zd TOA MDESCRI PTION The N-8400RS 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 sets of twisted pair cables. The number of LAN—connected N—8000 system components such as the N—8400RS and IP intercom SUB STATION INTERFACE UNIT N—8400RS(CU) exchanges is 192 maximum in total. Connecting the unit to the LAN permits the sub-station to receive Paging calls and make calls to both the master station connected to the IP intercom exchange and the master station. [t 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.
