3 Preparations

3.1 Preparing Documents For a deployment of the OptiX OSN 1800 equipment, you need to prepare documents, including station bar code return table, engineering design documents, and product manuals, according to the actual project.

Station Bar Code Return Table The station bar code return table is used to collect the bar codes of the sets of equipment installed at a station. After all sets of equipment at a station are installed, you need to record the bar codes of the equipment in the station bar code return table. The station bar code return table shows the mapping relationships between bar codes and station names. Therefore, it must be kept properly for future identifying the station where an NE is located when the ID and name of the NE are changed according to the customer planning.

Engineering Design Documents The engineering design documents are important inputs for equipment commissioning. Generally, the following contents are covered: l

Network diagrams: describe the module types, number of add and drop wavelengths, NE types and quantity, and NE IDs of each station, distance between adjacent stations, line attenuation between stations, and network topology.

l

Amplifier configuration diagrams: describe the amplifier configuration and line attenuation at each station.

l

Wavelength allocation diagrams: describe the wavelength numbers at each station, service relationships between stations (add, drop, or pass-through), and wavelength protection relationships.

l

Fiber connection diagrams: describe the internal and external fiber connection relationships, and slots, optical interfaces on the chassis and ODF terminals at each station.

Product Manuals The product manuals of the OptiX OSN 1800 equipment cover the equipment functions, features, and guides to the installation, commissioning, configuration, maintenance, and troubleshooting of the equipment. In the equipment deployment phase, you are recommended to read this manual, that is, OptiX OSN 1800 Compact Multi-Service Edge Optical Transport Platform Commissioning and Configuration Guide. The reference manuals are as follows:

You can log in to the Web site http://support.huawei.com to download the product manuals of the OptiX OSN 1800 equipment. The path is Documentation > Optical Network > Optical Network Product Line > WDM > OptiX OSN 1800.

3.2 Preparing Tools, Meters, and Materials You are recommended to use the Web LCT for the commissioning and configuration of the OptiX OSN 1800 equipment. The version of the commissioning tool must match the equipment version.

Commissioning Tool You can use either the T2000 or the Web LCT for the commissioning and configuration of the OptiX OSN 1800 equipment. Compared with the T2000, the Web LCT has lower requirements on the computer hardware and can be started quickly. Therefore, the Web LCT is recommended at the commissioning and configuration phases. The Web LCT, however, does not support query or configuration of network-level functions. Therefore, the query and configuration of network-level functions must be performed on the T2000. You can log in to the Web site http://support.huawei.com to download the required version of the T2000 and Web LCT. The path is Software Center > Version Software > Optical Network Product Line > Optical Network Management System. NOTE

The versions of the T2000 and Web LCT must match the version of the equipment. For the matching product versions of this document, see About This Document. NOTE

When you use the T2000 for the commissioning and configuration, you must be an NM user with "NE operator" authority or higher.

Commissioning Meters An optical power meter and an optical spectrum analyzer are mainly used for optical power commissioning. The optical spectrum analyzer may be used only for commissioning of a network that is configured with optical amplifier (OA) boards. The optical power meter can be used for testing the total optical power of multiplexed signals and optical power of the optical transponder unit (OTU) boards. The optical spectrum analyzer can be used for testing the optical power, optical signal-to-noise ratio (OSNR), and center wavelength of a single wavelength of the multiplexed signals. You are required to test the optical power of a single wavelength of the multiplexed signals by using the optical spectrum analyzer because the test result is more accurate and the impact of the noise does not need to be considered. The meters must be calibrated before being used. Issue 02 (2010-09-30)

4 Commissioning Optical Power

Commissioning Optical Power

About This Chapter The optical power must be first commissioned in the deployment commissioning to ensure normal communication between all NEs and normal optical power received by each board. If the actual line attenuation is consistent with the design attenuation, the optical power is supposed to be within the normal range after the hardware installation engineers install the FOAs correctly according to the engineering design documents. 4.1 Commissioning a System Without Optical Amplifiers When commissioning a system without optical amplifiers (OAs), pay attention to the receive optical power of OTU boards. 4.2 Commissioning a System with Optical Amplifiers When commissioning the optical power of a system with optical amplifiers (OAs), pay attention to the output optical power of OAs, the receive optical power of corresponding OTU boards, and the input optical power of the DCM module. 4.3 Checking the Optical Power Commissioning Results When optical power commissioning is complete, you need to check the optical power commissioning results.

4.1 Commissioning a System Without Optical Amplifiers When commissioning a system without optical amplifiers (OAs), pay attention to the receive optical power of OTU boards.

General Requirements The general requirements for commissioning the optical power of a system without OAs are as follows: l

The optical power after commissioning must be within the permitted range.

l

A certain optical power margin must be reserved to ensure that optical power fluctuation in a certain range does not affect the existing services.

Requirements on OTU Optical Power The output optical power of an OTU board must conform to the optical power specifications of the OTU board. For details on the optical power specifications of the OTU board, see the Hardware Description. After commissioning, the receive optical power of the OTU board must satisfy the following formula: Lower threshold of the receive optical power ≤ Receive optical power of the OTU board ≤ Upper threshold of the receive optical power. It is recommended that the receive optical power of an OTU board after commissioning is equal to the average value of the upper and lower thresholds in practical application. The optical power on the WDM side of the OTU board must satisfy the following formulas: l

Lower threshold of the receive optical power = Receiver sensitivity + 3 dB

l

Upper threshold of the receive optical power = Receiver overload point - 5 dB

The optical power on the client side of the OTU board must satisfy the following formulas: l


l


General Commissioning Methods In general, commission a system without OAs along the signal flow, that is, from the upstream direction to the downstream direction, according to the requirements on the OTU optical power. Measure the receive and transmit optical power of an OTU board by using an optical power meter, or query the receive and transmit optical power of the OTU board on the Web LCT or T2000.

Issue 02 (2010-09-30)



CAUTION In the commissioning process, ensure that the input optical power of an OTU board (either the WDM or client side) is lower than the optical power at the overload point to prevent the receiver optical module from being damaged or prevent the existing services from being affected. Exercise caution especially when an APD receiver optical module is used because the overload point of such an optical module is only -9 dBm. Hence, connect a fiber loosely or do not connect a fiber to the input optical interface on the OTU board before measuring the actual input optical power.

