pie chart
A graphical representation of a summary report displaying pie slices as line entries (such as hours in a
Time of Day Traffic Report). The size of the slice corresponds to the percent value of the line entry
over the total value — number or usage (depending on the report).
polled site
The MERLIN LEGEND Reporter term for a site that makes its call record data available for polls from
the Central Site in a multi-site network (also called “remote site”). See Central Site and Multi-site
Network.
polling
The MERLIN LEGEND Reporter process of periodically accessing a PSU or another MERLIN
LEGEND Reporter for its call record data.
privacy
A MERLIN LEGEND Reporter feature, whereby called numbers from specific extensions are partially
or entirely hidden from view — either permanently and/or for reports only.
privileges
Permission granted each user to read and/or change data shared by other users in a computer
system.
protocol
A set of conventions or rules that describe how data is organized, transmitted, and received.
PSU
Pollable Storage Unit. A PSU is a small processor dedicated to collecting and storing call records
from a telephone system, then transmitting them upon request. In this context, the MERLIN LEGEND
Reporter issues the request.
Q
queue time
The time that an incoming call spends in a queue, waiting to be transfered to the requested
destination. MERLIN LEGEND Reporter computes queue time as total duration minus talk time.
R
record
The smallest piece of information that a database management system can retrieve from a file.
Records may contain several items of information (fields) — for example, a MERLIN LEGEND
Reporter call record contains the time of a call, its duration, number dialed, etc.
rejected call
A call discarded by MERLIN LEGEND Reporter because either (a) it did not meet the minimum
duration criteria by Call Type or (b) it matched a dialed digit pattern to be discarded by the Dialed Digit
Processing function. Rejected calls print in the Immediate Output log, flagged by an asterisk (*).
