DEFINITION
P25-compliant digital communication system offered by Motorola
Solutions
Bit Error Rate; identifies the quality degradation of a data stream over a
communication channel. Typically altered due to noise, interference,
distortion, or bit synchronization errors.
Base Station Identifier / Call Sign; sent over-the-air, sometimes as
Morse Code, to identify the originating transmitter
Common Air Interface (P25 standards-based RF Signalling)
Conventional Channel Gateway (Conventional Channel Interface to
ASTRO 7.x system)
Continuous Tone-Coded Squelch System (In band signaling controlling
squelch control in analog radio systems), also known as Motorola PL
Digital Coded Squelch (In band signaling controlling squelch control in
analog radio systems), also known as Motorola DPL
Digital Fixed Station Interface – Radio over IP interface protocol as
defined in TIA-102.BAHA-A standard document.
Digital Interface Unit; Provides wireline vocoding and encryption in
ASTRO 3.1 systems
Daylight Saving Time
An electronic device that allows bi-directional (duplex) communication
over a single path. It isolates the receiver from the transmitter while
permitting them to share a common antenna.
Bidirectional simultaneous communications
Fallback In-Cabinet Repeat: A mode of operation when PDR8000
activates a local-repeat function if it's wireline link becomes impaired
Futurecom Repeater Configurator: The application for configuring
PDR8000 (formerly known as Tweaker)
Global Positioning System
A model of Motorola Solutions base/repeater stations
Bidirectional communications utilizing two paths/frequencies, but only
one at a time
Light Emitting Diode
A radio channel carrying both P25 (CAI) and Analog FM radio traffic.
(Usually provided to help support legacy, non-P25 subscriber units that
need to operate at an incident scene where P25 subscriber units are in
use.)
Network Access Code; identifier driving squelch operation on received
Digital channels. Replaces PL/DPL (CTCSS/DCS) functionality from
analog radio systems.
Over The Air Rekeying (method of updating encryption keys in devices
via encrypted over-the-air transport)
