Enhanced Trunking Solution
The ST-858 SmarTrunk Xpress Controller is the evolution of trunking systems. The ST-858 hardware has been designed with the latest technology in order to meet the highest standard requirements of the modern market. |
|
Flexibility
With over 6,000 systems sold over 17 years, SmarTrunk has been chosen by radio professionals in over 125 countries. We have always specialized in cost-effective and feature rich trunking systems which can be expanded to accommodate growth. The new SmarTrunk ST-858X controller is ready for the new enhanced SmarTrunk Xpress trunking protocol, delivering to the end user the possibility of employing this new technology for expanding older systems, or build up a brand new communications system with enhanced capabilities as Alphanumeric Caller ID, landline caller ID, high speed data bus, in field firmware flashing, expanded users database, and latest generation on telephone interfaces. In addition, its NVRAM storage keepsthe all the parameters and users database safe from blackouts.

Why Choosing SmarTrunk Xpress?
 ST-858 Controller Series, in combination with the new ST-965 and ST-965D logic board series, delivers a series of enhanced features to any existing conventional repeater system at the lowest cost in the market. Most conventional repeaters can be trunked with existing licenses, with no need of changing the existing radio equipment or infrastructure. In addition SmarTrunk Xpress allow GPS data and RAW data modulation over the air, which adds maximum value to any conventional LMR radio system. |
