CentreVu® CMS R3V8 Database Items and Calculations

1

The G3V4 and later switches calculate a roilling average speed of 
answer (ASA) for splits/skills and VDN(s). This ASA can be used in 
vector conditionals to determine where to queue calls. The ASA(s) for 
splits/skills and for VDN(s) are also sent to R3V4 and later CMS, and can 
be displayed on real-time reports.

The ASA for a split/skill includes the time spent in the split/skill queue and 
the time ringing at an agent. The ASA for a VDN includes the time spent 
in vector processing (including the time spent in queue) and the time 
ringing for the VDN assocaited with the call when it was answered. This 
switch-generated, rolling ASA is a running, weighted average calculation. 
ASA will in general not match the average speed of answer on CMS.

The times ACW feature, which provides automatic-in agents with a fixed 
ACW period after each Automatic-In call, makes no changes in CMS 
tracking of ACW time. Timed ACW is tracked identically to manually 
entered ACW or ACW resulting from manaul-in calls.

1

In the trunk, trunk group, and VDN tables, the TIME items typically 
accumulate until the trunk drops at the end of the call, unless the items 
are queue time or ring time or other similar items. 

1

In the split/skill and vector tables, the TIME items typically accumulate 
until the call leaves the split/skill/vector and the disposition is known (for 
example, when the call outflows or when the caller starts hearing the 
forced busy).

1

This timer starts when the switch first seizes the trunk and is stopped 
when answer supervision is sent for the call. If it times out, the call is 
dropped by the switch and the 

CentreVu CMS counts the call as an 

abandoned call. (This timer is for switches in countries that lack 
disconnect supervision for trunks. The assumption is that the caller 
abandoned long ago.)
