7.6 Converting DS-1 and DS-3 Cards From 1:1 to 1:N Protection
The ONS 15454 provides three protection options for DS1-14 and DS3-12 cards: unprotected, 1:1, and
1:N (N=5 or less). Changing protection from 1:1 to 1:N increases the available bandwidth because two
of the three cards used for protection in the 1:1 protection group become working cards in the 1:N group.
1:N (N=5 or less). Changing protection from 1:1 to 1:N increases the available bandwidth because two
of the three cards used for protection in the 1:1 protection group become working cards in the 1:N group.
When setting up 1:N protection, install the DS1N-14 or DS3N-12 card in Slot 3 or 15 on the same side
of the ONS 15454 as the cards it protects. Slot 3 protects cards in Slots 1 - 2 and 4 - 6. Slot 15 protects
Slots 12 - 14 and 16 - 17. A DS1N-14 or DS3N-12 card installed in Slot 3 or 15 can protect up to five
DS1-14 or DS3-12 cards. If you install a DS3N-12 or DS1N-14 card in another slot, it behaves like a
normal DS-1 or DS-3 card.
