You can install OC192 SR/STM64 IO 1310 cards in Slot 5, 6, 12, or 13. You can provision this card as
part of a BLSR, a path protection, a linear configuration, or as a regenerator for longer span reaches.
The OC192 SR/STM64 IO 1310 port features a 1310-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 BLSR applications where both span switching and ring switching might
occur.
The OC192 SR/STM64 IO 1310 card detects SF, LOS, or LOF conditions on the optical facility. Refer
to the Cisco ONS 15454 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.
