What Is Wellfleet-DSUCSU-MIB?

Wellfleet-DSUCSU-MIB is a vendor MIB from Wellfleet Communications (later Bay Networks/Nortel) covering integrated Digital Service Unit/Channel Service Unit modules on Wellfleet routers, the hardware that terminates a digital WAN circuit and interfaces to the carrier's line. It exposes configuration data such as line conditioning and clocking mode settings, along with status/statistics objects for line errors and signal quality. Its monitoring focus is squarely on WAN interface hardware status: an operator checks DSU/CSU line statistics and alarm indicators to detect physical-layer problems such as loss of signal, clocking mismatches, or line errors before they escalate to a full circuit outage. It parallels concepts in standard IETF DSU/CSU-related interface MIBs though implemented as a Wellfleet-specific module. It is typically deployed on legacy Wellfleet/Bay Networks routers with integrated DSU/CSU WAN interface modules in enterprise leased-line environments. Engineers can download the Wellfleet-DSUCSU-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Wellfleet-DSUCSU-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

legacy digital WAN interface hardware

Monitoring Examples

An administrator would poll the DSU/CSU line status and error-statistics objects to confirm clocking source and line conditioning settings match the carrier's circuit requirements, and a rising line-error or loss-of-signal counter would reveal a bad cable, clocking mismatch, or carrier-side circuit fault. No sample objects were listed in the source excerpt, so specific table/object names are inferred from standard DSU/CSU line-status concepts rather than taken verbatim from the MIB.

What Can Be Monitored

line conditioning/clocking configuration
line error counters
loss-of-signal status

OIDs

OID symbolic	OID numeric	Type	Access	Description
INT wfDsuCsu64KTxMonitor	1.3.6.1.4.1.18.3.4.30.1.1.9	INTEGER	read-write	This signal is used in 64K Clear Channel mode to suppress customer data in the event that the data duplicates a network control code. A setting of enabled(1) suppresses customer data. A setting of disabled(2) allows all customer data through, which could potentially put the other end into a loop if the data duplicates a network control code.
CTR wfDsuCsuCqmsLaErrors	1.3.6.1.4.1.18.3.4.30.1.1.16	Counter	read-only	Indicates the total number of seconds that the line was not in service in the last window of size wfDsuCsuCqmsLaWindow.
INT wfDsuCsuCqmsLaPollRate	1.3.6.1.4.1.18.3.4.30.1.1.17	INTEGER	read-write	Indicates the number of seconds between polls for line status from the DsuCsu. A value of 1 forces polling every second. A value of 60 forces polling every minute.
INT wfDsuCsuCqmsLaWindow	1.3.6.1.4.1.18.3.4.30.1.1.15	INTEGER	read-write	Indicates the number of minutes within the window in which the availability of the line (network) is to be calculated. The availability of the line is an indication of the percentage of time the line has been in service. It is calculated as follows: (((wfDsuCsuCqmsLaWindow60) - (wfDsuCsuCqmsLaErrCntwfDsuCsuCqmsLaPollRate))/ wfDsuCsuCqmsLaWindow*60)
INT wfDsuCsuCqmsReset	1.3.6.1.4.1.18.3.4.30.1.1.18	INTEGER	read-write	Resets the CQMS counters to their default values. For Line Availability, wfDsuCsuCqmsLaErrCnt is reset.
CTR wfDsuCsuFrameErrors	1.3.6.1.4.1.18.3.4.30.1.1.20	Counter	read-only	The number of seconds in which the unit was out of frame with the Telco. This is only applicable in 64K mode. The counter is incremented whenever a sample within a second indicated the unit was out of frame.
STR wfDsuCsuHardRev	1.3.6.1.4.1.18.3.4.30.1.1.5	DisplayString	read-only	Displays the Hardware Revision of the DSU CSU card.
INT wfDsuCsuIfConnector	1.3.6.1.4.1.18.3.4.30.1.1.3	INTEGER	read-only	Instance ID Connector, filled in by the driver.
INT wfDsuCsuIfDelete	1.3.6.1.4.1.18.3.4.30.1.1.1	INTEGER	read-write	Create/Delete parameter
wfDsuCsuIfEntry	1.3.6.1.4.1.18.3.4.30.1.1		not-accessible	An entry in the DSU CSU IF table
INT wfDsuCsuIfSlot	1.3.6.1.4.1.18.3.4.30.1.1.2	INTEGER	read-only	Instance ID Slot, filled in by driver
wfDsuCsuIfTable	1.3.6.1.4.1.18.3.4.30.1		not-accessible	DSU CSU line record.
NTF wfDsuCsuIfTrap	1.3.6.1.4.1.18.3.4.30.0.1			Indicates a change in the status of the line. The value returned in the trap will indicate the current state as defined in wfDsuCsuServiceStatus.
INT wfDsuCsuInitState	1.3.6.1.4.1.18.3.4.30.1.1.22	INTEGER	read-only	Indictes the state of the DSU/CSU initialization sequence. The state will indicate if the DSU/CSU has been initialized and is in the monitor state polling the card for line condition, or in the *loopback state running a user-initiated loopback
CTR wfDsuCsuLOLErrors	1.3.6.1.4.1.18.3.4.30.1.1.21	Counter	read-only	The number of seconds in which the unit has detected that no signal is present on the line, and/or no line is present.
CTR wfDsuCsuOOSErrors	1.3.6.1.4.1.18.3.4.30.1.1.19	Counter	read-only	The number of seconds in which Out of Service control codes were received from the Telco. The counter is incremented whenever a sample within a second indicated the unit received an out of service control code.
INT wfDsuCsuOpMode	1.3.6.1.4.1.18.3.4.30.1.1.6	INTEGER	read-write	Identifies the type of telco service that the DSU CSU is connected to. Opmode should be set to dds1-56kbps (1) when connected to a DDS1 56 Kbps line. Opmode should be set to cc-64kbps (2) when connected to a Clear Channel 64Kbps line.
INT wfDsuCsuOpState	1.3.6.1.4.1.18.3.4.30.1.1.10	INTEGER	read-only	Indicates the current operating state of the DSU CSU card.

STR wfDsuCsuSoftRev	1.3.6.1.4.1.18.3.4.30.1.1.4	DisplayString	read-only	Displays the Software Revision of the DSU CSU card.
INT wfDsuCsuTxClkSelect	1.3.6.1.4.1.18.3.4.30.1.1.7	INTEGER	read-write	Default timing, or clock, source for transmiting data to the network. There must be only one source on a DDS line. Timing should always be slave (1) when connected to a network. Timing should be set to master (2) on either end of a private-wire configuration, with the other end being set to slave (1).
