The Primary Active state describes the solution in regular operation. The DC2 is prepared for a failover, but all the components are active in the DC1.
Figure : 1. Avaya Oceana® DR Voice - Primary Active state
DC1 Avaya Oceana® is active.
The CallServerConnector snap-in connects to the DC1 Application Enablement Services through Khepri connectors (x2).
The DC1 Application Enablement Services connects to the Communication Manager through Computer Telephony Integration (CTI) Link 1.
The Communication Manager has an active CTI Link (4) to the DC2 Application Enablement Services because both components are functional, but this link is not used in this scenario.
