PTN Series Multi-Service Packet Transport Equipment

Product 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 ef-

ficiency, 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-preci-

sion frequency and time synchronization, uniform processing technology for multiple services, integrated microwave fea-

tures, 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).

Product Appearance

The PTN 950 box is 2U in height, and provides two multi-function control board slot and six multi-service interface

board slots. The multi-function control board (control/switching/clock processing) and the service interface board use

the horizontal interpolation layout in the subrack.

Product Feature

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 mul-

tiple 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, supports abundant layer 3 protocols and L2 VPN/L3 VPN features, and meets the re-

quirements for the LTE-oriented evolution of bearer networks.

Fast service activation under any environment based on the mult-media access (such as the fiber, mi- ●

crowave, 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 net-

work 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 (ACR) clock, and

network time reference (NTR) clock. It supports the microwave network to transmit the clock. The all-media clock solu-

tion 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 op- ●

eration capability of packet networks

Based on the high-performance transport 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. The T2000 NMS can be smoothly up-

graded to the uniform U2000 NMS of new-generation network products in the future.

Multiple designs, greatly facilitating the debugging and maintenance and saving the cost of the net- ●

work construction and O&M

The PTN 950 V1R1 exempts the customer from the necessity of field software debugging and enables one-time de-

ployment by loading configurations through CF card, remote deployment or debugging through wireless modems. The

PTN 950 V1R1 supports scattered loading and concurrent activation based on software upgrade, and can upgrade 400

NEs per day. In addition, the PTN 950 V1R1 greatly reduces the O&M cost by combining multiple maintenance-free de-

signs, such as the air filter and automatic recovery for replacement of faulty boards.
