Manufacturer’s ID (MFID)
The Header Code Word and Link Control Word (LDU1) contain the 8 bit MFID fi eld. When the
manufacturer uses non-standard (data only) features, the MFID is asserted. When all of the other
information fi elds conform to the Common Air Interface defi nitions, the MFID has a standard value of
$00 or $01. A P25 radio must, as a minimum, transmit or receive messages using the the standard
values for the MFID fi eld. As a minimum, a P25 receiver will ignore messages which do not contain
the standard values for the MFID fi eld. Every manufacturer is assigned an MFID that can be used
for proprietary signaling. Non-standard data from one manufacturer may not pass through another
manufacturers repeater system.
