codeplug
Firmware that contains the unique personality for a system or device. A
codeplug is programmable and allows changes to system and unit
parameters.
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 communication
equipment
Definition for device (such as radio) data communications using the
RS232 protocol. The correct data communication wiring requires the
device’s TX pins (output) to connect to the RX pins (input) and the RTS
pins (output) to connect to the CTS pins (input). It is incorrect to attach
device pins having the same name to to each other.
Data terminal
equipment
Data terminal equipment; for example, a computer.
DCE
See Data communication equipment.
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.
digital-to-analog
conversion
Conversion of a digital signal to a voltage that is proportional to the input
value.
digital-to-analog
converter
A device that converts digital data into analog signals.
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.
