Group Direction. Identifies whether the trunk group is incoming (inc), outgoing (out), or two-way (two).

Group Size. The number of trunks in the trunk group.

Group Member Number. The number that identifies a specific trunk member (in the group) out of service.

Number of Sampled Outages. The number of times the group member is sampled as out of service over the period covered by the report (yesterday, today, or last hour). Yesterday includes the 24 hours beginning at midnight and ending at midnight. Today includes those hours from midnight to the most recently completed hour. Last hour only includes the most recently completed hour. Note: If there are no outages, no data is displayed.

Suggested actions:

• The sampling period is once per hour. Therefore, if the report covers several hours (for example, the yesterday or today report) but the column only indicates a small number of outages, then the trunk member may be providing intermittent service. To determine whether a specific trunk member is functioning, use the Facility Test Calls feature.

• If a trunk is suspected of causinACAg problems, use the feature to monitor the particular trunk group.

• If a trunk member is totally out of service, then (depending on local arrangements) you may choose to refer the problem to maintenance personnel.
