MIB Name: acPMSIPTrunkGroupNoResourcesCallsTable

■

OID: 1.3.6.1.4.1.5003.10.8.2.52.28

■

Source Name: PM_gwTrunkGroupNoResourcesCalls

Indicates the number of calls that could not be established due to unavailable device resources (e.g., no free channels) per Trunk Group.

■

High threshold: acPMSipAttributesTrunkGroupNoResourcesCallsHighThreshold (1.3.6.1.4.1.5003.10.8.1.34.7)

■

Low threshold: acPMSipAttributesTrunkGroupNoResourcesCallsLowThreshold (1.3.6.1.4.1.5003.10.8.1.34.8)

■

MIB Name: acPMSIPTrunkGroupCallDurationTable

■

OID: 1.3.6.1.4.1.5003.10.8.2.52.29

■

Source Name: PM_gwTrunkGroupCallDuration

Indicates the average call duration (in seconds) of calls per trunk group.

■

High threshold: acPMSipAttributesCallDurationHighThreshold (1.3.6.1.4.1.5003.10.8.1.34.1)

■

Low threshold: acPMSipAttributesCallDurationLowThreshold (1.3.6.1.4.1.5003.10.8.1.34.2

■

MIB Name: acPMSIPTrunkGroupUtilizationTable

■

OID: 1.3.6.1.4.1.5003.10.8.2.52.26

■

Source Name: PM_gwTrunkGroupUtilization

Indicates the number of channels currently in use (busy) per trunk group. For example, if the device has 240 channels and the threshold is set to 106, if the number of concurrent busy channels exceeds 106, this threshold alarm is sent. Note that if a trunk is in LOF state, this MIB counts only the channels that are used.

MIB Name: acPMSIPTrunkGroupPercentageUtilizationTable

■

OID: 1.3.6.1.4.1.5003.10.8.2.52.27

■

Source Name: PM_gwTrunkGroupPercentageUtilization

Indicates the percentage (%) of channels currently in use (busy) per trunk group. The device supports configuration of a busy channel threshold per trunk group, which when exceeded, sends an SNMP alarm. For example, if a device has 200 voice channels and the threshold is set to 90%, if the number of concurrent busy channels exceeds 90% (i.e., 180 channels), this threshold alarm is sent.

■

High threshold: acPMSipAttributesTrunkGroupPercentageUtilizationHighThreshold (1.3.6.1.4.1.5003.10.8.1.34.5)

■

Low threshold: acPMSipAttributesTrunkGroupPercentageUtilizationLowThreshold (1.3.6.1.4.1.5003.10.8.1.34.6)

■

MIB Name: acPMSIPTrunkGroupAllTrunksBusyTable

■

OID: 1.3.6.1.4.1.5003.10.8.2.52.25

■

Source Name: PM_gwTrunkGroupAllTrunksBusy

Indicates the duration (in seconds) that all channels of a specific trunk group were concurrently busy, if this scenario occurs. For example, if trunk group #3 has 200 channels and all these were concurrently busy for 60 seconds, then this MIB will display 60 for this trunk group. Note that trunks that are out of service or not configured (set to NONE) are considered "busy" in this calculation.

■

MIB Name: acPMSIPTrunkGroupAllTrunksBusyPercentageTable

■

OID: 1.3.6.1.4.1.5003.10.8.2.52.40

■

Source Name: PM_gwTrunkGroupAllTrunksBusyPercentage

Indicates the percentage (%) of time within a 15-minute polling interval, that all channels in a specific trunk group were busy simultaneously. This measurement is sent only at the end of the interval (beginning of the current interval), so each measurement reflects the previous interval. For example, assume that all trunks of a trunk group were busy for 6 minutes during an interval. The MIB will send a measurement of 40% (i.e., 6 minutes / 15 minutes * 100). In other words, all trunks of the trunk group were simultaneously busy for 40% of the time during this 15-minute interval.

High threshold: acPMSipAttributesTrunkGroupAllTrunksBusyPercentageHighThreshold (1.3.6.1.4.1.5003.10.8.1.34.33)

■

Low threshold: acPMSipAttributesTrunkGroupAllTrunksBusyPercentageLowThreshold (1.3.6.1.4.1.5003.10.8.1.34.34)

■

MIB Name: acPMTrunkUtilizationTable

■

OID: 1.3.6.1.4.1.5003.10.10.2.21

■

Source Name: PM_TrunkUtilization

Indicates the number of busy channels on a specific E1 / T1 trunk. A busy channel is when the Physical DS0 Termination isn't in Null context or OOS.

■

High threshold: acPMTrunkUtilizationAttributesHighThreshold (1.3.6.1.4.1.5003.10.10.1.31.1)

■

Low threshold: acPMTrunkUtilizationAttributesLowThreshold (1.3.6.1.4.1.5003.10.10.1.31.2)
