The landscape orientation of the configuration flow chart shows the main phases of managing the WDM network by using the T2000. The phases include network deployment, service configuration, WDM feature configuration, network maintenance, and WDM ASON feature management. In the case of the service configuration, the end-to-end service configuration mode requires a license that supports the end-to-end WDM management, and the WDM ASON feature management requires a license that supports the WDM ASON feature. The WDM ASON feature is unique to the NG WDM. An NG WDM NE can use the WDM ASON feature management function only after the WDM ASON feature is enabled.

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

3 Configuring IP over DCC

About This Chapter This section describes the definition of the IP over DCC. It also respectively illustrates four communication modes between the NE and T2000.

3.1 Overview

This section describes the basic functions and features of IP over DCC.

3.2 Basic Operations

Describes the basic operation of configuring IP Over DCC on the T2000. Include the operation authority and precautions description.

3.3 Parameters

Describes the parameters involved in the IP Over DCC configuration on the T2000.

3.4 Application Example

This section describes three applications based on the three modes in which the T2000 communicates with the NE.

3.1 Overview This section describes the basic functions and features of IP over DCC.

The DCC is used to transmit the operation, administration, and maintenance (OAM) data between WDM equipment. The protocol stacks used by different vendors are not compatible with each other. Thus, extra overhead bytes or service resources must be allocated to transmit DCC data transparently in a network composed of multi-vendor products.

The IP over DCC meets most of the networking requirements in existing networks without occupying extra overhead bytes or service resources. The IP over DCC simplifies the network structure, saves network resources, and meets the networking requirements quickly.

The IP over DCC supports the following features:

Adopts the standard TCP/IP protocol, which makes it compatible with other vendor's equipment and simplifies the network management.

3 Configuring IP over DCC OptiX OSN 8800 I/6800/3800

Configuration Guide


Issue 21 (2009-08-10)

Adopts the forwarding function of the third layer in the protocol stack, which makes extra overheads or service paths unnecessary.

Brings flexible networking models. Brings simple upgrade modes and great compatibility. It is easy for IP over DCC to work

with new forwarding or multi-protocol features on the application layer.

IP over DCC support two remote accessing modes.

Gateway NE mode: The ECC protocol is used. For remote access, log in to the GNE that is connected to the computer. Then other NEs can be accessed through the NE ID. After the IP over DCC feature is added, this mode can still be used to access remote NEs.

Direct connection mode: The IP over DCC feature is used, and the remote NE can be connected directly through the IP address. You just need to enter the destination IP address in the login interface. For this mode, however, you need to add in advance the static route or default gateway in the network T2000 and the NE that needs to be accessed directly.

The router information of the NE can be queried on the following two user interfaces of the T2000:

Select the desired NE in the NE Explorer, and choose Communication > IP Protocol Stack Management from the Function Tree, and the IP router information of the NE can be queried.

Select the desired NE in the NE Explorer, and choose Communication > NE ECC Link Management from the Function Tree, and the ECC link information of the NE can be queried.

3.2 Basic Operations Describes the basic operation of configuring IP Over DCC on the T2000. Include the operation authority and precautions description.

For the related operations about creating the NE, refer to 4.2 Creating NEs.

3.2.1 Setting NE Communication Parameters

When configuring IP over DCC, you need to set the IP address, extended ID, gateway IP, and subnet mask of the NE.

3.2.2 Configuring Static Routing

If the NE adopts IP over DCC and direction communication connection mode, you need to configure a static route between the NM computer and the NE.

3.2.1 Setting NE Communication Parameters When configuring IP over DCC, you need to set the IP address, extended ID, gateway IP, and subnet mask of the NE.

Prerequisite You must be an NM user with "NE maintainer" authority or higher.



3-3

Precautions

The operation of modifying the NE communication parameters interrupts the communication and affects the services.

Procedure Step 1 Double-click the ONE icon on the Main Topology. The NE Panel tab is displayed.

Step 2 Right-click the NE icon and select NE Explorer.

Step 3 In the NE Explorer, click the NE and choose Communication > Communication Parameters from the Function Tree.

Step 4 Refer to Table 3-1 to set NE communication parameters according to the actual plan. Enter values in the IP address, Gateway IP, and Subnet Mask fields.

IP is the IP of the NE. Extended ID is the eight most significant bits in the 24 bits of the NE. It indicates different subnets. Gateway IP is different from IP. It is not the IP address of the NE. It is the IP address of the router

that is used to realize TCP/IP communication when the NE accesses the NM or NE in a remote end.

Step 5 Click Apply.

----End

3.2.2 Configuring Static Routing If the NE adopts IP over DCC and direction communication connection mode, you need to configure a static route between the NM computer and the NE.


Procedure Step 1 Double-click the ONE icon on the Main Topology. The NE Panel tab is displayed.

Step 2 Right-click the NE icon on the Main Topology, and then select NE Explorer.

