Keywords:
The report contains two sections: a header section that provides report ending time and trunk group administrative information; and a data section that provides the measurement data for 24 hours.
Note:
If a translation change has occurred during a particular hour, the system displays an asterisk (*) in front the data for the hour in which the translation change occurred.
Name
Description
Grp No
Group Number. A number that identifies the trunk group associated with the displayed data.
Grp Size
Group Size. The number of trunks in the trunk group.
Grp Type
Group Type. All trunk group types except PCOL trunk groups.
Grp Dir
Group Direction. Incoming, outgoing, or two-way.
Que Size
Queue Size. The size of the trunk group queue. If there is no queue, the size is zero and the other queue measurements are irrelevant.
Name
Description
Meas Hour
Measurement Hour. The starting time (using 24-hour clock) of the hour during which the data is recorded.
Total Usage
The usage that wideband calls contribute to this measurement is proportional to the resources the calls consume. For example, a 384-kbps call contributes six times more to the total usage than does a 64-kbps call.
The total time (in CCS) trunks in the trunk group are unavailable to carry a new call. It includes the time the trunks are busy on calls, false starts, don’t answers, or any other reason the trunk is unavailable. Not included are calls denied service on the trunk group for authorization reasons or because of queue overflow.
Maint Usage
Maintenance Usage. The total usage (in CCS) of trunks in this trunk group for Maintenance Busy or any other non-call situation where trunks are not available to carry a call.
Total Seize
Total Seizures. The total number of seizures on the trunk group.
Inc. Seize
Incoming Seizures. The number of incoming seizures on the trunk group.
Tandem Seize
Tandem Seizures. The number of trunk-to-trunk call seizures. This count is incremented on the outgoing-trunk side of the connection.
Grp Ovfl
Group Overflow. The outgoing calls offered to the trunk not carried. These are calls that arrive when all trunks in the group are busy and are not queued on the trunk group. It does not include calls denied service on the trunk group because of authorization reasons.
Call Qued
Calls Queued. The calls that enter the trunk group queue. This can happen automatically for analog terminal users or at the request of the caller for other terminal types.
Que Ovf
Queue Overflow. The number of calls that arrive when all slots in the Trunk Group Queue are occupied.
Que Abd
Queue Abandoned. Calls removed from the queue either by the system because they have been in the queue for the maximum allowed time (currently fixed at thirty minutes), or forced by users when they cancel the auto-call back, set earlier to put the call in the queue.
Out Serv
Out of Service. The number of trunks in the trunk group out of service at the time the data is collected.
% ATB
Percent All Trunks Busy. The percentage of time during the measurement interval all trunks in the group are unavailable to carry a new call (All Trunks Busy).
%Out Blk
Percent Outgoing Blocking. The percent of the outgoing seizures, including tandem seizures, offered to that trunk group that are not carried on that trunk group. The value is calculated as follows:
% Out Blk = {Grp Ovfl / [Total Seize - Inc Seize> x 100
Wideband Flag
If the trunk group supports wideband (n X DS0) switching, the system displays Wideband Support in the report heading.
