N-8000CO C/O Interface Unit
N-8000CO CE
The N-8000CO is a C/O interface unit designed for use with TOA's packet intercom system (IP network-compatible intercom system) that employs the packet audio technology. It has an analog central office line circuit, allowing the intercom station to make and receive calls to and from the telephone line. Connecting the unit to the LAN permits paging calls through analog subscriber line to be made and the equipment connected to the N-8000MI and N-8000DI to be controlled. 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.