Step 3 Select the desired NE from the object tree. Then choose Communication > IP Protocol Stack Management from the Function Tree.

Configuration Guide


Issue 21 (2009-08-10)

Destination Address: the IP address of the NE that requires communication Subnet Mask: the network mask code of the subnet where an NE resides Gateway IP: the IP address of the forwarding NE

Step 6 Click Apply.

----End

3.3 Parameters Describes the parameters involved in the IP Over DCC configuration on the T2000.

Table 3-1 lists the NE communication parameters.

Table 3-1 NE communication parameters

Field Description

IP The IP address of an NE. After the IP address is set manually, any ID address change will no longer affect the IP.

Extended ID

The eight most significant bits in the 24 bit of the NE, also called the subnet number, used to identify different subnets.

Gateway IP For NEs communicating with the T2000 through IP over DCC protocol, gateway IP is the IP address of the NE with routing function.

Subnet Mask

The network mask code of the subnet where an NE resides, used to identify the network segment where an NE resides.

NSAP Address

Includes domain address and NE ID. The domain address is editable, which can be a hexadecimal number that contains a maximum of 13 bytes. This parameter gives no contribution in the configuration of IP Over DCC.

3.4 Application Example This section describes three applications based on the three modes in which the T2000 communicates with the NE.

3.4.1 Application 1: In Gateway NE Mode

If the T2000 and the GNE connect to the same Ethernet (the T2000 and the GNE must be in the same subnet), and other NEs are accessed in the gateway NE mode, you need not to add any static routes.

3.4.2 Application 2: In Gateway NE Mode (by Default Gateway)

If the T2000 connects with the GNE through a router and other NEs are accessed in the gateway NE mode, you need to add a default gateway on the T2000 and on the GNE.

3.4.3 Application 3: In Direct Connection Mode (by Static Routes)



3-5

If the T2000 and the GNE connect to the same Ethernet and other NEs are accessed in the direct connection mode, you need to set on the T2000 the default gateway to the IP address of the NE that is directly connected to the T2000. In addition, you need to add the static route to the non-GNEs, with the forwarding address as the IP address of the GNE.

3.4.1 Application 1: In Gateway NE Mode If the T2000 and the GNE connect to the same Ethernet (the T2000 and the GNE must be in the same subnet), and other NEs are accessed in the gateway NE mode, you need not to add any static routes.

Background Information As shown in Figure 3-1, the T2000 with the IP address of 129.9.0.100 uses the nearby NE1 as the GNE to access other NEs. You need not to add static routes on the T2000 or NEs.

3.4.2 Application 2: In Gateway NE Mode (by Default Gateway) If the T2000 connects with the GNE through a router and other NEs are accessed in the gateway NE mode, you need to add a default gateway on the T2000 and on the GNE.

Background Information As shown in Figure 3-2, the T2000 with the IP address of 10.100.11.12 connects with the GNE (NE1) through a router and accesses other NEs in the gateway NE mode. In this case, you need to set a default gateway on both the T2000 and NE1. Set the default gateway on the T2000 to 10.100.11.1, and that on NE1 to 129.9.0.254.

5. Click OK.

----End

3.4.3 Application 3: In Direct Connection Mode (by Static Routes) If the T2000 and the GNE connect to the same Ethernet and other NEs are accessed in the direct connection mode, you need to set on the T2000 the default gateway to the IP address of the NE that is directly connected to the T2000. In addition, you need to add the static route to the non-GNEs, with the forwarding address as the IP address of the GNE.

Background Information As shown in Figure 3-3, if the T2000 with the IP address of 129.9.0.100 needs to access NE3 directly, you need to add the static route to 133.168.0.0/16 on the T2000.

Adding the static route to 133.168.0.0/16 indicates that the static routes in the whole network section 133.168.0.0/16 are added. Hence, the NM with the IP address of 129.9.0.100 can directly access the NE that belongs to the network section, such as NE2, NE3 and NE4.

OptiX OSN 8800 I/6800/3800 Configuration Guide 4 Creating a Network


4-1

4 Creating a Network

About This Chapter You can use the T2000 to create a subnet, an NE, and the topology of fibers or cables, and to configure NE data, check or modify board parameters. You can also use the T2000 to manage the subnet, NE, and fibers or cables.

4.1 Network Creation Procedure

You can refer to the following procedure to create a network.

4.2 Creating NEs

Each equipment is represented as an NE on the T2000. Before the T2000 manages the actual equipment, you need to create the corresponding NEs on the T2000. There are two methods of creating NEs: creating a single NE and creating NEs in batches. When you need to create a large number of NEs, for example, during deployment, it is recommended that you create NEs in batches. When you need to create only a few NEs, it is recommended that you create the NEs one by one.

4.3 Configuring Master/Slave Subrack

The OptiX OSN 6800 and OptiX OSN 8800 I support the management of master/slave subracks. When multiple subracks are required for an NE, the master/slave subrack mode must be adopted for centralized management. In this mode, multiple subracks are displayed as one NE in the T2000.

