Two IMGs 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 IMGs in the same Logical IMG. The Remote IMGs do not require any SS7 signaling connections or SS7 signaling configuration.

The following illustration shows a scenario where SS7 Redundancy and Remote Control of CICs are both employed.
