The MIB module to describe DS1, E1, DS2, and E2 interfaces objects. not-accessible current 1.3.6.1.2.1.10.18.6.1 An entry in the DS1 Configuration table. not-accessible current 1.3.6.1.2.1.10.18.7.1 An entry in the DS1 Current table. not-accessible current 1.3.6.1.2.1.10.18.8.1 An entry in the DS1 Interval table. not-accessible current 1.3.6.1.2.1.10.18.9.1 An entry in the DS1 Total table. not-accessible current 1.3.6.1.2.1.10.18.10.1 An entry in the DS1 Far End Current table. not-accessible current 1.3.6.1.2.1.10.18.11.1 An entry in the DS1 Far End Interval table. not-accessible current 1.3.6.1.2.1.10.18.12.1 An entry in the DS1 Far End Total table. not-accessible deprecated 1.3.6.1.2.1.10.18.13.1 An entry in the DS1 Fractional table. not-accessible current 1.3.6.1.2.1.10.18.16.1 An entry in the DS1 Channel Mapping table. There is an entry in this table corresponding to each ds1 ifEntry within any interface that is channelized to the individual ds1 ifEntry level. This table is intended to facilitate mapping from channelized interface / channel number to DS1 ifEntry. (e.g. mapping (DS3 ifIndex, DS1 Channel Number) -> ifIndex) While this table provides information that can also be found in the ifStackTable and dsx1ConfigTable, it provides this same information with a single table lookup, rather than by walking the ifStackTable to find the various constituent ds1 ifTable entries, and testing various dsx1ConfigTable entries to check for the entry with the applicable DS1 channel number. read-only current 1.3.6.1.2.1.10.18.6.1.1 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 and ds0/ds0bundle mibs. Previously, this object is the identifier of a DS1 Interface on a managed device. If there is an ifEntry that is directly associated with this and only this DS1 interface, it should have the same value as ifIndex. Otherwise, number the dsx1LineIndices 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. "d" read-only deprecated 1.3.6.1.2.1.10.18.6.1.2 This value for this object is equal to the value of ifIndex from the Interfaces table of MIB II (RFC 1213). "d" read-only current 1.3.6.1.2.1.10.18.6.1.3 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. read-only current 1.3.6.1.2.1.10.18.6.1.4 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. read-write current 1.3.6.1.2.1.10.18.6.1.5 This variable indicates the variety of DS1 Line implementing this circuit. The type of circuit affects the number of bits per second that the circuit can reasonably carry, as well as the interpretation of the usage and error statistics. The values, in sequence, describe: TITLE: SPECIFICATION: dsx1ESF Extended SuperFrame DS1 (T1.107) dsx1D4 AT&T D4 format DS1 (T1.107) dsx1E1 ITU-T Recommendation G.704 (Table 4a) dsx1E1-CRC ITU-T Recommendation G.704 (Table 4b) dsxE1-MF G.704 (Table 4a) with TS16 multiframing enabled dsx1E1-CRC-MF G.704 (Table 4b) with TS16 multiframing enabled dsx1Unframed DS1 with No Framing dsx1E1Unframed E1 with No Framing (G.703) dsx1DS2M12 DS2 frame format (T1.107) dsx1E2 E2 frame format (G.704) For clarification, the capacity for each E1 type is as listed below: dsx1E1Unframed - E1, no framing = 32 x 64k = 2048k dsx1E1 or dsx1E1CRC - E1, with framing, no signalling = 31 x 64k = 1984k dsx1E1MF or dsx1E1CRCMF - E1, with framing, signalling = 30 x 64k = 1920k For further information See ITU-T Recomm G.704 1 2 3 4 5 6 7 8 9 10 11 read-write current 1.3.6.1.2.1.10.18.6.1.6 This variable describes the variety of Zero Code Suppression used on this interface, which in turn affects a number of its characteristics. dsx1JBZS refers the Jammed Bit Zero Suppression, in which the AT&T specification of at least one pulse every 8 bit periods is literally implemented by forcing a pulse in bit 8 of each channel. Thus, only seven bits per channel, or 1.344 Mbps, is available for data. dsx1B8ZS refers to the use of a specified pattern of normal bits and bipolar violations which are used to replace a sequence of eight zero bits. ANSI Clear Channels may use dsx1ZBTSI, or Zero Byte Time Slot Interchange. E1 links, with or without CRC, use dsx1HDB3 or dsx1AMI. dsx1AMI refers to a mode wherein no zero code suppression is present and the line encoding does not solve the problem directly. In this application, the higher layer must provide data which meets or exceeds the pulse density requirements, such as inverting HDLC data. dsx1B6ZS refers to the user of a specifed pattern of normal bits and bipolar violations which are used to replace a sequence of six zero bits. Used for DS2. 