DS1-14 and DS1N-14 Cards
3.4.1 DS1N-14 Features and Functions
The DS1N-14 card supports the same features as the DS1-14 card in addition to enhanced protection
schemes. The DS1N-14 is capable of 1:N (N<
5) protection with the proper backplane EIA and wire-wrap
or AMP Champ connectors. The DS1N-14 card can function as a working or protect card in 1:1 or 1:N
protection schemes.
3.4.2 DS1-14 and DS1N-14 Slots and Connectors
You can install the DS1-14 card in Slots 1 to 6 or 12 to 17 on the ONS 15454. Each DS1-14 port has
DSX-level (digital signal cross-connect frame) outputs supporting distances up to 655 ft.
If you use the DS1N-14 as a standard DS-1 card in a 1:1 protection group, you can install the
DS1N-14 card in Slots 1 to 6 or 12 to 17 on the ONS 15454. If you use the card’s 1:N functionality,
you must install a DS1N-14 card in Slots 3 and 15. Each DS1N-14 port features DSX-level outputs
supporting distances up to 655 ft depending on facility conditions.
