1.1 Creating NEs

Creating an NE manually

Application scenario: The creation is accurate and fast. The ID of the target NE is known. You need to focus

only on the target NE.

Disadvantages: You need to know the ID of the target NE in advance. Only one NE can be created at a

time.

Application scenario: You have obtained the NE ID and the number of NEs to be created is not too large.

Creating NEs in batches by searching

Advantages: You do not need to know the NE ID in advance. Multiple NEs can be created at a time.

Disadvantages: The search takes some time. The larger the network scale is, the longer time the search

takes.

Application scenario: The NE ID cannot be obtained in advance. A large number of NEs need to be created.

1.2 (Optional) Creating an Optical NE (1/2)

NCE manages WDM NEs in two ways, independent NEs in the Main Topology and affiliate NEs in

optical NEs.

Optical NE type

WDM_OTM: optical terminal multiplexer

WDM_OLA: optical line amplifier

WDM_OADM: optical add/drop multiplexer

WDM_OEQ: optical equalizer

1.4 Configuring the Board Port Attributes (1/3)

You need to pay attention to a large amount of data when configuring the board data.

For OTU boards, you need to focus on the following points:

The laser status should be Enable when the board is in use or being commissioned.

The ALS function must be disabled forcibly during the commissioning.

Set the interface parameters of WDM boards according to the engineering requirements. Different

boards support different parameters, but the configuration procedures are the same. You can also

query all interface parameters.

1.5 Creating a Fiber (1/5)

To configure services, you must create fibers between NEs and between boards on an NE on NCE.

Before creating a fiber, you are advised to set Planned Wavelength No./Wavelength (nm)/Frequency (THz)

of ports of the tunable OTUs to the planned wavelength.

Methods of creating fiber connections

Creating fibers in the synchronization mode: After device commissioning is complete, fiber connection

information may already exist on the NE. You can synchronize the fiber connection information from the NE

to NCE.

Manually creating fibers in graphic mode: Fiber connections are created in the Main Topology or signal

flow diagram. This mode is applicable to the scenario where you need to create a large number of fibers one

by one.

Manually creating fibers using a list: In the Fiber/Cable Management window, you can manage all inter-

NE and intra-NE fiber connections in a unified manner. Compared with creating fibers in the graphic mode,

creating fibers using a list is not visualized. This mode is applicable to the scenario where a small number of

fibers need to be created.

1.8 NE Database Backup (1/3)

Methods of backing up the NE database

Backing up the NE database to the control board: The method is used when the control board is not

configured with a CF card and NE data in the DRDB database will be backed up to the FLASH memory. After a

power failure, the control board automatically reads configuration data in the flash memory and delivers it to

other boards. By default, NCE automatically backs up the NE database to the flash memory every 30 minutes.

Backing up the NE database to a CF card: When the control board is configured with a CF card, you can

back up the NE data in the DRDB database of the control board to the CF card, ensuring that the system can

be automatically restored after the data in the DRDB database of the NE control board is lost or the NE is

powered off.

Backing up NE data to the NCE server or client: This method is used for manually backing up the NE data.

You can manually back up the data of one or more devices of the same type to the NCE server or client at the

same time. The prerequisites are as follows: The backup directory has been specified, the FTP, TFTP, or

SFTP server has been configured, and the FTP, TFTP, or SFTP service is running.
