N-8000AL Telephone Interface Unit


N-8000AL CU

The N-8000AL is a Telephone interface unit designed for use with TOA's packet intercom system (IP network-compatible intercom system) that employs the packet audio technology. It has a single telephone line interface, allowing an analog telephone to be connected. Connecting the unit to the LAN permits the analog telephone to be operated in the same manner as the intercom master station. It can be mounted in an EIA equipment rack (1U size) with the use of an optional rack mounting bracket or installed on a wall using an optional wall mounting bracket.
