4. Embedded applications

This section describes the applications usually found on buildings. Depending on the size of the building, these generic applications or sub-systems of the telecommunication system include a greater or lesser number of user terminals, or even none at all (no combat system on the smallest units, for example).

• Voice subsystem

  This subsystem takes into account the transmission of voice within the building via :

  • telephony

  • intercom

  • broadcasting orders and alerts (using appropriate frequency combinations),

  • and modulation of radio links.

• External transmission management subsystem
