N8521WU is a type of specialized communication system equipment developed by the manufacturers in the field of telecommunication. It is designed to provide integrated services for voice, data and IP transmission in different enterprise environments. By utilizing the latest technologies such as packet-switched networks and optical fiber technology, the N8521WU can provide a reliable and high-performance network platform for different businesses.

The N8521WU communication system is divided into two categories — the voice part and the data part. The voice part is a multi-service access system, designed to provide access to public switched telecommunication networks (PSTN) and other private networks, while the data part is designed to provide access to TCP/IP-oriented networks, such as the Internet. The N8521WU also comes with multiplexing features which are used to combine data streams from different users onto one physical line.

The main application fields of the N8521WU are in enterprises and rural areas. In enterprises, the N8521WU can be used to provide reliable communications between multiple sites that can be dispersed geographically, as well as for teleconferencing solutions. In rural areas, the N8521WU is often used in point-to-point networks, providing access to voice, data and IP services in areas with lower population density.

The working principle of the N8521WU is based on packet switching. In a packet switching network, data is divided into small chunks (or packets) and sent across the network to the destination. Each packet contains a source address, a destination address and the information that needs to be delivered. All the transmission nodes, including routers, switches and hubs on the network, will process the packets, as well as the error correction algorithms to confirm that all the information is received correctly.

Moreover, the N8521WU also uses the duplex mode of optical transmission. In this mode, two optical signals are sent on each fibre — one signal for data transmission and one for data reception. This ensures that the data transmission is kept low latency, highly secure and accurate, with no packet loss. In addition, the N8521WU also implements several services, such as call control, VoIP services, and other management services.

Overall, the N8521WU is an ideal communication system for different enterprise environments. It offers an integrated solution for voice, data and IP transmission, providing reliable and high-performance networks for businesses. With its features and benefits, the N8521WU can be utilized in different applications, such as enterprise networks and rural areas, for a reliable, secure and highly accurate communication system.
