Code executed by an embedded processor such as the Host or DSP in
a subscriber radio. This type of code is typically resident in non-volatile
memory and as such is more difficult to change than code executed
from RAM.
See frequency generation unit.
A non-volatile memory device similar to an EEPROM. Flash memory
can be erased and reprogrammed in blocks instead of one byte at a
time.
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.
See Florida Manual Revision.
A publication that provides supplemental information for its parent
publication before it is revised and reissued.
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.
Pins whose function is programmable.
See General-Purpose Input/Output.
Disconnect.
The first information display shown after a radio completes its self test.
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.
