Application of MSTP Transmission Equipment in Private Networks
Beijing Raytrans' MSTP transmission equipment provides various access methods such as SDH, PDH, and PCM on the user side, offering dedicated circuit lines based on N*64k, N*2M, 100/1000, STM-1, and STM-4 to meet different customer access needs. Currently, Raytrans offers more than 30 types of service boards to address various issues operators face at the access layer. For example, the PDH board provided by MSTP transmission equipment has been used to help expand optical cable capacity between urban and rural networks, solving the problems of increased county-township service capacity and insufficient optical cable resources. The total bandwidth capacity reaches up to 2.5G, further enhancing network access capability. The N*64k processing modules provided by MSTP transmission equipment have also been used in multiple local networks to help China Telecom and China Unicom complete the upgrade of their DDN networks, fully utilizing existing resources and continuing to create value for the two major operators.

Beijing Raytrans Digital Technology Co., Ltd. was the first in the industry to propose the dual-network dual-core network convergence concept, which has gradually been accepted by operators and has been applied on the live networks of China Telecom, China Unicom, and China Mobile — currently, the TDM core is mainly used for dedicated line access for major customers, while the IP core is used for access by small and medium-sized enterprises and internet cafes. Moreover, through the combined application of dual cores, it also provides operators with high-capacity, high-density customer center aggregation solutions. Under the future trend of network IPization, this architecture will greatly expand network access capability, laying the foundation for meeting high-bandwidth, high-capacity access demands, and significantly improving operators' return on investment.