If the receive optical power on the WDM side of the OTU (recorded as P1) fails to meet the optical power requirement, do as follows: l

If P1 is higher than the upper threshold of the receive optical power, attach an appropriate fixed optical attenuator to the receive optical interface (point B in Figure 4-1) on the WDM side of the OTU board to ensure that P1 meets the optical power requirement.

l

If P1 is lower than the lower threshold of the receive optical power, substitute a fixed optical attenuator with lower attenuation for the existing fixed optical attenuator or remove the fixed optical attenuator attached to the receive optical interface (point B in Figure 4-1) on the WDM side of the OTU board. If P1 still fails to meet the optical power requirement after the fixed optical attenuator is removed, check whether the fiber attenuation on the line is proper and whether the network design data is correct.

If the receive optical power on the client side of the OTU (recorded as P2) fails to meet the optical power requirement, do as follows: l

If P2 is higher than the upper threshold of the receive optical power, attach an appropriate fixed optical attenuator to the receive optical interface (point A in Figure 4-1) on the client side of the OTU board to ensure that P2 meets the optical power requirement.

l

If P2 is lower than the lower threshold of the receive optical power, substitute a fixed optical attenuator with lower attenuation for the existing fixed optical attenuator or remove the fixed optical attenuator attached to the receive optical interface (point A in Figure 4-1) on the client side of the OTU board. If P2 still fails to meet the optical power requirement after the fixed optical attenuator is removed, check whether the transmit optical power of the upstream equipment is within the permitted range, whether the fiber attenuation on the line is proper, and whether the network design data is correct.

If the output optical power of the OTU board fails to meet the optical power requirement on OTU boards, replace the corresponding optical module.

Tools, Meters, and Materials Optical power meter, Web LCT or T2000, fiber jumpers (two FC/PC-FC/PC, LC/PC-LC/PC, and LC/PC-FC/PC fiber jumpers), several fixed optical attenuators (3 dB, 5 dB, 7 dB, 10 dB, and 15 dB), fiber adapters, fiber cleaning tissue or cassette cleaner, and compressed air cleaner.

4.2 Commissioning a System with Optical Amplifiers When commissioning the optical power of a system with optical amplifiers (OAs), pay attention to the output optical power of OAs, the receive optical power of corresponding OTU boards, and the input optical power of the DCM module.

General Requirements The general requirements for commissioning the optical power of a system with OAs are as follows: l

The optical power after commissioning must be within the permitted range.

l

A certain optical power margin must be reserved to ensure that optical power fluctuation in a certain range does not affect the existing services.

l

The optical power after commissioning must meet the requirements on system expansion.

Requirements on OTU Optical Power The output optical power of an OTU board must conform to the optical power specification of the OTU board. For details on the specifications of the OTU board, see the Hardware Description. After commissioning, the receive optical power of the OTU board must satisfy the following formula: Lower threshold of the receive optical power ≤ Receive optical power of the OTU board ≤ Upper threshold of the receive optical power. It is recommended that the receive optical power of an OTU board after commissioning is equal to the average value of the upper and lower thresholds in practical application. The optical power on the WDM side of the OTU board must satisfy the following formulas: l


l


The optical power on the client side of the OTU board must satisfy the following formulas: l


l


Requirements on OA Optical Power The average output optical power of the wavelengths of an OA must be equal to the nominal output optical power for a single wavelength. In this case, the following requirements must be met: 4-4


Issue 02 (2010-09-30)



l

The average output optical power of the wavelengths of an OA is measured by connecting an optical spectrum analyzer to the OUT optical interface on the OA.

l

Nominal output optical power for a single wavelength = Maximum total optical power of the OA - 10lgN (N represents the maximum number of wavelengths permitted by the system). For example, the maximum total optical power of the OA is 17 dBm. If the system is designed as a 40-channel system, the nominal output optical power for a single wavelength is 1 dBm as calculated by using the preceding formula.

The output optical power of a single wavelength of the OA should be equal to or close to the nominal output optical power for a single wavelength.

Requirements on DCM Optical Power If a DCM module is configured in a system, the optical power of a single wavelength input to the DCM module must be equal to or lower than -3 dBm.

General Commissioning Methods In general, commission a system with OAs along the signal flow, that is, from the upstream direction to the downstream direction, according to the requirements on the OA optical power, OTU optical power, and DCM optical power. The optical power of an OTU board is commissioned in the same way regardless of in a system with OAs or a system without OAs. For the detailed methods of commissioning the optical power of an OTU board, see 4.1 Commissioning a System Without Optical Amplifiers.

CAUTION In the commissioning process, ensure that the input optical power of an OTU board (either the WDM or client side) is lower than the optical power at the overload point to prevent the receiver optical module from being damaged or prevent the existing services from being affected. Exercise caution especially when an APD receiver optical module is used because the overload point of such an optical module is only -9 dBm. Hence, do not connect a fiber or connect a fiber loosely to the input optical interface on the OTU board before measuring the actual input optical power.

Connect an optical spectrum analyzer to the OUT optical interface on an OA, and then measure the output optical power of a single wavelength and the average output optical power of the wavelengths of the OA. If the output optical power of a single wavelength of the OA fails to meet the optical power requirement, adjust the optical attenuator at the WDM-side output optical interface on the upstream OTU board or adjust the optical attenuator at the input optical interface on the OA to ensure that the optical power of the OA meets the optical power requirements. See Figure 4-2. In the case of OA1, do as follows: l

If the average output optical power of wavelengths is higher than the nominal output optical power for a single wavelength, increase the attenuation of the optical attenuator at the input optical interface (point as D in Figure 4-2) on the OA to ensure that the average optical power of wavelengths is equal to the nominal output optical power for a single wavelength.

l

If the average output optical power of wavelengths is lower than the nominal output optical power for a single wavelength, decrease the attenuation of the optical attenuator at the input optical interface (point as D in Figure 4-2) on the OA to ensure that the average optical power of wavelengths is equal to the nominal output optical power for a single wavelength.

l

In the case of the output optical power of a specific wavelength, adjust the optical attenuator at the output optical interface (point C in Figure 4-2) on the corresponding OTU board to ensure that the output optical power of this wavelength from the OA is equal to or close to the nominal output optical power for a single wavelength.

In the case of OA2, adjust the optical attenuator at point E in Figure 4-2 to ensure that the average optical power of wavelengths is equal to the nominal output optical power for a single wavelength. If the average output optical power of wavelengths cannot be equal to the nominal output optical power for a single wavelength after the attenuation is adjusted to 0, remove the optical attenuator. If the optical power requirement is still not met, check whether the network design data is correct. In the case of OA3, adjust the input optical power of the MUX2 board at the upstream station, and then adjust the optical attenuator at point F in Figure 4-2 to ensure that the average output optical power of wavelengths of the OA is equal to the nominal output optical power for a single 4-6


Issue 02 (2010-09-30)



wavelength. The methods of commissioning the input optical power of the MUX2 board are as follows: 1.

