The TOA N-8000AL IP Intercom Telephone Interface Unit serves as a telephone interface unit designed for TOA's packet intercom system. It makes use of packet audio technology and functions smoothly within IP networks. This unit provides an analog telephone line interface for connectivity. When incorporated into the LAN, the analog telephone can mimic the functions of an intercom master station. Installation is simple, as it can be mounted in an EIA equipment rack (1U size) with an optional rack mounting bracket or on a wall using an optional wall mounting bracket.
