CDR Radio Distribution Cabinet (Passive MS71) 

The purpose of Article MS71 is to enable rescue operators, especially the fire brigade, to fully use their own radio communication resources in parts of establishments open to the public, located in the basement, areas with generally no radio wave propagation from the outside.

These resources work either independently (in direct mode) or are based on INPT (Infrastructure Nationale Partageable des Transmissions - shareable national transmission infrastructure) dedicated to rescue and security services.