4.4 Creating Optical NEs

The T2000 allocates the WDM equipmentinto different optical NEs for management. There are four types of optical NEs. They are WDM_OADM, WDM_OEQ, WDM_OLA and WDM_OTM. OptiX OSN 8800 I/6800/3800 only support WDM_OTM, WDM_OLA and WDM_OADM.

4.5 Creating an NE User

To ensure NE data security, only the users with NE user authority can log in to the NEs. An NE user is able to perform operations on the NEs according to the assigned authority. The T2000 administrator is advised to create NE users before configuring services.

4.6 Switching a Logged-In NE User

During a new deployment, after the root NE user creates the NE, this user can create another NE user. You can log in to the NE with the new NE user name.

4 Creating a Network OptiX OSN 8800 I/6800/3800

Configuration Guide


Issue 21 (2009-08-10)

4.7 Configuring the NE Data

Though an NE is successfully created, it is not configured. You need to configure the NE first so that the T2000 can manage and operate the NE.

4.8 Configuring Boards

In the NE Panel, you can add a board and set port attributes for the board.

4.9 Creating Fibers

A link is a physical or logical connection between two topological objects in the Main Topology. When configuring or managing the network by using the , you need to create links between different topological objects.

4.10 Configuring NE Clock Sources

The time source for a WDM NE is determined by the clock used by the SCC board.

4.2 Creating NEs Each equipment is represented as an NE on the T2000. Before the T2000 manages the actual equipment, you need to create the corresponding NEs on the T2000. There are two methods of creating NEs: creating a single NE and creating NEs in batches. When you need to create a large number of NEs, for example, during deployment, it is recommended that you create NEs in batches. When you need to create only a few NEs, it is recommended that you create the NEs one by one.

4.2.1 Creating NEs in Batches

When the T2000 communicates properly with a GNE, you can search for all NEs that communicate with the GNE by using the IP address of the GNE or the network segment to which the IP address is associated. Then, you can create NEs in batches. This method is quicker and more accurate than manual creation.

4.2.2 Creating a Single NE

After the NE is created, you can use the T2000 to manage the NE. Although creating a single NE is not as fast and exact as creating NEs in batches, you can use this method regardless of whether the data is configured on the NE or not.

4.2.1 Creating NEs in Batches When the T2000 communicates properly with a GNE, you can search for all NEs that communicate with the GNE by using the IP address of the GNE or the network segment to which the IP address is associated. Then, you can create NEs in batches. This method is quicker and more accurate than manual creation.

Prerequisite You must be an NM user with "NE administrator" authority or higher.

The T2000 must communicate properly with the GNE.

The NE Explorer instance of the NEs must be created.

Procedure Step 1 Choose File > Search > Auto Discovery... from the Main Menu. The Auto Discovery

window is displayed.

Step 3 Set Address type to IP Address Range of GNE, IP Address of GNE, or NSAP Address, and enter Search Address, User Name, and Password. Then, click OK.

You can repeat Steps 2 through 3 to add more search domains. You can delete the system default search domain.

If you use IP address to search for NEs: Usually, the broadcast function is disabled on the routers on a network, to avoid network broadcast

storm. Therefore, by using the IP Address Range of GNE method, only the NEs in the same network segment can be searched out.

To search the network segments across routers, the IP Address of GNE method is recommended. Through a gateway NE, you can search out the NEs in the network segment of the gateway NE.

Step 4 In the Search for NE dialog box, you can perform the following operations:

Select Search for NE and click OK to search for all NEs in the selected domain. Select Create device after search, and enter NE user and Password. Then, click OK.

The default NE user is root. The default password is password.

Select Upload after create and click OK, so that the NE data can be uploaded to the T2000 after the NE is created.

If you select all options in the Search for NE dialog box, you can search for NEs, create the NEs, and upload the NE data at one time.

4.12 Configuring the NE Time Time consistency between the T2000 and NEs is very important for troubleshooting and network monitoring. You should set the T2000 time and NE time before service configuration.

4.12.1 Time Synchronization Schemes for the T2000 and NEs

With the time synchronization function, consistency is maintained between the NE time and the T2000 server time. In this way, the T2000 is able to record the correct time at which alarms occur and the correct time at which the abnormal events are reported by NEs.

4.12.2 Synchronizing the NE Time with the T2000 Server Automatically

The NE time can be automatically synchronized with the T2000 server time. In this way, the time of alarms and logs can be correctly recorded in the T2000.

4.12.3 Synchronizing the NE Time with the T2000 Server Manually

In the case of NEs that do not have the NTP service configured, you need to check whether the NE time is consistent with the T2000 server time, so that the T2000 can correctly record the time of alarm generation. Otherwise, manually synchronize the NE time with the time of the T2000 server.

