The IP Transmitter & Receiver Enclosures work together for building-to-building communication. The IP Transmitter Enclosure captures the audio & data signals from the data cable and transmits them over IP to the IP Receiver Enclosure. The IP Receiver Enclosure then injects the data and audio into the data cable in the remote area or building. Multiple Receivers can be connected to the same Transmitter to connect multiple arears or buildings.
