Hytera RD625 VHF DMR Repeater + Duplexer

Hytera RD625 VHF DMR Repeater with Integrated Duplexer

The Hytera RD625 VHF DMR Repeater is designed according to the Digital Mobile Radio (DMR) open ETSI standard, offering seamless operation with both digital and analog signals.

Key Features:

• Flexible IP Networking:

  Connects to IP-based communication networks across multiple sites. The roaming function ensures continuous voice and data services across cells for radios in the network.

• VoIP Integration:

  Allows connection of existing VoIP telephone systems to the DMR radio network, enabling half-duplex conversations between DMR radio subscribers and telephone network participants. Supports individual and group calls for telephone subscribers.

• Seamless Analog and Digital Operation:

  Automatically switches between analog and digital modes based on the receiver signal, ensuring compatibility with current analog systems and removing the need for manual frequency and channel configuration.

• Adaptable Transmitting Power:

  Features an integrated power supply that switches to a backup DC supply from a sealed lead-acid battery during AC supply failures, providing a fail-safe solution for critical communications.
