Extended Pseudo Trunk


Extended Pseudo Trunk

XPT (Extended Pseudo Trunk) is a scalable digital trunking solution that allows you to increase the capacity of an existing conventional DMR system by simply upgrading the current RD98XS repeater and DMR radios. XPT connects a larger number of users with voice and data turning your conventional DMR System into a virtual trunking system. XPT allows faster access to the system for multiple users from various departments, this can increase productivity, enhance customer service and provide better dispatching to security personnel responding to emergencies.



-- No dedicated control channel

In contrast to the classic trunked radio, Hytera XPT does not use any control channels. All available radio channels are utilized for the communication. On top of that, all channels are managed by the mobile radio infrastructure. The benefit: A manual channel selection at the radio is no longer required. Open channels are automatically determined for call requests. This allows Hytera XPT to combine the advantages of DMR Tier II with the mobile radio properties of state-of-the-art and powerful trunked radio systems.

-- Simple expansion, flexible networking

All repeaters in the XPT system are connected with each other via an IP network. As a result, besides the XPT repeaters, you only need IP switches and an antenna connection suitable for your purpose in order to set up your mobile radio system. PC hardware is not required for the mobile radio system since calls are set up directly in the XPT system. No central system controller node is required.

If your requirements for your professional mobile radio should change, it enables you to quickly respond in order to increase your mobile radio capacity. To do so, you only have to expand your repeater site by additional repeaters and connect them to your IP network. 

-- Simple migration from DMR Tier II to XPT

Are you already using conventional DMR radio from Hytera (DMR Tier II)? Then you are well prepared! Your existing DMR mobile stations and RD98XS repeaters can be upgraded to XPT without any complications via a license upgrade. This keeps your investment safe and you do not have to purchase new radios. 

-- Large capacity

One XPT site consists of up to 8 voice repeaters and 8 data repeaters, each repeater can provide 2 logical channels, thereby the system is able to provide up to 32 communication channels in each site. 

-- Dedicated data revert channel

You can specify that some channels are only used for RRS/GPS or quick GPS, so there will not be any conflict between voice and data upload. 

-- Improved system security

With Dynamic Authentication, terminals in the system must use a dynamic authentication code generated by the basic key to get authenticated from the system.

-- Auto detect interference

To guarantee reliable communication channels for terminal users, repeater in XPT systems can detect the interference from air interface and notify the terminal to switch to another available channel. 

-- System load balance

With home repeater concept, you can manually change the load balance of each repeater in the system and improve the call setup time with lower conflict ratio. 

-- Fault tolerance

IP Router Fail

Repeaters in each site will fall back to single-site operation mode, radios in each site can talk with radios in the same site. 

-- LAN Switch Fail

Each repeater starts working as a two channels trunking system. 

-- Repeater Fail

Radios in failed repeater channel will switch to another repeater automatically, system remains operational with less capacity.