Measure the optical power of each pass-through wavelength at the input optical interface on the MUX2 board and then calculate the average optical power of these pass-through wavelengths. In the case of a multiplexed pass-through wavelength, measure the average optical power by using an optical spectrum analyzer. In the case of a single pass-through wavelength, measure the optical power of this pass-through wavelength directly by using an optical power meter.

2.

Measure the optical power of a single add wavelength at the input optical interface on the MUX2 board and identify the add wavelength with the lowest optical power.

3.

Do as follows to adjust the optical power of corresponding wavelengths: l If the average optical power of the pass-through wavelengths is lower than the lowest optical power of the add wavelengths, adjust the optical attenuator at point G in Figure 4-2 to ensure that the optical power of each add wavelength is equal to the average optical of the pass-through wavelengths. l If the average optical power of the pass-through wavelengths is higher than the lowest optical power of the add wavelengths, install one optical attenuator on each pass-through channel between the DUX1 and MUX2 boards to ensure that the average optical power of the pass-through wavelengths is equal to the lowest optical power of the add wavelengths. In addition, adjust the attenuation of the optical attenuators at the output optical interfaces on other OTU boards used to add wavelengths. This is to ensure that the optical power of each add wavelength is equal to the lowest optical power of the add wavelengths as measured at the input optical interface on the MUX2 board. TIP

If the OPU board is configured with SFP EVOA, the attenuation value can be adjusted on the NMS.

If a DCM module is configured in the system, measure the total input optical power of the DCM module by using an optical power meter. Then, calculate and ensure that the actual input optical power of a single wavelength is equal to or lower than -3 dBm.

Tools, Meters, and Materials Optical power meter, optical spectrum analyzer, Web LCT or T2000, fiber jumpers (two FC/ PC-FC/PC, LC/PC-LC/PC, and LC/PC-FC/PC fiber jumpers), several fixed optical attenuators (3 dB, 5 dB, 7 dB, 10 dB, and 15 dB), fiber adapters, fiber cleaning tissue or cassette cleaner, and compressed air cleaner.

4.3 Checking the Optical Power Commissioning Results When optical power commissioning is complete, you need to check the optical power commissioning results.

Procedure Step 1 Check whether communication of all stations on the network is normal. For the checking methods, see 5.1 Searching for and Creating NEs. If communication of an NE is interrupted or the NE is abnormal, check whether the fiber connection is correct onsite. Step 2 Check whether alarms indicating excessively high or low optical power, or bit error threshold crossing exist on the network. For the checking and handling methods, see 5.20 Viewing Current Alarms on an NE and Removing Abnormal Alarms. Step 3 Check whether before-FEC and after-FEC bit errors of the boards that support the FEC function are normal. For the checking methods, see 5.19 Querying Bit Errors Before and After FEC. Step 4 See the preceding procedure to check and ensure that all optical power values on the network are normal, and then save the networkwide optical power data.

5 Commissioning and Configuring the Network

Commissioning and Configuring the Network

About This Chapter You can commission and configure the network after the equipment at each station on the network is powered on and the stations are interconnected with fibers. 5.1 Searching for and Creating NEs You can search for and create NEs when the NEs are connected to the NMS computer and the communication between NEs and the NMS is normal. 5.2 Creating Optical NEs On the T2000 the WDM equipment is allocated to different optical NEs for management. 5.3 Changing the ID and Name of an NE The ECC protocol uses an NE ID to uniquely identify an NE. When planning the network, you must assign a unique ID for each NE. If an NE ID conflicts with another one, ECC routing collision is caused. In this case, certain NEs cannot be managed. 5.4 Changing the IP Address of an NE In the case of a gateway NE, change the IP address of the NE according to the customer planning. In the case of a non-gateway NE, you do not need to change its IP address. 5.5 Configuring Ethernet Extended ECC When there is no OSC or ESC communication between two or more NEs, the Ethernet ports of the NEs can be used to achieve the extended ECC communication. By default, the OptiX OSN 1800 series NEs take the auto-extended ECC communication. When the number of NEs that use the extended ECC communication exceeds nine, you must set the extended ECC communication to specified mode. 5.6 Configuring IP over DCC When the network planning adopts the IP over DCC mode for communication, you need to configure the DCC channel and check whether the IP routes are correct in the commissioning and configuration. 5.7 Configuring Board Parameters

Issue 02 (2010-09-30)


5-1



Different boards implement different functions, and therefore you need to configure different parameters in the commissioning and configuration for deployment. Set parameters appropriately for each board according to the actual network. 5.8 Creating Fibers You are recommended to create fibers in graphic mode in the Main Topology or signal flow view. 5.9 Configuring Cross-Connection Service The LQG and LQM2 boards support configuration of cross-connections and the methods of configuring cross-connections on the two boards are the same. By default, a cross-connection created on the LQG and LQM2 boards is a direct cross-connection. 5.10 Configuring Services in Service Package Mode The service package module enables you to configure services on an NE in a one-click manner. This configuration method is easier and quicker. The OptiX OSN 1800 supports two types of service packages: GE service package and GE/STM-1 integrated service package. The LQM, LQM2, and LWX2 boards support the function of configuring services in service package mode. 5.11 Configuring SW SNCP Protection SW SNCP protection can be implemented by using convergence OTU boards that support crossconnections. This type of OTU boards includes the LQM2 and LQG boards. 5.12 Configuring Port Protection On the port protection user interface, you can configure intra-board 1+1 protection, optical line protection, client-side 1+1 protection, and inter-subrack 1+1 optical channel protection. Configure protection of an appropriate type according to the network design. 5.13 Synchronizing the NE Time with the NMS Time With the time synchronization function, the NE time is kept consistent with the NMS time. In this way, the NMS is able to record the correct time when alarms and abnormal events are reported by NEs. 5.14 Starting NE Performance Monitoring Enabling the performance monitoring function is a precondition for querying the performance events. If the current NE time is in the performance monitoring time range as set before, the NE monitors its performance events automatically. If the performance monitoring time range is not set or if the current NE time is not within the performance monitoring time range, the NE does not monitor its performance events. 5.15 Searching and Creating WDM Trails After configuring services on an NE, search for WDM trails on the NE so that you can manage services based on WDM trails. 5.16 Checking Configurations in the Commissioning Process Correct setting of each system parameter is the precondition for ensuring normal network operation. 5.17 Backing Up the NE Database to the SCC Board By backing up an NE database to an SCC board, you can ensure that the NE automatically restores to the normal state in case a power failure occurs. When you back up an NE database to an SCC board, you actually back up the NE data to the flash memory of the SCC board. After a power-off reset occurs on the NE, the SCC board automatically reads the configuration data from the flash memory and applies the data to the boards on this NE. 5.18 Checking Optical Power of Boards By checking the optical power of a board, you can ensure that the transmit and receive optical power of the board is within the normal range. When commissioning the OptiX OSN 1800, you 5-2


