4.7.1 OC12 IR/STM4 SH 1310-4 Card Functionality
You can install the OC12 IR/STM4 SH 1310-4 card in Slots 1 to 4 and 14 to 17. The card can be
provisioned as part of an SNCP, part of an MS-SPRing, or in an ADM/TM configuration. Each interface
features a 1310-nm laser and contains a transmit and receive connector (labeled) on the card faceplate.
The card uses SC connectors.
The OC12 IR/STM4 SH 1310-4 card supports 1+1 unidirectional and bidirectional protection switching.
You can provision protection on a per port basis.
The OC12 IR/STM4 SH 1310-4 card detects LOS, LOF, LOP, MS-AIS, and MS-FERF conditions. Refer
to the Cisco ONS 15454 SDH Troubleshooting Guide for a description of these conditions. The card also
counts section and line BIP errors.
