Configure IMG as AS Server

 

 

dg_sigtran_as_network.png

 

 

Procedure:

The steps below describe how to configure the IMG 1010 as an Application Server. The diagram above shows multiple application servers but this procedure explains how to configure only one. The procedure will not describe the initial few steps such as configuring facilities or profiles. This type of information is assumed to be already configured however links to some of these types of configuration will be provided.

 

Initial Configuration:

  1. Configure Logical and Physical IMG Node. See Logical IMG and Physical IMG links.

  2. Configure the Network Interfaces

  3. Configure T1/E1 facilities. See Configuring T1/E1 Bearer Profile and Configuring T1/E1 Bearer Spans or Configuring T1/E1 Signaling Spans.

  4. Configure IP Bearer Profiles and IP Bearer Spans/VoIP Modules.

 

Configure M3UA Application Server Stack:

In the procedure below the Signaling Gateway Servers that the IMG 1010 Application Server stack will connect to are third party Signaling Gateway Servers that are already configured. This procedure will not explain how to configure them but just how to configure the IMG 1010 Application Server stack to connect/communicate with them.

 

  1. Right click on the IMG Name object in ClientView and select New Signaling. The Signaling Pane will appear. There is no configuration needed in this pane. This is a placeholder to be able to create SS7 signaling stacks. See Signaling link for more information.

  2. Right Click on the Signaling object and select New SS7. An SS7 signaling pane will appear. Select whether this configuration will be a standalone or Redundant system. In this example, standalone was selected. See SS7 Signaling link.

  3. Right Click on the SS7 Signaling object created and select New SS7 Stack. An SS7 Stack 0 ClientView Pane will appear. Configure the following parameters to configure Stack 0 as an Application Server stack.

 

See SS7 Stack for more information about configuring the rest of the Stack fields. (Non M3UA related)

  1. Right Click on the SS7 Stack 0 created above and select New Remote Signaling Gateway (SG). The remote Signaling Gateway is an external Signaling Gateway that the Application Server Stack on the IMG will communicate with. Configure the Remote SG Pane. The Routing Context of the Remote Signaling Gateway is 15 as shown below. See Below

Note: As of 10.5.3 SP6 the Routing Context parameter can be an empty value when Remote SG or Remote AS is configured.

 

  1. Create the St-links. Right Click on the Remote SG object just created and select New Sigtran Link. A Sigtran Link ClientView Pane will appear as shown below. Fill in the fields as needed. See M3UA Sigtran Link for more information.

  1. Right Click on the Signaling Gateway Stack being configured and select New DPC Route. Information such as Route ID, Destination Point Code, and Remote SG need to be configured in this pane. See M3UA DPC Route link and Clientview Pane below for more information.

  1. This example has two Application Server stacks configured on the same IMG 1010. In the first section of this procedure, the first Application Stack was created. The second portion of this example is to create the second Application server stack and configure it to communicate with the first. The next few steps describes how to create the second Application Server. Right Click on the SS7 Signaling object and select New SS7 Stack. An SS7 Stack 1 ClientView Pane will appear. Configure the following parameters to configure Stack 1 as the second Application Server stack in this example.

The OPC of this stack is 0-0-8 and the stack is configured as an Application Server.

 

  1. Right Click on SS7 Application Server Stack 1 created above and select New Remote Signaling Gateway (SG). The Remote Signaling Gateway is the same Gateway as configured above except the Routing Context is 16.

  1. Right Click on the Remote SG object and select New Sigtran Link. Configure the St-link pane as described above. Note that since this link is connected to the same Remote Signaling Gateway as described above. Note that the Source and Destination Ports needed to be different. See screen capture below. See

  1. Right Click on the Signaling Gateway Stack being configured and select New DPC Route. Information such as Route ID, Destination Point Code, and Remote SG need to be configured in this pane. See ClientView Pane below.

 

sc_m3ua_dpc_route_configure2.png

 

Note: the M3UA DPC is the Point Code of the first Application server stack. Also the Remote Signaling Gateway was chosen from a drop down list of all Remote Signaling Gateways configured.

 

  1. The two Application Server stacks have been created and are communicating with the remote Signaling Gateway. Verify all the links are Active by viewing the Status bar which is the yellow bar at the bottom of the St-link ClientView Panes.

 

 

Configure SS7 ISUP Groups and CICs:

Once the M3UA stacks are configured, the stacks must then be associated with a Channel Group/ISUP Group, and Bearer Span /Channel. Follow instructions below to accomplish this.

  1. Right Click on Dialogic IMG EMS object and select New Routing Configuration. See Routing Configuration link for more information.

  2. Right Click on Routing Configuration just created and select New Channel Groups. See Channel Groups link for more information.

  3. 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.

  4. Right Click on the Channel Group just created and select New ISUP Group. In the OPC-DPC field will be a drop down menu with the two Application Servers created above. Select Application Server Stack 0 (OPC=0-0-7). See screen capture below.

  1. Right Click on the ISUP Group and select New Circuits. Select the Spans/Channels to be used. See Circuit Group for more information

  2. Create a second Channel Group, ISUP Group, and Circuits Pane. The ISUP Group will have the OPC-DPC field of the second Application Server stack (0-0-8) created above and the circuit groups of both Application Server stacks must be physically connected.

  3. Once configured, the CIC's will come In Service. Verify this by viewing the 'Object Table' below the Circuits object pane in ClientView.

  4. Below is a screen capture of the object tree in ClientView. Note that this procedure configures the Application Server Stacks on the same IMG 1010. The Application server stacks can also be created on separate IMG 1010's.
