The Ethernet Services Plus (ES+) line cards use an extensible design that allows service prioritization for voice, video, and data services. Service providers and enterprises can benefit from the improved economics, density, advanced quality-of-service (QoS) features, and high performance of these fixed-configuration line cards. With the same basic architecture and features, Ethernet Services Plus Extended Transport (ES+XT) line cards support G.709 framing and Forward Error Correction (FEC) across dense wavelength-division multiplexing (DWDM) networks, enabling optical links to span greater distances.
The ES Plus cards' programmable interface processors protect network investments and reduce total cost of ownership. The design increases connectivity options and offers superior service intelligence through programmable interface processors operating at line rate.
