Chapter 7 Card Protection
7.1.1 1:1 Protection
7.1.1 1:1 Protection
In 1:1 protection, a working card is paired with a protect card of the same type. If the working card fails,
the traffic from the working card switches to the protect card. You can provision 1:1 to be revertive or
nonrevertive. If revertive, traffic automatically reverts to the working card after the failure on the
working card is resolved.
Figure 7-1
shows an example of the ONS 15454 in a 1:1 protection
configuration. Each working card in an even-numbered slot is paired with a protect card in an
odd-numbered slot: Slot 1 is protecting Slot 2, Slot 3 is protecting Slot 4, Slot 5 is protecting Slot 6,
Slot 17 is protecting Slot 16, Slot 15 is protecting Slot 14, and Slot 13 is protecting Slot 12.
