See Digital Private-Line. See also PL.
See digital signal processor.
See digital signal processor code.
See Data terminal equipment.
See 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.
Electrically Programmable Digital Potentiometer.
See 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.
Federal Communications Commission.
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 document that provides interim updates to a publication until the
entire publication can be updated and reissued.
Number of times a complete electromagnetic-wave cycle occurs in a
fixed unit of time (usually one second).
