The newly expanded N-8000 Series IP Network Intercom offers flexible communications for up to 3,072 stations on existing corporate local and wide area data networks. Built on TOA's proven NX-100 network audio technology, the new IP Intercom products occupy minimal network bandwidth (130 kbps maximum) for station-to-station calls and can be controlled and monitored through software or web browser. Programmable system functions include 192 paging zones, time-based call forwarding and scan monitoring. The N-8510MS IP Master Station provides the same functionality as the 2-wire N-8010MS. The N-8540DS IP Indoor Sub-station also connects directly to the network and includes a vandal-resistant call-switch and control output for door release. A weather-resistant version is also available, model Q-N-8540WP IP Outdoor Sub-station.
