Ethernet over PDH or EoPDH is one of many techniques that provided Ethernet connectivity over non-Ethernet networks. Specifically, EoPDH is a standardized methodology for transporting native Ethernet frames over the existing telecommunications copper infrastructure by leveraging the established PDH transport technology. EoPDH is one of several Ethernet transport technologies that enables Telecommunication Service Providers to offer "Carrier Ethernet" services. Also commonly used as a means of connecting businesses to a Metro Ethernet network.
EoPDH is based on a collection of technologies and standards that allow telecommunications Carriers to make use of their extensive networks of legacy PDH and SONET/SDH (Synchronous Digital Hierarchy) equipment to provide new Ethernet services. In addition, the collection of EoPDH standards provide for interoperability and the gradual migration of Carriers to Ethernet network.
