  • The N-8000RS is a Sub-station Interface Unit designed for use with TOA’s packet intercom system (IP network-compatible intercom system) that employs the packet audio technology. Up to 16 sub-stations can be connected using 2-core shielded cables. Connecting the unit to the LAN permits the sub-station to receive paging calls and make calls to both the master stations connected to the IP intercom exchange and IP master stations. It can be mounted in an EIA equipment rack (1U size) with the use of an accessory rack mounting bracket or installed on a wall using an optional wall mounting bracket.
