Configuring SS7 CIC routing involves the following tasks:
Configure TMR-USI Override (if required)

Configure Location Override (if required)
The following graphic shows the tree of ClientView panes used for configuring SS7 CIC's.
Right-click Routing Configuration and select New Channel Groups.

Forward Call Indicators contain information relating to the characteristics of the connection, signaling path and called party sent in the forward direction.
