This image shows an Oracle Cloud Infrastructure region with a single availability domain spread across three fault domains. An active-standby pair of Oracle Communications Session Border Controller (SBC), Subscriber-Aware Load Balancer (SLB), and Session Router (SR) along with a distributed Enterprise Operations Monitor (EOM) are deployed across the two of the fault domains. The architecture diagram covers three use cases:

• Peering interconnect
• Access
• Bring Your Own Carrier (BYOC)

Using Cloud Communication Service (CCS), which is a proxy, a secure connection channel between SBC, SR, SLB, and EOM and cloud services such as OSDMC and OCSS, is established.
