The N-8000MI is a multi-interface unit designed for use with TOA's packet intercom system (IP networkcompatible intercom system) that employs the packet audio technology. Connecting the multi-interface to a local area network permits the ideal system for in-house or wide-area information transmission applications, such as paging, periodical broadcasts, and background music broadcasts, to be built between the multiinterface and IP intercom exchange or other multiinterface unit. The contact bridge function can be realized through contact input and output control. The N-8000MI also features the tie-line function to be connected to the EXES-2000 intercom system or the EXES-6000 system. A total of up to 192 multi-interface units and IP intercom exchanges can be connected to a network. The unit can be mounted in an EIA standard rack (1-unit size) or to a wall using the supplied bracket.
