The ZXJ10 system can be served, with different configurations, as a local, transit, international center or media gateway, and its capacity can vary from several thousands of ports up to 1,000,000 subscriber lines (local office) or 250,000 digital trunks (transit office).

The ZXJ10 system has an abundant product series, which can not only satisfy the requirements for constructing gateway exchanges, tandem exchanges, toll exchanges and end offices, but also meet the requirements of access for communities, schools, enterprises, apartment buildings, commercial & dwelling buildings, etc.

With the structure fully -distributed in capacity, the ZXJ10 system, characters with flexible networking, rich services, high reliability, high integration and huge capacity, etc. The 64K single-T digital switching network (CPSN) card, using the ZTE-owned patent technologies, can be smoothly extended to a 256K switching network to meet the requirements of all large-capacity end offices, tandem offices and gateways. 

As one of the main products of ZTE Corporation, the ZXJ10 switching system has made great market success with years of application experiences. By October 2003, there are more than 55 million lines deployed in China, with a market share over 25%, serving carriers including China Telecom, China Unicom, China Railcom, China Netcom, Jitong and so on. Meanwhile, the ZXJ10 switching system has also been deployed in many countries and regions such as North American, Europe, South Asia, Southeast Asia, West Asia, Middle East, Community of Independent States and Africa, etc. The features it provided are very suitable for, not only the domestic but also the oversea carriers, to strengthen the network capabilities for a better service to customers.
