- EAD-socket
EAD is an abbreviation for German "Ethernet-Anschlussdose". The EAD standard defines wall mounted
ethernet connection outlets that enjoy a higher reliability than standardT-connector s.EAD outlets have been developed from
TAE connector s for telephony applications but they are intended for connecting coaxial network cables like10BASE2 . A different mechanical encoding (Type "E") prevents mix-up with phone plugs.EAD cables are duplex connections replacing two thin-wire cables. The contacts of an EAD outlet are closed if no connector is plugged in. When a cable is plugged in, the normally closed contacts in the socket are opened so that signals pass through the loop cable.