Issue 02 (2010-09-30)



can adjust the optical power of a board at the site by adding, replacing, or removing a fixed optical attenuator (FOA) or adjusting a variable optical attenuator (VOA) before an optical interface. 5.19 Querying Bit Errors Before and After FEC The count of bit errors before and after FEC is a key specification for measuring the system operation quality. 5.20 Viewing Current Alarms on an NE and Removing Abnormal Alarms Viewing the current alarms on an NE helps you to intuitively and quickly locate an exception on the network. This helps you to identify a fault on the network. 5.21 Testing Protection Switching In the commissioning or configuration phase, you can run a manual switching command to check whether protection switching can be performed normally. 5.22 Querying and Saving the Networkwide Optical Power and Alarm Data After commissioning a network, you need to query and save the optical power and alarm data of the entire network. This type of data can help you analyze and understand the operating status of the network in future. 5.23 Backing Up NE Data to the NMS Server or Client You can manually back up the data of one or more NEs of the same type to an NMS server or client.

5.3 Changing the ID and Name of an NE The ECC protocol uses an NE ID to uniquely identify an NE. When planning the network, you must assign a unique ID for each NE. If an NE ID conflicts with another one, ECC routing collision is caused. In this case, certain NEs cannot be managed.

Prerequisite The NE communication must be normal. 5-8


Issue 02 (2010-09-30)




Precautions

CAUTION NE ID conflict leads to unreachable of NEs. Therefore, the ID of an NE must be unique on the network.

CAUTION If an NE is configured with the inter-subrack wavelength protection, you need to delete the protection before changing the NE ID and configure the protection again after changing the NE ID. NOTE

If the IP address of an NE is not changed before you change the NE ID, the IP address of the NE varies with the NE ID. Once the IP address of the NE is changed, the association between the NE ID and IP address is deleted automatically. TIP

If an NE is unreachable after the NE ID is changed, you can change the name of the NE only after searching for and logging in to the NE again. Therefore, you are recommended to change the NE name before changing the NE ID.

5.5 Configuring Ethernet Extended ECC When there is no OSC or ESC communication between two or more NEs, the Ethernet ports of the NEs can be used to achieve the extended ECC communication. By default, the OptiX OSN 1800 series NEs take the auto-extended ECC communication. When the number of NEs that use the extended ECC communication exceeds nine, you must set the extended ECC communication to specified mode.

Prerequisite The communication between NEs must be normal.


Background Information The extended ECC communication has the following two modes: l

Automatic mode: Extended ECC connections are established automatically. This mode is convenient but extra connections are established. Therefore, the resource utilization ratio is low and this mode is recommended to be used when the number of NEs is smaller than nine.

l

Specified mode: Extended ECC connections are established according to the specified server and client. In this mode, the connections are reliable and the bandwidth utilization ratio is high. In normal cases, use the specified mode to establish extended ECC connections. An NE cannot operate in both modes at the same time to establish extended ECC communication with another NE.

In the case of Ethernet extended ECC, a server NE can be connected to a maximum of eight client NEs and a client NE can serve as the server NE of another extended ECC group. Generally, set an NE that is not configured with the supervisory channel (ESC or OSC) as a client NE and an NE that is configured with the supervisory channel (ESC or OSC) as a server NE. You can set the ECC extended mode on site or remotely. When setting the ECC extended mode remotely, you need to set client NEs first and then server NEs under the condition that communication between NEs and the NMS is normal. When setting the ECC extended mode remotely, set an NE without the supervisory channel (ESC or OSC) first and then an NE with the supervisory channel (ESC or OSC). In the case of an NE without the supervisory channel, the NE is unreachable and communication between the NMS and the NE fails after the ECC extended mode is set remotely. The communication is restored automatically after an NE with the supervisory channel at the same station as the NE without the supervisory channel is set. For example, a station has ten NEs. The supervisory channel (ESC or OSC) is configured on NE A. Figure 5-1 shows the network topology. Table 5-1 provides the IP addresses of the NEs and the ECC setting plan. NE A is the server NE. NE I is a client NE of NE A and the server NE of NE J. 5-14

When setting the extended ECC communication mode at the station remotely, observe the following sequence: Issue 02 (2010-09-30)


5-15



J → I client → H, G, F, E, D, C, and B → A server → I server During the configuration, the status of the communication between the NMS and NEs changes frequently. l

After the setting on NE J is complete, the communication between the NMS and NE J fails.

l

After the setting on NE I client is complete, the communication between the NMS and NE I fails.

l

After the settings on NEs H, G, F, E, D, C, and B are complete, the communication between the NMS and NEs H, G, F, E, D, C, and B fails.

l

After the setting on NE A server is complete, the communication between the NMS and NEs B, C, D, E, F, G, H and I is restored automatically.

l

After the setting on NE I server is complete, the communication between the NMS and NE J is restored automatically.

Precautions

CAUTION When setting the ECC extended mode remotely, ensure that the configuration sequence is correct. That is, modify the ECC extended mode of opposite non-gateway NEs first and then the ECC extended mode of the gateway NE. Otherwise, the communication between the NMS and the unreachable NE cannot restore automatically. In this case, onsite resetting is required.

CAUTION Do not set the extended ECC mode for the communication between gateway NEs of subnets. In addition, you are recommended not to set a gateway NE but an NE closest to the gateway NE as a server NE.

CAUTION To ensure normal communication, the ECC extended mode of the NEs that adopt the Ethernet extended ECC communication must match. The match requirements are as follows: l If you set the ECC extended mode to automatic mode for an NE, you need to set the ECC extended mode also to automatic mode for the opposite NE. l If you set the ECC extended mode to specified mode for an NE, you need to set the ECC extended mode also to specified mode for the opposite NE. In addition, the two NEs must be of the client-server relationship. That is, if an NE serves as the server, the opposite NE must be the client. NOTE

When setting the ECC extended mode remotely, you are recommended to work out the ECC setting plan in advance to ensure that the settings are correct.

