Configure Optical Amplifier Module and Protection Switching Module and troubleshoot module-related operations.
Clear the card configurations
Use this procedure to clear card-level, OTS controller, and optics controller configurations before you replace a configured optical module with a different module type.
Optical amplifier module
Describes the NCS1K-EDFA optical amplifier module, including preamplifier and booster functions, OSC support, OCM monitoring, front-panel callouts, controller-to-port mappings, and COM-CHECK safety behavior.
In-line amplifier
This topic describes how in-line amplifier mode uses the pre-amplifier path, disables the booster path, and reports port power values for supported NCS 1001 slots.
Gridless OCM support
This topic describes gridless OCM support for flexible channel widths, PSD-based amplifier gain calculation, channel-width limitations, and command examples for supported widths.
Enable automated OTS-OCH thresholds on an amplifier
Use this task to complete the required CLI configuration for automated OTS-OCH thresholds on an amplifier and confirm that the intended NCS 1001 behavior is available after the changes are committed.
Protection switching module
This topic describes the NCS1K-PSM protection switching module, including TX and RX switching functions, front-panel callouts, protected and working path ports, and controller-to-port mappings.
Configure rx-low threshold for PSM
Use this task to configure the correct rx-low threshold procedure for a PSM working or protected RX port based on manual or automatic amplifier control mode.
PSM virtual photodiode
This topic describes how the PSM virtual photodiode calculates COM-RX power from available transmit photodiodes and reports fallback values when both related ports are unavailable.
PSM three-way protection
This topic describes the three-way protection topology formed by combining section and path protection, including threshold recommendations and limitations for switching behavior.
PSM revertive switch
This topic describes how PSM revertive switching returns traffic to the primary path after a fiber cut clears and explains WTR and threshold hysteresis behavior.
Optical service channel
This topic describes the optical service channel wavelengths and the traffic types carried for UDC ports and remote management on the NCS 1001.
Configure remote management
Use this task to configure OSC interfaces and static routes so that local and remote NCS 1001 nodes can be managed across OSC links.
Configure network topology discovery
Use this task to configure OSPF routes and verify routing table entries so compatible NCS 1001 nodes can be discovered across OSC links.
Network troubleshooting commands
This topic provides information about common management and OSPF routing issues with the commands used to check interface state, static routing, subnets, passive interfaces, and learned routes.
