        Ethernet in the First Mile Copper (EFMCu) Interfaces MIB

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This document defines Management Information Base (MIB) modules for
   use with network management protocols in TCP/IP-based internets.
   This document describes extensions to the Ethernet-like Interfaces
   MIB and Medium Attachment Unit (MAU) MIB modules with a set of
   objects for managing Ethernet in the First Mile Copper (EFMCu)
   interfaces 10PASS-TS and 2BASE-TL, defined in IEEE Std 802.3ah-2004
   (note: IEEE Std 802.3ah-2004 has been integrated into IEEE Std 802.3-
   2005).  In addition, a set of objects is defined, describing cross-
   connect capability of a managed device with multi-layer (stacked)
   interfaces, extending the stack management objects in the Interfaces
   Group MIB and the Inverted Stack Table MIB modules.

RFC 5066                  EFMCu Interfaces MIB             November 2007

1.  Introduction

   New Ethernet-like interfaces have been defined in the Institute of
   Electrical and Electronics Engineers (IEEE) Standard 802.3ah-2004
   [802.3ah], a.k.a.  Ethernet in the First Mile (EFM), which is now a
   part of the base IEEE Standard 802.3-2005 [802.3].  In particular,
   2BASE-TL and 10PASS-TS physical interfaces (PHYs), defined over
   voice-grade copper pairs, have been specified for the long and short
   reach, respectively.  These interfaces, collectively called EFM
   Copper (EFMCu), are based on Single-pair High-speed Digital
   Subscriber Line (SHDSL) [G.991.2] and Very High speed Digital
   Subscriber Line (VDSL) [G.993.1] technology, supporting optional
   Physical Medium Entity (PME) aggregation (a.k.a. multi-pair bonding)
   with variable rates.

   2BASE-TL PHY is capable of providing at least 2 Mbps over a 2700 m
   long single copper pair with a mean Bit Error Rate (BER) of 10^-7
   (using 5 dB target noise margin).

   10PASS-TS PHY is capable of providing at least 10 Mbps over a 750 m
   long single copper pair with a mean BER of 10^-7 (using 6 dB target
   noise margin).

   This memo defines a Management Information Base (MIB) module for use
   with network management protocols in the Internet community to manage
   EFMCu interfaces.  In addition, a MIB module is defined describing
   the cross-connect capability of a stacked interface.
