Such integration and verification service ensures the proper functioning of equipment and designs, helps identify technical problems, and verifies that products and network architecture can help the customer achieve the expected business and technologic results. Test case preparation: Based on the customer's requirements set in the tendering documents and contracts, Huawei designs equipment factory acceptance test (FAT) cases. Once approved by the customer, the FAT cases will become the major reference for implementing factory acceptance. FAT organization: Schedules FAT trips for customers, arranges accommodations and meals, and makes FAT plans according to the requirements specified in the contract. The equipment provider is responsible for producing the involved equipment and preparing the FAT site. Joint acceptance test: Works with customers to perform the FAT cases that have been approved by both sides and ensures that the test results are accepted and signed by customers Test Bed The test bed service can provide customers with 100% mirroring for communication subsystems. Customers can purchase Huawei products to set up a test bed, on which they can simulate various operations, such as service cutover, software upgrade, hardware upgrade, and system commissioning. The test bed service provides reliable and authentic reference to customers before they decide to perform operations on their commercial networks. This service greatly reduces the operational risks of customers' networks, allowing them to achieve excellence in business operations EMC and RAMS Huawei Railway Communication Service solution complies with the latest process standards in the industry. The whole design process is controlled through EMC and RAMS plans, which ensure that the design service meets the highest industry standards applicable to customers. Page 7 of 12

10 4 Optimization Service 4.1 Purpose Due to the slight differences between on-site projects (or the actual situation of service) and design solutions, the existing network conditions, especially the Wi-Fi coverage, network, and video monitoring systems, should be optimized to meet the demands of customers or services in terms of performance and coverage. Such is called network service, and is normally conducted after customers have approved the technical designs and the projects have been implemented. 4.2 Contents Sub-service modules of service are as follows Wireless network Multi-service bearer network Wireless Network Optimization Generally speaking, after the project implementation, items in the following table would undergo comprehensive performance to improve the performance and reliability of involved radio subsystems.

11 4.2.2 Multi-service Bearer Network Optimization In the event of modifications to designs or changes in the on-site environmental conditions after the project implementation, gaps may exist between actual implementation and design specifications. In this case, the related network subsystems (IP network systems and transmission systems) should be optimized. IP network Transmission network subsystem QoS System redundancy Device-level protection Network-level protection Networking topology Service bandwidth The QoS for one particular service can help ensure that the SLAs of different services are met. System redundancy could be realized by means of double uplinks, stacking, etc. The system RAMS requirements can be satisfied by optimizing device-level protection configuration. The system RAMS requirements can be satisfied by optimizing network-level protection configuration. The system RAMS requirements can be satisfied by modifying the networking topology, for example, changing 1+1 MSP chains to MSP rings or SNCP rings. The requirements for real-time bearing of HD videos can be satisfied by modifying the bandwidth of the CCTV subsystem. 5 Training Service 5.1 Purpose To help customers better utilize and maintain Huawei-provided and third-party devices and services, Huawei provides multi-dimensional training services to customers, including product training, system training, and customized training. 5.2 Contents Sub-service modules of service are as follows Product training System training Customized training Page 11 of 12
