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.

The L1 Operator UNI Service Attribute values are agreed to by the SP/SO and the Operator.

An Operator L1VC is an association of two Operator L1VC End Points. Reference MEF 63 Section 8.4 Operator L1VC Service Attributes.

An Operator L1VC End Point represents the logical attachment of an Operator L1VC to an EI. Reference MEF 64 Section 8.5 Operator L1VC End Point Service Attributes.

The UNI is the physical demarcation point between the responsibility of the L1 Service Provider and the responsibility of the L1 Subscriber. Reference MEF 63 Section 8.

A subscriber L1VC represents the logical attachment of a Subscriber L1VC to two SubscriberL1VCEndPoint. Reference MEF 63 Section 8.2.
