Effect on MSP ring protection when an NE is powered off

Effect on MSP ring protection when an NE is powered off:
If an NE with space-division and time-division cross-connections (for example, VC-4:1 cross-connects to VC-4:2, or VC-4:1 to VC-12:1 cross-connect to VC-4:1 to VC-12:2) is powered off, the space-division and time-division cross-connection services that pass through this NE will be interrupted.
