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 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.
The SNMPv2 Network Management Framework consists of four major components. They are:
The Framework permits new objects to be defined for the purpose of experimentation and evaluation.
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.

agent shall make this determination in an implementation- specific manner that may take into account the configuration of other capabilities or other considerations. The modem will choose in an implementation-specific manner between multiple mutually-exclusive capabilities that each have the same (non-disabled) value. However, the modem must prefer all capabilities with a value of 'preferred(3)' over all capabilities with a value of 'optional(2)'.
In other words, if there are one or more mutually-exclusive
capabilities (e.g. V.32 and V.32bis) that are set to
`preferred', the agent must choose one in an
implementation-specific manner. Otherwise, if there are one
or more mutually-exclusive capabilities that are set to
`optional', the agent must choose one in an implementation-
specific manner."

"Indicates the reason that the last connection or attempt failed. The meaning of each reason code is explained below.
unknown:
This code means the failure reason is unknown or
there has been no previous call.
other:
This code used when no other code is applicable.
Additional vendor information may be available
elsewhere.
managementCommand:
A management command terminated the call. These commands include escaping to command mode, initiating dialing, restoring lines, and disconnecting.
inactivityTimeout:
The call was terminated because it was inactive for
at the minimum duration specified.
mnpIncompatibility:
The modems are unable to resolve MNP protocol
differences.
protocolError:
An error occured in one of protocol in use. Further
information is required to determine in which
protocol the error occurred, and the exact nature of
the error.
powerLoss:
The modem lost power and disconnected the call.
equipmentFailure:
The modem equipment failed.
dtrDrop:
DTR has been turned off while the modem is to
disconnect on DTR drop. (Ref: V.58 cct108TurnedOff)
noDialTone:
If the modem is to monitor for call progress tones,
but the modem has failed to detect dial tone while
attempting to dial a number.
lineBusy:
Busy signal is detected while busy signal detection
is enabled, or while the 'W' or '@' dial modifier is
used. (Ref: V.58 engagedTone)
noAnswer:
The call was not answered.
voiceDetected:
A voice was detected on the call.
carrierLost:
Indicates that the modem has disconnected due to
detection of loss of carrier. 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.
faxDetected:
A fax was detected on the call."
