SmarTrunk
II™
Digital Signaling Trunking System
The SmarTrunk II
Digital Trunking System is widely used for trunked radio networks
at VHF and UHF frequencies.
With over 5,000 systems in eighty countries worldwide, SmarTrunk II
has become an industry-standard trunking protocol for business
dispatch and telephone interconnect applications in both public and
private systems. SmarTrunk II is supported by most of the world’s
leading manufacturers of two-way radio equipment, including Alinco,
Icom, Kenwood, Motorola, Standard, and Yaesu/Vertex.
Why
SmarTrunk?
SmarTrunk
II's robust digital signaling protocol performs well even in weak
signal conditions with high immunity to hackers and pirates. Best of
all, SmarTrunk II can be added to existing repeaters without
being affected by conventional users on the same channels.
This permits gradual conversion of your conventional repeater system
to an efficient, multi-channel trunked system.
SmarTrunk
II controllers and logic boards are available for over 40 makes
and models of portable radios from 10 different
manufacturers.
