OptiX OSN 500 Multi-Service CPE OpticalTransmission SystemProduct Overview 1 Product Positioning and Features

1 Product Positioning and Features

About This ChapterThe OptiX OSN 500 is of a pure packet architecture, and supports a variety of service accessmodes. It completes Huawei's optical transmission system, and sharpens the competitiveedges of Huawei's optical transmission products.

1.1 Product Features

This section describes the equipment features in terms of architecture, technology, andnetworking.

1.2 Product Positioning

This section describes product positioning and networking application.

1.1 Product FeaturesThis section describes the equipment features in terms of architecture, technology, andnetworking.

Simple Architecture and High IntegrationThe OptiX OSN 500 is a type of case-shaped equipment. The dimensions of the chassis are:44 mm (H) x 442 mm (W) x 220 mm (D) Of a simple architecture and high integration, theOptiX OSN 500 can be installed in the following ways:

Cabinet-mounting (ETSI cabinet and 19-inch cabinet) Wall-mounting Desk-mounting Open-rack-mounting

Pure Packet Architecture and Multi-Service Transmission SupportThe OptiX OSN 500 supports service bearing in the packet domain. The solution improves

based on the service changes that take place due to radio mobile network evolution. Therefore,this solution can meet the transmission requirements of not only 2G and 3G networks, but

also the future LTE and 4G networks.





2

CES and ATM/IMA Service Support and Flexible NetworkingThe OptiX OSN 500 supports the circuit emulation service (CES) technology, allowing directtransmission of TDM E1 services in the packet domain.

ATM is a connection-oriented, fast packet switching technology. Integrating the advantages ofcircuit switching with those of packet switching, ATM is a standard broadband ISDN(B-ISDN) transfer mode. Inverse multiplexing for ATM (IMA) is a technology thatimplements inverse multiplexing for ATM.

End-to-End Service Configuration/One-Click Commissioning/One-Click FaultDiagnosis (TP-Assist)

Compared with legacy TDM networks, packet switched networks (PSNs) have the followingcharacteristics:

PSNs have flexible networking and complicated configuration, and therefore have high

requirements for operating and maintenance personnel. PSNs do not have complete overhead fields indicating their physical states, as compared

to TDM networks. If a fault occurs on a PSN, no simple and easy-to-use tool is availableto diagnose the fault.

Diversified network topologies and complicated technologies entail powerful OAMcapabilities.

To address the preceding concerns, the OptiX OSN equipment provides TP-Assistfunctionality to simplify operation and improve efficiency in service configuration,installation, commissioning, fault diagnosis, and routine maintenance. Table 1-1 describes theTP-Assist OAM system applied to PSNs.

An OptiX OSN 500 NE can automatically save its NE ID, extended ID, IP address, and subnet mask toits backplane. After a new system control, switching, and timing board replaces an original one, the NEautomatically uses the saved information. Therefore, you do not need to set the NE ID, extended ID, IPaddress, and subnet mask for the substitute board.

6 Network Management System

About This ChapterThe OptiX OSN 500 is uniformly managed by the transmission network management system(NMS) and local craft terminal (LCT) through the ETH port. The OptiX OSN 500 supportsthe Simple Network Management Protocol (SNMP).

The NMS maintains the OSN, SDH, Metro, and DWDM network elements (NEs) on an entirenetwork. The NMS can implement end-to-end configurations for packet services.

The OptiX OSN 500 complies with ITU-T Recommendations. The equipment adopts amanagement information model and an object-oriented management technology. With the

NMS, the equipment can exchange information with the NE software through thecommunication module to manage alarms and performance events in a centralized manner. Inaddition, end-to-end configuration on the management plane can be achieved.

The OptiX OSN 500 supports SNMPv2/SNMPv3, which allows a third-party NMS tomonitor equipment performance.

6.1 Network Management

This chapter describes the network management system, inter-NE communicationmanagement, and intra-NE communication management.

6.2 DCN Management

Reliable network management ensures proper running of a network, and thereforetransmission of network management data becomes very critical. The data communicationnetwork (DCN) is a network management data communication channel, with which users can

remotely manage and maintain NEs.

Figure 6-1 illustrates a network that has Huawei equipment deployed at different layers: NEs at sitesA-D are OptiX OSN 8800 NEs, NEs at site E are OptiX OSN 1800 NEs, and NEs at site F are OptiXOSN 550/500 NEs.

In Figure 6-1 ,

Network management system: U2000 and U2000 LCT Inter-NE communication management:

− The NEs at sites A and C are gateway NEs (GNEs) and are connected to the external DCN through a switchor router. All the other NEs are non-GNEs that communicate with the NMS through GNEs.

− The NEs between sites A and D are connected with fibers and use the HWECC or IP over DCC protocol toexchange information over ESC/OSC channels.

− The NEs between sites E and C are connected with fibers and use the HWECC or IP over DCC protocol toexchange information over ESC channels.

− The NEs between sites F and C are connected with fibers and use the HWECC or IP over DCC protocol toexchange information over inband channels.

− Some NEs between sites A and F (NEs connected to an optical or electrical transmission device, such as NEs at site B) are connected with network cables, and use the HWECC or IP over DCC protocol toexchange information over Ethernet channels (at NM_ETH ports).

Intra-NE communication management: The master and slave subracks implementintra-NE communication for each NE at sites A-D. One NE at site A has three subracks(one master is connected to two slaves).

Network management involves the following aspects:

Network Management SystemThe network management system (NMS) provides unified management for OptiX equipment.In compliance with associated ITU-T Recommendations, the NMS uses a standardinformation management model and object-oriented management technology.

The NMS manages alarms, performance, configurations, communication, security, andtopologies of the entire optical transmission system. The NMS also gives users end-to-endmanagement capabilities. An NMS helps to improve network quality, lower maintenance costs,and ensure efficient utilization of network resources.

The NMS includes two sets of network management software: iManager U2000 (U2000) andiManager U2000 LCT (U2000 LCT). The U2000 is usually installed at a networkmanagement center, and most equipment is managed remotely. The U2000 LCT provides theability to configure and maintain individual NEs. The U2000 LCT is usually installed on a PCfor local access to equipment.

Inter-NE Communication ManagementInter-NE communication management is implemented based on data communicationnetworks (DCNs). A DCN consists of NMSs, GNEs, non-GNEs, and the connections betweenthem. Both NMSs and NEs are nodes of a DCN. The DCN between the NMSs and NEs iscalled the external DCN, and the DCN between NEs is called the internal DCN.

An external DCN is a local area network (LAN) or a wide area network (WAN) and usesthe TCP/IP protocol for communication. It provides communication between NMSs and

between the NMS server and GNEs. An internal DCN uses the HWECC or TCP/IP protocol to provide communication

between NEs. NEs support inband DCN and outband DCN. The outband DCN usesDCC overhead bytes as physical DCN channels. The inband DCN uses Ethernet servicechannels as physical DCN channels.

6.2 DCN ManagementReliable network management ensures proper running of a network, and thereforetransmission of network management data becomes very critical. The data communicationnetwork (DCN) is a network management data communication channel, with which users canremotely manage and maintain NEs.
