It is forbidden to modify the system time of the server during the T2000 operation. Please set the system time during the T2000 installation. To modify the system time of the server, do exit from the T2000 server first and then restart it after the modification.

Do not modify the name and IP address of the computer as T2000 server randomly.

Log in the Solaris CDE as t2000 on the UNIX platform. While on the Windows platform, you must use the user name and password in the T2000 installation for login.

Make sure the data at NE side is consistent with that at the NM side. When the NE data configuration is finished and runs normally, please update the data at the NM side manually or with auto synchronization function.

Backup the T2000 database periodically to minimize the loss caused by system abnormity.

If the login user has the authority of system administrator, the operation of “Shut Down Server” can be implemented. Be cautious to execute this operation to avoid shutting down the running server by mistake.

It is recommended to query the latest data from the NE side before settings parameters.

Usually, when a dangerous operation is going to be implemented, the T2000 will give a confirmation message to remind the operator.

2 Creating Topology

This chapter introduces how to create topology objects in the T2000 screen. This is the first step in configuration.

The following tasks are described:

Creating NEs

Creating Topology Subnet

Changing Subrack NE Attributes

Creating Optical NE Attributes

Creating Links

Creating NM



2-2

2.1 Creating NEs

There are several ways to create NEs.

2.1.1 Searching NEs in Batch

Purpose

It is to search for the NE ID information of all NEs in a network and the IP addresses of the gateway NEs by specifying the IP address range of a network to be searched.

Based on the above information, you can create NEs in batch on the T2000 and display them on the Main Topology. The equipment search function of the T2000 can also be used to search for and display the information about connection between NEs, but you need to manually create these fibers/cables one by one.

Searching for and creating NEs in batch is quicker and more accurate than manually creating NEs one by one. This method applies to the situation that data has been configured on the NE side and fiber/cable connection has been established between NEs.

Prerequisite

NM user with the authority of "system maintainer" or above.

Procedure

Step Action

1 Select [Topology/Automatic Equipment Detection] from the Main Menu.

Prerequisites


Procedure







7-8

Step Action 4 Right-click a clock source and select the switching operation.

Note:

To switch the currently traced clock source, make sure the new clock source is of good quality, exists in the corresponding priority table and is not locked. Manual switching is different from forced manual switching. Manual switching must meet these conditions: 1) The source to be manually switched to must exist in the corresponding priority table and cannot be locked. 2) When the SSM protocol is enabled, the SSM priority of the source must be the highest. 3) In addition, manual switching is only used in the case when no priority table is used and its switching priority is lower than that under any other switching conditions, such as source status change, SSM message degradation, forced switching operation and locking operation.

9.4 IPA Management

WDM system provides the IPA (Intelligent Power Adjustment) function.

In case the optical power signals on one or more segments of the active optical path are lost, the system can detect the loss of optical signals on the link and instantly reduce the optical power of the amplifier to a safety level. It will reduce the optical power of all amplifiers in the regeneration section of the downstream. When the optical signals of the system are recovered, the normal working of the optical amplifier can be recovered. The loss of optical signals might be caused by broken optical fiber, equipment deterioration or connector disconnection.

Note:

In the DWDM system, the IPA function is started only when optical signals of the active optical path are lost. When this function is executed, the objects of monitoring and shut-down action are both in service path. No operation will be implemented on the optical supervisory channel. Hence the functions of all optical supervisory channels will not be affected.

This section introduces the configuration of IPA. IPA configuration contains:

Create IPA

Set Delay Time for IPA

9.5 ALC Management for 1600G/320GV3

In DWDM system, optical fiber aging, optical connector aging or manual factors might lead to the abnormal attenuation of transmission lines. In case the attenuation on a line segment increases, all input and output power will be reduced on all downstream amplifiers. The system OSNR will get worse. At the same time, the received optical power will also be reduced. Receiving performance will be greatly affected. The closer the attenuated segment is to the transmission end, the more influence on OSNR there will be, as shown in Figure 9-1.

If the automatic level control (ALC) function is activated, this effect can be minimized. As the attenuation on a line segment is increased, the input power on the amplifier will be reduced. But due to ALC, the output power as well as the input and output powers of other downstream amplifiers will not be changed. Hence there will be much less influence on OSNR. The optical power received by the receiver will not be changed. Figure 9-2 shows the power changes on optical line amplification regenerators in the gain control and power control modes in case of abnormal attenuation on optical fiber lines.

Configure the ALC Protocol Channel

Create the ALC Link Node

Check the ALC Link

Search the ALC Link

Start/Stop Automatic Link Adjustment



9-16

9.5.1 Configuring the ALC Protocol Path

Purpose

Use this procedure to create a physical channel for transmission of ALC link protocol.

