Type II Special Status Bits
Type II Motorola Smartnet systems use these status bits for special transmissions such as
emergency, patches, DES/DVP scrambled transmissions, and multiselects. Motorola trunking
radios directly interpret them for their special functions, thus no difference is noticed by the person
with the radio. The scanner however interprets these special talkgroup status bits as different
talkgroups entirely. Below is the conversion chart for these special status bits.
