Ethernet over SONET/SDH

Service demand in metro networks is growing, but providers must be conservative and cost-conscious as they expand or evolve networks to meet new demand. They need to extend the value of installed systems, run more services on existing networks, retain customers by offering on-demand access to a choice of service types, and reduce the cost of providing those services.

SONET and SDH (the international standard) have been widely deployed by telephone companies and common carriers for more than a decade. This reliable, Layer 1 transport technology based on time-division multiplexing (TDM) continues to reap revenues from traditional voice and leased-line data traffic.

However, the growing popularity of Ethernet raises some new issues for SONET/SDH networks. As customers seek to extend Ethernet services across multiple locations in a city or region, SONET/SDH networks have to adapt to respond. The winning solution for today’s  market is a platform that extends the value of your investment in SONET/SDH while delivering all of your metro services economically, flexibly and reliably.

That winning solution is the Overture Networks ISG converged packet access platform— an  edge solution that bridges the TDM and packet worlds to deliver flexible, high-speed Ethernet services over existing SONET/SDH backbones.
