Key DMR Tier III Trunking System Benefits

Dedicated Management Channel

DMR Tier III trunking increases efficiency of channel usage with large groups of radios users using a dedicated control channel, managed by a server. This allows for maximizing channel frequency resources for high-volume call traffic and multiple user Talkgroups.

System Security

Some applications require a higher level of security for accessing the network, for those we offer ESN check (electronic serial number), authentication(both device and mutual), stun/revive (for a misplaced unit to still be able to be tracked), kill (completely disabling a stolen unit) and encryption.

Radio Management and Calling Features

The Hytera DMR Tier III System offers a multitude of different management services to allow radios to interact with the network. Radios are registered on the network for identification and can be configured with subscriber area restrictions and control channel reselection.
Two-Way DMR radios on a DMR Tier III system support voice and data services. The system provides standard voice services such as individual or private calls, group, emergency, broadcast, all call (this is a system wide call to everyone on the network), dispatcher, and and telephone calls. Data services include text messages, GPS data, status message (pre-configured messages), and emergency alarms. Additional radio features support on DMR Tier III systems include late entry into a group call, ambience listening, interrupt/override, dynamic group number assignment, voice recording, remote monitor, OTAP (Over the Air Programming), vote now, and group patching.

Mission Critical Redundancy

The system has several redundancy mechanisms available to ensure trouble-free operation and service to the end user. Considering that the MSO is the heart of the system, it supports local and geographical redundancy mechanisms to ensure continuous wide area operation. Other controller hardware can also be used in redundant configurations with several failsafe modes. All these configurations are scalable and can be adjusted at any time during the lifecycle of the system. So, you can start small and add redundancy as your system grows.

System Interoperability

Third party integrators can use the standard DMR AIS interface and the Hytera API for integrating dispatchers, vehicle location tracking systems and billing systems.
