This diagram shows the configuration components used to connect VPN services to the SS7 and IMS networks. It consists of a boxed labeled VPN Feature at the top, which connects to the IM-ASF-SAL, which in turn connects to the orchestration engine. The orchestration engine connects to the IMS Network cloud through R-IM-ASF SIP and IM-ASF SIP interworking modules. It connects to the SS7 Network cloud through the IM-SCF CAP4 interworking module.