4.12.4 Configuring the Standard NTP Key



4-41

On the T2000, you can use the standard network time protocol (NTP) service to automatically synchronize the NE time with the standard NTP server time. To ensure that a reliable server is accessed, the NTP authentication function must be started. In this case, you need to set the key and password, which are authenticated together to check whether the server is reliable.

4.12.5 Synchronizing the NE Time with the Standard NTP Server Time

You can use the standard network time protocol (NTP) service to automatically synchronize the NE time with the standard NTP server time.

4.12.1 Time Synchronization Schemes for the T2000 and NEs With the time synchronization function, consistency is maintained between the NE time and the T2000 server time. In this way, the T2000 is able to record the correct time at which alarms occur and the correct time at which the abnormal events are reported by NEs.

When NEs report alarms and abnormal events to the T2000, the time at which such alarms and events occur is based on the NE time. If the NE time is incorrect, then the wrong time with regard to the occurrence of alarms is recorded in the T2000. This may cause trouble in fault location. In addition, the wrong time with regard to the occurrence of abnormal events is recorded in the NE security logs. To ensure the NE time accuracy, the T2000 provides two time synchronization schemes: synchronizing with the T2000 server and synchronizing with the standard NTP server and synchronizing with the standard NTP server.

If you use the scheme of synchronizing with the T2000 server, all NEs use the T2000 server time as the standard time. The NE time can be synchronized with the T2000 server time manually or automatically. The T2000 server time refers to the system time of the workstation or computer where the T2000 server resides. This scheme features easy operation, and is applicable in networks that require a low accuracy with regard to time.

If you use the scheme of synchronizing with the standard NTP server, all NEs and the T2000 are synchronized with the standard NTP server automatically. The NTP server can be the T2000 server or a special time server. This scheme is applicable in networks that require a high accuracy with regard to time.

4.12.2 Synchronizing the NE Time with the T2000 Server Automatically

The NE time can be automatically synchronized with the T2000 server time. In this way, the time of alarms and logs can be correctly recorded in the T2000.

Prerequisite You must be an NM user with "NE operator" authority or higher. The NTP service must not be configured for the T2000 and NEs.

Background Information Synchronizing the NE time does not affect services. Before synchronizing the NE time, verify that the system time on the T2000 server is correct. If you want to change the system time, exit the T2000 to reset the time and then start the T2000 again.

6 Configuring Wavelength Grooming

About This Chapter 6.1 Basic Concepts

OptiX OSN 6800 and OptiX OSN 8800 I provide reconfigurable optical add/drop multiplexer (ROADM) function. The T2000 is used to configure the add/drop and the pass-through state of channels, and thus the remote dynamic adjustment of channels is enabled. Optical power equalization can be performed on passthrough and adding wavelengths.

6.2 Wavelength Grooming Configuration Flow

This section describes the configuration process related to wavelength grooming. Before configuring wavelength grooming based on the configuration flow, complete the basic configuration of NEs according to the configuration flow of creating a network.

6.3 Configuring the ROADM

This section considers project R as an example to describe how to configure the ROADM on the T2000 when the WSS board is used.

6.4 Parameters

Describes the parameters involved in the wavelength grooming configuration.

6.1 Basic Concepts OptiX OSN 6800 and OptiX OSN 8800 I provide reconfigurable optical add/drop multiplexer (ROADM) function. The T2000 is used to configure the add/drop and the pass-through state of channels, and thus the remote dynamic adjustment of channels is enabled. Optical power equalization can be performed on passthrough and adding wavelengths.

There are two schemes supported by the WDM equipment for wavelength allocation:

Fixed optical add/drop multiplexer (FOADM) Reconfigurable optical add/drop multiplexer (ROADM)

FOADM cannot reconfigure the wavelength allocation based on the requirements of service development. The ROADM realizes the reconfiguration of wavelengths by blocking or cross-connecting wavelengths, changing the static wavelength allocation to a flexible and dynamic operation. Making use of the ROADM technology, the T2000 software adjusts the

Issue 21 (2009-08-10)

status of wavelengths (add, drop or pass-through) to realize remote and dynamic adjustment of wavelength status. The adjustment of a maximum of 80 wavelengths is supported.

Optical grooming is the configuration of logical wavelength routes, realized by optical cross-connection. This function meets the user's requirement of managing the services at the optical layer. Products provides flexible optical grooming. When there are changes in the services, users need only to make configuration accordingly on the T2000.

Different nodes adopt different methods of optical grooming. The three main methods are listed as follows:

WSD9 + RMU9 (WSM9): Mainly applied to inter-ring nodes and suitable for multi-dimensional grooming. It supports the grooming of at most eight dimensions.

WSMD4+WSMD4: Mainly applied to inter-ring nodes and suitable for the grooming in no more than four dimensions.

ROAM: Applied to common nodes and suitable for two-dimensional grooming.