The LQM board supports slice services, such as GE_SLICE, FC100_SLICE, FC200_SLICE, FICON_SLICE, and FICON_EXPRESS_SLICE. Compared with common services, slice services feature better performance in transparent transmission of clock but require more timeslots. In practical application, select a proper service type according to the actual conditions. For example, when the LQM board is used to receive FC100 services, select FC100_SLICE if better performance in transparent transmission of clock is required and timeslots are sufficient. Otherwise, select FC100 so that more timeslots can be used to receive other types of services.

5.10 Configuring Services in Service Package Mode The service package module enables you to configure services on an NE in a one-click manner. This configuration method is easier and quicker. The OptiX OSN 1800 supports two types of service packages: GE service package and GE/STM-1 integrated service package. The LQM, LQM2, and LWX2 boards support the function of configuring services in service package mode.

Prerequisite You must have logged in to the NE where the LQM, LQM2, or LWX2 board resides. 5-70


Issue 02 (2010-09-30)




Background Information You can select the required service package during the deployment. Then, you can run the commands in the service package to configure services and query information the service package. You can run a command to manually apply a service package to an NE. In this manner, the services on all the service boards on this NE are configured automatically. In the process of applying a service package to an NE, the original configurations on the NE are deleted and the configuration commands are then executed. A service package actually contains a series of configuration commands. Some of these configuration commands are used for configuring crossconnections, and the other are used for configuring service types for optical interfaces. There is an exception that a service rate other than service type is configured for an optical interface in the case of the LWX2 board.

Precautions

CAUTION In the case of the LQM2 board, after the configuration commands in a service package are executed, a direct cross-connection between optical interface 3 and optical interface 4 is configured automatically. In the case of the LWX2 and LQM boards, the configuration commands in a service package cannot be used to create any cross-connection.

CAUTION Precautions for configuring services in service package mode l Service packages do not support expansion based on the existing services. If expansion is required, you need to delete the existing services before configuring services in service package mode. l In the process of applying a service package to an NE, the configurations on all boards on this NE are deleted and the service package is then implemented. l If the NE is reset in the process of configuring scripts, you need to restart the service package before you configure services.

CAUTION In the case of the LQM2 board, take the following precautions before configuring services in service package mode: l After configuring services in service package mode, if one of optical interfaces 3 to 6 on the LQM2 board needs to access another type of service, you need to reconfigure the service type manually for this optical interface. Otherwise, the service is unavailable. l If the current working mode of the LQM2 board is the 2LQM mode, the working mode of the board automatically changes to AP8 after service types are configured for the board in service package mode.

5.13 Synchronizing the NE Time with the NMS Time With the time synchronization function, the NE time is kept consistent with the NMS time. In this way, the NMS is able to record the correct time when alarms and abnormal events are reported by NEs.

Prerequisite You must have logged in to an NE.


Background Information When NEs report alarms and abnormal events to the NMS, the generation time of such alarms and events is based on the NE time. If the NE time is incorrect, the generation time of the alarms recorded in the NMS is also incorrect, which may cause troubles in fault locating. The same case happens to the generation time of abnormal events that are recorded in the NE security log. To prevent the preceding problem, the NMS provides the function of synchronizing the NE time with the NMS time to ensure that the NE time is correct. With this function, all NEs can be synchronized with the NMS time manually or automatically. In this manner, all the NEs use the NMS time as the standard time. The NMS server time refers to the time of the computer system where the NMS server resides. This function features easy operation and applies to a network with relatively low requirement for time accuracy. Synchronizing NE time with the NMS time does not affect the existing services. Before synchronizing the NE time with the NMS time, make sure that the time of the computer system where the Web LCT/T2000 server resides is correct. If you need to change the computer system time, first exit the Web LCT/T2000. Then, restart the Web LCT/T2000 after re-setting the computer system time. Issue 02 (2010-09-30)

Of these WDM trails, you can manage OTS trails directly without searching for them, because the OTS trail data is stored at the network layer when fibers are connected.

Precautions NOTE

In the process of searching and creating WDM trails, discrete services may be generated. You need to analyze and remove the discrete services to ensure that no discrete service exist on the network at last.

Procedure l

Operations on the T2000 For detailed description of searching, creating, and managing WDM trails, see the online help for the T2000. 1.

In the Main Menu, choose Trail > WDM Trail Search to display the WDM Trail Search navigation.

2.

In the Advanced settings area, set various handling policies associated with trail searching.

Click Next to start searching for WDM trails. Wait until the status bar shows the end of the searching. NOTE

l If certain cross-connections conflict with each other and thus fail to form an end-to-end trail, the information about these cross-connections is displayed in the search result when the searching is complete. You can rectify the problem according to the conflict information. l Certain cross-connections may conflict with each other when the network architecture is changed or a trail that may cause an interruption of service flows exists. You can determine whether conflicting cross-connections exist by deleting certain routing information such as deleting a cross-connection or a fiber

4.

Optional: Click Next to view the information about the conflicting trails. Right-click a trail, you can configure it with a management flag. NOTE

If you have selected Automatically create trails after searching in the search policies, skip this step. If you perform this step, the NMS will remove the trails that are not configured with management flags from the network in the next step. The deletion does not affect the actual services on the NE and the data of the NE saved on the NMS.

5.

Click Next to view all discrete services on the network. NOTE

The possible causes of discrete services and the method for removing discrete services are as follows: l The data on the NE is inconsistent with that on the NMS. In this case, upload the configuration data to the NMS. l Fibers are created inappropriately and the created fiber connections are inconsistent with the physical fiber connections. In this case, check and ensure that the fiber connections created on the NMS are consistent with the physical fiber connections between real equipment. l NE configuration data is incorrect and service configuration is incomplete. In this case, correct the NE configuration data and configure services completely.

5.18 Checking Optical Power of Boards By checking the optical power of a board, you can ensure that the transmit and receive optical power of the board is within the normal range. When commissioning the OptiX OSN 1800, you can adjust the optical power of a board at the site by adding, replacing, or removing a fixed optical attenuator (FOA) or adjusting a variable optical attenuator (VOA) before an optical interface.

Prerequisite The performance monitoring function must be enabled. Fiber connections must be established properly and lasers must be enabled.

Tools, Meters, and Materials The Web LCT or T2000 is used for querying the optical power of a board. The T2000 must be used for querying the optical power of the entire network.

