1 Managing WDM Protection Subnets

About This Chapter

A protection subnet has a structure of providing complete self-protection functions. The purposeof managing protection subnets is to configure and display network protection, for example,browsing, deleting, modifying and searching for protection subnets, managing isolated nodes.

1.1 Basic ConceptsAccording to the layered structure of transport network, protection subnet, belonging to thenetwork layer, refers to a network structure that has a comprehensive self-protection function.The protection subnet is a network unit of composing the optical transport network. To have agood understanding of the protection subnet, you need to learn some basic concepts of thenetwork layer.

1.1 Basic ConceptsAccording to the layered structure of transport network, protection subnet, belonging to thenetwork layer, refers to a network structure that has a comprehensive self-protection function.The protection subnet is a network unit of composing the optical transport network. To have agood understanding of the protection subnet, you need to learn some basic concepts of thenetwork layer.

1.1.1 Protection SubnetA protection subnet refers to a network architecture that has a comprehensive self-protectionfunction. It is a network that composes the optical transmission network.

1.1.2 Isolated NodeAn isolated node is not equal to an isolated NE. An isolated node refers to a special logicalsystem that is independent from any protection subnet. An isolated node does not belong to anyprotection subnet.

1.1.1 Protection SubnetA protection subnet refers to a network architecture that has a comprehensive self-protectionfunction. It is a network that composes the optical transmission network.

In the U2000, a protection subnet is a network level concept. NEs and fiber connections are thebasic elements required to construct a protection subnet. You should create NEs, perform basicconfigurations for them, and then properly create fiber connections between the NEs. You shouldhave access to sufficient resources to create a protection subnet.

1.1.2 Isolated NodeAn isolated node is not equal to an isolated NE. An isolated node refers to a special logicalsystem that is independent from any protection subnet. An isolated node does not belong to anyprotection subnet.

An isolated node is a node that is configured at NEs but cannot or does not compose a protectionsubnet with other nodes. Currently, the WDM equipment supports the 1:N optical path protectionsubnet and the ODUk SPRing protection subnet. The network node that is configured with the1:N optical path protection group or the ODUk SPRing protection group but does not belong toany protection subnet is an isolated node.

An isolated node should not exist in a transmission network that runs normally. The reason forthe existence of any isolated nodes can be as follows:

l The configuration is incorrect at the NE side.

l The fiber that should be connected to the node is not created on the U2000.

1.2 Searching for Protection SubnetsBy searching for a protection subnet, the configured protection attributes at the NE layer on theU2000 are synchronized to the network layer on the U2000 to create protection subnetsautomatically.

2 End-to-End WDM Management

About This Chapter

You can configure WDM services using the trail management function.

PrerequisiteThe trail management license must be provided for the U2000.

2.1 Managing WDM TrailsThis section describes how to manage end-to-end WDM services based on the trail managementfunction of the U2000.

2.2 Configuring Optical Layer Multipath ProtectionThe optical layer multipath protection can fully utilize the existing idle line resources of thenetwork. Through the optical cross-connections of the WSS boards, this protection offersautomatic and flexible selection of the protection paths in the protection switching.

2.3 Configuring EAPEThe U2000 supports configuring the enhanced automatic power equalization (EAPE) for a trail.By adjusting the optical power of a WDM trail, the EAPE can reduce or even eliminate bit errorsof services on the trail.

2.4 Managing Alarms on WDM TrailsYou can use the U2000 function of end-to-end trail management to manage the alarms generatedon WDM trails at the network layer.

2.5 Managing the Performance of WDM TrailsYou can use the network layer function of the U2000 to perform end-to-end performancemanagement on WDM trails.

2.6 Configuring Board ParametersWhen configuring WDM services, you need to configure different boards in the network. Thevarious types of boards and the procedure for configuring the board parameters are describedhere.

2.1 Managing WDM TrailsThis section describes how to manage end-to-end WDM services based on the trail managementfunction of the U2000.

PrerequisiteA U2000 user can manage all the trails that the user creates. To manage a trail that is created byanother U2000 user, a U2000 user must meet any of the following conditions:l The U2000 user belongs to the Administrators user group.l The right to manage the required trail is allocated to the U2000 user.

2.1.1 Configuration Task FlowA configuration task flow describes the operation tasks that manage an WDM network by usingthe end-to-end function of the U2000. In addition, the relationships between the operation tasksare described.

2.1.2 Basic ConceptsThis section describes the basic concepts of the WDM end-to-end management.

2.1.3 Creating WDM Trails by Trail SearchAfter a new network is set up or services are configured on a per-NE basis, you need to performan WDM trail search so that you can manage configured services by using the trail managementfunction.

2.1.4 Configuring WDM TrailsAfter searching out the relevant trail information on the U2000, you can create OCh, ODUk orclient trails by specifying the sources and sinks of the trails.

2.1.5 Creating a Platinum ServiceIn a platinum service group, the WDM trails do not pass through the same NE, fiber or fiber/cable pipe, so that the risk that multiple trails are interrupted is lowered.

2.1.6 Binding a Platinum Service GroupYou can bind a trail or trails when you need to add an existing trail to a platinum service groupor bind existing trails as a platinum service group.

2.1.7 Service Authorization ManagementIf there are multiple service trails maintained by different operators, they may care about onlythe trails in their own responsibility but ignore the other services. Service authorization can filterthe information not in concern of an operator, who then views and manages only the trails in theresponsibility. In this manner, the management and maintenance efficiency is improved.

2.1.8 Viewing WDM TrailsThis section describes how to view the connection relation of all boards on a WDM NE.

2.1.9 Maintaining WDM TrailsThe end-to-end trails are carriers of services of the customers. In the routine maintenance, theadministrator and maintainer must find out the status of the trails to ensure that all the servicesare transmitted correctly.

2.1.10 Modifying WDM TrailsDue to service requirements, sometimes, you need to modify the configuration of a WDM trail.U2000 supports manually modifying the source and sink of an exisiting WDM trail and the trailnames in batches, instead of creating WDM trails. This greatly simplifies the operations.

NOTE

l When you create a Client or an ODUk trail whose source or sink is an NG WDM NE, you need to setthe working mode of the card, and service mode and service type of the port. For details, see 2.6Configuring Board Parameters.

l When you create a Client or an ODUk trail in a network that consists of NG WDM NEs, you can createthe trail on an OCh server trail directly. Specifically, cross-layer creation is supported and the U2000can create mid-layer server trails automatically.

In the landscape orientation of the configuration flow diagram, the main phases of managing anWDM network by using the end-to-end function of the U2000 are shown, that is, configuringand maintaining a trail. All these functions require the corresponding license that provides theend-to-end management function.

The portrait orientation of the flow chart shows the relations between operation tasks in eachphase.

