Statistics and System Resource Management

Managing System Resources

The Statistics histograms and printouts are valuable tools to help you manage your system.

It may not be clear how to use them; the following discussions may be helpful in

managing your paging system.

Trunks (Number of Trunks in Use)

Symptoms of insufficient phone lines would be frequent busy or ringing signals when

people call into the paging system. This is because all lines to the paging terminal are

already in use, so the phone company or PBX will generate the busy or ringing signal to

the caller.

Since there may be several causes for this situation, the Trunks (Number of Trunks in Use

in a Group) statistic helps you see if you may need more phone lines coming into the

paging terminal.

Watch this statistic, especially if you have recently added more phone numbers (but not

phone lines) or more pagers to the system. If you see it hitting the peak number quite often

during the day, or the average is climbing and is (for instance) nearing three in a group of

four trunk lines, you probably need more lines.

This statistic reflects the effects of the average time per call, the number of calls, and the

number of trunks in a group. A group is one or more lines used for the same purpose, for

instance a group of two rollover lines from a PBX, or a set of six DID lines from the phone

company.

An alternative to getting more phone lines, if you are running out, is to change the way

you are using the paging system. If you have any End-to-End (POTS, residential-type)

phone lines in your system, they tend to take extra time for each call because of no

positive hardware disconnect. Changing to DID, Ground Start, or E&M lines instead

would address this problem.

Other alternatives include reducing the use of voice prompts, both system voice prompts

and client custom prompts; and reducing the use of PageSaver. For example, if you

currently give these features away to all callers, you might start charging something for

them (if possible in your market and situation), to reduce the number of customers to those

who really need the features, thus reducing your average time per call.

You may also simply reduce the voice time per call on voice pagers, for instance if

everyone has 30 second voice time now, 10 or 15 seconds is typically all that is needed

and used on a voice page, so you could reduce trunk time usage that way.

If you have determined you need more trunks to handle your traffic, consider that you will

probably need several things: more trunk card(s) from Zetron, more trunk lines (and

perhaps more DID phone blocks) from your phone company or PBX supplier, and

possibly more voice channels (see below). When the new trunks and lines are installed, be
