Term Definition
Routing
The data path through which calls or information are passed. In a
TNPP or TAP system, routing is the sequence in which a page is
passed between paging terminals.
Satellite
An orbiting system in space that receives radio communications from
earth transmitters and resends the information to remote locations.
Security Code
A number required to access some portion of the paging terminal
operation. Different security codes can be enabled to access system
voice prompt programming mode and individual subscribers.
Sensitivity
The minimum input signal strength required to receive a given radio
transmission.
Sequenced
Subscribers
Two or more subscriber records that have either consecutively
numbered capcodes, or phone numbers, or both. A set of sequenced
Subscriber records can easily be created using the S command.
Sidetone
An undesirable audio echo that occurs when the audio hybrids are not
properly balanced. Sidetone is caused when the FROM TEL and TO
TEL connections are not isolated from one another.
Signaling
The exchange of information between functional parts of a communi-
cation system. Telephone signaling generally refers to the type of
trunk (DID, end-to-end, etc.) and the call initiation circuit (loop,
ground, or wink start).
Silence Compression
A feature in the paging terminal that eliminates periods of excessive
silence from voice recordings. Silence compression can be enabled to
shorten custom voice prompts and voice pages in which the speaker
pauses too much between phrases.
Simulcasting
Simultaneous transmission of paging data from several transmitters in
overlapping regions to achieve wide-area coverage. Simulcasting
requires a high degree of accuracy to avoid garbled signals.
Site
The radio equipment at a single location. The site may consist of a
single paging terminal or several terminals with connected equipment.
Sorting
A method of organizing database records so the pertinent data is easily
recognized. For example, it may be useful to sort the Subscriber data-
base by name to locate a specific customer’s record. The Model 640
databases can be sorted by any field using the F (ind) command.
Source
The origination of some type of data. Often the source refers to the
TNPP node from which a page originated. Note that the source node is
not necessarily the paging terminal that sent the page directly to the
Model 640.
SOH (Start of Header)
An ASCII character used in TNPP packets to indicate the beginning of
the packet header data. (The header identifies the packet.) The SOH
character (J) should be included in every valid TNPP packet.