Prerequisite


Procedure

Step Action 1 Select [Maintenance/ALC Management] from the Main Menu.

2 Select “1600G/320GV3 Protocol Path Configuration” tab in the bottom pane.

3 Select an NE from the “NE Name” list in the bottom pane, and right-click in the idle area to select “Set Protocol Channel". “Set ALC Protocol Channel” dialog box is displayed.

4 Set the West Supervisory Channel and the East Supervisory Channel for this NE.

5 Click <OK>.

9.5.2 Creating the ALC Link Node

Purpose

The units involved in the ALC function and their functions are:

Optical amplifier unit (such as OAU, OBU): detect optical power

Variable optical attenuation (such as VOA): adjust optical power

Optical spectrum analysis unit (such as MCA): detect the number of channels

Optical supervisory channel unit (such as SC1/SC2/TC1/TC2): support transmission channel for ALC protocol.



9-17

Control and communication unit (such as SCC/SCE): support control function for ALC.

Use this procedure to create the ALC nodes along the link.

Note:

There are two working modes of ALC: wave detection mode and power reference mode.

ALC cannot be enabled if the link is not properly configured. Pay attention to the following:

The ALC link number ranges from 1 to 255. Repetition of link number is not allowed. A subrack can be configured with four links at most.

The nodes on the same link must have the same direction.

The ALC node number must start from 1, and then increase consecutively along the service direction.

An MCA node is a node configured with MCA board specially for monitoring the ALC link. An ALC link can only be monitored by one optical port of one MCA board of an MCA node, and this optical port can monitor one ALC link only.

The nodes not involved in the ALC adjustment can be configured as pass-through nodes. The pass-through node is neither the first nor the last node, and cannot be a MCA node.

When setting an ALC link in the power reference mode, pay attention to the following:

The system supports one ALC link being divided into multiple power control sections to accommodate OADM application.

The initial node or the start node of a new power control section has no corresponding power reference. To ensure the correctness of the output power at the reference node, it is required to set a standard gain and check the actual gain of the reference node. When the actual gain of the reference node changes, it is necessary to reset the standard gain.

The auto adjustment switch is set at the initial node only in the power reference mode. It is suggested to be enabled after the whole ALC line works normally.

In the power reference mode, the reference node configured must be located upstream of this node, and the initial node takes itself as the reference node. If the ALC link passes through an OADM station with service add/drop operation, it is necessary to reset a new reference node in the new power control section. You can configure it on the same ALC link, or establish a new ALC link.



9-18

Prerequisites


For the number-of-channels detection mode, the MCA board has been created in the ALC link.

9.7 Fiber Power Check

Purpose

In the application of the OptiX Metro 6100 system, either of fiber aging, optical connector aging or human factors may cause abnormal attenuation to the line. When the line attenuation decreases, as the optical power of the receive end has redundancy, the decrease of the optical power has little effect on the receive end. However, the input optical power downstream will decrease, thus severely affecting the OSNR of the system. In the end, the downstream will receive no signal.

To avoid this situation, the fiber link detection function is added to the T2000, which can regularly detect the optical power attenuation of every line. When it finds that the attenuation change of a line exceeds the predefined threshold, an abnormal event is generated in the T2000, prompting you to adjust the attenuation value of the VOA until the line attenuation of the entire ring is restored to normal.

Use this procedure to configure the fiber power check function.

Prerequisites

Boards with the optical power detection function have been created.

9.8 Automatic Optical Power Equalization

The automatic power equilibrium (APE) function can automatically adjust optical power of each channel at the transmitting end, so as to optimize the OSNR at the receiving end.

The APE function is implemented by MCA, V40/V32, SC1/SC2 and SCC. Their networking is shown in Figure 9-3.

Adjustment station Monitoring station

V40

OAUMCA

SC1

Figure 9-3 Networking for APE function

The normal functioning of APE requires the coordination between the optical boards and the SCC board, and the participation of the user. As shown in Figure 9-3, for power equilibrium, each channel power at the transmitting end can be adjusted according to the per channel power measured by the MCA at the receiving end. The APE brings convenience to DWDM system test in deployment and subsequent network maintenance. The APE function mode can also be set allowing user to decide whether to adjust the optical power.

Configuration principle:

To implement the APE function, it is required that the OTM station at the transmitting end should be configured with V40/V32, and the OTM station at the receiving end should be configured with MCA. Moreover, since DWDM is a dual-fiber bidirectional system, an MCA should be configured at the both ends of a multiplexing section.

To implement the APE function, it is required to install MCA and OSC unit (SC1/SC2/TC1/TC2) in one subrack. If not, network port ETHERNET 2 of two subracks should be interconnected.
