Together with the intelligent DAMM TetraFlex® software, simple site expansion is possible, even while in operation. The 100% IP-based technology provides full architectural network flexibility with all network components connected in a single state-of-the-art infrastructure without a central switch.

The BS421 is part of our single-technology portfolio but can be fully integrated into any of our multi-technology products. The system is easy to set up and fast to deploy due to the simple plug-and-play design.

IP65 protection makes the DAMM Outdoor System ideal for installation in harsh environments and its compact design enables direct mounting on antenna masts, buildings and towers. This reduces installation costs and feeder loss considerably while providing an ideal solution for rapid, vehicle-based deployment.

DAMM Outdoor Systems meet the highest requirements for reliability as they feature full support for battery backup, as well as redundant controllers, power supplies and carriers. Information to all sites in the network is replicated through the decentralised architecture, ensuring no single point of failure.

DAMM TetraFlex is supplied with Application Gateways for easy access to the Application Programming Interface (API), Packet Data Gateways and Voice Gateways. This enables straightforward development of customer-designed applications or integration to control room equipment and existing telephone systems.

As an independent TETRA infrastructure provider, DAMM base stations are IOP-certified for full compatibility with all TETRA terminals, providing the client with an option to freely choose a favourite terminal brand.

A wide range of application software is available with the DAMM TetraFlex system such as Voice and Data Log System, Dispatcher, Enhanced Bridge and a comprehensive Network Management tool that includes subscriber management and network performance statistics.