1 2 3 4 5 6 7 read-write current 1.3.6.1.2.1.10.18.6.1.7 This variable indicates what type of code is being sent across the DS1 interface by the device. Setting this variable causes the interface to send the code requested. The values mean: dsx1SendNoCode sending looped or normal data dsx1SendLineCode sending a request for a line loopback dsx1SendPayloadCode sending a request for a payload loopback dsx1SendResetCode sending a loopback termination request dsx1SendQRS sending a Quasi-Random Signal (QRS) test pattern dsx1Send511Pattern sending a 511 bit fixed test pattern dsx1Send3in24Pattern sending a fixed test pattern of 3 bits set in 24 dsx1SendOtherTestPattern sending a test pattern other than those described by this object 1 2 3 4 5 6 7 8 read-write current 1.3.6.1.2.1.10.18.6.1.8 This variable contains the transmission vendor's circuit identifier, for the purpose of facilitating troubleshooting. "255a" read-write current 1.3.6.1.2.1.10.18.6.1.9 This variable represents the desired loopback configuration of the DS1 interface. Agents supporting read/write access should return inconsistentValue in response to a requested loopback state that the interface does not support. The values mean: dsx1NoLoop 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. dsx1PayloadLoop 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. dsx1LineLoop The received signal at this interface does not go through the device (minimum penetration) but is looped back out. dsx1OtherLoop Loopbacks that are not defined here. dsx1InwardLoop The transmitted signal at this interface is looped back and received by the same interface. What is transmitted onto the line is product dependent. dsx1DualLoop Both dsx1LineLoop and dsx1InwardLoop will be active simultaneously. 1 2 3 4 5 6 read-only current 1.3.6.1.2.1.10.18.6.1.10 This variable indicates the Line Status of the interface. It contains loopback, failure, received 'alarm' and transmitted 'alarms information. The dsx1LineStatus is a bit map represented as a sum, therefore, it can represent multiple failures (alarms) and a LoopbackState simultaneously. dsx1NoAlarm must be set if and only if no other flag is set. If the dsx1loopbackState bit is set, the loopback in effect can be determined from the dsx1loopbackConfig object. The various bit positions are: 1 dsx1NoAlarm No alarm present 2 dsx1RcvFarEndLOF Far end LOF (a.k.a., Yellow Alarm) 4 dsx1XmtFarEndLOF Near end sending LOF Indication 8 dsx1RcvAIS Far end sending AIS 16 dsx1XmtAIS Near end sending AIS 32 dsx1LossOfFrame Near end LOF (a.k.a., Red Alarm) 64 dsx1LossOfSignal Near end Loss Of Signal 128 dsx1LoopbackState Near end is looped 256 dsx1T16AIS E1 TS16 AIS 512 dsx1RcvFarEndLOMF Far End Sending TS16 LOMF 1024 dsx1XmtFarEndLOMF Near End Sending TS16 LOMF 2048 dsx1RcvTestCode Near End detects a test code 4096 dsx1OtherFailure any line status not defined here 8192 dsx1UnavailSigState Near End in Unavailable Signal State 16384 dsx1NetEquipOOS Carrier Equipment Out of Service 32768 dsx1RcvPayloadAIS DS2 Payload AIS 65536 dsx1Ds2PerfThreshold DS2 Performance Threshold Exceeded read-write current 1.3.6.1.2.1.10.18.6.1.11 'none' indicates that no bits are reserved for signaling on this channel.

'loopTiming' indicates that the recovered re- ceive clock is used as the transmit clock. 'localTiming' indicates that a local clock source is used or when an external clock is attached to the box containing the interface. 'throughTiming' indicates that recovered re- ceive clock from another interface is used as the transmit clock. 1 2 3 read-write current 1.3.6.1.2.1.10.18.6.1.13 This bitmap describes the use of the facili- ties data link, and is the sum of the capabili- ties. Set any bits that are appropriate: other(1), dsx1AnsiT1403(2), dsx1Att54016(4), dsx1FdlNone(8) 'other' indicates that a protocol other than one following is used. 'dsx1AnsiT1403' refers to the FDL exchange recommended by ANSI. 'dsx1Att54016' refers to ESF FDL exchanges. 'dsx1FdlNone' indicates that the device does not use the FDL. read-only current 1.3.6.1.2.1.10.18.6.1.14 The number of intervals in the range from 0 to dsx1ValidIntervals for which no data is available.

This object is only useful if the interface has configurable line build out circuitry. read-only current 1.3.6.1.2.1.10.18.6.1.16 The value of MIB II's sysUpTime object at the time this DS1 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. read-write current 1.3.6.1.2.1.10.18.6.1.17 Indicates whether dsx1LineStatusChange traps should be generated for this interface. 1 2 read-only current 1.3.6.1.2.1.10.18.6.1.18 This variable represents the current state of the loopback on the DS1 interface. It contains information about loopbacks established by a manager and remotely from the far end. The dsx1LoopbackStatus is a bit map represented as a sum, therefore is can represent multiple loopbacks simultaneously. The various bit positions are: 1 dsx1NoLoopback 2 dsx1NearEndPayloadLoopback 4 dsx1NearEndLineLoopback 8 dsx1NearEndOtherLoopback 16 dsx1NearEndInwardLoopback 32 dsx1FarEndPayloadLoopback 64 dsx1FarEndLineLoopback read-only current 1.3.6.1.2.1.10.18.6.1.19 This variable represents the channel number of the DS1/E1 on its parent Ds2/E2 or DS3/E3. A value of 0 indicated this DS1/E1 does not have a parent DS3/E3. read-write current 1.3.6.1.2.1.10.18.6.1.20 Indicates whether this ds1/e1 is channelized or unchannelized. The value of enabledDs0 indicates that this is a DS1 channelized into DS0s. The value of enabledDs1 indicated that this is a DS2 channelized into DS1s. Setting this value will cause the creation or deletion of entries in the ifTable for the DS0s that are within the DS1. 1 2 3 read-only current 1.3.6.1.2.1.10.18.7.1.1 The index value which uniquely identifies the DS1 interface to which this entry is applicable.
