Item
Description
Protection Groups
Lists the protection groups that have been created on the node.
Selected Group
Displays the slot and cards that are in the protection group and their protection status, either Protect or Working.
Switch Commands
(Available only when a protection group is selected.) Manages protection group switch commands:
Clear—Clears a traffic switch on the card or port highlighted under Selected Group.
Switch—1:1 protection groups only) Switches traffic from the highlighted working card or port to the protect card or port.
Manual—(1+1, splitter, and Y-cable protection groups only) Initiates a manual switch on the selected port. This command switches traffic only if the path has an error rate less than the signal degrade (SD) bit error rate (BER) threshold.
Force—(1+1, splitter, and Y-cable protection groups only) Initiates a forced switch on the selected port. This command switches traffic even if the path has SD or signal fail (SF) conditions. A Force switch has a higher priority than a Manual switch.
Inhibit Switching
(Available only when a protection group is selected.) Manages protection group lockout commands:
Unlock—Clears a lockout.
Lock Out—Prevents traffic from being switched to the card. Lockouts can only be applied to protect cards (in 1+1, splitter, and Y-cable configurations) and prevent traffic from switching to the protect port under any circumstance. Lockouts have the highest priority.
Lock On—Locks traffic onto the working card, that is, prevents a traffic switch from occurring. In a 1+1 configuration, you can also apply a lock-on to the working port. A working port with a lock-on applied cannot switch traffic to the protect port in the protection group (pair). For splitter and Y-cable protection groups, CTC allows a lock-on for a protect port if other switch conditions (Manual, Force) exist. Lock-on is not available if the protect port already has a lockout or lock-on present.
