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.
