XPT Trunking

Single-site and Multi-site Extended Pseudo Trunking (XPT)

XPT Delivers the Advantages of a Trunked Radio System at a Lower Cost


Developed exclusively by Hytera, the Extended Pseudo Trunking (XPT) system is based on the ETSI DMR Tier II Conventional Standard and adds capabilities normally found in higher cost Tier III trunking systems.

XPT makes DMR Tier II repeater systems more efficient to provide more channel capacity and adds valuable new features without the purchase of additional radio infrastructure hardware.



The XPT system is built from multiple Hytera repeaters at a site connected to each other by a simple network switch.  XPT supports a maximum of 8 repeaters per site to provide up to 16 voice channels, supporting over one thousand users. Each traffic channel can be customized to transmit voice or data.

XPT systems can also grow beyond the local footprint by connecting distant XPT systems via routed IP connections.

The Benefits of XPT Trunking

It is Easy to Migrate to XPT

Migrating from conventional DMR to XPT trunking is easy, especially if you are currently using Hytera DMR repeaters. XPT is as simple as adding the license to the repeaters, reprogramming the repeater, and adding a network switch for them to communicate. No need for forklift upgrades and completely throwing out the old system simply because of growing communication needs require additional system capacity.

XPT Adds Affordable Trunking Features

The XPT Trunking system allows customers to simulate a trunked radio system within available resources. XPT can trunk all 16 voice channels of a site. Another benefit of not requiring an FCC control channel is that that frequency can be used for voice traffic. This is even more important on smaller systems that may be beginning with two XPT repeaters. Not having to give up a voice channel for a Control Channel allows for maximum efficiency of the radio system.

Talkgroups can have access to multiple sites as well. Just like Tier III trunking, XPT allows for multi-site access, multi-site trunking as well as roaming between sites that overlap in coverage.

Does not Require a Dedicated Control Channel

A key advantage of an XPT Trunking system is that it enables efficiencies and dynamic channel allocation with less hardware and without an expensive Control Channel frequency. Unlike Tier III DMR Digital Trunking, XPT DMR Tier II Trunking does not use a dedicated Control Channel with an FCC FB8 control channel frequency that has guaranteed availability because it needs to be operational all the time to manage all the other channels on the system. This dedicated FB8 control channel requires a special FCC license, which is expensive and difficult to get in high-density metropolitan areas. This could be a non-starter for any new Tier III trunking systems.  XPT uses a series of beacons sent by each repeater to optimize channel usage and keep the radios in the field informed of system status.

XPT is Easy to Operate

Because XPT trunking is based off the DMR Tier II standard, operation is familiar with little interaction needed from the end user. Switching Talkgroups is as easy as changing the channel knob on the radio. No need to figure out the correct repeater to use, or where the rest of your Group is. XPT takes care of that on the backend keeping you in touch with your people with reliability and confidence.
