The user scenario and the steps implemented by the feature to handle this user scenario are as follows:
-
The primary
Communication Manager is inactive and the call processing fails over to the secondary ESS.
CMS detects the TCP/IP link problem to the main Communication Manager system and tries to reconnect.
After five attempts to connect to the primary Communication Manager system,CMS tries the secondary link. When the TCP/IP connection is established, CMS starts receiving call center traffic data.
-
When the primary
Communication Manager system is backed up and ESS releases control of all the resources, the ESS node drops the link.
CMS detects a problem with the TCP/IP link to the Survivable Communication Manager system.
CMS tries the primary link. When the TCP/IP connection is established, CMS starts receiving call center traffic data.
