A 13-digit code which uniquely identifies the System Software Package
and Software Revenue Options that are enabled in a particular
subscriber radio. FLASHcodes are only applicable for radios which are
upgradeable through the FLASHport process.
A Motorola term that describes the ability of a radio to change memory.
Every FLASHport radio contains a FLASHport EEPROM memory chip
that can be software written and rewritten to, again and again.
Number of times a complete electromagnetic-wave cycle occurs in a
fixed unit of time (usually one second).
This unit generates ultra-stable, low phase noise master clock and other
derived synchronization clocks that are distributed throughout the
communication network.
Field Programmable Gate Array.
Global Core Accessory Interface. Used to connect accessories and
programming cables to the control head and the TIB.
Pins whose function is programmable.
See General-Purpose Input/Output.
Object code executed by the host processor in an ASTRO subscriber
radio. The host is responsible for control-oriented tasks such as
decoding and responding to user inputs.
See integrated circuit.
Intermediate Frequency.
A sub-band, voice-encoding algorithm used in ASTRO digital voice.
Data transmitted on the control channel from a subscriber unit to the
central control unit.
An assembly of interconnected components on a small semiconductor
chip, usually made of silicon. One chip can contain millions of
microscopic components and perform many functions.
See inbound signaling word.
A device used to load encryption keys into a radio.
See kilohertz.
One thousand cycles per second. Used especially as a radio-frequency
unit.
See key-variable loader.
