l Configure overheads at the OCh overhead management-SONET interface. l Configure OTS overheads at the OCh overhead management-OTN interface.
WDM Service Configuration
At an optical add/drop multiplexer (OADM) station, you can configure ADM for GE/FC services by using the LQG, LOG, and other boards.
l Configure several WDM service boards in specified slots to form a cross-connect board group.
l Enable the add/drop, pass-through, and loopback functions for GE services in each cross- connect board group.
l Configure wavelength cross-connection protection (WXCP), with working and protection cross-connections configured on the sink NE.
Configure electrical cross-connections. The Web LCT allows you to configure electrical cross- connections to control service flow at the electrical layer. In this manner, the networking capability and network survivability are greatly enhanced.

l Implement distributed grooming based on GE services, ODU1 and ODU2 services and Any services.
Deploy the ODU3, ODU2, ODU1, ODU0, and GE services, Any services, and OTU1 cross- connections, and configure unidirectional and bidirectional SNCP at the ODU0, ODU1, ODU2, and ODU3 levels.
Configure optical cross-connections.
l Create OCh cross-connections dynamically and manage optical cross-connections on boards and NEs including creation, activation, deactivation, deletion and query. l Create edge ports.
Manage services.
l Lock WDM trails and the lock status is reflected in the service management window of NE Explorer.
l View the name of the trail that a service belongs to.
l Query the involved trails from services.
ROADM Configuration
By using the reconfigurable optical add/drop multiplexer (ROADM) function, you can perform add/drop and pass-through configurations for optical channels.
Configure ROADM based on the WSS. This mode applies to cross-connect nodes in a ring to groom multi-dimensional optical cross-connections. A maximum of eight dimensions are supported.
Optical cross-connection broadcast services: Support the broadcast services of optical cross- connections on a per-NE basis.
WDM Protection Configuration
You can perform the following operations on the Web LCT: l Configure inter-subrack protection.
l Configure port protection, including: – Configuring optical line protection
– Configuring intra-board 1+1 protection: This function includes the intra-board 1+1 protection realized by the dual-fed OTU board and the intra-board 1+1 protection realized by the DCP or OLP board

Optical Power Adjustment
l Manage the optical power: Query the input power, output power, and power thresholds of each WDM board.
l Perform intelligent power adjustment (IPA): In the case of a fiber cut, the optical amplifier board detects signal loss at the local station. The local station reports an event to the Web LCT. After the event is confirmed, the optical amplifier boards at the upstream and downstream stations reduce their output power to a safe value to protect fiber maintenance engineers from being injured by the laser emitted from the cut fiber. After the fiber is reconnected, the optical signals are restored and the optical power of each optical amplifier board automatically returns to a normal value.
l Configure pre-alerts for optical power at ports.
Dispersion Compensation
l This function supports 40G dispersion compensation configuration. It uses the TDC to precisely adjust the dispersion.
WDM PRBS
You can perform PRBS on a board to check the path quality. You can also check whether the WDM link functions properly before provisioning a service.
