SDH Equipment Ring Network Application Solution

With the development of industry communication, the SDH equipment transmission technology in traditional networks is also advancing rapidly. High-capacity, multi-type audio services and data services urgently require optical transmission equipment accessing the SDH network to possess ultra-large transmission capacity and complex networking capabilities. Accordingly, our company has independently developed an STM-16 level SDH optical transmission equipment, whose ultra-large transmission capacity and rich service interfaces can greatly meet the service transmission requirements in industry communication.

1 Solution Features

The requirements of the SDH equipment network for the optical transmission system include the following features:

² Ultra-large capacity service transmission capability;

² Complex networking capability;

² Strong expansion capability;

² Strong self-healing protection capability.

2 Application Solution

The solution shown in the figure above has the following features:

² Flexible networking structure: Multiple MSTP devices form two tangent ring networks of different levels. Each MSTP device in the ring network can form a star network or ring network with other SDH equipment, PCM equipment, and user equipment, enabling flexible networking in different application environments;

² Large service transmission capacity: Services between the two tangent ring networks can be cross-transmitted through the MSTP equipment at the tangent points, realizing non-blocking transmission of various services between different networks, effectively expanding the transmission capacity of the communication network;

² Strong transmission reliability: The SDH ring network has strong channel protection capability and abnormal alarm reporting capability. When an abnormality occurs in network transmission, the central end will detect it in a timely manner, providing a strong basis for fault location and timely troubleshooting;

² Large expansion potential: MSTP equipment has optical interfaces of different levels and rich service interfaces, supporting further expansion of complex networks;

² Easy maintenance: The gateway equipment in the network can perform online real-time monitoring and management of all other equipment in the entire network.
