DS0s used for control channels are not included in any of the counts of DS0s in these statistics.
DS0 terminations count as "configured" if the parent DS1 is enabled, the parent IDT interface is enabled, and the parent IDT is activated. All configured DS0 terminations are then categorized as either available, deactivated or failed. If the parent DS1 and IDT interface are both activated, the DS0 terminations count as either available or failed, depending on the hardware state. Otherwise, the DS0 terminations count as deactivated.
All available DS0 terminations are then categorized as in use or not in use. DS0s in use for nailed-up connections are always counted as "in use", regardless of whether they are currently in a call. However, they are only counted as "in use for originating / terminating calls" when they are actually in a call. For the "Call usage - all calls" statistic, each "nailed up" connection is counted as permanently in use (36 Centa Call Seconds per hour).
The following statistics are collected for the Call Agent object.

Description |
Number of active subscribers - number | Gauge | The number of subscribers configured to use this IDT. |
Number of active subscribers - low water mark | Low | The lowest number of subscribers configured to use this IDT at any time during the summary period. |
Number of active subscribers - high water mark | High | The highest number of subscribers configured to use this IDT at any time during the summary period. |
DS0 terminations configured - number | Gauge | The number of DS0 terminations configured on this IDT. A termination counts as configured if the parent DS1 is enabled, the parent IDT interface is enabled, and the parent IDT is activated. |
DS0 terminations configured - low water mark | Low | The lowest number of DS0 terminations configured on this IDT at any time during the summary period. |
DS0 terminations configured - high water mark | High | The highest number of DS0 terminations configured on this IDT at any time during the summary period. |
DS0 terminations available - number | Gauge | The number of DS0 terminations available for use on this IDT. This counts all configured DS0 terminations that are not deactivated or failed. In particular it includes terminations that are currently in use for calls or are assigned to nailed-up connections, as well as those that are not in use but could be used. |
DS0 terminations available - low water mark | Low | The lowest number of DS0 terminations available for use on this IDT at any time during the summary period. |
DS0 terminations available - high water mark | High | The highest number of DS0 terminations available for use on this IDT at any time during the summary period. |
DS0 terminations in use - number | Gauge | The number of DS0 terminations on this IDT in use during the summary period. This includes terminations that are in use for "nailed up" connections, regardless of whether they are currently in a call. |
DS0 terminations in use - low water mark | Low | The lowest number of DS0 terminations in use on this IDT at any time during the summary period. |
DS0 terminations in use - high water mark | High | The highest number of DS0 terminations in use on this IDT at any time during the summary period. |
DS0 terminations in use for originating calls - number | Gauge | The number of DS0 terminations in use for originating calls on this IDT during the summary period. This includes terminations that are in use for "nailed up" connections only if they are currently in an originating call. |
DS0 terminations in use for originating calls - low water mark | Low | The lowest number of DS0 terminations in use for originating calls on this IDT at any time during the summary period. |
DS0 terminations in use for originating calls - high water mark | High | The highest number of DS0 terminations in use for originating calls on this IDT at any time during the summary period. |
DS0 terminations in use for terminating calls - number | Gauge | The number of DS0 terminations in use for terminating calls on this IDT during the summary period. This includes terminations that are in use for "nailed up" connections only if they are currently in a terminating call. |
DS0 terminations in use for terminating calls - low water mark | Low | The lowest number of DS0 terminations in use for terminating calls on this IDT at any time during the summary period. |
DS0 terminations in use for terminating calls - high water mark | High | The highest number of DS0 terminations in use for terminating calls on this IDT at any time during the summary period. |
DS0 terminations deactivated - number | Gauge | The number of deactivated DS0 terminations on this IDT during the summary period. A termination counts as deactivated if the parent DS1 and IDT are not both activated. |
DS0 terminations deactivated - low water mark | Low | The lowest number of deactivated DS0 terminations on this IDT at any time during the summary period. |
DS0 terminations deactivated - high water mark | High | The highest number of deactivated DS0 terminations on this IDT at any time during the summary period. |
DS0 terminations failed - number | Gauge | The number of failed DS0 terminations on this IDT during the summary period. |
DS0 terminations failed - low water mark | Low | The lowest number of failed DS0 terminations on this IDT at any time during the summary period. |
DS0 terminations failed - high water mark | High | The highest number of failed DS0 terminations on this IDT at any time during the summary period. |
Call attempts - count of originating call attempts | Counter | Number of originating call attempts using this IDT during the summary period. |
Call attempts - count of terminating call attempts | Counter | Number of terminating call attempts using this IDT during the summary period. |
Call attempts - count of failed call attempts (congestion) | Counter | Number of call attempts using this IDT during the summary period that failed because of congestion. |
Call usage - all calls | Usage | Total call usage on this IDT, in CCS (Centa Call Seconds). 1 CCS = 100 seconds of total call time. This statistic counts each "nailed up" connection as being permanently in use (36 CCS per hour). |
Call usage - originating calls | Usage | Call usage for originating calls on this IDT, in CCS (Centa Call Seconds). 1 CCS = 100 seconds of total call time. |
Call usage - terminating calls | Usage | Call usage for terminating calls on this IDT, in CCS (Centa Call Seconds). 1 CCS = 100 seconds of total call time. |
Failures - calls failed due to hardware failure | Counter | Number of times a call failed because of a problem with the NE hardware. |
Failures - calls failed due to unexpected DLC disconnection | Counter | Number of times a call failed because the DLC unexpectedly terminated the connection. |
Failures - control channel failures | Counter | Number of times a control channel failed. |
