The Cisco® ONS 15454 60G/5G High-Order/Low-Order XC-VXC Cross-Connect Card expands the low-order bandwidth management capabilities of the Cisco ONS 15454 SONET and SDH multiservice provisioning platforms (MSPPs)
The Cisco ONS 15454 60G/5G High-Order/Low-Order XC-VXC Cross-Connect Card (XC-VXC) increases the Cisco ONS 15454's virtual tributary (VT)1.5 and VC-12 switching matrixes by a factor of four, facilitating greater support for grooming DS-1 and E1 services and low-order members of virtual concatenation (VCAT) groups. The XC-VXC card operates in a protected 1:1 configuration, helping enable carrier-class high availability and supporting errorless side switching. The card operates in either the Cisco ONS 15454 SONET or SDH systems. In SONET systems, the card supports cross-connections at the VT-1.5, VT-2, STS-1, and STS-Xc (where X = 3, 6, 9, 12, 24, 48, and 192) granularities and in SDH systems (AU-4) at VC-12, VC-11, VC-3, VC-4, and VC-4-Xc (where X = 2, 3, 4, 8, 16, and 64) granularities.
The card provides 60 Gbps of nonblocking, high-order switch capacity, 1152 x 1152 STS-1s or 384 x 384 VC-4s unidirectional ports and 5 Gbps of low-order switch capacity, 2688 x 2688 VT1.5/VC-11, or 2016 x 2016 VT-2/VC-12 unidirectional ports. The XC-VXC card is installed in slots 8 and 10 as identified by the green cross (+) icon at the bottom of the faceplate and below the shelf slot. The platform's eight multiservice card slots (1 to 4 and 14 to 17) receive 2.5 Gbps of capacity and the high-speed card slots (5, 6, 12, 13) receive 10 Gbps of capacity. The timing, communications, and control (TCC) card works with the XC-VXC card to provision, set up circuits, and maintain connections within the system. The XC-VXC card provides in-service upgrade capabilities, given shelf assembly support, from other cross-connect cards, including the XC, XC-VT, XC-10G, XC-VXL-2.5G, and XC-VXL-10G.
The XC-VXC card can be commissioned to support multiple network and circuit-protection schemes including unidirectional path switched ring/subnetwork connection protection (UPSR/SNCP) per Telcordia Technologies GR-1400-CORE/ITU G.841; 2-fiber and 4-fiber bidirectional line switched ring/multiplex section-shared protection ring (BLSR/MS-SPR) per GR-1230/ITU G.841; 1+1 automatic protection switching/line multiplex section protection (APS/LMSP) per GR-253-CORE/ITU G.841; path-protected mesh network (PPMN) GR-1400-CORE; or unprotected architectures, providing the flexibility to build the type of networks required to meet service demands, traffic patterns, and user needs. This provisioning flexibility also helps to reduce the cost of inventory and simplifies engineering and deployment.
The XC-VXC card incorporates faceplate-mounted LEDs to provide a quick visual check of the operational status at the card. 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 (OAM&P) for the system.
