The Call Server Connector (CSC) snap-in is a Voice-only Service Provider interface to the underlying switching infrastructure. CSC provides call control and agent control functions.
In the Avaya Oceana®, CSC communicates with Communication Manager through the Device, Media and Call Control (DMCC) interface in the Application Enablement Services. The CSC is implemented as a TSAPI application to receive Communication Manager events through Application Enablement Services. CSC uses Application Enablement Services to control and monitor Communication Manager Voice calls and resources.