Dimension refers to transmission direction. Two-dimensional grooming refers to wavelength grooming in two transmission directions. Multi-dimensional grooming refers to wavelength grooming in multiple transmission directions.

For more details of optical grooming, refer to the Product Description.

6.2 Wavelength Grooming Configuration Flow This section describes the configuration process related to wavelength grooming. Before configuring wavelength grooming based on the configuration flow, complete the basic configuration of NEs according to the configuration flow of creating a network.

Configuration Guide


Issue 21 (2009-08-10)

7.1 Overview This topic describes the basic concepts of the WDM service configuration.

Overview of Cross-Connections The grooming function of electrical cross-connections of WDM equipment helps WDM networks to change from static networks to dynamic networks. Operations, such as pass-through, adding, dropping, loopback, can be performed on each sub-service on any station independently, without affecting the services in other channels. The electrical cross-connection realizes automatic configuration through remote management. No fiber jumper needs to be performed manually. In this manner, the operation cost and the possibility of misoperation are reduced.

Unlike the point-to-point multiplexing channel scheme of traditional WDM MUX/DMUX, the electrical cross-connections are added with, for example, GE and ODUk cross-connections and end-to-end management capability on the basis of the MUX/DMUX. In addition, the electrical cross-connection scheme is different from the ADM scheme that is based on wavelengths. It allows the cross-connection of services between wavelengths, providing service convergence and grooming of different wavelengths.

Electrical cross-connections are classified as follows:

According to the cross-connection level and granularity, electrical cross-connections are classified into, for example, GE, Any, and ODUk cross-connections.

According to the grooming mode, electrical cross-connections are classified into centralized cross-connections and distributed cross-connections.

According to the location of cross-connection, electrical cross-connections can be in straight-through mode or cross-connect mode. − Straight-through mode:

Optical signals received at the RXn port on the client side pass through the cross-connect unit and directly travel to the corresponding channels on the WDM side. After multiplexing, signal processing and optical wavelength conversion, these signals are output from the OUT port. After wavelength conversion and signal processing, signals input from the IN port on the WDM side are demultiplexed into one or more channels of electrical signals that pass through the cross-connect unit and directly travel to the corresponding TXn on the client side. Straight-through services are as shown in the Figure 7-1:

− 3 (RX1/TX1) (client-side optical interfaces) <-> 3 (channel number) − 4 (RX2/TX2) (client-side optical interfaces) <-> 4 (channel number) − 5 (RX3/TX3) (client-side optical interfaces) <-> 5 (channel number) − 6 (RX4/TX4) (client-side optical interfaces) <-> 6 (channel number)

− Cross-connect mode: Cross-connections in cross-connect mode are classified into intra-board cross-connections and inter-board cross-connections.

− Intra-board cross-connection: Optical signals received at the RXn port on the client side are cross-connected by the cross-connect unit to the channels that correspond to other optical interfaces of the same board on the WDM side. After multiplexing, signal processing and optical wavelength conversion, these signals are output from the OUT port. After wavelength conversion and signal processing, signals input from the IN port on the WDM side are demultiplexed into multiple channels of electrical signals, one channel of which is cross-connected by the cross-connect unit to the client-side TXn port that corresponds to other channels of the same board. The intra-board cross-connection service is as shown in the Figure 7-2: 5 (RX1/TX1) (client-side optical interfaces) <->3 (channel number).

− Inter-board cross-connection: Optical signals received at the RXn port on the client side are cross-connected by the cross-connect unit to the channels that correspond to optical interfaces of another board on the WDM side. After multiplexing, signal processing and optical wavelength conversion, these signals are output from the OUT port. After wavelength conversion and signal processing, signals input from the IN port on the WDM side are demultiplexed into multiple channels of electrical signals, one channel of which is cross-connected by the cross-connect unit to the client-side TXn port that corresponds to other channels of another board. The Inter-board cross-connection service is as shown in the Figure 7-2: 3 (RX1/TX1) (client-side optical interfaces) <->6 (channel number).

The straight-through and cross-connect services should be configured on the T2000. That is, create cross-connect services.

Restrictions on Cross-Connection Configuration Earlier version NE software does not support cross-connection creation between boards

of different types. As the NE software imposes restrictions on backplane cross-connections, the boards

between which you want to create cross-connections must be in cross-connect slots. In the case of different types of equipment, boards, and the corresponding NE software versions, their cross-connect slots and cross-connect groups are different.

If you configure a cross-connection between the two optical ports on the OTU board, the source of a normal cross-connection can also serve as the source of other normal cross-connections, but its sink cannot be the sink of other cross-connections. The two sources of a SNCP cross-connection cannot be the source of other cross-connections, and its sinks cannot be the sink of other cross-connections.

When configuring the electrical cross-connection for a service on the OptiX OSN 3800, OptiX OSN 6800, and OptiX OSN 8800 I, you must make sure that the WDM-side optical channel numbers at the transmit and receive ends of the service in a direction must be the same. Otherwise, the service fails.

