Broadband Access Networks are being used to provide Internet Access and multimedia services to Subscribers. Service Providers have begun purchasing Carrier Ethernet and Carrier Ethernet-like Services over these networks and are using them to provide OSI Layer 2 access to their Subscribers’ locations.
In this document Broadband Access Networks include DOCSIS®, Passive Optical Networks (PON), and satellite networks.
Due to the technologies used and the architectural choices made, some of these Broadband Access Networks do not fully comply with the requirements for Operator Ethernet Services specified in MEF 51.1 and MEF 26.2. This document defines two new Operator Ethernet Services, Broadband Access E-Line and Broadband Access E-LAN, to address these use cases. These new Services are modeled on the Access E-Line and Access E-LAN Services defined in MEF 51.1 which are based on the Service Attributes defined in MEF 26.2. To accommodate the use of Broadband Networks for delivering Ethernet Services, this document allows additional Service Attribute values beyond those in MEF 51.1 and MEF 26.2. This document also explains the rationale for each deviation from MEF 51.1 and MEF 26.2.
