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.