2.1.2 Basic ConceptsThis section describes the basic concepts of the WDM end-to-end management.

2.1.2.1 WDM TrailThe concept, type and relevant information about trails are described here.

2.1.2.2 Conflict TrailIf a trail exists on the U2000, but the cross-connection that forms the trail does not exist at theNE layer, this trail is a conflict trail.

2.1.2.3 Trail Creation MethodThe U2000 provides multiple methods for creating trails to meet different operation habits ofusers and requirements of different service scenarios.

2.1.2.4 Process for Creating a TrailThe trail creation process describes a series of procedures before a trail is generated on theU2000. The detailed process varies with the creation method.

2.1.2.5 Platinum Service GroupThe platinum service group is the combination of multiple WDM trails. Any two trails in thegroup do not pass through the same NE, fiber, or fiber/cable pipe. In this way, services are nothardly interrupted.

2.1.2.1 WDM TrailThe concept, type and relevant information about trails are described here.

The U2000 enables you to create, search, view, join, split, and delete WDM trails. In addition,the U2000 provides the signal flow diagram that visually displays the signal flow and thetransmission media layer route of trails. This facilitates operations and improves the maintenanceefficiency.

Currently the U2000 provides the following OTN trail modules that comply with ITU-T G.872:l Client traill ODUk trail: optical channel data unit (ODUk) traill OTUk trail: optical channel transport (OTUk) unit traill OCh trail: optical channel traill OMS trail: optical multiplexing section traill OTS trail: optical transmission section traill OSC trail: optical supervisory channel (OSC) trail

NOTE

l The first six types are related to services, and the OSC trail is related to supervisory signals.

l The OTS trail cannot be deleted from the U2000. You must delete the fiber connection before deletingthe OTS trail.

l The rate level varies with the value of "k" in ODUk/OTUk. For details, see Table 2-1. ODU5G/OTU5Gis a level customized by Huawei.

Inverse Multiplexing TrailThe rate of the client layer of an inverse multiplexing trail is greater than the rate of the serverlayer. Hence, an inverse multiplexing client trail needs multiple trails to serve as its server layer.Currently, you can only search for an inverse multiplexing trail, but you cannot create an end-to-end inverse multiplexing trail.

An inverse multiplexing client trail can take an ODU1 or ODU2 trail as the server trail. That is,an inverse multiplexing client trail cannot take ODU1 and ODU2 trails as the server trails at thesame time.

40G inverse multiplexing trail modelThe transmission rate of a single wavelength is 40G, but a single wavelength cannot used forlong-distance transmission due to an optical layer index (such as dispersion) restriction. In a40G inverse multiplexing transmission scheme, a 40G signal is converted to four 10G ODU2signals, each of which uses one wavelength. This is equal to four 10G signals on the line sideand lowers the optical layer index requirement.

Figure 2-6 shows the inverse multiplexing trail model of the TSXL card. You cannotdynamically adjust the bandwidth of STM-256 or OC768 services whose rate is 40G. Hence,you can search for a client trail only after you configure four ODU2 trails. If you configure onlyone, two or three ODU2 trails, services are unavailable and you fail to search for the client trail.




Issue 02 (2010-09-24)

Figure 2-6 40G inverse multiplexing trail

10G inverse multiplexing trail modelThe TDX card is a 10G inverse multiplexing tributary card that has two individual transmissionpaths. Each path inversely multiplexes a 10G service to multiple ODU1 signals, which are cross-connected to a line card for transmission. The 10G service uses any or all of the four ODU1signals according to bandwidth status. When the 10G service does not use all of the four ODU1signals, the 10G service share an ODU2 trail with other ODU1 signals. This saves line resources.

Figure 2-7 shows the inverse multiplexing trail model of the IP3 port on the TDX card. A 10Gservice is an Ethernet service for which you can dynamically adjust bandwidth. The server layerallows one, two, three or four ODU1 trails. Hence, the client trail that you search out is ofdifferent rate levels.

2.1.2.2 Conflict Trail

If a trail exists on the U2000, but the cross-connection that forms the trail does not exist at theNE layer, this trail is a conflict trail.

Cause

A trail consists of a single station cross-connection at the NE layer. If the configuration data atthe NE layer changes and a complete trail cannot be formed at the network layer, the trail thatexists on the U2000 is a conflict trail, and the corresponding cross-connection at the NE layerbecomes a discrete service.

l Adding a fiber leads to trail extension.

Assume that a trail is NE A-> NE B. Create a fiber from NE B to NE C, and create a serviceon NE C. As a result, the trail is extended as NE A->NE C. The trail NE A-> NE B thatexists on the U2000 becomes a conflict trail. See Figure 2-8.

Figure 2-8 A conflict trail generated because a fiber is added

NE A NE B NE C

l The single station cross-connection is lost.




Issue 02 (2010-09-24)

The original trail is NE A-> NE C. The cross-connection of the trail on NE B is deleted.On the U2000, the original trail of NE A-> NE C becomes a conflict trail and services onNE A and NE C become discrete services. See Figure 2-9.

NE 1 and NE 2 comprises a 1+1 linear protection and the original trail is NE 1-> NE 2. Ifcross-connection D of NE 2 is deleted, the original trail of NE 1-> NE 2 becomes a conflicttrail. See Figure 2-10.

Handling MethodDuring trail search, if the U2000 searches out a conflict trail, the U2000 stops the searching andasks you to confirm the conflict trail. There are the following two handling methods:l Stop searching.

If you fail to verify that the conflict trail is correct, you can choose to stop searching. Theconflict trail remains, but the U2000 does not generate a new trail.

l Continue to search.The system deletes the conflict trail from the network layer. This operation does not deletethe cross-connection on a per-NE basis, and does not affect services on the NE.

NOTE

After the conflict trail is deleted, its customized information, including the trail name, remarks, ispermanently lost and cannot be restored.

2.1.2.3 Trail Creation MethodThe U2000 provides multiple methods for creating trails to meet different operation habits ofusers and requirements of different service scenarios.



2-11

To successfully create a trail on the U2000, the following prerequisites must be met:l All the NEs that the trail passes through must have enough idle resources.l The data on the U2000 must be consistent with the data on the NE.l The fibers on the U2000 are correctly connected.

Table 2-2 shows the methods, features, and application scenarios of the trail creation.

Table 2-2 Comparison of methods for creating trails

Trail Creation Method Feature Application Scenario

Creating trails by trail search On a per-NE basis, configureall nodes that a service passesthrough. Then, by using thenetwork-layer trail searchfunction, combine cross-connections of each node toform end-to-end trails.

This method is applicable tothe scenario that the service isalready configured on a per-NE basis.This method requires bettertechnical knowledge ofusers. During the search,users may need to handleconflict trails and discreteservices.

Creating trails in theautomatic mode

l The service is configureddirectly at the networklayer. After the activationof the trail, the U2000deliver the cross-connections related to thetrail to all NEs involved.

l The route can becomputed automatically.

l If multiple routes existbetween the selectedsource and sink, you canset the compulsory link,the prohibited node toselect a route.

