An OVC End Point is a logical entity at a given External Interface that is associated with a distinct set of frames passing over the External Interface. Reference MEF 26.2 Section 16 OVC End Point Service Attributes.

The Subscriber UNI Service Attributes values are agreed to by the Subscriber and the Service Provider to describe the behavior of the UNI.

This class represents the Virtual UNI Service Attributes that are agreed on by the SP/SO and the Operator for each UNI. Reference MEF 26.2 Section 15 Virtual UNI (VUNI), Feeder OVC, and Remote UNI (RUNI).

An External Network Network Interface (ENNI) is the demarcation point between the responsibility of one Operator and another in other words, it is the interface where the two Operators interconnect. Reference MEF 61.1 Section 8.2 ENNI and ENNI Links.

An ENNI can comprise one or more distinct IP Links, each of which is a single IP hop. These links are known as ENNI Links, and typically each corresponds to a distinct IP subnet (which can have both IPv4 and IPv6 addressing). ENNI Links are assumed to be point-to-point. Reference MEF 61.1 Section 8.2 ENNIs and ENNI Links.

A User Network Interface (UNI) is the demarcation point between the responsibility of the SP and the responsibility of the Subscriber. Note that a given UNI always relates to a single SP and a single Subscriber. Reference MEF 61.1 Section 7.3 UNIs and UNI Access Links.

An individual connection between the Subscriber and the SP that forms part of a UNI. Reference MEF 61.1 Section 7.3 UNIs and UNI Access Link.

A UNI Access Link Trunk is a construct that encapsulates the details of Layer 1 and Layer 2 configuration shared by one or more UNI Access Links. Reference MEF 61.1.1 Section A1-1 UNI Access Link Trunk Service Attributes.

An IP Service is formed of an IP Virtual Connection (IPVC) that links together IPVC End Points at External Interfaces (EIs). Reference MEF 61.1 Section 7.4 IP Virtual Connections and IPVC End Points.

An IPVC End Point is a logical entity at an EI, to which a subset of packets that traverse the EI is mapped. Reference MEF 61.1 Section 7.4 IP Virtual Connections and IPVC End Points.

The L1 ENNI class controls Operator Network behaviors that enable Operator Networks to be interconnected and exchanged OTUk frames. The interconnection is achieved by the Operators agreeing on the value for each ENNI attributes. Reference MEF 64 Section 8.1 ENNI Common Attributes.

For each instance of an ENNI, there are multiple sets of ENNI Service Attributes. The value for each ENNI Service Attribute in a set for an Operator network is specific to the SP/SO that is using the ENNI. Reference MEF 64 Section 8.2 ENNI Service Attributes.
