General Description
EoPoS is a standardized method for transporting native Ethernet frames over a SONET/SDH network, by first mapping into one or more PDH tributaries such as T1, E1, or DS3. The tributaries can then be dropped from a legacy ADM, delivered to the customer premise, and the PDH links resolved back to an Ethernet connection by a piece of equipment supporting EoPDH.
The technologies used in EoPoS include GFP frame encapsulation, Ethernet Mapping, Virtual Concatenation, Link Capacity Adjustment Scheme, and Management Messaging (OAM). Common practices in EoPoS equipment also include the tagging of traffic for separation into virtual networks, prioritization of user traffic.
