Line remote transmission switch
Line remote transmission switch
Product description: The multiplexing trunk remote transmission switch realizes point-to-multipoint networking, and voice and other services are transmitted through the multiplexing trunk.
share:
The BH series repeater equipment for remote transmission of trunked switching stations can achieve long-distance point-to-multipoint transmission of network and telephone signals through a twisted-pair cable. The twisted-pair cable includes trunked lines, telephone lines, mine cables, large-diameter cables, network cables, etc. It is suitable for emergency command communication, field command, underground broadcasting, underground positioning, railway infrared systems, etc. It is standard 1U, 19-inch rack-mounted.
