Description: Defines DS3/T3 interface management objects for framing, line status, and performance per RFC 1407.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is RFC1407-MIB?

RFC1407-MIB (formally published as part of RFC 3896, superseding the original RFC 1407) is a vendor-neutral IETF standards MIB that defines managed objects for DS3 and E3 digital transmission interfaces, common in WAN and carrier-grade equipment. It exposes interface configuration data (line type, line coding, send code, circuit identifier, loopback configuration) as well as line status and time-interval-based performance statistics used for fault and performance monitoring. Its central monitoring use is hardware/line status: dsx3LineStatus reports real-time alarm and failure conditions on the physical DS3/E3 circuit, while dsx3TimeElapsed and dsx3ValidIntervals support historical performance-interval tracking, and ds3Traps deliver asynchronous notifications when line conditions change. It is tightly coupled to the standard IF-MIB, since DS3/E3 interfaces are indexed via ifIndex (dsx3IfIndex) and interface-generic counters are expected to be read alongside this MIB, and engineers pulling up the RFC1407-MIB reference documentation should note it now points to RFC 3896 rather than the original, obsoleted RFC 1407 text. It is typically deployed on carrier-class routers, channel banks, and access multiplexers terminating DS3/E3 leased lines or trunks.

IPNetwork Monitor allows you to monitor SNMP objects defined in RFC1407-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

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
router or access multiplexer with DS3/E3 WAN interfaces

Monitoring Examples

An administrator would poll dsx3ConfigTable/dsx3ConfigEntry, keyed by dsx3LineIndex and dsx3IfIndex, to check dsx3LineType, dsx3LineCoding, and dsx3LoopbackConfig for a DS3 circuit, then monitor dsx3LineStatus for bit-mapped alarm conditions such as loss of signal or AIS. Tracking dsx3TimeElapsed against dsx3ValidIntervals lets an operator correlate performance counters to a specific 15-minute interval when analyzing a burst of errors. Receiving a ds3Traps notification alongside a non-zero dsx3LineStatus would indicate the DS3 line has entered an alarm state requiring carrier or hardware investigation.

What Can Be Monitored

DS3/E3 line status and alarms
line type and coding configuration
loopback configuration
performance interval elapsed time
circuit identifier

dsx3FracTable	1.3.6.1.2.1.10.30.13		not-accessible	This table is deprecated in favour of using ifStackTable. Implementation of this table was optional. It was designed for those systems dividing a DS3/E3 into channels containing different data streams that are of local interest. The DS3/E3 fractional table identifies which DS3/E3 channels associated with a CSU are being used to support a logical interface, i.e., an entry in the interfaces table from the Internet- standard MIB. For example, consider a DS3 device with 4 high speed links carrying router traffic, a feed for voice, a feed for video, and a synchronous channel for a non-routed protocol. We might describe the allocation of channels, in the dsx3FracTable, as follows: dsx3FracIfIndex.2. 1 = 3 dsx3FracIfIndex.2.15 = 4 dsx3FracIfIndex.2. 2 = 3 dsx3FracIfIndex.2.16 = 6 dsx3FracIfIndex.2. 3 = 3 dsx3FracIfIndex.2.17 = 6 dsx3FracIfIndex.2. 4 = 3 dsx3FracIfIndex.2.18 = 6 dsx3FracIfIndex.2. 5 = 3 dsx3FracIfIndex.2.19 = 6 dsx3FracIfIndex.2. 6 = 3 dsx3FracIfIndex.2.20 = 6 dsx3FracIfIndex.2. 7 = 4 dsx3FracIfIndex.2.21 = 6 dsx3FracIfIndex.2. 8 = 4 dsx3FracIfIndex.2.22 = 6 dsx3FracIfIndex.2. 9 = 4 dsx3FracIfIndex.2.23 = 6 dsx3FracIfIndex.2.10 = 4 dsx3FracIfIndex.2.24 = 6 dsx3FracIfIndex.2.11 = 4 dsx3FracIfIndex.2.25 = 6 dsx3FracIfIndex.2.12 = 5 dsx3FracIfIndex.2.26 = 6 dsx3FracIfIndex.2.13 = 5 dsx3FracIfIndex.2.27 = 6 dsx3FracIfIndex.2.14 = 5 dsx3FracIfIndex.2.28 = 6 For dsx3M23, dsx3 SYNTRAN, dsx3CbitParity, and dsx3ClearChannel there are 28 legal channels, numbered 1 through 28. For e3Framed there are 16 legal channels, numbered 1 through 16. The channels (1..16) correspond directly to the equivalently numbered time-slots.

