The objects in this MIB module are used to manage the
Ethernet in the First Mile (EFM) Ethernet Passive Optical
Network (EPON) Interfaces as defined in IEEE P802.3ah
clauses 60, 64, and 65.
The following reference is used throughout this MIB module:
[802.3ah] refers to:
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 - Media Access Control Parameters,
Physical Layers and Management Parameters for subscriber
access networks.  IEEE Std 802.3ah-2004, October 2004.

Of particular interest are clause 64 (Multi-Point Control
Protocol - MPCP), clause 65 (Point-to-Multipoint
Reconciliation Sublayer - P2MP RS), clause 60 (Ethernet
Passive Optical Network Physical Medium Dependent - EPON
PMDs), clause 30, 'Management', and clause 45, 'Management
Data Input/Output (MDIO) Interface'.
