Cisco continues to expand service densities on the ONS 15454 MSPP with the introduction of the high-density OC-12/STM-4 card. The four-port OC-12/STM-4 card offers four times the density of the current OC-12/STM-4 card and enables service providers to expand the number of revenue-generating service interfaces from an existing or new ONS 15454. Enterprise users and service providers can also take advantage of lower overall network infrastructure costs by reducing the number of chassis and interface cards for future network build-outs.
