Term Definition
Static
Interfering noise picked up by a receiver. Static is often caused by
lightning or conflicting man-made electrical products.
Station
See Radio Station .
Statistics
A mathematical analysis of data. The Model 640 offers statistics on
many characteristics of the paging system. For example, a statistics
file is available that shows the average and maximum number of
pages transmitted per minute. Statistics can be viewed using either
ZLINK or MCU. Statistics help the system operator manage the
paging terminal more efficiently, identify the need for more resources,
and troubleshoot throughput problems.
STX (Start of text)
An ASCII character used in TNPP packets to indicate the beginning of
the message data. The STX character (
J ) should be included in every
valid TNPP packet.
Subscriber
A paging customer. In the Model 640 databases, a subscriber is a
record that identifies the customer’s name, phone number, pager
capcode, security code, status, call count, and class of service.
Supervision
When a switching network monitors the status of a telephone line for
the duration of a call.
Switch
A telecommunication device that connects multiple line inputs and
outputs. The switch controls the routing and organization of the data
transmission paths.
System Configuration
Files
Several customized files stored in the Model 640 that define the oper-
ating characteristics of the paging terminal. System configuration files
are factory programmed and are usually only modified by qualified
Zetron personnel.
Talkback Paging
A feature in the Model 640 that allows a subscriber with a mobile
radio to be connected with a caller for 2-way communication. When
the paging terminal receives a talkback call, the subscriber is paged to
alert them of a waiting caller. When the subscriber calls into the
paging terminal, they are automatically connected to the calling party.
Telco
A local telephone service provider. The telco leases line types and
services to customers.
TAP (Telocator
Alphanumeric Paging)
Protocol
A standardized alphanumeric paging format that enables paging
encoders to pass pages between remote sites. TAP networking is
similar to TNPP, but the format is less rigid, allowing for a greater
variety of paging types and data.
TNPP (Telocator
Network Paging
Protocol)
The most popular format for wide-area paging networks. TNPP
supports both capcode and ID paging in virtually every format avail-
able. The protocol uses RS-232 data in ASCII character format to send
and receive pages between remote paging encoders.
