ClientView Tree

The following graphic shows the tree of ClientView panes used for configuring SS7 CIC's.

Open

Configuring an SS7 Channel Group

• Right-click Routing Configuration and select New Channel Groups.

• Right-click Channel Groups and select New Channel Group. The Channel Group pane appears.
  
  

  Open

  

• In the Name field, enter a name for the channel group.

• The ID field is automatically populated with the next available ID. You can change it if you want.

• In the Channel Group Function field, select Incoming Trunks, Outgoing Trunks or Incoming/Outgoing Trunks

• In the Signaling Type field, select SS7.

• Select other fields as required. See the Channel Group GUI Reference for a description of each field.

Do not select a Route Table in the Route Table field at this point. After you configure Route Tables, (see Creating Routing Tables) you come back to the Channel Group pane and associate a Route Table with the channel group.

Configuring an ISUP Group

• To add ISUP groups to the SS7 Channel Group, right-click the SS7 Channel Group you created and select New ISUP Group. The ISUP Group pane appears.
  
  

• Ensure that the OPC-DPC that defaults in is correct. These values come from the Stack ID and the associated SS7 Route. You associate the stack with the ISUP Group here.

• Select entries in all fields as required. See the ISUP Group GUI Reference for a description of each field.

Configuring FCI Override

Forward Call Indicators contain information relating to the characteristics of the connection, signaling path and called party sent in the forward direction. This is a mandatory parameter in IAM messages, which is used in countries that offer CUG (closed user group) service. To configure the IMG to override various Forward Call Indicators parameters with specified values:

• Right-click the SS7 ISUP Group entry and select New FCI Override. The FCI Override pane appears.

• Enable FCI Override by selecting Override in the FCI Override field.

• Select the desired override value for each parameter.

See IMG 1010 - FCI Override for details.

Configuring TMR-USI Override

To set Transmission Medium Requirements (TMR) and User Service Indicator (USI) parameters:

• Right-click the SS7 ISUP Group entry and select NewTMR_USI Override. The TMR-USI Override pane appears.

• Make selections in each field as required.

See IMG 1010 - TMR-USI Override for details.

Configuring Location Override

• Right-click the SS7 ISUP Group entry and select New Location Override. The Location Override pane appears.

• In the Location Override field, select Override.

• If required, change defaults in the Location and Coding Standard fields

See IMG 1010 - Location Override for details.  

Assigning SS7 Circuits to an ISUP Group ( CICs)

• Right-click the ISUP Group you created and select New Circuits. The Circuit pane appears.
  
  

• In the IMG Name field, select the physical IMG.

• In the IMG Interface field, select Bearer or Signaling.

• In the Start Interface Offset field, enter a value from 0-27 to define where the CICs are going out of the IMG. Make sure this value matches the Interface ID defined for the physical spans. That is, make sure bearer CICs go out over bearer spans and signaling CICs go out over signaling spans.

• In the Trunk Type field, select T1 or E1. Make sure this matches what you defined for physical spans).

• In the Start Channel field, select the first channel where the CICs will get assigned.

• In the Start CIC field, enter the first CIC in the group.

• In the CIC Count field, enter the total number of CICs in the group.

See IMG 1010 - Circuit Group for a description of each field.

Configuring SS7 Parameter Filters

This pane indicates which SS7 parameters are passed on to the outbound side and which are not.  By default, all parameters are passed except for Transit Network Select.

• Right-click the ISUP Group that you created and select New SS7 Parameter Filter. The SS7 Parameter Filter pane appears.
  
  

• If you want to change the default for any of the parameters, select the desired setting from its drop-down list.
