3.2.3 EC1-12 Hosted by XCVT, XC10G, or XC-VXC-10G

All 12 STS-1 payloads from an EC1-12 card are carried to the XCVT, XC10G, or XC-VXC-10G card
where the payload is further aggregated for efficient transport. XCVT cards can host a maximum of
288 bidirectional STS-1s. The XC10G and XC-VXC-10G cards can host up to 1152 bidirectional
STS-1s.

3.2.5 EC1-12 Port-Level Indicators
You can obtain the status of the EC1-12 card ports by using the LCD screen on the ONS 15454 fan tray.
Use the LCD to view the status of any port or card slot; the screen displays the number and severity of
alarms for a given port or slot.
3.3 DS1-14 and DS1N-14 Cards
For hardware specifications, see the
Note
page
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. Each DS1-14
port has digital signal cross-connect frame (DSX)-level outputs supporting distances up to 655 feet (200
meters).
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 (LOF, parity errors, cyclic redundancy check [CRC] errors,
and so on).
OL-9217-01
describes the three card-level LEDs on the EC1-12 card.
EC1-12 Card-Level Indicators
Description
The red FAIL LED indicates that the EC1-12 card processor is not ready.
Replace the unit if the FAIL LED persists.
The green ACT LED indicates that the EC1-12 card is operational and ready
to carry traffic.
The amber SF LED indicates a signal failure or condition such as loss of
signal (LOS), loss of frame (LOF) or high BER on one or more card ports.
