Type. See Channel Group link for more information on configuring the SS7 Channel Group.
Right click on the Channel Group just created and select New Circuit Group. In the Starting and Ending Span/Channel fields, select the Spans that were configured in the 1st ISUP group configured. (Span 0, Channels 0-23)
Right click on the Channel Groups object again and select New Channel Group. Enter a name for the Channel Group and select SS7 as the Signaling Type. See Channel Group link for more information on configuring the SS7 Channel Group.
Right click on the Channel Group just created and select New Circuit Group. In the Starting and Ending Span/Channel fields, select the Spans that were configured in the 2nd ISUP group configured. (Span 1, Channels 0-23).
The Channel Group object will have a yellow exclamation point for an Icon. This indicates the configuration needs to be sent to the IMG 2020. Click on the Download Resource Tables button to send the configuration to the IMG 2020.
Once configured, the CIC's will come In Service. Verify this by viewing the Object Table below the Circuits object pane.
