The is the MIB module that describes DS3 and E3 interfaces objects.

The DS3/E3 Configuration table.

An entry in the DS3/E3 Configuration table.

This object should be made equal to ifIndex. The next paragraph describes its previous usage. Making the object equal to ifIndex allows propoer 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.

This value for this object is equal to the value of ifIndex from the Interfaces table of MIB II (RFC 1213).

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.

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.

This variable indicates the variety of DS3 C-bit or E3 application implementing 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 [9] dsx3SYNTRAN ANSI T1.107-1988 [9] dsx3CbitParity ANSI T1.107a-1990 [9a] dsx3ClearChannel ANSI T1.102-1987 [8] e3Framed CCITT G.751 [12] e3Plcp ETSI T/NA(91)18 [13]. Enumeration: 'dsx3ClearChannel': 5, 'e3other': 6, 'dsx3CbitParity': 4, 'dsx3SYNTRAN': 3, 'dsx3other': 1, 'e3Plcp': 8, 'e3Framed': 7, 'dsx3M23': 2.

This variable describes the variety of Zero Code Suppression used on this interface, which in turn affects a number of its characteristics. dsx3B3ZS and e3HDB3 refer to the use of specified patterns of normal bits and bipolar violations which are used to replace sequences of zero bits of a specified length. Enumeration: 'dsx3B3ZS': 2, 'e3HDB3': 3, 'dsx3Other': 1.

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. Enumeration: 'dsx3SendLineCode': 2, 'dsx3SendTestPattern': 6, 'dsx3SendPayloadCode': 3, 'dsx3SendResetCode': 4, 'dsx3SendDS1LoopCode': 5, 'dsx3SendNoCode': 1.

This variable contains the transmission vendor's circuit identifier, for the purpose of facilitating troubleshooting.

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. Enumeration: 'dsx3NoLoop': 1, 'dsx3LineLoop': 3, 'dsx3OtherLoop': 4, 'dsx3DualLoop': 6, 'dsx3InwardLoop': 5, 'dsx3PayloadLoop': 2.

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

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. Enumeration: 'throughTiming': 3, 'loopTiming': 1, 'localTiming': 2.

The number of intervals in the range from 0 to dsx3ValidIntervals for which no data is available. This object will typically be zero except in cases where the data for some intervals are not available (e.g., in proxy situations).

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.

The value of MIB II's sysUpTime object at the time this DS3/E3 entered its current line status state. If the current state was entered prior to the last re-initialization of the proxy-agent, then this object contains a zero value.

Indicates whether dsx3LineStatusChange traps should be generated for this interface. Enumeration: 'disabled': 2, 'enabled': 1.

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

Indicates whether this ds3/e3 is channelized or unchannelized. The value of enabledDs1 indicates that this is a DS3 channelized into DS1s. The value of enabledDs3 indicated that this is a DS3 channelized into DS2s. Setting this object will cause the creation or deletion of DS2 or DS1 entries in the ifTable. Enumeration: 'disabled': 1, 'enabledDs2': 3, 'enabledDs1': 2.

Indicates which ds1/e1 on this ds3/e3 will be indicated in the remote ds1 loopback request. A value of 0 means no DS1 will be looped. A value of 29 means all ds1s/e1s will be looped.

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 throug h 28. For e3Framed there are 16 legal channels, numbered 1 through 16. The channels (1..16) correspond directly to the equivalently numbered time-slots.

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.
