Interoperable IP Standards
Zetron's VoIP Radio Dispatch System (RDS) is a pure, end-to-end VoIP radio dispatching solution designed for applications requiring dispatcher access of multiple radios from geographically diverse, remote or backup locations. It is ideal for public & private utilities and air & rail transportation companies, whose radio networks and dispatching points are spread out. The architecture of the system makes it inherently distributed, avoiding the requirement to concentrate equipment in a single vulnerable site. The VoIP RDS is available in configurations that assure the high voice quality required for mission-critical communication. A P25 option is available, which supports AFSI, DFSI, and CSSI gateways. See P25 VoIP RDS spec sheet for details.