Procedure l

Ensure that the input optical power value for each optical interface is in the range of Input Power Lower Threshold(dBm) and Input Power Upper Threshold(dBm). Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

Issue 02 (2010-09-30)



– If the input optical power value for an optical interface is greater than Input Power Lower Threshold(dBm), add a FOA or replace the existing FOA before the optical interface to ensure that the input optical power meets the design requirement. – If the input optical power value is smaller than Input Power Upper Threshold (dBm), do as follows: – Check the transmit optical power of the opposite board. If the transmit optical power of this board is abnormal, replace the transmitter on this board. – Check whether appropriate FOAs are installed on the link against the FOA installation table. – Check and clean the fiber endfaces and flanges on the ODF. – Check whether fiber jumpers are bent seriously or bundled too tightly. – If the attenuation of line fibers is excessive, recommend customers to rectify the line fibers or add an REG station to ensure that the actual line attenuation is smaller than the line attenuation specified in the design document. TIP

At the site, you can also use the following methods to determine whether the input optical power at an optical interface on a board meets the design requirement: l Use an optical power meter to measure the input optical power at an optical interface. Then, determine whether the input optical power is normal according to the permitted optical power range. l Check the status of the LED corresponding to this optical interface, such as IN, IN1, IN2, IN3, IN4, RM1, or RM2, on the front panel of the board. l Always on (red): indicates that the receive optical power is excessively low. l Blink (red): indicates that the receive optical power is excessively high. l Always on (green): indicates that the receive optical power is normal.

5.

Check the Output Power(dBm) value for each optical interface on the board. The value must be within the specified range. If the value for an optical interface is outside of the specified range, replace the optical module at the optical interface. For detailed specifications of a board, see the Hardware Description.

TIP

After right-clicking the title, select a parameter directly to hide or display it as required.

5.

Set Reference Working Upper Threshold(dBm) and Reference Working Lower Threshold(dBm). The T2000 compares the obtained Input Power(dBm) with the Reference Working Upper Threshold(dBm) and Reference Working Lower Threshold(dBm) values to determine whether the input optical power is normal. If Input Power(dBm) is in the range of Reference Working Upper Threshold(dBm) and Reference Working Lower Threshold(dBm), the input optical power is normal. If the input optical power exceeds either of the preceding thresholds by less than 2 dB, the Input Power State field is displayed as warning alert; if the deviation is greater than 2 dB, the input power state is displayed as critical alert. The Reference Working Upper Threshold (dBm) and Reference Working Lower Threshold(dBm) fields have no default values. If either of them is not set, the T2000 does not check for the input power state. NOTE

If the Input Power Reference Value(dBm) field is set but the Reference Working Upper Threshold(dBm) and Reference Working Lower Threshold(dBm) fields are not set, the T2000 automatically generates Reference Working Upper Threshold(dBm) and Reference Working Lower Threshold(dBm) field values according to Input Power Reference Value (dBm). In this case, the following formulas must be satisfied: l Reference Working Upper Threshold(dBm) = Input Power Reference Value(dBm) + 3dB l Reference Working Lower Threshold(dBm) = Input Power Reference Value(dBm) 5dB To ensure that the T2000 displays a correct power state, you are recommended to set the Reference Working Upper Threshold(dBm) and Reference Working Lower Threshold (dBm) fields.

In the case of the OptiX OSN 1800, the Reference Working Upper Threshold (dBm) and Input Power Upper Threshold(dBm) fields have the same value, and the Reference Working Lower Threshold(dBm) and Input Power Lower Threshold(dBm) fields have the same value. 6.

5-98

Check the value of the Input Power State field. If the field is displayed as Critical Alert or Warning Alert, it indicates that the optical power of the specified optical interface is outside of the normal range. In this case, proceed to analyze the problem. That is, rectify this problem in the same way as used to rectify such a problem by using the Web LCT.


Issue 02 (2010-09-30)



TIP

You can also compare Input Power(dBm) of each optical interface with Input Power Lower Threshold(dBm) and Input Power Upper Threshold(dBm). If the input optical power is outside of the range of Input Power Lower Threshold(dBm) and Input Power Upper Threshold(dBm), it indicates that the input optical power is abnormal.

7.

Set Output Power Reference Value(dBm). Output Power Reference Value(dBm) must be set according to the output optical power specification of the optical module at the specified optical interface. The T2000 compares the obtained Output Power(dBm) with the preset Output Power Reference Value(dBm) to determine whether the output optical power is abnormal. If Output Power(dBm) deviates from Output Power Reference Value(dBm) by less than 2 dB, the T2000 displays Output Power State as normal; if the deviation is 2 dB to 4 dB, the T2000 displays Output Power State as Warning Alert; if the deviation is greater than 4 dB, the T2000 displays Output Power State as Critical Alert.

8.

Check Output Power(dBm) for each optical interface on the board according to the value of Output Power State. The output optical power must be within the specified range. If the output optical power at an optical interface is outside of the specified range, replace the optical module at the optical interface. NOTE

Whether Output Power State is correct depends on an appropriate setting of the Output Power Reference Value(dBm). Thus, during the commissioning, set Output Power Reference Value(dBm) properly according to the specification of the board and determine whether the output optical power is normal.

9.

After customizing the optical power management template, save the template. In future, you can apply the template directly instead of re-setting parameters. To save the customized template, choose Filter by Template > Save As. In the displayed dialog box, enter the template name and then click OK. The Operation Result dialog box is displayed.

Set performance thresholds for a specified board

When an NE detects that a certain performance value exceeds the specified threshold, the NE reports a corresponding performance event. See this section to learn how to change a performance threshold of a specified board.

Set performance monitoring parameters of a board

The Web LCT/T2000 can monitor the performance of all boards on a network. The automatic reporting of detected performance values, however, is disabled by default. You can change the default setting as required.

Set performance monitoring parameters of an NE

Set the performance monitoring parameters of a specified NE properly and then enable the NE performance monitoring function. By doing so, you can obtain detailed description of performance records during the operation of the NE. This facilitates monitoring of the existing services and the equipment status.

Reset the performance register of a board

After a network test or fault recovery, you need to reset the performance register of a board as required before the board is put into operation. This is to start a new performance monitoring period.

Tools, Meters, and Materials Web LCT or T2000. When you need to view alarms on all NEs on the network, use the T2000.

Procedure l


In the NE Explorer window, select the NE and choose Alarm > Browse Alarms from the Function Tree. In the displayed window, click the Browse Current Alarms tab.

2.

Analyze and handle the reported abnormal alarms. In the case of on-site maintenance, handle Critical and Major alarms before handling other abnormal alarms. Analyze and handle alarms one by one according to the network situations. According to network conditions, certain alarms are reported inevitably, whereas certain alarms cannot be reported. For example, in general no service is accessed on the WDM side during deployment commissioning. In this case, relevant alarms are reported inevitably. These alarms, however, are cleared automatically after real services are accessed on the client side. In the commissioning and configuration phases of deployment, you need to analyze every reported alarm. In general, focus on the following alarms: – Optical power low or high alarm – Temperature threshold-crossing alarm – Abnormal communication alarm – Bit error-related alarm – Abnormal service alarm To handle a reported alarm, see the Alarms and Performance Events Reference.

