Planning the Optical-Path-Shared MSP

Capabilities of Supporting the Optical-Path-Shared MSP

When planning the optical-path-shared MSP for Huawei OptiX OSN 2500, first consider the
capabilities of supporting the optical-path-shared MSP.
In the case of the optical-path-shared MSP, one optical interface can be configured into two
MSP groups. Thus, multiple MSP rings can share the same fiber and optical interface.
The OptiX OSN 2500 supports the configuration of the optical-path-shared MSP.
l The SF16 and SL16 boards can process two sets of K bytes, which are located in the first
and fifth STM-1s. The SF16 and Huawei SL16 boards support configuring a single optical interface
into a maximum of two MSP rings.

Planning Principles

To rationally and effectively plan the optical-path-shared MSP protection, the planning
principles should be followed.

In normal situations, in the case of the optical-path-shared MSP, two low-rate line units share
the same high-rate line unit.

In the optical-path-shared MSP, two line STM-16 units at the same rate can share the same line unit.

When the optical-path-shared MSP is configured, on the protection ring, the optical interfaces

in two directions need not be configured into paired slots.

Huawei OptiX OSN 2500 Supporting Tasks of Software Loopback

Outloop
The SDH optical interface board, PDH electrical interface board, Ethernet interface board like Huawei EGS4  and ATM board all support outloop.

Inloop
The SDH optical interface board like Huawei SLD64, PDH electrical interface board, Ethernet interface board and ATM board all support inloop

Loopback at an SDH Interface
Prerequisites
You must be an NE user with "NE and network operator" authority or higher.
To test whether the interface module and external cables of a board are normal, you need to set
an outloop.
To test whether the cross-connect unit and service path of the equipment are normal, you need
to set an inloop.
Impact on Services
In the case of non-protection, the loopback may interrupt the services or the communication
signals.
Tools/Instruments
T2000
Procedure
Step 1 In the Main Topology of the T2000, select the NE to be looped back.
Step 2 Right-click the NE icon in the Main Topology and select NE Explorer.
Step 3 Select the board from the Object Tree and select Configuration > SDH Interface from the
Function Tree.
Step 4 Select By Function. Select Optical (Electrical) Interface Loopback.
Step 5 Select the port and select the loopback mode Inloop or Outloop.
Step 6 Click Apply. The confirm dialog box is displayed. Click OK.
Step 7 The Operation Result dialog box is displayed and indicates that the operation is successful.
Click Close.

Huawei OptiX OSN 2500 Review

Network Application

The OptiX OSN 2500 intelligent optical transmission system (hereinafter referred to as the Huawei OSN 2500) developed by Huawei is the next-generation intelligent optical transmission equipment.

The OptiX OSN 2500 integrates the following technologies to transmit voice and data services on the same platform with high efficiency:

• Synchronous digital hierarchy (SDH)
• Plesiochronous digital hierarchy (PDH)
• Ethernet
• RPR(Resilient Packet Ring)
• Asynchronous transfer mode (ATM)
• Storage area network (SAN)
• Wavelength division multiplexing (WDM)
• Digital data network (DDN)
• Automatically switched optical network (ASON)
• Microwave Technology

Appearance of the OptiX OSN 2500

The OptiX OSN 2500 is used at the access layer and the convergence layer of a metropolitan area network (MAN). The OptiX OSN 2500 can also be networked with the following equipment to optimize the investment for customers:

• OptiX OSN 9500
• OptiX OSN 7500
• OptiX OSN 3500
• OptiX OSN 3500 II
• OptiX OSN 2500 REG
• OptiX OSN 1500
• OptiX 2500+_{(Metro 3000)}
• OptiX 155/622H_{(Metro 1000)}

Network application of the OptiX OSN 2500

Networking Topology

The OptiX OSN 2500 supports topologies such as chain, ring, tangent rings, intersecting rings, ring with chain, dual node interconnection (DNI), hub, and mesh at the STM-1/STM-4/STM-16/ level.

The OptiX OSN 2500 supports the separate and hybrid configuration of the following types of NEs:

• Terminal multiplexer (TM)
• Add/drop multiplexer (ADM)
• Multiple add/drop multiplexer (MADM)
• The OptiX OSN 2500 can be interconnected with Huawei OSN, DWDM, and Metro equipment series, to provide a complete transmission network solution.

NOTE:

When the equipment is being interconnected, make sure that the K bytes to be received and transmitted are on the same path at both ends.

• The OptiX OSN 2500 can be used with another OptiX OSN equipment to provide a complete ASON solution. This solution covers all the layers including the backbone layer, the convergence layer, and the access layer.
• Through an SDH interface or a GE interface, the OptiX OSN 2500 can be interconnected with the WDM equipment.
• Through an SDH, PDH, Ethernet, ATM, or DDN interface, the OptiX OSN 2500 can be interconnected with the OptiX Metro equipment.
