Chapter 4 Optical Cards
4.12.1 OC192 IR/STM64 SH 1550 Card Functionality
Figure 4-20 shows a block diagram of the card.

4.12.1 OC192 IR/STM64 SH 1550 Card Functionality
You can install OC192 IR/STM64 SH 1550 cards in Slot 5, 6, 12, or 13. You can provision this card as
part of an MS-SPRing, SNCP, or linear configuration, or as a regenerator for longer span reaches.
The OC192 IR/STM64 SH 1550 port features a 1550-nm laser and contains a transmit and receive
connector (labeled) on the card faceplate. The card uses a dual SC connector for optical cable
termination. The card supports 1+1 unidirectional and bidirectional facility protection. It also supports
1:1 protection in four-fiber bidirectional line switched ring applications where both span switching and
ring switching might occur.
The OC192 IR/STM64 SH 1550 card detects SF, LOS, or LOF conditions on the optical facility. Refer
to the Cisco ONS 15454 SDH Troubleshooting Guide for a description of these conditions. The card also
counts section and line BIP errors from B1 and B2 byte registers in the section and line overhead.
