An NML "port" is equivalent to a G.800 "Forwarding Point" (or G.805 "Connection Point").
I usually refer to it as a "logical interface", to clearly distinguish it from a "physical interface".
FYI, NML has no term or concept for a "physical interface" or "physical port" other than to define it as a (logical) port on the Fiber layer. However, that concept would not include the full complexity of a physical port (e.g. adaptations to link connections on higher layers whose data pass through the physical interface, or the exact position in a device where the XFP is plugged in). If it is useful to add this concept of "physical port" next to the current "Port" (which is a logical connection point), I'm happy to hear about a use-case or a proposal. Freek
