Subject: FYI: What new MIB would look like
If there are no strong objections to the items I identified that we've
reached concensus on, and we are to reach concensus on my proposals,
this is what the resulting MIB would look like. The change bars are
with respect to the last Internet-Draft.

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 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".

1. Introduction
This memo defines an experimental portion of the Management Information
Base (MIB) for use with network management protocols in the Internet
community. In particular, it describes managed objects used for
managing dial-up modems and similar dial-up devices. This MIB module
provides a set of objects that are the minimum necessary to provide the
ability to monitor and control those devices, and is consistent with the
SNMP framework and existing SNMP standards.
Expires July 14, 1994 [Page 2]
draft Modem MIB January 14, 1994
2. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
o RFC 1442 which defines the SMI, the mechanisms used for describing
and naming objects for the purpose of management.
o RFC 1213 defines MIB-II, the core set of managed objects for the
Internet suite of protocols.
o RFC 1445 which defines the administrative and other architectural
aspects of the framework.
o RFC 1448 which defines the protocol used for network access to
managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2.1. Object Definitions
Managed objects are accessed via a virtual information store, termed the
Management Information Base or MIB. Objects in the MIB are defined
using the subset of Abstract Syntax Notation One (ASN.1) defined in the
SMI. In particular, each object object type is named by an OBJECT
IDENTIFIER, an administratively assigned name. The object type together
with an object instance serves to uniquely identify a specific
instantiation of the object. For human convenience, we often use a
textual string, termed the descriptor, to refer to the object type.

DESCRIPTION
"Indicates the reason that the last connection or connection
attempt failed. The following explains the meaning of each
reason code.
other:
This code is selected when no other code is applicable.
unknown:
This code is selected when the failure reason is unknown.
managementCommand:
The network management system has issued a command to the
modem, for example, to initiate a dial call, a redial, or
a dial disconnect.
inactivityTimerExpired:
See the description under the 'mdmDTEInactivityTimeout'
object.
dtrDrop:
DTR has been turned off while the modem is strapped to
disconnect on DTR drop, for example, as specified
in TIA-602 (AT&D2).
callSetupFailTimerExpired:
The call establishment timer, for example, as specified
in TIA-602 (S7 register) has expired.
noAnswer: XXX
noCarrier: XXX
loopCurrentInterrupted:
For a GSTN connection, usually indicates that the line
interface cable has been disconnected from the modem or
the wall socket.
noDialTone:
If the modem is strapped to monitor for call progress tones,
for example, as specified in TIA-602 (ATX4), the modem has
failed to detect dial tone while attempting to dial a number.
voiceDetected: XXX
lineBusy:
Busy signal is detected while busy signal detection is enabled,
for example, as specified in TIA-602 (ATX4), or while
Expires July 14, 1994 [Page 20]
draft Modem MIB January 14, 1994
the 'W' or '@' dial modifier is used.
noAnswerTone: XXX
carrierLost:
Indicates that the modem has disconnected due to detection of
loss of carrier, providing the modem has been strapped
accordingly. In TIA-602, the S10 register determines the time
that loss of carrier must be detected before the modem
disconnects.
trainingFailed:
Indicates that the modems did not successfully train and reach
data mode on the previous connection.
noModulationInCommon:
Indicates that, during call establishment, the modems
determined that they had no common modulation.
invalidSpeed: XXX
retrainFailed:
Indicates that, although the modems did reach data mode on
the previous connection, they failed to reach data mode during
a subsequent retrain attempt.
gstnCleardownReceived:
Indicates that a GSTN cleardown code was received from the
remote modem (for example, a V.32 rate code with the rate bits
all cleared).
faxDetected: XXX
anyKeyAbort:
Indicates that the previous call was aborted before data mode
was reached, because the modem (either calling or answering)
received an extra character from the DTE.
dteHangupCommand:
Indicates that, while in command state, the modem received
a hangup command, for example, as specified in TIA-602 (ATH).
escapeSequence: XXX
dteResetCommand: XXX
linkDisconnectMsgReceived:
retransmitLimit:
Indicates that, while in V.42 error correcting mode, the
allowable number of retransmission attempts for any particular
frame was exceeded.
negotiationFailed:
Indicates that, while configured for error correcting only
mode,the modems failed to successfully negotiate an error
correcting link.
