4.14 4.13.1 OC48 ELR 200 GHz Card-Level Indicators

The OC48 ELR 200 GHz cards support extended long-reach applications in conjunction with optical

amplification. Using electro-absorption technology, the OC48 DWDM cards provide a solution at the

lower extended long-reach distances.

The OC48 ELR 200 GHz interface features a 1550-nm laser and contains a transmit and receive

connector (labeled) on the card faceplate. The card uses SC connectors and supports 1+1 unidirectional

and bidirectional protection switching.

The OC48 ELR 200 GHz cards detect LOS, LOF, LOP, AIS-L, and RDI-L conditions. The cards also

count section and line BIP errors. To enable APS, the OC48 ELR 200 GHz cards extract the K1 and K2

bytes from the SONET overhead. The DCC bytes are forwarded to the TCC2/TCC2P card; the

TCC2/TCC2P terminates the DCC/GCC.

Table 4-14 describes the three card-level LEDs on the OC48 ELR 200 GHz cards.

You can find the status of the OC48 ELR 200 GHz card ports by using the LCD screen on the

ONS 15454 fan-tray assembly. Use the LCD to quickly view the status of any port or card slot; the screen

displays the number and severity of alarms for a given port or slot.

Note For hardware specifications, see the “A.6.13 OC192 SR/STM64 IO 1310 Card Specifications” section

on page A-36. See Table 4-2 on page 4-4 for optical card compatibility.

The OC192 SR/STM64 IO 1310 card provides one intra-office haul SONET/SDH OC-192 port in the

1310-nm wavelength range, compliant with ITU-T G.707, ITU-T G.691, ITU-T G.957, and Telcordia

GR-253-CORE. The port operates at 9.95328 Gbps over unamplified distances up to 2 km (1.24 miles).

The card supports VT, nonconcatenated (STS-1), or concatenated payloads.

Table 4-14 OC48 ELR 200 GHz Card-Level Indicators

Card-Level Indicators Description

Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready. Replace

the card if the red FAIL LED persists.

Green/Amber ACT

LED

The green ACT LED indicates that the card is carrying traffic or is

traffic-ready. The amber ACT LED indicates that the card is part of an active

ring switch (BLSR).

Amber SF LED The amber SF LED indicates a signal failure or condition such as LOS, LOF,

or high BERs on the card’s port. The amber SF LED is also on if the transmit

and receive fibers are incorrectly connected. If the fibers are properly

connected, the light turns off.
