multi dwelling unit (MDU)

In home and building cabling, there are communications-specific services for telephone and Internet such as Internet telephony( VoIP) or Internet television( IPTV), broadcast services for radio and television, and monitoring and control services for the heating and alarm systems.

If the broadcast and communication services are networked via different transmission media - via TP cable, fiber optic cable and coaxial cable - then the Multi Dwelling Unit (MDU) ensures that the services can be tapped at several outlet sockets in a larger apartment or multi-family building.
