Full Switchover

Last Updated : Mar 24, 2023 |

In a Full Switchover scenario, the DC1 Avaya Aura® components are non-functional, so all the functionality moves to the DC2. The link between the DC2 Application Enablement Services and the Enterprise Survivable Server (ESS) configured under Survivable Hierarchy becomes active because the main switch connection between the DC2 Application Enablement Services and the Communication Manager is not functional. This enables Avaya Oceana® to continue working in the fully switched-over state with voice capability.

  • DC2 Avaya Oceana® is active.

  • The DC2 CallServerConnector snap-in connects to the DC2 Application Enablement Services through Khepri connectors (x2).

  • The DC2 Application Enablement Services connects to the ESS through Computer Telephony Integration (CTI) Link 4.