The OptiX OSN 3800 provides mesh cross-connections in the four-slot group based on the GE service, ODU1 signal, and Any service.

Normal cross-connections on the OptiX OSN 6800 are classified into centralized cross-connections and distributed cross-connections.

Centralized cross-connection: If the XCS board is configured during the cross-connection creation, the cross-connection can be realized through the XCS. The boards where you want to create cross-connections can be placed in any slots that support the boards. If you want to delete the XCS board on the T2000, first delete the cross-connections that are related to the XCS board.

Distributed cross-connection: If no XCS board is configured during the cross-connection creation, the boards where you want to create cross-connections can be placed in paired slots.

The paired slots of the OptiX OSN 6800 are as follows: 1 and 2, 3 and 4, 5 and 6, 7 and 8, 9 and 10, 11 and 12, 13 and 14, and 15 and 16. The XCS boards are placed in slots 9 and 10.

On the OptiX OSN 8800 I, normal cross-connections support centralized cross-connections only.

Signal Flow of Electrical Cross-Connections In the case of the WDM equipment, the OTU board, tributary board, and line board work together to complete the cross-connect grooming of services. The client services are transmitted from the client side of the WDM equipment, and then modulated to the WDM system for transmission after service grooming and convergence. Figure 7-3 considers the OTU board with the GE/Any and ODUk cross-connection function as an module to describe the signal flow of the electrical cross-connection service of the OptiX OSN 3800 and OptiX OSN 6800.Figure 7-4 considers the OTU board with the ODUk cross-connection function as an module to describe the signal flow of the OTN electrical cross-connection service of the OptiX OSN 8800 I. Figure 7-5 describes the signal flow of the SDH electrical cross-connection service of the OptiX OSN 8800 I.

The signals are cross-connected in the following process:

1. The optical signals are transmitted to the OTU board through the TX/RX interface and become electrical signals. After the possible L2 processing, the electrical signals are transmitted to the GE/Any cross-connect module through the AP interface and work with the possible cross-connect signals from the backplane, to realize the GE/Any cross-connections.

2. The electrical signals are transmitted to the ODUk cross-connect module through the LP interface and work with the possible ODUk signals from the backplane, to realize the ODUk cross-connections. Then, the signals are transmitted to the optical module through an OP interface and then added to the WDM line for transmission.

The OptiX OSN 8800 I supports the electrical signals that are transmitted to the ODUk cross-connect module through the LP interface and work with the possible ODUk signals from the backplane, to realize the ODUk cross-connections. Then, the signals are transmitted to the optical module through an OP interface and added to the WDM line for transmission.

The boards that support the grooming of electrical cross-connections have both the external interfaces and internal interfaces. These interfaces are classified into the following types:

TX/RX interface: client-side optical interface of the board that receives and transmits signals. IP interface: internal interface that corresponds to the TX/RX interface. It can be regarded as a

TX/RX interface. AP interface: convergence interface that represents the internal interface of the L2 module. In this

case, the corresponding IP interface is an external interface. LP: logical interface that functions as the connection point of cross-connections. OP interface: internal interface that corresponds to the IN/OUT interface. It can be regarded as an

IN/OUT interface. IN/OUT interface: line-side optical interface of the board that receives and transmits signals.

Issue 21 (2009-08-10)

9.9 Monitoring Wavelengths by Using the MCA Board

If the system requires the multi-channel spectrum analyzer (MCA) board, you need to enable the MCA board to monitor wavelengths. The station that is configured with the MCA boards usually uses the MCA boards to check the OSNR of a single wavelength and check whether certain wavelengths are dropped.

9.10 Open and Close the Laser on the WDM Board

You can turn on or off a laser by setting the laser status.

9.11 Open and Close the Laser on the SDH Board

You can turn off or turn on a laser when necessary. For example, if an optical port does not carry services, you can turn off the laser to prevent hazardous laser radiation exposure from causing permanent eye damage. You can turn on the laser when the optical port needs to carry services.

9.12 Setting the Rated Optical Power of the OA Board

You can manually change the rated input and output optical power of an optical amplifier (OA) board as required to trigger a change in the attenuation of the power adjustment board.

9.13 Setting Dispersion Compensation Parameters

In a 40G system, you must accurately configure the fixed dispersion compensator. You also need to use the tunable dispersion compensator (TDC) to adjust dispersion precisely. In addition, you need to use TDC dispersion real-time adjustment to rectify dispersion offsets of transmission fibers caused by changes in factors such as ambient temperature.

9.14 Configuring the Working Mode of the 52TOM Board

Before using the 52TOM board, you need to configure the board working mode and port working mode for the 52TOM board.

9.15 Configuring the Working Modes of Ordinary OTUs

Before you use OTU boards such as the 11TOM, you need to configure the working modes of the boards.

9.16 Configuring the Service Mode

If services such as OTU1 are input to a board, you need to configure the service mode of the board.