This method is applicable tothe creation of multi-layerOTN trails and a majority ofnormal trails.

Trail Creation Method Feature Application Scenario

Creating trails by trailreplication

l The service is configureddirectly at the networklayer. After the activationof the trail, the U2000deliver the cross-connections related to thetrail to all NEs involved.

l The route can becomputed automatically.

l You can only use theexsiting trail on theU2000 as a template andcreate the trails with thesame route in batches.

This method is applicable tothe batch creation of trailswith the same route, that is,the trails share the samesource, sink, and server trailwith the original trail.

2.1.2.4 Process for Creating a TrailThe trail creation process describes a series of procedures before a trail is generated on theU2000. The detailed process varies with the creation method.

2.1.2.5 Platinum Service GroupThe platinum service group is the combination of multiple WDM trails. Any two trails in thegroup do not pass through the same NE, fiber, or fiber/cable pipe. In this way, services are nothardly interrupted.

As shown in Figure 2-13, a bidirectional service exists between Router1 and Router2 and thisservice is displayed as trail A between NE1 and NE2 in the management scope of the U2000.To protect the service, another bidirectional trail needs to be added between the two routers andthis trail is displayed as trail B between NE3 and NE4 in the management scope of the U2000.When you create trail B, trail A is considered as a reference trail so that the two trails do not



2-15

pass through the same NE, fiber, or fiber/cable pipe. In this way, the risk that the two trails areinterrupted at the same time is lowered. Therefore, trail A and trail B form a platinum servicegroup.

Figure 2-13 Platinum service group

The platinum service group must meet the requirements as follows:

l A platinum service group contains a minimum of two trails.

l The trails cannot pass through the same NEs.

l The trails cannot pass through the same fiber.

l The trails cannot pass through the same fiber/cable pipes.

NOTEThe preceding constraints do not apply to a trail under protection. For example, the protection trails fortwo SNCP services travel along the same fiber/cable pipe. The platinum service group that the twoprotection trails belong to is Normal. In this case, a downgrade alarm does not occur.

When a third trail needs to be added into the platinum service group, you only need to specifythe existing trail A or trail B as the reference trail and then the U2000 automatically searchesout the two existing trails and groups the three trails.

NOTE

You can also bind the existing trails to generate a platinum service group.

As shown in Figure 2-13, when the platinum service group is no longer required, you can removetrail B from the platinum service group instead of deleting trail B. In this way, trail A and trailB are independent of each other and their routes are not mutually constrained. If rerouting occursor the route is modified, the two trails may pass through the same NE, fiber, and fiber/cable pipe.

When you create trails, different trails cannot fully comply with the requirements of the platinumservices due to insufficient resources and then you can create downgraded platinum services.As shown in Figure 2-14, trail A and trail B pass through NE5 and thus you can create only adowngraded platinum service group. A downgraded platinum service group cannot provide theexpected protection of a platinum service group. For example, when NE5 is faulty, theconnection between Router1 and Router2 is interrupted. To make the service group fully complywith the requirements of the platinum service, you can change the route of trail B to the routeof trail C between NE3 and NE4, when resources are sufficient.




Issue 02 (2010-09-24)

Figure 2-14 Downgraded platinum service group

A platinum service group contains multiple trails. Therefore, the service is not interrupted unlessall trails are interrupted. After detecting the interruption of a certain trail, the U2000 checkswhether other trails in the platinum service group are interrupted. If a complete trail exists, theseverity of the service interruption alarm is reduced to a lower level.

When the platinum service group does not meet the requirements due to a certain cause, theplatinum service group is in the downgraded state and the U2000 reports an alarm about thedowngrade of the platinum service.

2.1.3 Creating WDM Trails by Trail SearchAfter a new network is set up or services are configured on a per-NE basis, you need to performan WDM trail search so that you can manage configured services by using the trail managementfunction.

2.1.3.1 Searching for WDM TrailsAfter you create fibers and configure services for WDM equipment on the U2000, the trailinformation does not exist in the network layer of the U2000. To manage WDM trails, you needto search for the data of cross-connections and fiber connections over the network to generateend-to-end WDM trails at the network layer of the U2000.

2.1.3.2 Viewing Discrete ServicesIf some cross-connections on an NE cannot form trails at the network layer and are isolated onthe NE, these cross-connections are called discrete services. By using the U2000, you can viewthe details of a discrete service and the signal flow diagram of the trail where the discrete serviceis transmitted, and analyze the cause of the discrete service. This improves the maintainabilityof the discrete services of the U2000.

2.1.3.3 Activating and Deactivating Discrete ServicesIf certain cross-connections on NEs cannot form network-layer trails but exist on NEs separately,these cross-connections are called discrete services. Deactivating discrete services deletes theNE cross-connections from NEs and saves the relevant data on the U2000 only. This operationhelps to release the occupied channels. On the contrary, activating discrete services deployscross-connections to NEs according to the data saved on the U2000.

2.1.3.4 Acknowledging or Unacknowledging Discrete ServicesIn this user interface, you can acknowledge discrete services and filter discrete services basedon their acknowledgment status.



2-17

2.1.3.5 Deleting Discrete ServicesDiscrete services occupy the cross-connections required by normal services. As a result, normalservices cannot be created. Therefore, you need to delete the discrete services that are not in use.

2.1.3.1 Searching for WDM TrailsAfter you create fibers and configure services for WDM equipment on the U2000, the trailinformation does not exist in the network layer of the U2000. To manage WDM trails, you needto search for the data of cross-connections and fiber connections over the network to generateend-to-end WDM trails at the network layer of the U2000.

Prerequisitel You must be an NM user with "network maintainer" authority or higher.l Fiber connections must be created correctly for the WDM equipment.

Contextl Among the five types of trails, only the OTS trail can be managed directly without being

searched, because the data is stored at the network layer when fibers are created.l The networking in which no fiber connection exists between cross-connections of the same

level is not supported.l The U2000 supports the ability to search for an unterminated trail.l The U2000 supports the ability to search for a WDM trail that has multiple sources and

sinks.l The U2000 supports the ability to restore the user-defined information. When you delete a

trail from the network layer of the U2000, the user-defined information of the trail is savedin the system. Hence, when you search for a trail that has the same source or sink anddirection as the deleted trail, you can restore the user-defined information.

l You can only search for an inverse multiplexing client trail.

Procedure

Step 1 Choose Service > WDM Trail > Search for WDM Trail from the Main Menu.

Step 2 Under Advanced settings, set the search policies.




Issue 02 (2010-09-24)

NOTE

l In the mode of searching by subnet, the selected subnet range should be independent from thenetworking aspect. That is, no fiber connection exists between the selected subnet range and the areathat beyond the selected subnet range.

l If you select Hide optional trails, the third-party wavelength services can be searched out becausethey are not filtered out during verification.

