DTMF
See dual tone multi-frequency.
dual tone multi-
frequency
The system used by touch-tone telephones. DTMF assigns a specific
frequency, or tone, to each key so that it can easily be identified by a
microprocessor.
EEPROM
See Electrically Erasable Programmable Read-Only Memory.
effective radiated
power
The power supplied to an antenna multiplied by the antenna gain in a
given direction. ERP is usually calculated by multiplying the measured
transmitter output power by the specified antenna system gain, relative
to a half-wave dipole, in the direction of interest.
EIA
Electronic Industries Association
Electrically Erasable
Programmable
Read-Only Memory
A special type of PROM that can be erased by exposing it to an
electrical charge. An EEPROM retains its contents even when the
power is turned off.
electronic
potentiometer
A digital potentiometer that is electrically programmable.
EPOT
ERP
See effective radiated power.
FCC
Federal Communications Commission.
firmware
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.
FGU
See frequency generation unit.
flash
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.
FLASHcode
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.
FLASHport
A Motorola term that describes the ability of a radio to change memory.
Every FLASHport radio contains a FLASHport memory chip that can be
software written and rewritten to, again and again.
FMR
See Florida Manual Revision.
Florida Manual
Revision
A publication that provides supplemental information for its parent
publication before it is revised and reissued.
