Dynamic Subscriber Assignment is an intelligent feature that facilitates quick and easy system setups or migration of terminals from one infrastructure to another. DSA terminals are registered securely, but with minimal infrastructure subscriber maintenance. DSA follows DAMM's strategy to invent solutions for mission-criticial operations such as disaster scenarios.
The TetraFlex Dynamic Subscriber Assignment is an interesting feature that, together with the scalable and compact TetraFlex system, provides a future-oriented safe solution to secure communications at 'black spots' where currently established TETRA infrastructures, such as country or region-wide public safety networks have lack of coverage. The feature makes it possible for subscribers of any TETRA 'home' network to automatically be included in the TetraFlex 'guest' network within seconds. With a dynamic and automatic registration process no subscriber management is needed. While saving operational costs, users also benefit from an instant and full end-to-end encrypted communication with a full set of TETRA features available.
