DS3XM-6
DS3XM-12
DS3/EC1-48
Pairs one working card with one protect card. The protect card
should be installed in an odd-numbered slot and the working
card in an even-numbered slot next to the protect slot towards the
TCC2/TCC2P, for example: protect in Slot 1, working in Slot 2;
protect in Slot 3, working in Slot 4; protect in Slot 15, working
in Slot 14. 1:1 protection can be revertive or nonrevertive. For
more information, refer to the “Card Protection” chapter in the
Cisco ONS 15454 Reference Manual.
1:N DS1N-14
DS3N-12
DS3N-12E
DS3XM-12
DS3/EC1-48
Assigns one protect card for several working cards. The
maximum is 1:5. Protect cards must be installed in Slot 3 or 15
and the cards they protect must be on the same side of the shelf.
Protect cards must match the cards they protect. For example, a
DS1N-14 can only protect DS1-14 or DS1N-14 cards. If a failure
clears, traffic reverts to the working card after the reversion time
has elapsed. For more information, refer to the “Card Protection”
chapter in the Cisco ONS 15454 Reference Manual.
