Section 470 - TSAPI Programmer’s Guide
DBS-92-470 Issued April 2000 55
Description:
A single DBS CSTA Event Report is sent to a
cstaMonitorDevice
monitor request only.
• Event is sent from the switch to the application.
• Point of view is from a monitor request.
• “No Event” indicates that there is no event report for the situation.
Description:
Reflects the CSTA Local Connection State of the described object after the CSTA Event
Report. Only one connection’s Local Connection State is reflected in the following
diagrams (this state is not related to the local connection state parameter in a CSTA Event
Report). Note the following conventions:
• Before a call is established
During inbound calls, the Local Connection State reflects the Local Connection State
of the device that
actually receives the call
. The state is therefore Null until the device
is alerted. During call setup, if the call is passing through an ACD device, the Local
Connection State does not represent the ACD device’s Local Connection State.
During outbound calls, the Local Connection State reflects the Local Connection
State of the
calling device
.
•
After a call is establis
hed
“This”, “other”, or “last” is used to indicate the party that is being described.
• No Change
“No Change” is used when the event report does not indicate a Local Connection
State change of the monitored device. It may, however, indicate a state change of
another device on the call. A state change of one device on a call generates event
reports for every device on the call that has a monitor request.
