a platform that can transport both traditional time-division multiplexing (TDM) traffic, such as voice, yet also provide the foundations for data traffic, which Ethernet is optimized for

a platform that can transport traditional circuit-based TDM traffic such as voice, but also supports native data services (such as switched Ethernet) that offer efficient and cost-effective services over SONET/SDH infrastructure

a TDM-based network element that has evolved to support additional interfaces, including dense wavelength-division multiplexing (DWDM), Ethernet, and storage area networking (SAN)
