What Is NETI-DTM-MIB?
NETI-DTM-MIB manages Dynamic synchronous Transfer Mode (DTM) network configuration on Net Insight equipment, a circuit-switched, time-division based networking technology used for deterministic, low-latency media and data transport. It exposes address and host-mapping configuration data, DTM network addresses (with alias flags and address types) and a hosts table binding DTM addresses to human-readable node names, supporting circuit provisioning across a DTM network element. Though centered on addressing/topology configuration rather than raw performance counters, it is used to confirm the software-level identity and reachability configuration of a DTM node, a prerequisite check before circuit-level performance troubleshooting; row status objects also let administrators confirm the operational validity of each configured address entry. It is a vendor-specific extension built around DTM technology rather than a public IETF standard, so it has no dependency on generic IETF interface MIBs beyond conventional SNMP row-status conventions. It is deployed on Net Insight Nimbra DTM nodes used in professional broadcast and telecom backbone networks requiring guaranteed-bandwidth circuit transport. Engineers can download the NETI-DTM-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in NETI-DTM-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Net Insight Nimbra DTM network element
Monitoring Examples
An operator would walk dtmAddrTable/dtmAddrEntry by dtmAddrEntryIndex to confirm a node's dtmAddrEntryAddr is correctly provisioned and dtmAddrEntryRowStatus shows active rather than notReady, which would indicate an incomplete address configuration blocking circuit setup. Cross-referencing dtmHostsTable/dtmHostsEntry lets the operator confirm that a dtmHostsEntryAddr resolves to the expected dtmHostsEntryName, catching naming/address mismatches that could misroute a DTM circuit. The dtmAddrEntryIsAlias flag distinguishes primary from alias addresses, useful when diagnosing why traffic destined for an alias address isn't reaching the expected DTM interface.
What Can Be Monitored
- DTM address configuration per node
- address alias status
- address row/administrative status
- DTM host name-to-address mapping

The link class decides which values the dtmLinkStateNodeStatus object can take. A link is monitored with the following mechanisms: - The underlying trunk interface will detect when the signal on the receiving interface disappears or is impossible to use due to errors. This is called a Signal Failure. - The communication with the node at the remote end of the link is monitored by periodically sending messages, and expecting responses. If no response is received within a reasonable time, a failure is assumed. This is called a Supervision Failure. The error detection mechanisms can detect failures in one or both directions of a bi-directional link. If a failure is detected in only one direction of a bi-directional link and there is another fully working link in the opposite direction, the remaining working links will all have status `up'. The link classes are: normal(1) If either a Signal Failure or Supervision Failure is detected on the link, the link is considered as `down' and its entry is removed from the dtmLinkStateTable. persistent(2) If a Signal Failure is detected on the link, the link is considered as `down' and its entry is removed from the dtmLinkStateTable. If a Supervision Failure is detected on the link, the object dtmLinkStateIfNodeStatus for the link is assigned `noControl'. nailed(3) If a Signal Failure is detected on the link, the object dtmLinkStateIfNodeStatus for the link is assigned `downKeep'. If a Supervision Failure is detected on the link, the object dtmLinkStateIfNodeStatus for the link is assigned `noControl'. |

The time scale is however running, so it may be used for relative measures such as those used in round-trip estimates. During the uninitiated state the Time Transfer Control Processing attempts to initiate the TAI/UTC time from either another DTM node in state compensated, or some local UTC source. When the such a source is available, it reassigns the time scale and enters the reassigned state. reassigned(3) When the time scale of this node have a degenerated time-offset from neighbor nodes being compensated, or a local TAI/UTC source, the node reassigns the time scale and enters the reassigned state, during which the time scale may not be used for precision time-keeping. During the reassigned state the Time Transfer Control Processing attempts to retrace the TAI/UTC time from either another DTM node in state compensated, or some local TAI/UTC source. When the retracing have reduced the time error to within defined limits (1 us), it enters the compensated state. compensated(4) When the time scale of the node has been initiated to TAI/UTC, it can be used for time keeping, but the time error of the time scale is too high (and thus stability and precision is limited). During the compensated state the Time Transfer Control Processing will use the TLL to maintain the TAI/UTC time scale from any neighboring nodes in the compensated state. |
| INT dtmTimeSourceAdminStatus | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1.3 | INTEGER | read-write | The desired state of the interface. The administrative status controls whether the time source should be active or not. |
| I32 dtmTimeSourceCalibrationRatio | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1.10 | Integer32 | read-write | The configured calibration offset in ppm compared to the nominal value of of the one-way (i.e. remote to local) to round trip time ratio. The nominal value of the ratio is 1/2, which is equivalent to a value of 0. |
| I32 dtmTimeSourceCalibrationReference | 1.3.6.1.4.1.2928.6.2.4.1.7.5 | Integer32 | read-write | The index of the dtmTimeSourceEntry of the time source that is used as calibration reference. The special value 0 is used if the field is not set, and means that the node clock is used as reference. |
| I32 dtmTimeSourceCalibrationTimeError | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1.9 | Integer32 | read-only | The time error in nanoseconds of the time source relative the calibration reference. The value 0 is used when the time error is not available. |
| dtmTimeSourceEntry | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1 | not-accessible | An entry in the time source table. | |
| I32 dtmTimeSourceIndex | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1.1 | Integer32 | not-accessible | Index in the dtmTimeSourceTable. |
| STR dtmTimeSourceName | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1.2 | DisplayString | read-only | The name of the time source. |
| INT dtmTimeSourceOperStatus | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1.4 | INTEGER | read-only | The actual state of the time source. The value should follow the state of the Administrative Status (dtmIfAdminStatus) unless something fails (dtmTimeSourceOperStatus=down), `dormant' if another time source is the active time source or be `absent' if the associated interface is not present. |
| NUM dtmTimeSourceRef | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1.6 | RowPointer | read-only | A reference to the time interface that provides the time source represented by this entry. The value .0.0 is used when no such reference is available. |
| U32 dtmTimeSourceRoundTripTime | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1.7 | Unsigned32 | read-only | The round trip time in nanoseconds for sending data to the peer of the time interface providing this time source and back. The value 0 is used, the round trip time is not available. |
| dtmTimeSourceTable | 1.3.6.1.4.1.2928.6.2.4.1.7.6 | not-accessible | A conceptual table containing time sources associated to time transfer capable interfaces. | |
| I32 dtmTimeSourceTimeError | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1.8 | Integer32 | read-only | The time error in nanoseconds of the time source relative the node clock. The value 0 is used when the time error is not available. |
| INT dtmTimeSourceType | 1.3.6.1.4.1.2928.6.2.4.1.7.6.1.5 | INTEGER | read-only | The type of time interface that provides the time source represented by this entry. dsyp(1) A DTM synchronization source (dsyp) represents a DTM interface timing source and the synchronization control information is distributed using the DTM Synchronization Protocol (DSYP). sqc(2) A squelchable clock (sqc) represents a clock interface that squelches its output to announce that it can not provide a source at the expected quality level. ssm(3) An SSM clock (ssm) represents a clock interface that also transports the Quality Level (QL) as a 4-bit Synchronization Signal Marker (SSM). internal(4) An internal clock (internal) represents a holdover clock that is internal to the node. |