Step 3 Click Next to begin to search for trails. The U2000 takes some time to return the results,depending on the number of services.

NOTE

l If there are cross-connections that are collisions and these cross-connections cannot form end to endtrails, the U2000 shows the conflicting trails after you perform the search operation.

l The principles of verifying a conflict trail are as follows: The networking changes. The trail may causeinterruption of service flow. For example, the key information of the trail, including deleting a cross-connection or fiber, is verified.

Step 4 Optional: Click Next to view the conflicting trail information. Select the trail to set the trailmanagement flag.

NOTE

Skip this step if the Automatically create trails after searching policy is selected in Step 2.

Step 5 Click Next to view all discrete services in the target network.

NOTE

If Step 4 is executed, the U2000 deletes trails that do not have the management flag from the network layer.This does not affect services of the actual NE or the data of an individual NE on the U2000.

Step 6 After the search is complete, click Finish.

2.1.4 Configuring WDM TrailsAfter searching out the relevant trail information on the U2000, you can create OCh, ODUk orclient trails by specifying the sources and sinks of the trails.

2.1.4.1 Creating an OCh TrailThe U2000 supports creating OCh trails in an end-to-end mode. After you specify the sourceand sink of a service, the U2000 can generate an OCh trail based on the searched server trail.The WDM trail creation feature simplifies the service configuration procedure and ensuresproper operation. In addition, you can groom and deploy services in a flexible manner inapplication scenarios (deployment or expansion).Before creating an EAPE pair, you should




Issue 02 (2010-09-24)

create OCh trails. The EAPE function uses OCh trails to identify EAPE pairs. In the case of theequipment with the dynamic optical cross-connection boards, you can create OCh trails manuallyby using the trail management function of the U2000.

2.1.4.2 Creating an ODUk TrailThe U2000 supports creating ODUk trails in an end-to-end mode. After you specify the sourceand the sink of a service, the U2000 automatically searches for the server trail and creates theODUk trail. The WDM trail creation feature simplifies the service configuration procedure andensures proper operation. In addition, you can groom and deploy services in a flexible mannerin application scenarios such as deployment or expansion.

2.1.4.3 Creating Client TrailsThe U2000 supports creating client trails in an end-to-end mode. After you specify the sourceand sink of a service, the U2000 generates a client trail based on the searched or created servertrail. The WDM trail creation feature simplifies the service configuration procedure and ensuresproper operation. In addition, you can groom and deploy services in a flexible manner inapplication scenarios such as deployment or expansion.

2.1.4.4 Creating a Mono Nodal TrailThe trails created on the same NE are called mono nodal trails. A mono nodal trail is createdbased on inter-card cross-connections. If the inter-card cross-connection is not supported, a mononodal trail is created based on fibers.

2.1.4.5 Creating a Multi-Layer OTN TrailWhen you create a Client trail or an ODUk trail for the NG WDM, an intermediate server trailis automatically created at the OCh server layer without creating the trail at each layer. Thissimplifies the operations.

2.1.4.1 Creating an OCh TrailThe U2000 supports creating OCh trails in an end-to-end mode. After you specify the sourceand sink of a service, the U2000 can generate an OCh trail based on the searched server trail.The WDM trail creation feature simplifies the service configuration procedure and ensuresproper operation. In addition, you can groom and deploy services in a flexible manner inapplication scenarios (deployment or expansion).Before creating an EAPE pair, you shouldcreate OCh trails. The EAPE function uses OCh trails to identify EAPE pairs. In the case of theequipment with the dynamic optical cross-connection boards, you can create OCh trails manuallyby using the trail management function of the U2000.

Prerequisitel You must be an NM user with "network operator" authority or higher.l The OMS server trail must be searched out.

ContextThe U2000 supports the function of creating a third-party wavelength service. A third-partywavelength service is the OCh trail whose source or sink port is located on the multiplexing anddemultiplexing card or the add/drop multiplexing card, or whose source and sink ports are locatedon such cards.

The U2000 does not support the ability to reuse discrete cross-connections.

The source and sink of an OCh trail are the ports at the line side of the OTU boards. The boardsthat the trail passes should support dynamic optical cross-connection or should contain static

optical cross-connection. The boards that support the dynamic optical cross-connection areclassified by equipment domain as follows:l For the OptiX BWS 1600G and the OptiX BWS 1600A: WSM9, WSD9, WSM5, WSD5

and RMU9.l For the OptiX Metro 6100V1E: WSM9, WSD9, RMU9, and WSMD4.l For the OptiX OSN 3800/6800/8800 I/8800 II and OptiX OSN 3800A/6800A/8800 I(NA)/

8800 II(NA): WSM9, WSD9, RMU9, ROAM, WSMD4, 11RDU9, 11WSMD2, 12WSM9,12WSD9, 13WSM9, 13WSD9, RDU6, WSM6.

NOTE

l In the WDM service configuration window, you can view the resource allocation of the entire network inan intuitive manner. When you create a service, available resources are automatically filtered and displayedin the topology view. The available resources can be the server links of the OTS level or higher levelsbetween NEs.

l When you create a trail, Auto-Calculation is selected by default. Route calculation is triggered when youspecify the source, sink, or route constraints, or configure protection. If the route calculation fails, an errormessage is displayed indicating the failure causes.

l If you clear the selection of Auto-Calculation, routes are not automatically calculated when you create atrail. You can click to Calculate Route check the correctness of a route.

2-25

TIP

l During the selection of source or sink in the NE Panel, when you move the cursor to a board, thewavelength information of the board port is displayed.

l By default, if you already select one end (source or sink) of a trail and open the NE Panel to selectanother end, the U2000 uses the board and port that have the same band and wavelength with priority.

l After you select the Enable third-party wavelength service port check box in the lower portion ofthe window, you can create a trail whose source or sink is located on the multiplexing anddemultiplexing card (for example, M40 and D40) or the add/drop multiplexing card (for example, MR2and WSM9), or whose source and sink ports are located on such cards. This trail is a third-partywavelength service.

NOTE

l By default, the selected wavelength frequency is the current wavelength frequency of a (source) sink port.You can select another proper wavelength frequency to meet the actual requirements.

l After the wavelength frequency for a source (sink) port is selected, the same wavelength frequency is selectedfirst for the corresponding sink (source) port. If the same wavelength frequency is not available for thecorresponding sink (source) port, the current wavelength frequency of the selected sink (source) port isselected by default.

2.1.4.2 Creating an ODUk Trail

The U2000 supports creating ODUk trails in an end-to-end mode. After you specify the sourceand the sink of a service, the U2000 automatically searches for the server trail and creates theODUk trail. The WDM trail creation feature simplifies the service configuration procedure andensures proper operation. In addition, you can groom and deploy services in a flexible mannerin application scenarios such as deployment or expansion.


l The OTU1 ODU1, ODU2, ODU3 or OTU2 server trail must be searched out.



