Figure 2. MRC-4 Card
The MRC cards, depending upon the selected SFP, can carry concatenated payloads of STS-
3c/VC-4, STS-6c/VC-4-2c, STS-12c/VC-4-4c, STS-24c/VC-4-8c, and STS-48c/VC-4-16c as well as
nonconcatenated payloads on an STS-1, VC-4, VC-3, VC-12, VC-11, and VT1.5 basis. In SONET
applications, the cards are software-provisionable to transport SDH payloads over SONET in the
form of STS-Nc-concatenated payloads. When operated within the outlined specifications, each
card transports signals with a maximum bit error rate of 1 per trillion.
The MRC cards are deployable in any of the 12 service interface card slots of the Cisco ONS
15454 MSPP. Their bandwidth also depends upon the cross-connect card operating within the
system as well as the interface slot where the cards are installed. Their ports can be
commissioned for use in four different architectures – unidirectional-path switched ring/subnetwork
connection protection (UPSR/SNCP), 2-fiber and 4-fiber bidirectional line switched ring/multiplex
section-shared protection ring (BLSR/MS-SPR), 1+1 automatic protection switching/line multiplex
section protection (APS/LMSP), or path-protected mesh network (PPMN) – providing the flexibility
to build the type of networks required to meet service demands, traffic patterns, and user needs.
This card-provisioning flexibility also helps to reduce the cost of inventory and simplifies
engineering and deployment.
The MRC cards provide in-service upgrade capabilities from single-port optics cards utilizing the
same service slot. They also support line-rate span upgrades through the upgrading of an SFP
module.
The cards incorporate faceplate-mounted LEDs to provide a quick visual check of the operational
status at the card as well as the individual ports. The fan-tray-mounted liquid crystal display (LCD)
and soft keys provide the technician local access to the wavelength of each DWDM or CWDM
optical port without the need to access the craft manager. Printed on the faceplate is an orange
circle icon, which indicates the shelf slot where the card can be physically installed.
The card is supported by the integrated Cisco Transport Controller craft manager for the Cisco
ONS 15454 MSPP. The controller provides the user with access to operations, administration,
maintenance, and provisioning for the system. Access to inventory data for the installed MRC card
and pluggable optics modules is available through the craft manager, the Cisco Transport
Manager element management system, and Transaction Layer 1 requests.
