1. Status of this Memo
This document is an Internet-Draft. Internet-Drafts are
working documents of the Internet Engineering Task Force
(IETF), its Areas, and its Working Groups. Note that other
groups may also distribute working documents as Internet-
Drafts.
Internet-Drafts are draft documents valid for a maximum of six
months and may be updated, replaced, or obsoleted by other
documents at any time. It is inappropriate to use Internet-
Drafts as reference material or to cite them other than as a
"work in progress".

draft ATM Textual Conventions and OBJECT-IDENTITIES 4/6/96
2. Introduction
This memo describes Textual Conventions and OBJECT-IDENTITIES
used for managing ATM-based interfaces, devices, networks and
services.
When designing a MIB module, it is often useful to define new
types similar to those defined in the SMI. In comparison to a
type defined in the SMI, each of these new types has a
different name, a similar syntax, but a more precise
semantics. These newly defined types are termed textual
conventions, and are used for the convenience of humans
reading the MIB module. This is done through Textual
Conventions as defined in RFC1903[1]. It is the purpose of
this document to define the set of textual conventions
available to ATM MIB modules.
When designing MIB modules, it is also often useful to
register further properties with object identifier assignments
so that they can be further used by other MIB modules. This
is done through the OBJECT-IDENTITY macro defined in
RFC1902[2]. This document defines OBJECT-IDENTITIES available
to ATM MIB modules.
This memo does not specify a standard for the Internet
community.