2-27

l If the source or sink is the TOM or 12LQMS card, you must set the working mode of thecard first. For details, see 2.6.1 Configuring the Working Mode of the Board.

ContextThe configuration principles are as follows:l The source and sink of an ODUk (k = 0, 1, 2, 3, 5G) trail are LP ports of the TDG, TQM,

or TQS cards. The source and sink of an ODU0 trail are the LP ports of the tributary cards,such as the 52TOM cards.

l The line cards that support the grooming of ODU0 services are as follows: 52NS3, 52NQ2,52ND2, and 52NS2.

l The cards support the grooming of ODU0 services only in the synchronous mode. Thecards, however, do not support the grooming of ODU0 services in the asynchronous mode.

NOTE

In the synchronous mode, the cards (including tributary and line cards) that support the grooming ofODU0 services work with synchronous cross-connect cards. The cross-connect card can be the52XCH cards.

l Only ODU0, ODU1 and ODU2 trails can be created. ODU5G and ODU3 trails cannot becreated, but can be searched.

l If no cross-connect card (for example, XCS card) is available, the tributary card and linecard must be installed in paired slots of the same subrack.

l During the installation of cross-connect card (for example, XCS card), the tributary cardand line card must be installed on the same subrack.

l An ODU1 trail cannot be created on an OTU1 server trail formed by the networking of theTQS cards.

l Currently, two types of cards support the inverse multiplexing trail. The TSXL cardsupports the inverse multiplexing of the 40 Gbit/s service and the TDX card supports theinverse multiplexing of the 10 Gbit/s service

l The U2000 supports the ability to reuse discrete cross-connections.l The U2000 does not support the ability to create a trail whose source and sink use the same

subrack.l The U2000 does not support the ability to create a trail that is terminated at one end.

An example of the ODUk networking scenario is as follows:

2.1.5 Creating a Platinum ServiceIn a platinum service group, the WDM trails do not pass through the same NE, fiber or fiber/cable pipe, so that the risk that multiple trails are interrupted is lowered.


l The U2000 license that is used must support platinum services.

l Only the Client and ODUk platinum services can be created.

l The levels of the trails in a platinum service group must be consistent.

Context

The procedures of creating a platinum trail are almost the same as the procedures of creating anon-platinum service, that is, normal service. The only difference is that you need to select areference trail for a platinum service. If a reference trail is selected, a platinum service group iscreated at the same time. Otherwise, a non-platinum service (normal service) is created.

During the creation of a platinum service, if a reference trail is selected, the U2000 automaticallyfilters out the NE, fiber, and fiber/cable pipe that the reference trail passes through to calculatea new route. If this reference trail already belongs to a certain platinum service group, theU2000 also considers other trails in the platinum service group as reference trails to calculate anew route.

If the U2000 cannot calculate a route after filtering out the NE, fiber, and fiber/cable pipe thatthe reference trail passes through, the U2000 reduces the restrictions. Then, the U2000 calculatesa relatively appropriate route that passes through the preceding NE, fiber, or fiber/cable pipe tocontinue the creation. Therefore, a downgraded platinum service group is created.

Procedure

Step 1 Create the trail in the platinum service group according to the procedures of creating a non-platinum service.

By default, the WDM Trail Management window does not display the Platinum Service Group ID andPlatinum Service Group Status parameters. You can display these two parameters by right-clicking thetable head and choosing Platinum Service Group ID and Platinum Service Group Status,

The Platinum Service Group Status field can refresh the status of each trail in the service group in realtime.

l Normal indicates that the trail is a platinum service.

l Degrade indicates that the trail is a degraded platinum service.

l - indicates that the trail is not a platinum service.

The system automatically allocates Platinum Service Group ID incrementally. The trails with the sameID belong to the same platinum service group.


2.1.6 Binding a Platinum Service GroupYou can bind a trail or trails when you need to add an existing trail to a platinum service groupor bind existing trails as a platinum service group.



l Only the Client trails or ODUk trails can be bound.

l The levels of the trails to be bound must be the same.

l One trail cannot be bound to multiple platinum groups.

Context

The platinum service group can be bound in the following two scenarios:

l A platinum service group already exists. One or more non-platinum services need to beadded.

l Bind multiple non-platinum services to a platinum service group.




Issue 02 (2010-09-24)

In the preceding two scenarios, the levels of the trails must be the same. That is, in the firstscenario, the level of the trail to be added must be the same as the platinum service group. In thesecond scenario, the levels of all trails must be the same.

After the binding, the U2000 automatically checks whether the trails in the platinum servicegroup meet the requirements.

Procedure

Step 1 Choose Service > WDM Trail > Manage WDM Trail from the main menu.

l Normal indicates that the trail is a platinum service.

l Degrade indicates that the trail is a degraded platinum service.

l - indicates that the trail is not a platinum service.

The system automatically allocates Platinum Service Group ID incrementally. The trails with the sameID belong to the same platinum service group.

2.1.7 Service Authorization ManagementIf there are multiple service trails maintained by different operators, they may care about onlythe trails in their own responsibility but ignore the other services. Service authorization can filterthe information not in concern of an operator, who then views and manages only the trails in theresponsibility. In this manner, the management and maintenance efficiency is improved.

Figure 2-15 shows four service trails. Trails 1-2 are maintained by operator A and trails 3-4 aremaintained by operator B. By means of service authorization, operator A can maintain only trails1-2 and cannot maintain trails 3-4 on the U2000. Similarly, operator B cannot maintain trails1-2.

Issue 02 (2010-09-24)


l The trail is not locked.

Context

The procedures of modifying a trail in a platinum service group are almost the same as theprocedures of modifying a non-platinum service, that is normal service. The differences aredescribed as follows:

l When a trail in the platinum service group is modified, the U2000 automatically considersother trails in the platinum service group as reference trails. Therefore, when calculatingthe route, the U2000 automatically filters out the available resources of the fibers in thefiber/cable pipe that the reference trails pass through.

l When the trail in the platinum service group is modified, the U2000 checks whether thetrails in the platinum service group meet the requirements of the platinum service.

Procedure

Step 1 Modify the trail in the platinum service group according to the procedures of modifying the non-platinum service. For details, see 2.1.10.1 Changing the Source, Sink, and Route of a WDMTrail.

2.1.11 Deleting a WDM TrailThe operation deletes the WDM trails from the network layer or from the NE layer. You needto delete the trails if the network will be adjusted or rebuilt.

Prerequisitel You must be an NM user with "network operator" authority or higher.l The trail is not the OTS trail.l The trail must have the highest priority.l The trails that contain dynamic cross-connections must be deactivated before deleted. Other

trails can be directly deleted.

