These interfaces are rack-mounting or slimline, desk-top intercom stations with analogue ports for linking Green-Go intercom groups to external analogue intercom systems or other audio equipment. They communicate over the network with other Green-Go digital intercom stations. Each station is connected to a network switch using standard Ethernet cabling. They can be powered over the network if the switch provides power over Ethernet.
The Green-GO 2-wire/partyline interface links the system into an existing analog ring/partyline system.
