How Fleet Maps Work
Blocks
Talk Group IDs can range from 0 to 65,535. To make it easier to handle this many IDs, the system divides the TGID range into 8 equal
blocks :
| Block | Starting ID | Ending ID
|
| Block 0 | 0 | 8191
|
| Block 1 | 8192 | 16383
|
| Block 2 | 16384 | 24575
|
| Block 3 | 24576 | 32767
|
| Block 4 | 32768 | 40959
|
| Block 5 | 40960 | 49151
|
| Block 6 | 49152 | 57343
|
| Block 7 | 57344 | 65535
|
Size Codes
Each block is assigned a
size code based on the way the control channel sends the TGID data. Note that codes 12, 13, and 14 take up more than one block:
| Size Code | Fleet / SubFleet? / ID | Number of Blocks Needed
|
| 0 | (as Type II ID) | 1
|
| 1 | 128 / 4 / 16 | 1
|
| 2 | 16 / 8 / 64 | 1
|
| 3 | 8 / 8 / 128 | 1
|
| 4 | 1 / 16 / 512 | 1
|
| 5 | 64 / 4 / 32 | 1
|
| 6 | 32 / 8 / 32 | 1
|
| 7 | 32 / 4 / 64 | 1
|
| 8 | 16 / 4 / 128 | 1
|
| 9 | 8 / 4 / 256 | 1
|
| 10 | 4 / 8 / 256 | 1
|
| 11 | 2 / 16 / 256 | 1
|
| 12 | 1 / 16 / 1024 | 2