ContextA WDM trail can be deleted from the network side or the NE side.l If a trail is deleted from the network side, only the WDM trail at the network layer is deleted

on the U2000 side. The deleted trail is not delivered to the NE. Moreover, the service isnot affected. Generally, this method is adopted to synchronize the trail information on theU2000 side and the trail information at the network layer. After the trail is deleted from thenetwork layer, you can search for and find it again based on the service information at theNE layer.

l If a trail is deleted at the NE layer, the trail on the NE side is deleted accordingly. After thetrail is deleted, the service is interrupted. If the service configuration of the trail is incorrector needs to be modified, you can delete the trail at the NE layer and then create anothertrail.

l The U2000 supports the ability to delete a WDM trail and to delete a dynamic cross-connection related to the trail.

l The U2000 does not support the ability to delete the WDM trail that has a client trail.l The U2000 does not support the ability to delete an OTS trail.l Before you delete a WDM trail, the dynamic cross-connection related to the trail must be

Parameter PlanningOMS server trails need to be created before you create an OCh trail. Therefore, search for trailsbefore creating an OCh trail to ensure that the required OMS server trails exist.

NOTE

When creating OCh trails, ensure that the wavelength of an OTU card matches the wavelength of aconnected multiplexer or demultiplexer card.

l In the case of a static multiplexer or demultiplexer card, such as M40 and MR2, the wavelength ofthe OTU card must be the same as the wavelength of the port on the multiplexer or demultiplexercard that is connected to the OTU card.

l In the case of a dynamic multiplexer or demultiplexer card, such as WMS9 and RMU9, thewavelength of the OTU card must match the band of the multiplexer or demultiplexer card that isconnected to the OTU card.

l In the preceding example, cards WSM9 and WSD9 belong to even bands. Therefore, you need toselect even wavelengths for the wavelength of the NE2 card.

Parameter PlanningServer trails need to be created before you create an ODU1 trail. In the network provided in theexample, the server trails include OMS, OCh, ODUk, and OTUk trails. Among them, the OMStrail can be searched out directly and need not be created manually. Since the U2000 supportsthe cross-layer creation of trails, an ODU1 trail can be created on an OCh trail directly. Therefore,you need to create an OCh trail before creating an ODU1 trail.

Since the ODU1 trail is a dual fed and selective receiving service, a working route and aprotection route exist for the trail. Therefore, in addition to the creation of the ODU1 trail, youneed to create server trails for its working route and protection route, that is, OCh-trail-1 andOCh-trail-2.

NOTE

The ODU1 service has the working route, NE1->NE4, and the protection route, NE1->NE2->NE3->NE4.

Card Configuration

In this example, one 52TOM card and two 52NS2 cards are configured on both NE1 and NE4and two 52NS2 cards are configured on both NE2 and NE3.





Issue 02 (2010-09-24)


Service Signal FlowA bidirectional GE service with the subnetwork connection protection (SNCP) exists betweenNE1 and NE4. The working route is NE1->NE4 and the protection route is NE1->NE2->NE3->NE4.


Figure 2-42 GE service signal flow



2-93


Parameter Planning

If you create a GE service with the traditional method, you also need to create the server trailsfor the service. In the network provided in the example, the server trails include OMS, OCh,ODU2, and ODU1 trails. Among them, the OMS trails can be searched out directly and neednot be created manually. After you create an OCh trail, you can search out the OTUk trail bythe trail search.

Since the GE service is a dual fed and selective receiving service, a working route and a protectionroute exist for the service. Therefore, in addition to the creation of the GE service, you also needto create server trails for the working route and protection route. In the tables below, trail-1represents the server trail of the working route and trail-2, trail-3, trail-4 represents the servertrail of the protection route.

NOTEThe GE service has both the working route that is NE1->NE4 and the protection route that is NE1->NE2->NE3->NE4.

l The working route traverses the following OCh trail: OCh-trail-1.

l The protection route traverses the following OCh trails: OCh-trail-2 (that is, NE1->NE2), OCh-trail-3(that is, NE2->NE3), and OCh-trail-4 (that is, NE3->NE4).

Issue 02 (2010-09-24)

Parameter Planning

If you create a GE service with the cross-layer creation method, you can create the servicedirectly on an OCh link because the ODU2 and ODU1 server trails are generated automaticallyduring the creation of the GE service. In the network provided in the example, the server trailsinclude OTS, OMS, OCh, ODU2, and ODU1 trails. Among them, the OTS and OMS trails canbe searched out directly and need not be created manually. Hence, you only need to create anOCh trail and the GE service.

Since the GE service is a dual fed and selective receiving service, a working route and a protectionroute exist for the service. Therefore, in addition to the creation of the GE service, you also needto create server trails for the working route and protection route. In the tables below, trail-1represents the server trail of the working route and trail-2, trail-3, trail-4 represents the servertrail of the protection route.

NOTEThe GE service has both the working route that is NE1->NE4 and the protection route that is NE1->NE2->NE3->NE4.

l The working route traverses the following OCh trail: OCh-trail-1.

l The protection route traverses the following OCh trails: OCh-trail-2 (that is, NE1->NE2), OCh-trail-3(that is, NE2->NE3), and OCh-trail-4 (that is, NE3->NE4).

2.2 Configuring Optical Layer Multipath ProtectionThe optical layer multipath protection can fully utilize the existing idle line resources of thenetwork. Through the optical cross-connections of the WSS boards, this protection offersautomatic and flexible selection of the protection paths in the protection switching.

This topic describes the procedures for configuring the optical layer multipath protectionmanually, including information on how to create, delete the protection and modify parameters.

2.2.1 Configuring Optical Layer Multipath ProtectionAutomatically

This topic describes the procedures for configuring the optical layer multipath protectionautomatically, including information on how to create, delete the protection and modifyparameters.

2.2.1.1 Configuration PrincipleWhen configuring the optical layer multipath protection, you need to learn the followingprinciples to configure the protection properly.

2.2.1.2 Enabling the WSS Function on an NEBefore configuring the optical layer multipath protection, you need to enable the WSS functionon NEs that are used in this protection. In this manner, these NEs can gain information aboutthe topology networkwide through the discovery function for adjacent NEs. When a fiber cutoccurs in a path that carries services, the NEs can be on the rerouted path for the optical layermultipath protection.

2.2.1.3 Creating a Working Cross-Connection for an NEYou need to create cross-connections on a per-NE basis, which ensures that the working paththat carries services passes the WSS boards.

2.2.1.4 Searching for WDM TrailsAfter you set up fiber connections on NEs, the corresponding trail information cannot be foundat the network layer on the U2000. To implement the WDM trail management, you need toestablish the end-to-end WDM trails at the network layer on the U2000 by searching for thecross-connections and fiber connections in the network.

2.2.1.5 Creating Optical Layer Multipath Protection AutomaticallyBy using the function of creating the optical layer multipath protection for the OCh trailautomatically, the users need not learn the detailed route information about this protection. TheU2000 creates the optical cross-connections for the protection automatically in the WSS boardsaccording to the utilization of resources networkwide. Creating the optical layer multipathprotection automatically can simplify the configuration procedure and avoid incorrectoperations.

