The BS421 is part of our single-technology portfolio, but can be fully integrated into any of our multi-technology products.

Easy to install – anywhere

The system is easy to set up and fast to deploy due to the simple plug-and-play design. The 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 at the same time providing an ideal solution for rapid, vehicle-based deployment.

Secure and failure tolerant

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 decentralized architecture ensuring no single point of failure.

Unlimited application integration

DAMM TetraFlex is supplied with Application Gateways for easy access to the Application Programming Interface (API), Packet Data Gateways and Voice Gateways. This enables straight-forward 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 you with the option to freely choose your favourite terminal brand.

Wide range of advanced software tools

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
