The TOA N-8000RS Sub Station Interface Unit for RS-1 Series uses packet audio technology to connect up to 16 RS-1xx series call switches or door stations. It is crucial to use shielded twisted pair cables for connecting both call switches and door stations. Each port can supply 1W @25V to a door station or a 25V loudspeaker connected to a call switch. Each N-8000RS unit supports 2 voice links and needs either an IP master station or a connection to a 2-wire or 4-wire Exchange with at least one master station on the exchange.
