MOTOTRBO


Contents

General Information

MOTOTRBO is a Motorola digital radio product marketed primarily to business/industrial users. The format is based on, and compatible with the European 2-slot DMR standard and uses Time Division Multiple Access (TDMA) to effectively accommodate two simultaneous users. A single 12.5 kHz channel is able to carry two simultaneous and independent conversations, or simultaneous and independent voice and data paths each with 6.25 kHz equivalency, however the bandwidth of DMR exceedes the maximum required for UHF 6.25 kHz channel centers. Operation of different talkgroups and talkpaths similar to trunking is possible, as is wide-area operation through IP connectivity. MOTOTRBO transceivers and repeater stations may be retrocompatible with analog FM using CTCSS or CDCSS.

Emission designators for MOTOTRBO: 7K60FXE (voice), 7K60FXD (data).

MOTOTRBO is based on the following ETSI standards:

Additional information on DMR is available through the Digital Mobile Radio Association.

Monitoring TRBO

You can use the following to monitor a MOTOTRBO transmission.


Uniden Scanners


Whistler Scanners


Other Receivers / Scanners
  • AOR DV-1 (note: No trunking)
  • Using DSD or DSDPlus, along with a discrimintor tapped scanner. DMRDecode may be used to view system information
  • Using DSD or DSDPlus with many SDRs. DMRDecode may be used to view system information
  • Monitoring using DMRDecode, along with other utilities, is discussed here


Some abbreviations you might see while decoding with utilities like DMRDecode
  • CACH is Common Announcement Channel
  • TACT is TDMA Access Channel Type
  • LC is Link Control
  • EMB is Embedded signalling field
  • CSBK is Control Signalling Block

MOTOTRBO Features

  • IP Site Connect
    • Connects multiple conventional TRBO repeaters in a wider-area network
  • Privacy
    • Basic: 8-bit (256 combinations)
    • Enhanced: 40-bit (1,099,511,627,776 combinations)

MOTOTRBO Trunking

The standard includes provisions for trunking:

Motorola has developed three trunking systems for MOTOTRBO: Connect Plus, Capacity Plus, and Capacity Max.

  • MOTOTRBO Connect Plus
    • Multi-site trunking network that can handle up to 100 registered talkpaths and 30 simultaneous calls
    • Each site has a fixed control channel
    • XRT 9000 Gateway
    • XRC 9000 Controller
  • MOTOTRBO Capacity Plus
    • Single Site Capacity Plus allows voice and data communication at a single site.
    • Multi Site Capacity Plus allows voice and data communication up to 15 sites.
    • Up to 12 digital voice talk paths with three sites or less.
    • Up to 6 digital voice talk paths with 15 sites.
    • Allows up to 24 additional dedicated data paths
    • No fixed control channel, instead has a "Rest Channel" (the next available channel, sounds like a control channel) which can hop around. In a standard installation, the rest channel starts at Channel 1 and works up to the highest channel, then returns to Channel 1 and begins the rotation again.
  • MOTOTRBO Capacity Max
    • Capacity Max allows voice and data communication up to 15 sites.
    • A system can support up to 15 sites with up to 3,000 users per site and up to 100 voice talk paths.
    • Capacity Max is fully compliant with the DMR Tier III mode of operation.
    • Powerful management tools give you complete control over the system – all from a single workstation
    • You can also provision a second control channel per site for ultra-high system availability.
