PowerTrunk25: P25 Infrastructure


P25 is a set of open standards as a result of combined efforts from Public Safety organisations in the United States, standardised under the TIA (Telecommunications Industry Association).
 
PowerTrunk25 features a powerful, field-proven end-to-end IP-based design, using standard networking equipment which reduces risk of obsolescence and lowers switching equipment costs. It is available both in conventional and trunking mode and is designed for a wide range of frequency bands (VHF, UHF, 800 MHz and 700 MHz). All these characteristics make PowerTrunk25 a revolutionary and innovative concept within the P25 market.
 
Our patented method for sending voice packets over IP has lower bandwidth requirements so customers can include additional applications on their IP backbones. Interoperability is fundamental to the design which includes interfaces to other PMR systems through the versatile NEBULA25 Connect module. In addition, VoIP connectivity makes integration with Computer Aided Dispatch and Voice Logging applications easier.
 
Teltronic’s P25 solution offers significant advantages. It is:
  1. Based on Teltronic’s field-proven technology developed for its successful NEBULA® (TETRA) line of products, with the same architecture, network elements and RF elements, inheriting the most advanced characteristics of this infrastructure. For example, the repeaters’ and controllers’ hardware supports TDMA access, allowing powerTrunk25 to migrate to P25 phase II only by a software change.
     
  2. 100% developed with Teltronic’s own technology which provides total flexibility for customisation
  3. Developed with Teltronic’s patented method for sending voice over IP/Ethernet that reduces inherent IP delays and optimizes bandwidth requirements.
