China Mobile improves O&M efficiency with ZTE bearer network PTN intelligent tools

China Mobile’s Jiangsu arm Jiangsu Mobile has adopted a new standard for its bearer network intelligent operations and maintenance (O&M) technology from ZTE.

The vendor’s packet-based transport network (PTN) technology was adopted following its successful performance in stress tests originally conducted in June. To improve the efficiency of the network’s emergency response, Jiangsu Mobile conducted a PTN transmission equipment emergency rehearsal at its branches in 13 cities.

ZTE’s PTN’s fast failure recovery tool is customisable, adapting to the quantity of equipment and various engineering scenarios. When service interruption occurs following a link failure, it takes three minutes on average to manually recover service. With the ZTE PTN recovery tool, it takes just 30 seconds to recover service, a five-time increase above average.

By setting the ZTE PTN intelligent O&M tool as a standard, it suggests the Nanjing provincial company will be able to promote the development of all transmission vendors PTN O&M tools, which will improve the equipment maintenance efficiency of the whole province.

ZTE is dedicated to PTN network O&M research and has developed a series of PTN O&M tools including a network expansion and contraction tool, a service cutover tool, a failure diagnosis tool, a tunnel migration tool and an optical power analysis tool. All of these tools have been deployed commercially.
