Statistics and System Resource Management

172 025-9034AA

A configuration file on the terminal is used to establish your trunk Groups (which trunk

lines are grouped together for Statistics purposes). Refer to .CUS Files in Series 2000

Paging Terminals Installation and Maintenance for details.

The Statistics accumulated are the Average and the Maximum. In addition, if the Print

Stats is done, a third statistic is listed showing the number of times the Maximum value

was reached.

The Average is the average usage of the resource during the hour. For instance, suppose

you have a group of four trunks, and the average during a particular hour is one trunk. This

means that, on average, one of the four trunks was in use at any given time. In other words,

if you sat in front of the paging terminal and watched the front of the trunk cards, you

would see that, averaged over an hour, one trunk was usually in use. This might mean that

at one moment, no trunks were active; a minute later, three might be in use all at once. The

Average only tells you the overall average.

Fractional averages are normal. In a group with just one trunk in it, you might get an

average of 0.25. This means that on average, one quarter of a trunk was in use. In other

words, the single trunk line was in use one quarter of the time (on average) during the

hour.

The Maximum is the peak value reached at any time during the hour. In a group of four

trunks, if at most three calls were in progress simultaneously at any one time during the

hour, the Maximum would be three for that hour.

The nMaximum is an additional statistic available when you Print statistics instead of

looking at the histograms. This statistic tells you how many times the Maximum value was

reached. This makes the Maximum statistic more useful: it makes a big difference if the

Maximum of four trunks in use in a group of four was reached for a few seconds during an

hour, or for most of the hour.

Table 23 lists the details on these statistics.

The Y-axis of each histogram (Number of Trunks, Page Delay Time, or Seconds Waiting

for Voice Channel) is automatically scaled to cover the range used by your system.
