3.4 DS1-14 and DS1N-14 Cards
The ONS 15454 DS1-14 card provides 14 Telcordia-compliant, GR-499 DS-1 ports. Each port operates
at 1.544 Mbps over a 100 ohm twisted-pair copper cable. The DS1-14 card can function as a working or
protect card in 1:1 protection schemes and as a working card in 1:N protection schemes.
The DS1-14 card supports 1:1 protection. The DS1-14 can be a working card in a 1:N protection scheme
with the proper backplane EIA and wire-wrap or AMP Champ connectors. You can also provision the
DS1-14 to monitor for line and frame errors in both directions.
You can group and map DS1-14 card traffic in STS-1 increments to any other card in an ONS 15454
except DS-3 cards. Each DS-1 is asynchronously mapped into a SONET VT1.5 payload and the card
carries a DS-1 payload intact in a VT1.5. For performance monitoring purposes, you can gather
bidirectional DS-1 frame-level information (loss of frame, parity errors, cyclic redundancy check [CRC]
errors, and so on).
