4.5 OC12 LR/STM4 LH 1310 Card
Note For hardware specifications, see the “A.6.4 OC12 LR/STM4 LH 1310 Card Specifications” section on
page A-28. See Table 4-2 on page 4-4 for optical card compatibility.
The OC12 LR/STM4 LH 1310 card provides one long-range SONET OC-12 port per card compliant
with ITU-T G.707, ITU-T G.957, and Telcordia GR-253-CORE. The port operates at 622.08 Mbps over
a single-mode fiber span. The card supports VT, nonconcatenated (STS-1), or concatenated (STS-3c,
STS-6c, or STS-12c) payloads. Figure 4-4 shows the OC12 LR/STM4 LH 1310 faceplate and a block
diagram of the card.
Note The OC12 LR 1310 and OC12 LR/STM4 LH 1310 cards are functionally the same.
Warning
The laser is on when the optical card is booted. The port does not have to be in service for the laser
to be on.

Card-Level Indicators Description
Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready. This LED
is on during reset. The FAIL LED flashes during the boot process. Replace
the card if the red FAIL LED persists.
Green/Amber ACT
LED
The green ACT LED indicates that the card is operational and 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,
AIS-L, or high BERs on one or more of the card’s ports. The amber SF LED
is also on if the transmit and receive fibers are incorrectly connected. If the
fibers are properly connected and the link is working, the light turns off.