9.17 Enable the Open Fiber Control (OFC)

The open fiber control (OFC) function controls the transmit power of the laser when the fiber is disconnected. When the OFC function is enabled, the laser sends short pulse, rather than remains in the enabled state, to check whether the fiber is connected. In this way, the output optical power of the laser is cut, which prevents eye injury.

9.18 Setting Automatic Laser Shutdown on the WDM Board

Automatic laser shutdown is a function of automatically shutting down the laser when there is no input light and the laser stops emitting optical signals. For example, when an optical interface board does not bear services, a fault occurs on the fiber, or the received optical signals are lost, the laser is automatically turned off. This reduces the on period of the laser, extends the service life of the laser, and prevents hazardous laser radiation exposure from causing permanent eye damage.

9.19 Setting Automatic Laser Shutdown on the SDH Board



9-3


9.20 Configuring Protection Trigger Conditions

You can set the signal degrade (SD) as the trigger condition of automatic protection switching for the OptiX OSN 8800 I/6800/3800.

9.21 Setting the NULL Mapping Status

Some OTU boards in the NG WDM equipment support the OTN NULL mapping detection. For the channel where no signals are input, the T2000 can be used to set the NULL mapping status to Enabled. By checking OTN overheads, the channel status in the network can be monitored.

9.22 Configuring Path Binding

By configuring path binding, you can realize inverse multiplexing of client side signals to multiplex the higher order signal accessed from the client side to several channels of lower order signals. In this way, the bandwidth of the optical interface decreases.

9.23 Configuring Centralized Wavelength Monitoring

The WMU board is connected to the MON interfaces of the optical amplifier boards or optical multiplexer boards in the two transmit directions. The board monitors the wavelengths and reports information such as optical power of the wavelengths to the SCC. To realize the function, the OTU board and NE where the monitored wavelength locates must be configured on the T2000, and the intra-subrack and inter-subrack communication must be normal.

9.24 Configuring the FEC Function

When configuring the forward error correction (FEC) function of a board, you need to enable the function and set the FEC type of the current optical interface.

9.25 Enabling and Disabling LPT

When the overhead byte supporting the LPT protocol is added in the frame format of the WDM-side signals, the running status of the network access point or the service network can be monitored.

9.26 Backing Up and Restoring the NE Data

For the security of the NE data, you can back up and restore the NE data.

9.1 Configuring the ROADM You can configure the ROADM of the WSS type by following the instructions below.

9.1.1 Configuring the Edge Port

An edge port refers to the port that is connected to another NE by fiber. Setting an edge port is to set an optical port of an NE as a connection point between this NE and another NE.

9.1.2 Creating Single-Station Optical Cross-Connection


Configuration Guide


Issue 21 (2009-08-10)

Optical cross-connection defines the routes of wavelengths. Through the creation of single-station optical cross-connection, the routes of inter-board services are configured.

9.1.3 Creating Single-Board Optical Cross-Connection

The intra-board optical wavelength route can be set for a board (WSD9/WSM9/ROAM) that performs grooming at the optical layer. The intra-board service route is established through the creation of single-board optical cross-connection.

9.1.1 Configuring the Edge Port An edge port refers to the port that is connected to another NE by fiber. Setting an edge port is to set an optical port of an NE as a connection point between this NE and another NE.


Background Information

The line-side ports of the FIU and the OTU do not need this configuration. By default, such a port is a Fixed Edge Ports.

9.1.2 Creating Single-Station Optical Cross-Connection Optical cross-connection defines the routes of wavelengths. Through the creation of single-station optical cross-connection, the routes of inter-board services are configured.


The logic fiber connection inside a single station has been set up on the T2000.

The edge port must be configured.

When creating an optical cross-connection of a single station, make sure that the optical cross-connection of a board in this single station does not occupy the wavelength that the optical cross-connection of the single station uses.

Background Information When you create an optical cross-connection, the optical power can be adjusted automatically or manually. If you select Auto, the dynamic optical add/drop multiplexing board automatically adjusts the attenuation range of the optical attenuator in the board. If you select Manual, you need to manually adjust the attenuation range of the optical attenuator in the dynamic optical add/drop multiplexing board. The Auto option is available for the following types of optical cross-connection trails:

Passthrough service, such as OA > WSD9 > WSM9 > OA, OA > WSD9 > RMU9 > OA, and OA > ROAM > ROAM > OA.

Add service, such as OTU > WSM9 > OA, OTU > RMU9 > OA, and OTU > ROAM > OA.

Drop service, such as OA > WSD9 > OTU.

The WSMD4 can be used to replace the WSD9 or the WSM9. OA indicates the optical amplifier boards such as OAU1 and OBU1. The FIU can be added before or after the OA. In drop networking, the demultiplexer boards such as D40, D40V and MR2 can be added between the WSD9 and OTU. In add networking, the multiplexer boards such as M40, M40V and MR2 can be added between the OTU and WSM9.

