In tributary SNCP (Subnetwork Connection Protection), the cross-connect granularity is not “GFor Any.” Instead, it is more granular, typically at the service or board level. (D) is false because SNCP protection requires specific configurations to selectively protect client services, using dual-fed and selective receiving functions in electrical cross-connections. Trigger conditions include board detection failures, SF (Signal Fail), and SD (Signal Degrade) occurrences. HCIP-Transmission details these conditions and protection mechanisms, emphasizing the precise granularity and protection scope of tributary SNCP.

R_LOS, R_LOF, R_OOF, and MUT_LOS all indicate loss of signal or framing, which directly interrupts service delivery.

The core component of a ROADM (Reconfigurable Optical Add-Drop Multiplexer) is indeed the Wavelength Selective Switch (WSS). The WSS enables dynamic selection and routing of optical wavelengths without converting them to electrical signals. It provides the flexibility to add, drop, or pass through wavelengths, allowing on-demand network reconfiguration. This capability supports agile wavelength management, crucial for modern elastic and automated optical networks. HCIP-Transmission documents emphasize that the WSS is the essential element that makes ROADMs programmable and adaptive, forming the backbone of flexible optical layer management.

Static LAGs use manual configuration and do not require LACP; LACP is only needed for dynamic link aggregation groups.

In the OTN hierarchy, the OTUCn layer provides digital section functions (framing, section monitoring, forward error correction), and the ODUCn layer provides the digital path (channel) functions, so together they implement the digital section and channel layers.

For the TMK1TDC board, intra-board electrical cross-connections must be configured to properly route signals within the board for correct service processing.

In Link Aggregation Group (LAG) settings, port priority determines which ports carry traffic preferentially. (A) If a primary port is configured to preferentially carry services, it must have a higher priority than other ports to ensure it is selected first. Port priority is numerically represented, and (D) a lower value of “port priority” means higher priority, which can be counterintuitive but is standard in networking. For manual aggregation groups that don’t run LACP, priority settings typically do not apply. This priority mechanism helps optimize link utilization and failover in aggregated links, as detailed in HCIP-Transmission documentation on Ethernet and service aggregation.

FDI (Forward Defect Indication) and BDI (Backward Defect Indication) are specifically defined to suppress alarms at the far end when a defect is detected, preventing redundant alarm cascades. CC and AIS do not perform alarm suppression.
