Evolution
from SONET/SDH to Multiservice Provisioning Platforms
Traditional SONET is optimized for TDM voice traffic, but can't scale for exponential bandwidth demands, nor can it provide the multiservice flexibility today's networks need. Multiservice provisioning platforms have emerged to address the constraints that legacy SONET/SDH equipment fails to overcome in the complex, evolving metro environment, without sacrificing the many benefits of SONET/SDH. Based on next-generation SONET and dense wavelength division multiplexing (DWDM) technologies, multiservice provisioning platforms enable service providers to deliver high-value voice, data, and wavelength services, over any optical bit rate (OC-3, OC-12, OC-48, OC-192, and DWDM). As the leader in this product category, Cisco combines comprehensive service capabilities into compact platforms, integrating both optical and electrical networking. These evolutionary platforms provide efficient and robust multiservice capabilities (DS1, DS3, EC1, OCn, video, Ethernet - 10/100 and Gigabit) for greater profitability. Additionally, by enabling service providers to incrementally, rapidly, and cost-effectively add new services and create revenue opportunities, multiservice platforms also help drive profitability in the metro area network (MAN), where topologies, services, and technologies are vastly different. Metro service providers are increasingly selecting next-generation multiservice provisioning platforms (MSPPs) to address their metro needs. Cisco Multiservice Provisioning Platforms
