Benefits
Ensure Secure and Reliable Railway Transportation
The IP hard pipe technology provides SDH-like transmission experience for services such as signal and GSM-R services, ensuring smooth service migration to the IP network.
The multi-level reliability protection, Huawei-proprietary hardware BFD detection, and patented VPN FRR technologies effectively prevent network faults from causing emergency stop or speed reduction.
Reduce Network Construction Costs
One device has two strata, IP hard pipe stratum and soft pipe stratum. They meet various service bearer requirements, and unified network construction saves costs.
The built-in PCM subcards supported by this solution avoid the need of individual PCM devices, simplifying network management.
Improve the Deployment and O&M Efficiency
The U2000 and uTraffic provide flexible network-wide O&M and fast service provisioning capabilities.
Multiple OAM techniques (such as IP FPM, TWAMP, and RFC 2544) are supported to quickly locate faults and monitor service performances in real time, effectively reducing the OPEX.
Support Future-oriented Network Evolution
Large-capacity devices meet high-bandwidth bearer requirements of emerging services and provide ubiquitous bandwidth connections.
The 1588v2 technology provides nanosecond-level clock synchronization precision and is not restricted by the environment. This solution perfectly solves the problem of LTE clock synchronization. This solution effectively protects network construction investment and facilitates future LTE-R upgrade and evolution.
