BBP See baseband interface port.
baseband interface
port Synchronous serial interface to the transceiver board used to transfer
transmit and receive audio data.
BGA See ball grid array.
ball grid array A type of IC package characterized by solder balls arranged in a grid
that are located on the underside of the package.
CODEC See coder/decoder.
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.
DCE Data communication equipment: The EIA definition for device (i.e.,
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 the “same name” to “same name”.
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 communications 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.
