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 multiplex section-shared protection ring (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.
Each port is configurable to support all ONS 15454 SDH configurations and can be provisioned as part
of an MS-SPRing or SNCP configuration.
To enable an MSP-SPRing, the OC12 IR/STM4 SH 1310-4 card extracts the K1 and K2 bytes from the
SDH overhead and processes them to switch accordingly. The GCC bytes are forwarded to the TCC2
card, which terminates the GCC.