A Handling Common Commissioning Problems

Handling Common Commissioning Problems

This chapter describes the methods of analyzing and handling the most common problems happening in the deployment process. You need to analyze and handle problems according to actual situations. In the commissioning or configuration phase of deployment, alarms are generally generated when a problem happens. For example, alarms are generated if no service is received on the client side or if the configuration is incomplete. You need to analyze each alarm reported by equipment to determine which alarms do not reflect abnormal running status and which alarms indicate running status in the current engineering conditions. Abnormal alarms must be handled properly in the commissioning or configuration phase of deployment. Equipment may report various alarms. Different alarms have different causes. This chapter describes the common causes of the common alarms and the common methods of handling such alarms generated during deployment. There may be other causes of such alarms. Thus, analyze and handle alarms in the commissioning or configuration phase of deployment according to actual situations. For details on how to handle alarms of the OptiX OSN 1800, see the Alarms and Performance Events Reference. When reporting an alarm, the NMS also displays the position where the alarm is generated. Determine the slot, board name, and optical interface where the alarm is generated according to the displayed position information. For example, 1-LDGF2-201(LP1/LP1)-OTU1:1. In the case of the LDGF2 board, 201(LP1/LP1) indicates the IN1 and IN2 optical interfaces, and 202(LP2/ LP2) indicates the IN3 and IN4 optical interfaces. The digit 1 at the end of the position information indicates the IN1 or IN3 optical interface. If the digit is 2, it indicates the IN2 or IN4 optical interface. That is, 1-LDGF2-201(LP1/LP1)-OTU1:1 indicates that the alarm is generated at the IN1 optical interface on the LDGF2 board in slot 1. The indication of the position information for other boards is similar.

A.1 The Receive Optical Power Is Normal But the LDGF Board Reports an OTU1_LOF Alarm Keywords LDGF, OTU1_LOF, LWX2 regeneration board

Symptom The receive optical power on the WDM side of the LDGF board is normal but the board reports an OTU1_LOF alarm. The LDGF board that reports an OTU1_LOF alarm works with the LWX2 regeneration board. Figure A-1 shows the network where the LDGF and LWX2 board are used. The ALS function of a laser on the LWX2 regeneration board is disabled and all lasers on this board are enabled. As shown in Figure A-1, the optical cable between the two LWX2 regeneration boards is unavailable. That is, the optical path between the two regeneration boards is absent. Thus, the downstream LWX2 regeneration board reports an R_LOS alarm. Figure A-1 LDGF board networking mode

L W X 2

L D G OUT1 F

Cause Analysis The receive optical power on the WDM side of the LDGF board is normal but the board reports an OTU1_LOF alarm. This indicates that the frame structure of the received optical signals is invalid or the board is faulty. In general, the probability that the board is faulty is very small. Thus, you can first check whether the received optical signals are normal. As described previously, the upstream optical path is unavailable, and thus the downstream LWX2 regeneration board cannot receive valid optical signals. The lasers on the downstream LWX2 regeneration board, however, are forcibly enabled. Thus, the downstream LWX2 regeneration board transmits white light signals that have no frame structure. Thus, although optical power of the optical signals received by the LDGF, the LDGF board reports an OTU1_LOF alarm because the received optical signals have no frame structure. A-2


Issue 02 (2010-09-30)



Procedure After an analysis, this is normal for the LDGF board to an OTU1_LOF alarm in the current engineering situation. When the optical cable between the two LWX2 regeneration boards is installed and the optical path between them are present, the OTU1_LOF alarm will be cleared automatically.

Reference Information None.

A.2 The Receive Optical Power Is Normal But the LDGF Board Reports a LINK_ERR Alarm Keywords LDGF, LINK_ERR

Symptom The receive optical power on the WDM side of the LDGF board is normal, the ETH port, however, reports the LINK_ERR alarm. No service gains access to the ETH port on the LDGF board where the alarm is reported.

Cause Analysis The LINK_ERR alarm indicates that valid links between two data ports fail to be established, however, the receive optical power on the WDM side of the LDGF board is normal and the line is normal. No service gains access to the ETH port on the LDGF board, and therefore valid links fail to be established and the LINK_ERR alarm is reported.

Procedure Under the current engineering condition, the situation is normal. 1.

If the ETH port on the LDGF board is planned to access services in the network planning, the alarm is cleared automatically after the ETH port accesses services normally.

2.

If the ETH port on the LDGF board is not planned to access services in the network planning, set the ETH channel to unused so that the channel does not detect the alarms that are irrelevant with normal network operation.

A.3 The Receive Optical Power Is Normal But the LWX2 Board Reports the R_LOC Alarm Keywords LWX2, R_LOC, interconnected equipment

Symptom The client side of the LWX2 board interconnects with the client equipment to access the STM-16 service. The optical interface of the client equipment reports the R_LOS alarm, the client side of the LWX2 board and the corresponding WDM side report the R_LOC alarm, and the service is unavailable.

Cause Analysis Check the optical power. The result shows that the receive optical power values on the client equipment and the client and WDM sides of LWX2 board are normal. Query the WDM interface attributes of the LWX2 board to check whether the board configuration is correct. The result shows that the service rates on the client and WDM sides of the LWX2 board are set to 2488.3 Mbit/s and 2667.0 Mbit/s respectively. Because the LWX2 board is a service transparent transmission board, the service rates on the client and WDM sides of the LWX2 board must be the same as the rate of the service that is actually accessed. Otherwise, the R_LOC alarm is reported and the service is unavailable.

Procedure The R_LOC alarm is reported because the service rate on the WDM side of the LWX2 board is different from the actual service rate. Change the service rate on the WDM side of the board to 2488.3 Mbit/s, and the symptom disappears and the service is available.

Reference Information Regardless of whether the LWX2 board is used as a service transparent transmission board or a regeneration board, the service rates on the client and WDM sides of the board must be the same as the rate of the service that is actually accessed. Otherwise, the service is unavailable.

Cause Analysis The REM_SF alarm indicates that the receive signals on the client side of the OTU board at the opposite station fail. At the deployment commissioning phase, no service gains access to the client side of the OTU board at station B, and therefore the alarm is reported.

Procedure After services gain access to the client side of the OTU board at station B, the alarm is cleared.


