'Summary period' IAD Group Statistics


Parameter

Type of statistic

Description
Calls in progress (all types) Gauge Number of calls currently in progress on the IAD Group. This count includes both ADPCM (G.726) and PCM (G.711) calls, and includes any subscriber for which a tone (such as the reorder tone) is being played, regardless of whether the subscriber is actually in a call.
Calls in progress (PCM only) Gauge Number of PCM (G.711) calls currently in progress on the IAD Group. This count includes any PCM subscriber for which a tone (such as the reorder tone) is being played, regardless of whether the subscriber is actually in a call.
Count of failed attempts to allocate bandwidth Counter Number of failed attempts to allocate new bandwidth to a termination because of insufficient IAD Group bandwidth. This type of failure typically occurs
  • during outbound call setup when a subscriber goes off hook
  • during inbound call setup before a ring is applied
  • when adding parties to multi party calls.
This failure is fatal to these operations, and is observable to subscribers. If a failure is counted in the field of the same name in the IAD Statistics object, it is not also counted here.
Count of failures to change media format on existing terminations Counter Number of failed attempts to change the media format in use by an existing termination because of insufficient IAD group bandwidth. This type of failure occurs on active calls, and can result in failure of the call. If a failure is counted in the field of the same name in the IAD Statistics object, it is not also counted here.