NUM dsx3LineIndex	1.3.6.1.2.1.10.30.5.1.1	InterfaceIndex	read-only	This object should be made equal to ifIndex. The next paragraph describes its previous usage. Making the object equal to ifIndex allows proper use of ifStackTable. Previously, this object was the identifier of a DS3/E3 Interface on a managed device. If there is an ifEntry that is directly associated with this and only this DS3/E3 interface, it should have the same value as ifIndex. Otherwise, number the dsx3LineIndices with an unique identifier following the rules of choosing a number that is greater than ifNumber and numbering the inside interfaces (e.g., equipment side) with even numbers and outside interfaces (e.g., network side) with odd numbers.
INT dsx3LineLength	1.3.6.1.2.1.10.30.5.1.13	INTEGER	read-write	The length of the ds3 line in meters. This object provides information for line build out circuitry if it exists and can use this object to adjust the line build out.
INT dsx3LineStatus	1.3.6.1.2.1.10.30.5.1.10	INTEGER	read-only	This variable indicates the Line Status of the interface. It contains loopback state information and failure state information. The dsx3LineStatus is a bit map represented as a sum, therefore, it can represent multiple failures and a loopback (see dsx3LoopbackConfig object for the type of loopback) simultaneously. The dsx3NoAlarm must be set if and only if no other flag is set. If the dsx3loopbackState bit is set, the loopback in effect can be determined from the dsx3loopbackConfig object. The various bit positions are: 1 dsx3NoAlarm No alarm present 2 dsx3RcvRAIFailure Receiving Yellow/Remote Alarm Indication 4 dsx3XmitRAIAlarm Transmitting Yellow/Remote Alarm Indication 8 dsx3RcvAIS Receiving AIS failure state 16 dsx3XmitAIS Transmitting AIS 32 dsx3LOF Receiving LOF failure state 64 dsx3LOS Receiving LOS failure state 128 dsx3LoopbackState Looping the received signal 256 dsx3RcvTestCode Receiving a Test Pattern 512 dsx3OtherFailure any line status not defined here 1024 dsx3UnavailSigState Near End in Unavailable Signal State 2048 dsx3NetEquipOOS Carrier Equipment Out of Service
NTF dsx3LineStatusChange	1.3.6.1.2.1.10.30.15.0.1			A dsx3LineStatusChange trap is sent when the value of an instance of dsx3LineStatus changes. It can be utilized by an NMS to trigger polls. When the line status change results in a lower level line status change (i.e., ds1), then no traps for the lower level are sent.
INT dsx3LineStatusChangeTrapEnable	1.3.6.1.2.1.10.30.5.1.15	INTEGER	read-write	Indicates whether dsx3LineStatusChange traps should be generated for this interface.

The type of interface affects the interpretation of the usage and error statistics. The rate of DS3 is 44.736 Mbps and E3 is 34.368 Mbps. The dsx3ClearChannel value means that the C-bits are not used except for sending/receiving AIS. The values, in sequence, describe: TITLE: SPECIFICATION: dsx3M23 ANSI T1.107-1988 dsx3SYNTRAN ANSI T1.107-1988 dsx3CbitParity ANSI T1.107a-1990 dsx3ClearChannel ANSI T1.102-1987 e3Framed CCITT G.751 e3Plcp ETSI T/NA(91)18 dsx3M13 ANSI T1.107a-1990.
INT dsx3LoopbackConfig	1.3.6.1.2.1.10.30.5.1.9	INTEGER	read-write	This variable represents the desired loopback configuration of the DS3/E3 interface. The values mean: dsx3NoLoop Not in the loopback state. A device that is not capable of performing a loopback on the interface shall always return this as its value. dsx3PayloadLoop The received signal at this interface is looped through the device. Typically the received signal is looped back for retransmission after it has passed through the device's framing function. dsx3LineLoop The received signal at this interface does not go through the device (minimum penetration) but is looped back out. dsx3OtherLoop Loopbacks that are not defined here. dsx3InwardLoop The sent signal at this interface is looped back through the device. dsx3DualLoop Both dsx1LineLoop and dsx1InwardLoop will be active simultaneously.
INT dsx3LoopbackStatus	1.3.6.1.2.1.10.30.5.1.16	INTEGER	read-only	This variable represents the current state of the loopback on the DS3 interface. It contains information about loopbacks established by a manager and remotely from the far end. The dsx3LoopbackStatus is a bit map represented as a sum, therefore is can represent multiple loopbacks simultaneously. The various bit positions are: 1 dsx3NoLoopback 2 dsx3NearEndPayloadLoopback 4 dsx3NearEndLineLoopback 8 dsx3NearEndOtherLoopback 16 dsx3NearEndInwardLoopback 32 dsx3FarEndPayloadLoopback 64 dsx3FarEndLineLoopback
INT dsx3SendCode	1.3.6.1.2.1.10.30.5.1.7	INTEGER	read-write	This variable indicates what type of code is being sent across the DS3/E3 interface by the device. (These are optional for E3 interfaces.) Setting this variable causes the interface to begin sending the code requested. The values mean: dsx3SendNoCode sending looped or normal data dsx3SendLineCode sending a request for a line loopback dsx3SendPayloadCode sending a request for a payload loopback (i.e., all DS1/E1s in a DS3/E3 frame) dsx3SendResetCode sending a loopback deactivation request dsx3SendDS1LoopCode requesting to loopback a particular DS1/E1 within a DS3/E3 frame. The DS1/E1 is indicated in dsx3Ds1ForRemoteLoop. dsx3SendTestPattern sending a test pattern.
INT dsx3TimeElapsed	1.3.6.1.2.1.10.30.5.1.3	INTEGER	read-only	The number of seconds that have elapsed since the beginning of the near end current error- measurement period. If, for some reason, such as an adjustment in the system's time-of-day clock, the current interval exceeds the maximum value, the agent will return the maximum value.

INT dsx3TransmitClockSource	1.3.6.1.2.1.10.30.5.1.11	INTEGER	read-write	The source of Transmit Clock. loopTiming indicates that the recovered receive clock is used as the transmit clock. localTiming indicates that a local clock source is used or that an external clock is attached to the box containing the interface. throughTiming indicates that transmit clock is derived from the recovered receive clock of another DS3 interface.
INT dsx3ValidIntervals	1.3.6.1.2.1.10.30.5.1.4	INTEGER	read-only	The number of previous near end intervals for which data was collected. The value will be 96 unless the interface was brought online within the last 24 hours, in which case the value will be the number of complete 15 minute near end intervals since the interface has been online. In the case where the agent is a proxy, it is possible that some intervals are unavailable. In this case, this interval is the maximum interval number for which data is available.
