The DS3-12E supports a 1:1 protection scheme, meaning it can operate as the protect card for one other
DS3-12E card.
The DS3N-12E can operate as the protect card in a 1:N (N <= 5) DS3 protection group. It has additional
circuitry not present on the basic DS3-12E card that allows it to protect up to five working DS3-12E
cards. The basic DS3-12E card can only function as the protect card for one other DS3-12E card.
3.9.1 DS3-12E and DS3N-12E Slots and Connectors
You can install the DS3-12E and DS3N-12E cards in Slots 1 to 6 or 12 to 17 on the ONS 15454. Each
DS3-12E and DS3N-12E port features DSX-level outputs supporting distances up to 137 meters
(450 feet). With the proper backplane EIA, the card supports BNC or SMB connectors. See the
“7.2 Electrical Card Protection and the Backplane” section on page 7-5
for more information about
electrical card slot protection and restrictions.
