              ISDN Management Information Base using SMIv2

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 memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it defines a minimal set of managed objects for SNMP-
   based management of ISDN terminal interfaces.  ISDN interfaces are
   supported on a variety of equipment (for data and voice) including
   terminal adapters, bridges, hosts, and routers.

   This document specifies a MIB module in a manner that is compliant to
   the SNMPv2 SMI.  The set of objects is consistent with the SNMP
   framework and existing SNMP standards.

   This document is a product of the ISDN MIB working group within the
   Internet Engineering Task Force.  Comments are solicited and should
   be addressed to the working group's mailing list at isdn-
   mib@cisco.com and/or the author.

   The current version of this document reflects changes made during the
   last call period and the IESG review.

1.  The SNMPv2 Network Management Framework

   The SNMPv2 Network Management Framework presently consists of three
   major components.  They are:

   o    the SMI, described in RFC 1902 [1] - the mechanisms used for
        describing and naming objects for the purpose of management.

   o    the MIB-II, STD 17, RFC 1213 [2] - the core set of managed
        objects for the Internet suite of protocols.

   o    the protocol, STD 15, RFC 1157 [3] and/or RFC 1905 [4], -
        the protocol for accessing managed objects.
