1 Product Positioning and Features

About This Chapter

The OptiX OSN 500 is of a pure packet architecture, and supports a variety of service access

modes. It completes Huawei's optical transmission system, and sharpens the competitive

edges of Huawei's optical transmission products.

1.1 Product Features

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

networking.

1.2 Product Positioning

This section describes product positioning and networking application.

1.1 Product Features

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

networking.

Simple Architecture and High Integration

The 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, the

OptiX 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 Support

The 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.

CES and ATM/IMA Service Support and Flexible Networking

The OptiX OSN 500 supports the circuit emulation service (CES) technology, allowing direct

transmission of TDM E1 services in the packet domain.

ATM is a connection-oriented, fast packet switching technology. Integrating the advantages of

circuit switching with those of packet switching, ATM is a standard broadband ISDN

(B-ISDN) transfer mode. Inverse multiplexing for ATM (IMA) is a technology that

implements inverse multiplexing for ATM.

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

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

characteristics:

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 available

to diagnose the fault.

Diversified network topologies and complicated technologies entail powerful OAM

capabilities.

To address the preceding concerns, the OptiX OSN equipment provides TP-Assist

functionality to simplify operation and improve efficiency in service configuration,

installation, commissioning, fault diagnosis, and routine maintenance. Table 1-1 describes the

TP-Assist OAM system applied to PSNs.

The packet switching unit of the CSHD board works with a service board to implement MPLS

functions.

Setup mode: static tunnels

Protection: 1:1 tunnel APS

OAM: supports MPLS tunnel OAM and MPLS-TP tunnel OAM. MPLS tunnel OAM

complies with ITU-T Y.1711, and MPLS-TP tunnel OAM complies with ITU-T G.8113.1.

An OptiX OSN 500 NE can automatically save its NE ID, extended ID, IP address, and subnet mask to

its backplane. After a new system control, switching, and timing board replaces an original one, the NE

automatically uses the saved information. Therefore, you do not need to set the NE ID, extended ID, IP

address, and subnet mask for the substitute board.

This section provides the power consumption and heat consumption of the equipment.

Power Consumption Maximum power consumption: 75 W

Typical power consumption: 35 W

Maximum heat consumption: 256 BTU/h

Typical heat consumption: 120 BTU/h

In the case of OptiX OSN 500 equipment, power consumption is generally transformed into heat

consumption. Hence, heat consumption (BTU/h) and power consumption (W) can be converted to each

other in the formula: Heat consumption (BTU/h) = Power consumption (W) / 0.2931 (Wh).

6 Network Management System

About This Chapter

The 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 supports

the Simple Network Management Protocol (SNMP).

The NMS maintains the OSN, SDH, Metro, and DWDM network elements (NEs) on an entire

network. The NMS can implement end-to-end configurations for packet services.

The OptiX OSN 500 complies with ITU-T Recommendations. The equipment adopts a

management information model and an object-oriented management technology. With the

NMS, the equipment can exchange information with the NE software through the

communication module to manage alarms and performance events in a centralized manner. In

addition, end-to-end configuration on the management plane can be achieved.

The OptiX OSN 500 supports SNMPv2/SNMPv3, which allows a third-party NMS to

monitor equipment performance.

6.1 Network Management

This chapter describes the network management system, inter-NE communication

management, and intra-NE communication management.

6.2 DCN Management

Reliable network management ensures proper running of a network, and therefore

transmission of network management data becomes very critical. The data communication

network (DCN) is a network management data communication channel, with which users can

remotely manage and maintain 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 switch

or 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 to

exchange 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 to

exchange information over ESC channels.

− The NEs between sites F and C are connected with fibers and use the HWECC or IP over DCC protocol to

exchange 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 to

exchange information over Ethernet channels (at NM_ETH ports).

Intra-NE communication management: The master and slave subracks implement

intra-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:


Transmission System




30

Network Management System

The network management system (NMS) provides unified management for OptiX equipment.

In compliance with associated ITU-T Recommendations, the NMS uses a standard

information management model and object-oriented management technology.

The NMS manages alarms, performance, configurations, communication, security, and

topologies of the entire optical transmission system. The NMS also gives users end-to-end

management 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) and

iManager U2000 LCT (U2000 LCT). The U2000 is usually installed at a network

management center, and most equipment is managed remotely. The U2000 LCT provides the

ability to configure and maintain individual NEs. The U2000 LCT is usually installed on a PC

for local access to equipment.

Inter-NE Communication Management

Inter-NE communication management is implemented based on data communication

networks (DCNs). A DCN consists of NMSs, GNEs, non-GNEs, and the connections between

them. Both NMSs and NEs are nodes of a DCN. The DCN between the NMSs and NEs is

called 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 uses

the 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 uses

DCC overhead bytes as physical DCN channels. The inband DCN uses Ethernet service

channels as physical DCN channels.

6.2 DCN Management

Reliable network management ensures proper running of a network, and therefore

transmission of network management data becomes very critical. The data communication

network (DCN) is a network management data communication channel, with which users can

remotely manage and maintain NEs.

Table 6-1 lists the DCN solutions that the OptiX OSN 500 supports.
