PTN Series Multi-Service Packet Transport Equipment
Overview
With the rapid growth of packet services, the SDH transport network that is based on the rigid TDM channel and fixed granularity grooming encounters challenges in areas, such as service grooming and processing, bandwidth efficiency, and network scalability. To meet the trend of rapid-growing packet services in a transport network, Huawei presents a packet transport platform, that is, the OptiX PTN series, which are oriented to the all-IP evolution. The OptiX PTN 950 is a multi-service access box located at the hub node on the access layer of the transport network, and builds an end-to-end metropolitan packet transport network with other PTN series products.
The PTN 950 focuses on the resource, cost, and service challenges for the carriers on the access layer during the mobile network evolution. The PTN 950 provides the customers with a leading mobile bearer solution in 2G/3G/ LTE era based on Huawei's industry-leading mobile bearer concept "Any Media" and the LTE-oriented packet technology platform.
The PTN 950 provides multiple unique functions, such as any media access, any media clock transmission, high-precision frequency and time synchronization, uniform processing technology for multiple services, integrated microwave features, and offload function for the voice and data services. Combined with the easy and efficient network management system (NMS), the PTN 950 provides the customers with the best solution to reduce the TCO of the network construction, save the bandwidth cost, and improve the efficiency of the deployment and operation and maintenance (O&M).
Features - LTE-oriented all-IP architecture, compatible with multiple services, protecting the network investment
The PTN 950 adopts an all-packet architecture to construct a platform for the uniform access and bearer of multiple services（TDM/ATM/Ethernet/IP）in the all-IP era, improve the network flexibility and the transmission efficiency, build a reliable carrier-class packet bearer network, and reduce the TCO of the network in terms of the structure. The PTN 950 is based on the MPLS/MPLS-TP series standards. It uses connection-oriented packet technology, features with high-bandwidth and low-delay, and meets the requirements for the LTE-oriented evolution of bearer networks. - Fast service activation under any environment based on the mult-media access (such as the fiber, microwave, and copper cable)
The PTN 950 provides E1 (TDM/IMA) and FE/GE (optical/electrical) and channelized STM-1 interfaces at the client side (UNI), and channelized STM-1, FE/GE (optical/electrical), E1 (ML-PPP), microwave, and xDSL interfaces at the network side (NNI). In this case, adequate resources are available for fast network deployment. Especially, the PTN 950 integrates the microwave features, provides microwave interfaces, and achieves the optimal evolution cost and fast activation for the initial services of the network deployment. - All-media clock solution solving the mobile bearer timing problem
The PTN 950 provides the IEEE 1588v2 clock, synchronous Ethernet clock, adaptive clock recovery (1588 ACR) clock, and network time reference (NTR) clock. It supports the microwave network to transmit the clock. The all-media clock solution fully meets the clock requirements for multiple access media in various networks, solves the clock synchronization problem of mobile packet bearer networks, and reduces investment in network synchronization. - Visual NMS, one-key service provision, and fault location in seconds, thus greatly improving the operation capability of packet networks
Based on the high-performance transport U2000/T2000 NMS, the PTN 950 achieves visual graphics management, end-to-end one-key provision for BTS services, and fast fault location within 30 seconds based on the convenient service configuration flow and the perfect OAM and fault detection mechanism. The PTN 950 greatly improves the O&M efficiency and enhances the manageability, operability, and maintainability of packet bearer networks. In addition, the NMS supports the uniform management of the PTN, microwave, MSTP, WDM equipment. Thus, the PTN 950 effectively avoids the delimitation dead zone between multiple NMSs and greatly improves the network operation capability. - Multiple designs, greatly facilitating the debugging and maintenance and saving the cost of the network construction and O&M
The PTN 950 V1R2 exempts the customer from the necessity of field software debugging and enables one-time deployment by loading configurations through CF card, remote deployment or debugging through wireless modems. The PTN 950 V1R2 supports scattered loading and concurrent activation based on software upgrade, and can upgrade 400 NEs per day. In addition, the PTN 950 V1R2 greatly reduces the O&M cost by combining multiple maintenance-free designs, such as the air filter and automatic recovery for replacement of faulty boards.
