         Managed Objects for Time Division Multiplexing (TDM)
                  over Packet Switched Networks (PSNs)

Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes managed objects for pseudowire
   encapsulation for structured or unstructured Time-Division
   Multiplexing (TDM) (T1, E1, T3, E3) circuits over a Packet Switched
   Network (PSN).

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.

1.  Introduction

   This document describes a model for managing TDM pseudowires, i.e.,
   TDM data encapsulated for transmission over a Packet Switched Network
   (PSN).  The term TDM in this document is limited to the scope of
   Plesiochronous Digital Hierarchy (PDH).  It is currently specified to
   carry any TDM Signals in either Structure Agnostic Transport mode
   (E1, T1, E3, and T3) or in Structure Aware Transport mode (E1, T1,
   and NxDS0) as defined in the Pseudowire Emulation Edge-to-Edge (PWE3)
   TDM Requirements document [RFC4197].

   This document is closely related to [SATOP], [TDMOIP], and [CESOPSN],
   which describe the encapsulation of TDM signals and provide the
   Circuit Emulation Service over a PSN.

   The TDM management model consists of several MIB modules, following
   the layering model described in the PWE3 Architecture document
   [RFC3985].  The TDM MIB module described in this document works
   closely with the MIB modules described in [DS3MIB], [DS1MIB],
   [DS0MIB], [IFMIB], [PWMIB], and with the textual conventions defined
   in [PWTC].  The conceptual layering and relationship among all those
   is described in Figure 1 below.  A TDM connection will be a
   pseudowire (PW) connection.  It will not be treated as an interface
   and will therefore not be represented in the ifTable.
