Hytera DMR Trunking Pro


System Structure

The Hytera DMR Trunking Pro logically consists of base station system, service terminal, bearer network and mobile switching office (MSO). One MSO supports up to 100 sites, 800 carriers. A single base station supports up to 16 carriers.

MSOs are connected via IP transmission equipment so as to build a large scale network.

As the core of Hytera DMR Trunking Pro, MSO comprises a wide array of subsystem to enrich the application functions, such as Network Management System (NMS), Dispatching System and Digital Voicing Recording System (DVRS).
