The TOA N-8000CO IP Intercom C/O Telephone Line Interface Unit serves as a C/O interface unit within TOA's packet intercom system, incorporating packet audio technology that is compatible with IP networks. Featuring an analog central office line circuit, this unit enables intercom stations to establish telephone line calls. When connected to the LAN, it facilitates paging calls via analog subscriber lines and offers control over devices linked to the N-8000MI and N-8000DI. The N-8000CO can be mounted in an EIA equipment rack (1U size) using an optional rack mounting bracket or placed on a wall with a wall mounting bracket (optional). Please be aware that the rack mount kit is available separately. For rack mounting, utilize TOA MB-15B-BK (one unit per rack space) or MB-15B-J (two units per rack space).
