Recently, ZTE's bearer networkPTNintelligent operation and maintenance tools have been used in Jiangsu Mobile's province-wide "Transmission Emergency Route Adjustment Exercise" to great effect, and have been highly evaluated by Jiangsu Mobile, which has listed them as a benchmark and recommended that they be promoted for use on a large scale.

In June 2016, in order to improve network emergency response efficiency, Jiangsu Mobile organizedemergency failure drills for transmission professionalPTNequipment in 13 municipal branches across the province.Customized to fit the number of users and engineering scenarios,ZTE's PTNfault resuscitation tool can quickly complete faulty link resuscitation when link failure causes service interruption. It is estimated that it usually takes more than 3 minutes for a service to be put through manually, but with the ZTEPTNFault Rescue Tool, a service is usually put through in less than 30 seconds, which improves the efficiency of a service by 5 times. In addition, the tool supports the relocation function, so that after the link fault is repaired, the service can be relocated back to the service that has been put through with one click. In addition, the tool supports the relocation function. After the link fault is repaired, the service can be relocated with one click. The ZTEPTNFailover Tool not only greatly improves the efficiency of failover, but is also easy to operate. Users only need to select the failed link and set an alternative route in the network management, so that they can quickly find the tunnels involved and quickly calculate an emergency route for the selected tunnels, thus realizing the rapid failover of services. When the service is completed, the system will automatically save it as a robocall task, and users can view the robocall service through the robocall task, and when the link failure is repaired, the robocall service can be relocated back to the state before the robocall.

In this regard, Jiangsu Mobile gave a high evaluation. The routing adjustment exercise report released by Jiangsu Mobile pointed out, "In this routing adjustment, Nanjing Company used the new function of ZTE network management: fault robbing tool, which embodies a better effect, and can utilize the redundant resources of the existing network to realize the fast fault robbing of large-volume services." In addition, Jiangsu Mobile listed ZTEPTNintelligent operation and maintenance tools as a benchmark, and suggested that the provincial company promote each transmission manufacturer to strengthenthe development of PTNoperation and maintenance tools to improve the province's maintenance efficiency.

ZTE and China Mobile have been working closely onPTNnetwork operation and maintenance issues for a long time,and have developed a series ofPTNoperation and maintenance tools, including network expansion and contraction tools, service cutover tools, troubleshooting tools, tunnel migration tools, and optical power analysis tools, which have been successfully deployed commercially in many regions. ZTE's PTNFault Rescue Tool, an innovation result of cooperation between ZTE and Nanjing Mobile in 2015, has been highly recognized by many customers for its powerful functional characteristics, efficient operation capability, and excellent maintainability, which effectively improvesthe efficiency ofPTNnetwork operation and maintenance, and jointly promotes the win-win development between ZTE and its customers.
