With the introduction of a new two-port Gigabit Ethernet card, model G1000-2, for the Cisco ONS 15327 Optical Transport Platform, service providers can now deliver gigabit media flexibility without building an overlay network or redesigning their existing SONET infrastructure. The unprecedented time-division multiplexing (TDM) capabilities of the Cisco ONS 15327, combined with evolutionary Gigabit Ethernet capabilities, enable service providers to deliver on the key market differentiators needed to ensure their success.
