DMA Operations Guide Active Calls

	Table 5-2	Call Details dialog box (continued)
	Tab/Field/Column		Description
	Bandwidth		The table at the top lists each throttle point that the call
			traverses and shows its:
			• Bit rate limit per call (kbps)
			•	Total capacity (kbps)
			• Used bit rate (kbps) in each class of service
			•	Weight (%)
			•	Territory
			If the throttle point is a subnet, site, or site link, a link
			takes you to the corresponding site topology page with
			the throttle point entity selected.
			Below the table, the data used in bandwidth processing
			is displayed (all bit rates are kbps):
			• Formal maximum bit rate limit — the maximum
				allowed bit rate considering the per call bit rates of
				each throttle point, but not considering total capacity
				or current usage
			• Available bit rate capacity in each class of service
				and for the call’s class
			• Class of service for the call
			• Minimum downspeed bit rate
			• Available bit rate limit (%) — the maximum
				percentage of remaining bandwidth at a throttle
				point that will be given to any one call (configurable
				on the Call Server Settings page)
			•	Requested bit rate
			•	Final bit rate
	Call Events		Lists each event in the call and its attributes.
			When the system is operating as a SIP proxy server, the
			list includes all SIP signaling messages except 100
			TRYING.
			Hover over an attribute label to see a description. Click
			Show Message to see the signaling message. Click
			Show QoS Data to see detailed quality of service
			statistics.
	Property Changes		Lists each property change in the call, showing the
			value, time, and sequence number of the associated
			event.
	QoS		Quality of service data is only available if one of the
			endpoints is a registered H.323 endpoint that supports
			IRQs. This tab displays a graph showing how QoS
			varied during the call. The horizontal scale and
			frequency of data points (dots on the lines of the graph)
			vary based on the length of the call.
			Hover over a data point to see the value at that point.
