Glossary
codeplug
Firmware that contains the unique personality for a system or device. A
codeplug is programmable and allows changes to system and unit
parameters.
See also firmware.
coder/decoder
A device that encodes or decodes a signal.
CPS
See Customer Programming Software.
Customer
Programming
Software
Software with a graphical user interface containing the feature set of an
ASTRO radio.
D/A
See digital-to-analog conversion.
DAC
See digital-to-analog converter.
Data terminal
equipment
Data terminal equipment; for example, a computer.
default
A pre-defined set of parameters.
digital
Refers to data that is stored or transmitted as a sequence of discrete
symbols from a finite set; most commonly this means binary data
represented using electronic or electromagnetic signals.
See also
analog.
digital-to-analog
conversion
Conversion of a digital signal to a voltage that is proportional to the input
value.
See also A/D.
digital-to-analog
converter
A device that converts digital data into analog signals.
See also ADC.
Digital Private-Line
A type of digital communication that utilizes privacy call, as well as
memory channel and busy channel lock-out to enhance communication
efficiency.
digital signal
processor
A microcontroller specifically designed for performing the mathematics
involved in manipulating analog information, such as sound, that has
been converted into a digital form. DSP also implies the use of a data
compression technique.
digital signal
processor code
Object code executed by the Digital Signal Processor in an ASTRO
subscriber radio. The DSP is responsible for computation-intensive
tasks, such as decoding ASTRO signaling.
DPL
See Digital Private-Line. See also PL.
DSP
See digital signal processor.
DSP code
See digital signal processor code.
DTE
See Data terminal equipment.
EEPOT
Electrically Programmable Digital Potentiometer.
