Features and Benefits

• Flexible protection options: The PSM is an addition to the extensive array of protection mechanisms on the Cisco ONS 15454 MSTP, which gives customers the flexibility to choose the appropriate level of protection based on cost and their requirements for network resiliency.
• Cost effectiveness: PSM-based protection is one of the most cost-effective means to provide service resiliency in an optical network. The PMS gives customers an affordable entry-level solution.
• Fast switchover performance: The PSM completes the service switchover in less than 50 milliseconds, which helps ensure minimal disruption to data traffic.
• Easy provisioning and management: The PSM fully integrates with the Cisco ONS 15454 MSTP through Cisco Transport Controller.
• Support for amplified networks: The PSM also works with the Cisco ONS 15454 MSTP amplifiers to extend the reach of the network.

The Cisco Timing, Communications, and Control Version Two Plus card provides a next-generation system processor for the Cisco ONS 15454 MSPP. The Cisco TCC2 card performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection and resolution, SONET data communications channel (DCC) termination, system DC input-voltage monitoring, and system fault detection. This card resides in slots 7 and 11 of the shelf assembly, providing 1:1 equipment protection.

The Cisco TCC2 and TCC2P cards incorporate a highly stable Stratum 3 internal timing reference to provide system timing based on input received from an external Building Integrated Timing Supply source or from an incoming SONET or SDH optical signal. Synchronous status messaging helps the system to select the best timing sources, and a holdover mode maintains timing accuracy in the event that preprovisioned synchronization references are not available.

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 Cisco® CRS-3 Carrier Routing System offers industry-leading performance, advanced services intelligence, environmentally conscious design, and system longevity. The Cisco CRS-3 is powered by the Cisco QuantumFlow Array - a chipset architecture based on multidimensional engineering and Cisco IOS® XR Software, a unique self-healing, distributed operating system.

Packet-based data communications are being replaced by video and rich media traversing the IP Next-Generation Network (NGN) in multiple directions, straining the architectural foundations of both public and private networks serving businesses and consumers. As part of the medianet, a media-aware Cisco IP NGN, the Cisco CRS-3 delivers continuous, always-on operations and scales easily from numerous single-chassis form factors to a massive multi-chassis system. Its design provides an industry-leading efficiency consuming lowest power, cooling and rack-space resources for an intelligent service-rich bandwidth capacity. The CRS-3 builds on the CRS-1 being backward and forward compatible, protecting existing and future investments for decades to come.