2.2.1.6 Modifying the Parameters of Optical Layer Multipath ProtectionFor the optical layer multipath protection that is created, you can query the working path andmodify the corresponding parameters on the U2000.

2.2.1.1 Configuration Principle

When configuring the optical layer multipath protection, you need to learn the followingprinciples to configure the protection properly.

The common principles for the configuration of the optical layer multipath protection are asfollows:

l Plan the wavelengths networkwide. Configure a unique wavelength for each service toprevent wavelength conflict in switching.

l Reserve wavelength resources for the protection when you plan the network.




Issue 02 (2010-09-24)

l The WSD+WSM networking is recommended, so that no wavelength conflict occurs inservices.

l The protection cannot be configured for the FOADM station and ROADM station of theDWC network.

l Configure the logical fiber connections that are consistent with the actual networking onthe U2000.

l When a fiber cut occurs in the working path, NEs find a protection path through rerouting.Meanwhile, the U2000 switches the services to the protection path. If a fiber cut occurs inthe protection path and the working path remains faulty, NEs will find another protectionpath through rerouting again.

l Create an OCh trail as the working path before creating the optical layer multipathprotection. It is recommended that you create the optical cross-connections on a per-NEbasis and form an OCh trail through the search function. If you create the optical cross-connections by trail, you need to plan the network first to ensure that the created trail passesthe WSS boards.

l You need not create the protection cross-connections within the WSS boards. The cross-connections of the route can be viewed on NEs only when the protection switching(rerouting) occurs.

2.2.1.2 Enabling the WSS Function on an NE

Before configuring the optical layer multipath protection, you need to enable the WSS functionon NEs that are used in this protection.

2.3 Configuring EAPEThe U2000 supports configuring the enhanced automatic power equalization (EAPE) for a trail.By adjusting the optical power of a WDM trail, the EAPE can reduce or even eliminate bit errorsof services on the trail.

2.3.1 EAPEThe U2000 provides the enhanced automatic power pre-equilibrium (EAPE) function. TheEAPE adjustment can be enabled to ensure that the receive-end signal quality of each channelmeets the preset requirement and that the services are available.

2.3.2 Creating an OCh TrailThe U2000 supports creating OCh trails in an end-to-end mode. After you specify the sourceand sink of a service, the U2000 can generate an OCh trail based on the searched server trail.The WDM trail creation feature simplifies the service configuration procedure and ensuresproper operation. In addition, you can groom and deploy services in a flexible manner in



2-137

application scenarios (deployment or expansion).Before creating an EAPE pair, you shouldcreate OCh trails. The EAPE function uses OCh trails to identify EAPE pairs. In the case of theequipment with the dynamic optical cross-connection boards, you can create OCh trails manuallyby using the trail management function of the U2000.

2.3.3 Creating EAPE ObjectsThe U2000 supports configuring the enhanced automatic power equalization (EAPE) for a trail.For a WDM service configured with the EAPE, the U2000 fine-tunes the optical power of thetransmit end according to signal quality detected by the receive end. This can improve the signalquality.

2.3.4 Querying EAPE ObjectsOn the U2000, you can query the enhanced automatic power equalization (EAPE) objects thatare already created on the trail and enable or disable the EAPE adjustment.

2.3.5 Starting EAPE AdjustmentIn the case of a WDM service configured with EAPE, when the OTU at the sink end detects thesignal degrade, an exceptional EAPE event is reported to and displayed on the U2000. This eventprompts the user to start EAPE adjustment so that the VOA at the source end finely tunes theoptical power at the transmit end. This can enhance the signal quality.

2.3.6 Deleting EAPE ObjectsWhen the EAPE function on the trail is not required, you can manually delete the EAPE.

2.3.1 EAPEThe U2000 provides the enhanced automatic power pre-equilibrium (EAPE) function. TheEAPE adjustment can be enabled to ensure that the receive-end signal quality of each channelmeets the preset requirement and that the services are available.

Function Description

In practice of WDM system operation, the optical power flatness of each channel, comparedwith that during deployment commissioning, greatly changes due to fiber condition variation.As a result, the quality of received signals does not meet the requirement. In this case, EAPEadjustment can be enabled to ensure that the receive-end signal quality of each channel meetsthe preset requirement and that the services are available.

Function Implementation

The procedure to implement the EAPE function is as follows:

1. During deployment commissioning, manually adjust the optical power of each channel toobtain signal quality that meet the requirement. This ensures that each channel normallyoperates.

2. During system operation, the OTU at the receive end detects the signal quality of eachchannel.

3. When the OTU at the receive end detects an alarm, if the optical power of the OTU at thereceive end does not cross the threshold, adjust the optical power attenuation ratio of thecorresponding channel according to the actual situation. This ensures that the receive-endsignal quality of each channel meets the preset requirement and that the services areavailable.




Issue 02 (2010-09-24)

Involved BoardsThe service board and the SCC board are jointly used to achieve the EAPE function. Thisfunction involves the following types of boards and ports:l OTU detection unit

– Detects the receive-end signal quality of each channel and reports any EAPE unbalanceevent detected.

– The boards that support this function include the OTUs and line boards with the FECfunction.

l Adjustment unit: It is the EAPE adjustment entity that adjusts the optical attenuation ofeach channel. The boards that support this function include ROAM, WSM9, WSD9,WSM5, WSD5, WSMD4, DWC, EDWC, V40, M40V, D40V, V48, VA2, VA1 and VA4.

l Received signal selection unit– The system locates the point to be adjusted according to the current protection state of

the OLP or DCP board.– The boards that support this function include the OLP and DCP.

l System control and communication unit– It is the system entity that carries out the EAPE function.– The boards that support this function include the SCC.

NOTE

For the EAPE function, EAPE protocol frames can be sent to each node as long as the physicalcommunication route is reachable. The EAPE protocol frames can be sent in modes such as the OSC andESC.

Networking ScenariosThe EAPE function can be applied in three typical scenarios.

EAPE application scenario 1 is with the basic configuration that only a trail with VOA unitexists. Figure 2-56 shows the networking diagram of this application mode. The figure illustratesonly the unidirectional EAPE pair.

Figure 2-56 Scenario of the single VOA unit that takes the common OTU as the source

EAPE application scenario 2 is applicable to the dual fed and selective receiving OTU board.Each of the two receive optical interfaces of the dual fed and selective receiving OTU has anFEC module. Two trails with VOA units exist. Hence, in this networking mode, you need toconfigure two EAPE pairs.Figure 2-57 shows the networking diagram of this application mode.The figure illustrates only the unidirectional EAPE pair.