The optical cross-connect services created are unidirectional. The reverse services need to be configured in addition. The configuration in the other direction is similar. Optical cross-connections are created by creating optical cross-connections on the board or on a single station. Creating optical cross-connections on a single station is recommended.

Background Information Single-board optical cross-connection and single-station optical cross-connection are independent from each other. The user can create single-board optical cross-connection and configure services based on the planning to realize grooming at the optical layer. However, as for the single-station optical cross-connection, grooming is realized after automatic computation of the equipment. The configuration of single-board optical cross-connection and that of single-station optical cross-connection are mutually exclusive in terms of resources. When the user configures an optical-layer grooming board with the single-board optical cross-connection of one wavelength, this wavelength can no longer be configured for single-station optical cross-connection.

This section describes several NE data backup and restoration methods. You can select the method as required.

9.26.2 Backing Up the NE Database to the SCC Board

You need to back up the NE database during daily maintenance, to ensure that the SCC board of the NE automatically restores to normal operation after a data loss or equipment power failure. When you back up the NE database to the SCC board, you actually back up the NE data in the DRDB database of the SCC board to the Flash database. When the NE is restarted after a power failure, the SCC board automatically reads the configuration from the FLASH and issues the configuration to the boards.

9.26.3 Manually Backing Up the NE Database to a CF Card

You need to back up the NE database during the daily maintenance. You can back up the NE data in the DRDB database of the SCC board to a CF card manually, to ensure the automatic restoration of the operation after the data in the DRDB database is lost on the SCC board or a power failure occurs on the equipment.

9.26.4 Backing Up Device Data to the NMS Server or the NMS Client

This operation describes how to backup device data manually for multiple device(s) of same device type. You can backup device data to the NMS server or the NMS client.

9.26.5 Restoring the NE Database from the SCC Board

When the database file is lost due to the NE maintenance or NE fault, you can restore the NE data from the DRDB database file that is already backed up to the Flash database on the SCC board.

9.26.6 Restoring the NE Database from the CF Card

This section describes several NE data backup and restoration methods. You can select the method as required.



9-33

Comparison of Backup and Restoration Methods The locations for backing up and restoring the NE database include the SCC board, CF card, local server and remote server. Different storage locations determine different types of backup and restoration methods. See Table 10-1.

Table 9-1 Backup and restoration methods and application scenarios

Backup and Restoration Method Application Scenario

Back up/Restore the NE database to/from an SCC board

Backs up the NE data in the DRDB database of the SCC board to the flash database, when the SCC board does not have a CF card. During the restoration, after a warm reset or a cold reset on the SCC board, the SCC board reads the configuration from the flash database and issues the configuration to other boards.

Back up/Restore the NE database to/from a CF card

Backs up the NE data in the DRDB database of the SCC board to the CF card, when the SCC board has a CF card. During the restoration, the database is restored from the CF card to the DRDB database of the SCC board. After a warm reset or cold reset on the SCC board, the memory database on the SCC board is updated. Then, after the warm resets on other boards, the NE memory data is issued to the boards.

Back up/Restore the NE data to/from an NMS server

Stores the data in the computer where the NMS server resides. During restoration, you can select the backup file in the directory where the NE data is saved.

Back up/Restore the NE data to/from an NMS client

Stores the data in the computer where the NMS client resides. During restoration, you can select the backup file in the directory where the NE data is saved.

NE Database The NE configuration data is saved in the NE database. There are three types of NE databases as follows:

MDB: Memory database. The data in a MDB database is changed when the configuration information is changed. The data is lost when the SCC board is reset or a power failure occurs.


Configuration Guide


Issue 21 (2009-08-10)

DRDB: Dynamic random database. The data that is verified is automatically saved in the DRDB database.

FDB: Flash database. There are the FDB0 and FDB1 databases. The data need to be copied to the database manually and can be saved permanently.

When the NE configuration data is issued to the SCC board, it is saved in the MDB database. If the verification is successful, the SCC board automatically copies the contents in the MDB database to the DRDB database and issues the verified configuration data to the boards. You need to manually copy the DRDB database to the FDB database, as a backup of the DRDB database. When the NE is restarted after a power failure, the SCC board checks whether there is configuration data in the DRDB database. If yes, the data are restored from the DRDB database. If the data in the DRDB database is damaged, the data is restored from the FDB0 and FDB1 databases.

NE Configuration Data The NE configuration data refers to the information in the DRDB database of the NE, such as the board configuration, clock configuration and protection relations of the NE. It is the instruction file of the NE and the key for the NE to perform normally in the entire network.

NE Database Package The NE database package is a package that contains all database files on an NE and a file list that defines and manages those files.

The NE database package and NE configuration data are the same data on the NE in different releases. You can perform the NE database package backup and restoration on the release 5.00.06 NE or the NE of later release.
