Configuring Multiple Remote IMG's for SS7

Below is diagram of an SS7 Network. Configured is a Primary and Secondary IMG along with four remote IMG 1004's and IMG 1010's. Click on one of the following links which corresponds to wording in the diagram and a screen capture will appear displaying what the ClientView Pane would look like when configuring a basic SS7 network.

Definitions:

SS7 Redundancy- Two IMG's load-share SS7 signaling links. If the Primary IMG is lost, the Secondary IMG takes over all signaling requirements.

Remote Control of CICs- One IMG is an SS7 Server Node and handles all SS7 signaling for other IMG's in the same Logical IMG Group. The Remote IMG's do not require any SS7 signaling connections or SS7 signaling configuration.

SS7 Redundancy with Remote Control of CICs- Two IMG's load-share SS7 signaling links. If the Primary IMG is lost, the Secondary IMG takes over all signaling requirements. The Primary IMG is also an SS7 Server Node and handles all SS7 signaling for other IMG's in the same Logical IMG Group. The Remote IMG's do not require any SS7 signaling connections or SS7 signaling configuration.

Steps

• In ClientView, configure the Primary SS7 server IMG0_1010 and make IMG1_1010 the Secondary.
  
  

• Configure Stack 0 on Primary SS7 with OPC = 1-1-1.
  
  

• Configure the Link Set under Stack 0.
  
  

• Configure SS7 Link 0 which is connected from Primary SS7 server to SS7 network.
  
  

• Create Route for Link 0 going to APC 2-2-2.
  
  

• Configure the Link Set under Stack 0
  
  

• Configure SS7 Link 1 which is connected from Secondary SS7 server to SS7 network.
  
  

• Create Route for Link 1 going to APC 3-3-3.
  
  

• Configure the Link Set under Stack 0.
  
  

• Configure SS7 Link 2 which is connected from Rem_IMG2 on IMG 1004 to SS7 network.
  
  

• Create Route for Link 2 going to APC 4-4-4.
  
  

• Configure the Link Set under Stack 0. 
  
  

• Configure SS7 Link 3 which is connected from Rem_IMG3 on IMG 1010 to SS7 network. 
  
  

• Create Route for Link 3 going to APC 5-5-5. 
  
  

Once all Stacks ,Link Sets, Links, and Routes are configured, the CIC's can be created. The CIC's are created under the channel group object. See Channel Group topic on information on how to create a channel group. Follow procedure below to create the cics and associate them with a specific IMG.

• Create an SS7 Channel Group

• Under Channel Group 0 object right click and select New ISUP group. In the OPC-DPC field select from drop down menu which Stack/Route to be used. 
  
  

• Under the ISUP Group create CICs and associate them with a specific IMG.
  
  

• Create an second SS7 Channel Group

• Under Channel Group 1 object create an ISUP group which contains CIC's for Secondary IMG1.
  
  

• Under the ISUP Group create CICs and associate them with a specific IMG. 
  
  

• Create a third SS7 Channel Group

• Under Channel Group 2 object create an ISUP group which contains CIC's for Remote IMG2. 
  
  

• Under the ISUP Group create CICs and associate them with a specific IMG. 
  
  

• Create a fourth SS7 Channel Group

• Under Channel Group 3 object create an ISUP group which contains CIC's for Remote IMG3.
  
  

• Under the ISUP Group create CICs and associate them with a specific IMG.
  
  

All Channel Groups are created. Each Channel Group is routed to a different point in the SS7 network. It could be an STP, SDP, etc. The above example is a basic SS7 network to give the user an understanding of how to configure SS7 Stacks, CIC's, Channel Groups etc.
