cross-connect states with one exception. A cross-connect in the Unlocked-disabled,automaticInService
service state cannot transition autonomously into the Unlocked-enabled service state until the parent port
is in the Unlocked-enabled service state.
You cannot transition a port from the Unlocked-enabled service state to the Locked-enabled,disabled
state. You must first transition the port to the Locked-enabled,maintenance state. Once a port is in the
Locked-enabled,maintenance state, the NODE.general.AllowServiceAffectingPortChangeToDisabled
default setting of TRUE allows you to put a port in Locked-enabled,disabled even if the following
conditions exist:
•
