UBCD3600XLT Entering IDs, Fleet Maps & Status Bits

Summary: Reference for entering trunked IDs on each system type, partial IDs, and how Motorola status bits change the talkgroup numbers you see.

Accepted ID Formats

Partial IDs let you receive every ID in a fleet, sub-fleet, agency or block. Partial IDs can also be avoided. Press ./no twice to enter a hyphen; press it once for an “i” (I-Call).

• Motorola Type I – BFF-SS (normal ID: block, fleet, sub-fleet); BFFF-S for fleets 100-127; BFF- (partial fleet); BFFF- (partial fleet, fleets 100-127); B- (partial block); NNNNN for size code 0; iNNNNN for an I-Call with size code 0.
• Motorola Type II – decimal NNNNN or iNNNNN; hexadecimal HHHH or iHHHH.
• P25 – decimal NNNNN or iNNNNNNNN; hexadecimal HHHH or iHHHHHH.
• EDACS – only AFS format can be used for direct entry (except I-Call): AA-FFS (normal); AA-FF- (partial fleet); AA- (partial agency). Decimal NNNN or iNNNNN.
• LTR – A-RR-UUU (area, home repeater, user); A-RR (partial repeater ID). A-RR can’t be used with decimal formats. To enter one, type the area code (0 or 1), press ./no twice for a hyphen, the home repeater number (01-20), press ./no once, then the user ID (1-254).
• I-Call – press ./no once, then enter the ID. For a wildcard I-Call, press ./no once, enter 0.
• Hex IDs – enter them using the same character-selection method as Data Naming.

For a Motorola Type I ID: enter the block and fleet, press ./no twice for a hyphen, then the sub-fleet. For an EDACS AFS ID: agency, ./no twice, then fleet and sub-fleet.

Motorola Fleet Maps

A Type I or II/I system needs a fleet map before the scanner can decode talkgroups properly. The scanner divides IDs into 8 blocks (0-7) and you give each block a size code from 0 to 14. Codes 12, 13 and 14 cover more than one block, so they can only be used in particular blocks: 12 only in blocks 0, 2, 4 or 6; 13 only in blocks 0 and 4; 14 only in block 0. The scanner then skips to the next available block – if you set block 0 to 12, it asks for block 2 next, not block 1. For what each size code means, the Motorola fleet map table in BCT15X Talk Group ID Formats, Fleet Maps & Band Plans applies to the same scheme.

Motorola Type II Special Status Bits

Type II Motorola Smartnet systems use status bits for special transmissions such as emergencies, patches, DES/DVP scrambled transmissions and multiselects. A Motorola radio interprets them itself. The scanner sees them as different talkgroups, following this chart (talkgroup ID plus the number):

• +0 normal talkgroup, +1 All talkgroup, +2 emergency, +3 talkgroup patch, +4 emergency patch, +5 emergency multi-group, +6 unassigned, +7 multi-select (started by a dispatcher)
• +8 to +15 are the same functions for DES/DVP encrypted talkgroups (+8 DES/DVP encryption talkgroup, +9 DES All, +10 DES emergency, +11 DES patch, +12 DES emergency patch, +13 DES emergency multi-group, +14 unassigned, +15 DES multi-select)

Practical examples:

• If a user on talkgroup 16 presses their emergency button, everything on the talkgroup moves to the emergency status talkgroup (ID+2, here 18) until the dispatcher clears it.
• Many fire and EMS departments send tone-outs and alarms as multi-selects (ID+7). If your fire dispatch talkgroup is 1616 and they do this, those calls are on 1623. A user transmitting a multi-select on 1808 is received on 1815.

The Set Status Bit system option controls how the scanner treats these. See UBCD3600XLT Programming Systems & System Options.
