- Executing the LoP (Lock Out of Protection Command) – for both the 1+1 and 1:N Protection Architectures
- What does the LoP Command do to the Protection Group?
- How do we Implement this Command?
- How do we Terminate this Command (to resume Normal Operation)
- Executing the Force Switch – Normal Traffic Signal to Protection (for the 1+1 Protection Architecture)
- How does this command’s execution affect the Protection Group’s operation?
- How do we Implement this Command?
- Implementing the Force Switch – NULL Test Signal to Protection Command – to resume Normal Operation.
- Executing the Force Switch – Normal Traffic Signal n to Protection (for the 1:N Protection Architecture)
- How does this command’s execution affect the Protection Group’s operation?
