Ethernet Private Line (EPL) is a Metro Ethernet service type defined by the Metro Ethernet Forum. It describes any E-Line Metro Ethernet service that does not permit service multiplexing at the Ethernet user-to-network interface (UNI).

Because E-Line services implement point-to-point Ethernet virtual connections (EVC), if both UNIs associated with point-to-point EVC implement an EPL service, any further connectivity requirements will require additional UNIs at one or both ends. This service is literally point-to-point.

Because there is only one EVC per UNI, the EVC can be invisible to the customer (e.g., the customer will not see an 802.1p VLAN tag).
