The PUC supports interconnection and unified voice dispatch across multiple voice communication systems and terminals, including PMR systems such as digital trunked radio (DMR/TETRA), digital conventional, analog trunked radio, analog conventional, public network systems such as PSTN and PLMN, and VoIP systems. The PUC also features visualized dispatch based on the map and real-time poll of radios’ GPS data. With the cascading installation in different regions, the PUC enables flat and multi-level dispatch.
