This figure shows the Service Broker, SVC, and network components required to configure an SVC implementation.

The Social Voicemail, Social Voice, and Social Circle services each connect to the Service Broker Orchestration Engine (OE) through a separate instance of a Service Broke IM-ASF-SAL interworking module. The Social Circle take/place calls and Click-to-Dial services connect to the OE through one IM-ASF-ASL.

To connect to an IMS telecom network, Service Broker requires the IMS network node connect using a Service Broker SSU SIP. The SSU SIP connects to the OE through an R-IM-ASF (one per network node). To connect to an SS7 network, Service Broker requires the network node connect using the SSU SS7 SIGTRAN. The SSU SS7 SIGTRAN connects to the OE through an IM-ASF (one per network node).

To connect a Diameter online charging engine to Service Broker, you use the SSU DIAMETER, which connects to the OE through IM-OCF. To connect a Diameter offline charging engine to Service Broker, you use the SSU DIAMETER. Offline charging does not us and interworking module; it connects directly to the OE.
