The heartbeat capability allows a client to query the server for the status of a CTI link. Heartbeat is a two-way capability. Communication Manager (as the client) can issue the heartbeat to the AE Server, or the AE Server (as the client) can issue a heartbeat to Communication Manager. Additionally, an AE Services client, such as TSAPI, JTAPI, or CVLAN can initiate a heartbeat to the AE Server.

In the AE Services Management Console you can set heartbeat state to Off or On. If heartbeat is set to off, Communication Manager initiates a heartbeat request. If the heartbeat is set to on, AE Server initiates the heartbeat request.