2-139

Figure 2-57 Scenario of the dual VOA units that take the dual-fed and selective-receiving OTUsas the sources

EAPE application scenario 3 is applicable to the 5 Gbit/s, 10 Gbit/s and 40 Gbit/s OTUs. In thisnetworking mode, the intra-board 1+1 protection needs to be configured. Only one EAPE pairneeds to be configured. When the sink OTU detects an anomaly, the system locates the VOA tobe adjusted according to the current services operating channel. Figure 2-58 shows thenetworking diagram of this application mode. The figure considers the OLP board as an exampleto illustrate only the unidirectional EAPE pair.

Figure 2-58 Scenario of the dual VOA units with the OLP protection units

Configuration Principle

The EAPE configuration principles are as follows:

l When creating the EAPE, you must create the corresponding OCh trail firstly.

l Based on the basic application scenario, you just need to specify the source OTU, sink OTUand adjustment unit.

l When the OTU is jointly used with the OLP or DCP board for networking, besidesspecifying the source OTU and sink OTU, you also need to specify the OLP or DCP boardand the active and standby adjustment units. In this networking mode, the sink OLP or DCPboard and the sink OTU must be configured on one NE; the adjustment unit and the sourceOTU must be configured on another NE.

l The FEC type of the source and sink OTU must keep consistent. After EAPE is configured,the FEC working mode of the OTU must not be changed; the FEC function of the OTUmust be enabled.

l EAPE requires that the monitored path is a complete end-to-end wavelength without anyintermediate add or drop wavelength.




Issue 02 (2010-09-24)

l An OCh trail with regenerating stations equals to two independent wavelengths and thusneed be configured with two EAPE pairs.

l EAPE requires that the adjustment unit is configured in the transmit-end station and theOTU detection unit is configured in the receive-end station.

l An OCh trail with multiple sources and sinks does not support the EAPE function.l The uploading function is not supported, but the script importing and exporting function is

supported.l If the EAPE ID on the U2000 is inconsistent with that on the NE, you need to delete the

trail on the U2000 from the network layer, search for a new trail, and then query or createEAPE objects. In this way, you can obtain the EAPE objects with consistent data betweenthe U2000 and the NE.

l The adjustment board cannot be on the sink NE, and the selective receiving board cannotbe on the source NE.

l The FEC mode of the source OTU and sink OTU should be the same.

2.3.2 Creating an OCh TrailThe U2000 supports creating OCh trails in an end-to-end mode. After you specify the sourceand sink of a service, the U2000 can generate an OCh trail based on the searched server trail.The WDM trail creation feature simplifies the service configuration procedure and ensuresproper operation. In addition, you can groom and deploy services in a flexible manner inapplication scenarios (deployment or expansion).Before creating an EAPE pair, you shouldcreate OCh trails. The EAPE function uses OCh trails to identify EAPE pairs. In the case of theequipment with the dynamic optical cross-connection boards, you can create OCh trails manuallyby using the trail management function of the U2000.

Prerequisitel You must be an NM user with "network operator" authority or higher.l The OMS server trail must be searched out.

ContextThe U2000 supports the function of creating a third-party wavelength service. A third-partywavelength service is the OCh trail whose source or sink port is located on the multiplexing anddemultiplexing card or the add/drop multiplexing card, or whose source and sink ports are locatedon such cards.

The U2000 does not support the ability to reuse discrete cross-connections.

The source and sink of an OCh trail are the ports at the line side of the OTU boards. The boardsthat the trail passes should support dynamic optical cross-connection or should contain staticoptical cross-connection. The boards that support the dynamic optical cross-connection areclassified by equipment domain as follows:l For the OptiX BWS 1600G and the OptiX BWS 1600A: WSM9, WSD9, WSM5, WSD5

and RMU9.l For the OptiX Metro 6100V1E: WSM9, WSD9, RMU9, and WSMD4.l For the OptiX OSN 3800/6800/8800 I/8800 II and OptiX OSN 3800A/6800A/8800 I(NA)/

8800 II(NA): WSM9, WSD9, RMU9, ROAM, WSMD4, 11RDU9, 11WSMD2, 12WSM9,12WSD9, 13WSM9, 13WSD9, RDU6, WSM6.

2.3.3 Creating EAPE ObjectsThe U2000 supports configuring the enhanced automatic power equalization (EAPE) for a trail.For a WDM service configured with the EAPE, the U2000 fine-tunes the optical power of thetransmit end according to signal quality detected by the receive end. This can improve the signalquality.

Prerequisitel You must be an NM user with "network operator" authority or higher.l An OCh trail must be created or searched out.

Background Information

To create an EAPE pair correctly, the OCh trail must meet the following:

l The source and sink board must be the OTU boards.l The board with the VOA unit must be configured on the trail.l If the protection is configured on the trail, the selective receiving unit at the sink must be

the OLP or DCP. In addition, the board with the VOA unit need be configured on theprotection trail.

l EAPE requires that the adjustment unit is configured on the transmit-end station and theOTU detection unit is configured on the receive-end station.

l Source and sink OTU boards cannot be installed on the same NE.l The working and protection adjustment units can be configured in different slots on the

same NE.l When the corresponding EAPE pairs exist on an OCh trail, you cannot modify or deactivate

the trail.l In the case of the OCh path with the electrical REG, the OCh path is equivalent to two

independent wavelengths. Thus, you need configure two EAPE pairs on the OCh path.l EAPE can monitor only the trails on a complete end-to-end wavelength. Thus, no

wavelength can be added or dropped along the trail.

Procedure

Step 1 Choose Trail > WDM Trail Management from the Main Menu. Select filter criteria accordingto requirements.

2.6.1.2 Configuration Rules of the 52TOM board

This section describes the rules for configuring the 52TOM board.

The rules for configuring the 52TOM board are as follows:

l In non-cascading board working mode, the ports on the board can be set to different portworking modes.

l The OptiX OSN 8800 series does not support distributed cross-connection.

l In tributary-line mode, the ODU1 service does not support centralized cross-connection.

l The 52TOM board can groom a maximum of six Any services through the backplane. Inthe OptiX OSN 6800/3800, the 52TOM board can groom Any services on the oppositeboard but cannot groom Any services throughout the full-mesh network. Particularly, inthe OptiX OSN 3800, inter-board ODU1 cross-connections between the 52TOM and52NS2 boards, if required, should be configured in such a manner that the ClientLP3.1 porton the 52TOM board is cross-connected to the ODU1LP1.3 port on the 52NS2 board, theClientLP5.1 port on the 52TOM board is cross-connected to the ODU1LP1.2 port on the52NS2 board, and the rest may be deduced by analogy.

l The OptiX OSN 6800/3800 cannot groom the ODU0 service and thus does not support thefollowing port working mode application scenarios:

– Non-cascading ODU1 tributary mode application scenario 2 (OTU1->ODU1->ODU0)

– Non-cascading ODU1 tributary mode application scenario 3 (OTU1->ODU1->Any->ODU0)

l The OptiX OSN 8800 series does not support the following port working mode applicationscenario:

– Non-cascading ODU1 tributary mode application scenario 4 (OTU1->ODU1->Any->ODU0->ODU1)
