The TBC-6816U series 16-Channel Telephone Multiplexer is a new generation of highly integrated single board PCM group multiplexing equipment based on proprietary software and thick film technology. The equipment can simultaneously transmit 16-channel telephone interfaces through optical fiber and transmit E1 signals, Audio signals, data signals, etc. (The above interfaces are based on customer requirements flexible customization, not the standard configuration). The Telephone Multiplexer Series equipment is mainly used for transmission through the network, telephone and program-controlled switches to achieve the connection. Equipment is widely used in: Internet cafes, small and medium-sized companies, highways and temporary construction sites need to address the needs of the rapid telephone and data services, as well as the ongoing construction of the village through telephone access and so on.
