MTSX RSS
Disk Drive The device that reads and programs information on a permanent storage medium; that is,
floppy or hard disks.
Diskette An alterable permanent magnetic storage medium for microcomputers. Also called a disk,
floppy disk or mini diskette.
DOS Data Operated Squelch. When enabled, DOS will detect an incoming packet of the same
signalling scheme as the radio, and squelch the audio for the duration of the packet. A small
blip of data will be heard,but most of the packet will not be heard.DPL
Line coded squelch. A channel that has DPL on the receive frequency will require both the
presence of carrier as well as the correct DPL code before it will unmute. Also, if you have
DPL on the transmit frequency, all transmissions on that channel will be modulated at a sub-
audible level by the DPL code. Modulation is continuous.
DPL Digital Private Line A continuous sub-audible data signal that is transmitted along with a
carrier. A radio that has DPL on the receive frequency will require both the presence of
carrier and and the correct DPL code before it will unmute. Also, if there is DPL on the
transmit frequency, the DPL code during transmissions made on that channel will be
continuous.
DTMF An acronym for Dual Tone Multi-Frequency. DTMF is a signalling system used by the
telephone system
EEPROM Electronically Erasable Read-Only Memory. Used by the radio to store its alterable
personality data.
Enter A synonym for the carriage return key.
Error Any condition that prevents the software from functioning properly or any input/response that
deviates from what the software was designed to accept.
ESC The escape key pressing this key returns you to the main menu.
Exit To leave the current screen and return to the previous screen. The RSS uses the F10
function key for all exit operations.
Failsoft In the event the Central Controller should fail, the radios in the system will enter a
'conventional" preassigned failsoft channel. Each trunked repeater in the system will key
and transmit a data word informing every radio that the system has gone into the failsoft
mode and communication will act as a conventional radio repeater.
Field The changeable area located next to a feature on the screen. The current selected field is
always highlighted via inverse video.
File A collection of information typically stored by the computer on a magnetic medium.
Fleet A grouping structure used in Type I trunking. A fleet is a group of radio users with a common
functional responsibility who, under normal circumstances, coordinate actions among
themselves.
Fleet Mapping In the process of identifying who needs to talk to whom and how individual radio users
should be grouped. The fleet map also addresses expansion needs; how many radios may
be added to the system.
Floppy Disk Drive A disk drive that uses removable magnetic disks.
Frequency The location of the center of a channel in the radio spectrum (measured in MHz).
