• Network topology – The platform supports ring, linear, and mesh topologies or a combination of these topologies from a single network

element. To simplify engineering, ordering, and sparing, the optical transport interface cards are not topology type specific, as is the case

with many transport platforms, allowing a single card type to be software provisioned to support any of the network topologies.

• Intelligent WDM – The Cisco ONS 15454 provides best-in-class metro DWDM using its multiservice-transport-platform (MSTP) qualities,

providing integrated, intelligent WDM capabilities, including automatic power sensing and control, optical filters including industry-leading

reconfigurable optical add/drop multiplexer (ROADM), optical amplifiers, optical service channel, narrowband optical interfaces, and IP-

enabled network operations. Taking advantage of the MSTP configuration, the platform allows simple, fast, and easy network bandwidth

scalability from 2.5 to 320 Gbps and beyond as well as a comprehensive selection of wavelength services. The platform is easily configured

to support multiple DWDM node types, including hub, terminal, amplifier, and add/drop. The MSTP solution simplifies DWDM

deployments by providing automated network level power control, ROADMs, downloadable node turn-up settings and fiber cabling

diagrams generated by the Cisco MetroPlanner DWDM network design tool, and A-to-Z wavelength provisioning. More information

These flexible optical networking capabilities allow deployment of a single platform type in a wider range of customer applications, simplifying

training, equipment sparing, and OSS and NMS integration.

Integrated Multiservice Aggregation

Metro and regional networks, versus the long-haul networks, reach closer to the end-user equipment, and thus require a broad mix of service

interfaces and high-density service aggregation to accommodate all the data, voice, storage, and video data services. The Cisco ONS 15454

supports a comprehensive selection of service interface types, including synchronous, asynchronous, electrical, optical, data, and storage.

Efficient bandwidth use is supported through the central cross-connect fabric, supporting time-division multiplexing in multiple bandwidth

increments including VT1.5, VC-11, VT2, VC-12, STS-N/VC-3, and VC-4 levels.

The Cisco ONS 15454 builds on the integration of Layer 2 and Layer 3 packet processing in an optical transport platform. Taking advantage of

Cisco Systems

data expertise, the Cisco ONS 15454 also provides advanced quality of service (QoS) as well as Resilient Packet Ring (RPR)

technology that helps enable more efficient use of the network transport resources to lower CapEx requirements and improve the network return

on investment (ROI).

The growing demands for remote database backup is necessitating the transport of storage interfaces, such as 1- and 2-Gbps Fibre Channel/Fiber

Connection (FICON) and Enterprise Systems Connection (ESCON). The Cisco ONS 15454 provides the option to transport storage traffic over

a SONET/SDH or DWDM network. The platform takes advantage of a distance-extension protocol to extend the reach of the storage network as

well as its service bandwidth subrating to allow the transport bandwidth to better match the service requirements.

Service flexibility is further strengthened by the transponder solution, which is part of the system’s MSTP function that can transparently

transport a wide range of service types with advanced networking capabilities using G.709 digital wrapper and forward error correction.