A.5 The Optical Path Is Reachable But the NE Cannot Be Logged in Remotely Keywords LDGF2, NE unreachable, remote login

Symptom The communication between stations A and B is achieved through only the ESC provided by the LDGF2 board. Because the optical fibers are not connected at the deployment commissioning phase, the optical paths of IN1/OUT1 on the LDGF2 board are unavailable. The optical paths of IN2/OUT2, however, are normal. See Figure A-3. Station B cannot be logged in remotely at station A. Issue 02 (2010-09-30)

A

Cause Analysis The LDGF2 board receives ESC overhead bytes through the channels of IN1/OUT1. The optical paths of IN1/OUT1 on the LDGF2 board are unavailable. Therefore, the ESC overhead bytes fail to be received, communication between NEs fails to be established, and the NE fails to be logged in remotely.

Procedure Under the current engineering condition, establish normal communication routes according to the network planning: l

Configure intra-board 1+1 protection on the LDGF2 boards at stations A and B respectively to establish normal communication between the two stations by using the channels of IN2/ OUT2.

l

Restore the fiber connections.

Reference Information In the case of the OTU boards with the dual fed and selective receiving function, before the protection is configured, overhead bytes are received through only the channels of IN1/OUT1 or IN3/OUT3. If the optical paths of IN1/OUT1 or IN3/OUT3 are unavailable, the ESC communication fails even if the optical paths of IN2/OUT2 or IN4/OUT4 are normal. After the protection is configured, the ESC communication is normal even if only one channel is normal.

Commissioning and Configuration This chapter lists the reference operations for the commissioning and configuration. You can perform proper operations according to the network condition. B.1 Obtaining NE IP Addresses at the Site In the case of onsite commissioning, if the T2000 or Web LCT is unavailable, you can obtain the IP address of an NE by running a command directly in the Windows operating system. B.2 Creating a Single NE Creating NEs one by one is not as quick and precise as the batch creation. However, creating NEs one by one is applicable no matter what way of communication an NE adopts. The NEs that use serial ports to communicate do not support the NE search function and you must create them one by one. B.3 Checking the NE Software Version This topic describes how to check the NE software version. B.4 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 Web LCT administrator is advised to create NE users before configuring services. B.5 Switching a Logged-In NE User During a new deployment, after the lct NE user creates an NE, this user can create another NE user. You can log in to the NE with the new NE user name. B.6 Modifying the Optical NE Name You can change the optical NE name at any time as required with no effect on the running of the NE. B.7 Modifying GNE Parameters During the network optimization and adjustment, you may need to change the GNE type or modify the communication address. B.8 Changing the GNE for NEs When the GNE that the non-gateway NE belongs to is changed and this non-gateway NE does not belong to another GNE, you need to change the GNE to maintain the communication between the NEs and the T2000.

This ensures that the SCC board of the NE automatically restores to normal operation after the NE data in the DRDB database of the SCC board is lost or a power failure occurs on the equipment. This section describes several NE data backup and restoration methods. You can select the method as required.

Comparison of Backup and Restoration Methods The locations for backing up and restoring the NE database include the SCC board, local server and remote server. Different storage locations determine different types of backup and restoration methods. See Table B-1. Table B-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 cold reset) on the SCC board, the SCC board reads the configuration from the DRDB (or flash) database. l after a warm reset on the SCC board, the MDB reads the configuration from the DRDB database. l after a cold reset on the SCC board, the MDB reads the configuration from the FLASH database.

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.

B-20


Issue 02 (2010-09-30)



NOTE

After the warm resets on other boards, the NE memory data is issued to the boards. When the actual configuration of the board is consistent with the configuration stored in the database for restoration, the process of delivering configuration data to the board does not interrupt services.

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

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.

l

DRDB: Dynamic random database. The data that is verified is automatically saved in the DRDB database. The data is lost when a power failure occurs but not lost after a warm reset is performed.

l

FDB: Flash database. There are the FDB0 and FDB1 databases. The data 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. The DRDB database is copied 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.

B.18.2 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.

Prerequisite l

You must log in to the NE as an NE user with system level authority.

l

The NE data from DRDB database must be backed up to the flash database on the SCC board.

Fault

A fault is the inability of a function to perform a required action. This does not include an inability due to preventive maintenance, lack of external resources, or planned actions.

Fiber connector

A device mounted on the end of a fiber-optic cable, light source, receiver, or housing that mates to a similar device to couple light into and out of optical fibers. A connector joins two fiber ends, or one fiber end and a light source or detector.

Fiber jumper

The fiber which is used to connect the subrack with the ODF.

H Hardware loopback

A method to use a fiber to connect the receiving optical interface with the transmitting one on a board. It performs transmission tests, which method usually does not require the assistance of personnel at the served terminal.

L Label

A mark on a cable, a subrack, or a cabinet for identification.

Laser

The device that generates the directional light covering a narrow range of wavelengths. Laser light is more coherent than ordinary light. Semiconductor diode lasers are the used light source in fiber-optic system.

Link

A "topological component" that provides transport capacity between two endpoints in different subnetworks via a fixed (i.e., inflexible routing) relationship. The endpoints are "subnetwork termination point pools" for SONET, and link termination points for ATM. Multiple links may exist between a pair of subnetworks. A link also represents a set of "link connections".

Loopback

The fault of each path on the optical fibre can be located by setting loopback for each path of the line. There are three kinds of loopback modes: No loopback, Outloop, Inloop.

M Multiplexer

An equipment which combines a number of tributary channels onto a fewer number of aggregate bearer channels, the relationship between the tributary and aggregate channels being fixed.

N NE database

The database that is saved in the SCC board. There are three types of databases on the SCC board as follows: (1) DRDB: a dynamic database in a dynamic RAM, powered by battery; (2) SDB: a static database in a power-down RAM; (3) FDB0, FDB1: permanently saved databases in a Flash ROM. In efficient operation, the NE configuration data is saved in DRDB and SDB at the same time. Backing up an NE database means backing up the NE configuration data from SDB to FDB0 and FDB1.

Network segment

The range of IP addresses in which the gateway NE will operate.

O OADM

A major separate area of a window or dialog box, usually used for display rather than data entry.

Path

A logical connection between the point at which a standard frame format for the signal at the given rate is assembled, and the point at which the standard frame format for the signal is disassembled.

PIN

Photodiode. A semiconductor detector with an intrinsic (i) region separating the p- and n-doped regions. It has fast linear response and is used in fiber-optic receivers.

Pointer

An indicator whose value defines the frame offset of a virtual container with respect to the frame reference of the transport entity on which it is supported.

Power box

A direct current power distribution box at the upper part of a cabinet, which supplies power for the subracks in the cabinet.

Procedure

A generic term for an action.

Process
