OC-192/STM-64 Transport for Carrier’s Carrier Services
In each of these network applications, the user can provide a mixture of service types over the same Cisco ONS 15454 platform, taking
advantage of the other supported interface types, including DS-n/E-n private line, D1/SDI and C-Cor DV6000 video, Ethernet, ESCON, and
SONET/SDH OC-n/STM-m.
THE CISCO ADVANTAGE
The Cisco ONS 15454 2.5G Transponder Card complements and extends the services capabilities of the Cisco ONS 15454 platform. The 2.5G
transponder card enables users to deliver wavelength services over their existing fiber plant over a proven Cisco ONS 15454 platform that also
supports service aggregation, including DS-1/E-1, DS-3/E-3, OC-n/STM-n, and Ethernet. The Cisco ONS 15454 platform enables users to
reduce the need to deploy standalone metro DWDM and multiservice provisioning platforms (MSPPs) to transport a mixture of services, as
outlined in Figures 8 and 9.
