ADTRAN’s Ethernet over Copper (EoCu) products enable service providers to extend packet-based business-class services beyond the reach of their fiber networks by leveraging the existing investment of copper-based TDM business services assets. This means leveraging the full advantages of TDM, the most understood, successful, and ubiquitous business service infrastructure. Due to budget restrictions and time to market requirements, deploying fiber to address nascent or disperse service demand is not feasible. This leaves a large percentage of businesses to rely on copper business access.
