The objects in this MIB module are used to manage the Ethernet in the First Mile (EFM) Copper (EFMCu) Interfaces 2BASE-TL and 10PASS-TS, defined in IEEE Draft P802.3ah/D3.3. The following reference is used throughout this MIB module: [802.3ah] refers to: IEEE Std 802.3ah-2004: 'IEEE Standard for Information technology - Telecommunications and information exchange between systems - Local and metropolitan area networks - Specific requirements - Part 3: Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Access Method and Physical Layer Specifications - Amendment: Media Access Control Parameters, Physical Layers and Management Parameters for Subscriber Access Networks', 07 September 2004. Of particular interest are Clause 61, 'Physical Coding Sublayer (PCS) and common specifications, type 10PASS-TS and type 2BASE-TL', Clause 30, 'Management', Clause 45, 'Management Data Input/Output (MDIO) Interface', Annex 62A, 'PMD profiles for 10PASS-TS' and Annex 63A, 'PMD profiles for 2BASE-TL'.
