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 talk group status bits as different talk groups entirely. Below is the conversion chart for these special status bits.

TT ID + # Usage	TT ID + # Usage
ID+0 Normal Talk group	ID+8 DES/DVP Encryption talk group
ID+1 All Talk group	ID+9 DES All Talk group
ID+2 Emergency	ID+10 DES Emergency
ID+3 Talk group patch to another	ID+11 DES Talk group patch
ID+4 Emergency Patch	ID+12 DES Emergency Patch
ID+5 Emergency multi-group	ID+13 DES Emergency multi-group
ID+6 unassigned	ID+14 unassigned
ID+7 Multi-select (initiated by dispatcher)	ID+15 Multi-select DES TG

Therefore, if a user was transmitting a multi-select call on talk group 1808, the scanner would actually receive those transmissions on 1815.

Some common uses of these status bits are as follows:

When a user hits their emergency button, all conversations on the talk group revert to the emergency status talk group (ID+2) until the dispatch clears the emergency status.
