CISCO ONS 15454
The ONS 15454 M12 MSTP features a compact 11-rack-unit chassis offering 17 slots. It accommodates the deployment of multi-degree, multi-wavelength, dense wavelength division multiplexing (DWDM) systems in a convenient quarter-rack system. Commonality with the Cisco ONS 15454 Multiservice Provisioning Platform (MSPP) allows the deployment of hybrid SONET and DWDM configurations. This eases migration from time division multiplexing (TDM) to networks based primarily upon IP services transported over DWDM wavelengths.
