PTN Solutions Assist State Grid in Informatization Construction

High-bandwidth office services, such as video conferences, are carried and logically isolated on PTN networks.

Network bandwidth utilization is improved, configurations are flexible, highly reliable video services are quickly deployed, and network construction costs

are reduced.

The solutions address demands for additional future high-bandwidth and intelligent services.

In an intelligent power grid, bandwidth demands surge and bandwidth on

SDH networks is obviously insufficient.

The service mainly carried currently is the important client services like bank.

According to SingTels construct plan, the mobile service will be also switched

to the PTN network.

SDH-like O&M help transport background engineer to learn. Super Protection equipment level and network level ,Guaranteed high

reliability in the mode of packet transport.

Mobile Broadband (MBB) services and customer E-line services require

high bandwidth.

SingTel demands SDH-like network protection and OAM for future PTN

networks.

Huawei's PTN solutions help achieve unified transmission of mobile, private line,

and Wireless Local Area Network (LAN) services.

The statistical multiplexing function meets surging bandwidth demands and

ensures fast access and deployment of private line services.

Multiple services are carried in a unified manner, reducing network construction

investments and later O&M costs, and improving network maintenance efficiency.

Users of private line services such as bank have increased and bandwidth

demands have surged; therefore, service-transmission methods must be

optimized to improve efficiency and reduce investments in private line networks.
