Description
This MIB module serves as an enterprise-specific extension of the ADSL-LINE-MIB. The structure of this MIB module shadows the structure of the ADSL-LINE-MIB, table for table. The tables defined by this MIB module contain managed objects that meet the following criteria: 1) A managed object represents an attribute or characteristic specific to DMT (Digital Multi-Tone) modems. 2) The ADSL-DMT-LINE-MIB does not already contain a managed object representing the same information as a managed object. Observe that entries contained by the tables in this MIB module do not augment the corresponding entries in the ADSL-LINE-MIB, as every modem represented by the ADSL-LINE-MIB is not necessarily a DMT modem. Also observe that entries contained by the tables in this MIB module do not augment the corresponding entries in the ADSL-DMT-LINE-MIB, as this assumes that the ADSL-DMT-LINE-MIB defines tables that correspond to every table defined by the ADSL-LINE-MIB. At this time, this assumption does not hold true. *** DEFINITIONS *** AGGREGATE DATA RATE Data rate transmitted by an ADSL system in any one direction. This includes both net data rates and overhead used by the system, including: - EOC - AOC (ADSL Overhead Control channel) - CRC (Cyclic Redundancy Check) check bytes - fixed indicator bits for OAM (Operatings, Administration, and Maintenance) - synchronization control bytes - capacity for bearer channel synchronization control BEARER CHANNEL A user data stream of a specific data rate that is transported transparently by an ADSL system over one of the simplex channels (i.e., AS0, AS1, AS2, or AS3) or one of the duplex channels (i.e., LS0, LS1, or LS2). BIN DMT line coding divides the frequency spectrum above the voice band of a line (i.e., 0-4 kHz) into 255 sub-carriers, each supporting 4.3125 kHz of bandwidth. A 'bin' refers to a single sub-carrier. DATA SYMBOL RATE The average symbol rate (after allowing for the overhead of the sync symbol) at which symbols carrying data are transmitted; that is, 4000 symbols/second. DOWNSTREAM The flow of data in the direction from the ATU-C to ATU-R. LINE RATE The total data rate supported by a line; that is, (sum of b(i) for all i) * 4 kbps. MARGIN (also referred to as 'SNR margin') The difference between the SNR of the received signal and the SNR required to provide a BER of 10E-7. NET DATA RATE The data rate that is available for user data in any one direction; for the downstream direction this is the sum of the simplex and duplex bearer channel rates. SPLITTER Filters that separate the high frequency signals (ADSL) from the voice band signals; (frequently called POTS splitters even though the voice band signals may comprise more than just POTS). SYMBOL The number of bits the transmitter is capable of multiplexing and modulating over all the bins in a single signalling interval. SYMBOL RATE The rate at which all symbols, including the sync symbol, are transmitted; that is, (69/68) * 4000 symbols/sec; contrasted with the data symbol rate. TOTAL DATA RATE The aggregate data rate (q.v.) plus Reed-Solomon FEC overhead. UPSTREAM The flow of data in the direction from the ATU-R to ATU-C. *** ABBREVIATIONS, ACRONYMS, AND SYMBOLS *** ADSL - Asymmetric Digital Subscriber Line. ATM - Asynchronous Transfer Mode. ATU-C - ADSL Transceiver Unit, Central Office end. ATU-R - ADSL Transceiver Unit, Remote terminal end. b(i) - the number of bits (i.e., constellation size) modulated on bin i. BER - Bit Error Ratio. DMT - Discrete MultiTone. DSL - Digital Subscriber Line. EOC - Embedded Operations Channel. FEC - Forward Error Correction. SNR - Signal-to-Noise Ratio. STM - Synchronous Transfer Mode.

| DmtCodewordSize TEXTUAL-CONVENTION One of the three parameters that affects FEC operation; the number of ADSL symbols per FEC codeword. The FEC size also affects FEC operation. The interleave depth also affects FEC operation on an interleaved channel (see the ADSL-LINE-MIB, specifically adslAtucChanConfMaxInterleaveDelay and adslAturChanConfMaxInterleaveDelay). The following constraints apply: - This value is always '1' when performing the FEC operation on a fast buffer. - When performing the FEC operation on an interleaved buffer, the specification does not require a codeword size greater than '1' when the interleave depth is set to '1'. - if DmtCodeWordSize is positive, it represents the actual number of symbols per codeword. If DmtCodeWordSize is negative, it represents the exponent value in a power of 2. For example, if DmtCodeWordSize is equal to -1, then the number of symbols per codeword would be equal to 2^^-1 = 1/2. | current | |||
| DmtFecSize TEXTUAL-CONVENTION One of the three parameters that affects FEC operation; the number of FEC redundancy bytes per Reed-Solomon codeword. The codeword size also affects FEC operation. The interleave depth also affects FEC operation on an interleaved channel (see the ADSL-LINE-MIB, specifically adslAtucChanConfMaxInterleaveDelay and adslAturChanConfMaxInterleaveDelay). | current | |||
| DmtOverheadFraming TEXTUAL-CONVENTION There exist two types of ADSL framing: full overhead and reduced overhead. Furthermore, there exist two versions of full overhead and two versions of reduced overhead. The table below defines the four resulting framing structures: 'structure0' Full overhead framing with asynchronous bit-to-modem timing (enabled synchronization control mechanism). 'structure1' Full overhead framing with synchronous bit-to-modem timing (disabled synchronization control mechanism). 'structure2' Reduced overhead framing with separate fast and sync bytes in fast and interleaved latency buffers respectively (64 kbps framing overhead). 'structure3' Reduced overhead framing with merged fast and sync byte, using either the fast or interleaved latency buffer (32 kbps framing overhead). During the training sequence, the ATU-C shall indicate the highest framing structure number that it supports. It is implied that if the ATU-C indicates it supports framing structure k, it also supports all framing structures 0 to k-1. If during the training sequence the ATU-R indicates a lower framing structure than that specified by the ATU-C, the ATU-C shall fall back to the framing structure number indicated by the ATU-R. Management requirements drive the determination of overhead, full or reduced. Full overhead provides more bandwidth to the EOC channel, thereby enabling higher polling rates. However, reduced overhead provides enough bandwidth to satisfy typical applications. If an ADSL line is supporting an ATM link, then a structure must be chosen that disables synchronization control. If an ADSL line is supporting an STM link, and the ADSL line interface has a clock tightly coupled to the stratum clock, then synchronization control is not necessary. If an ADSL line is supporting an STM link, and the ADSL line interface is driven by a clock that has no relationship with the stratum clock, then a struture that enables synchronization control is necessary. | current |

| cAdslLineDmtConfOperatingMode OBJECT-TYPE This object specifies the line operating mode being employed by the ADSL line. An ADSL line uses of one of two operating modes: - Automatic An ATU-C that employs this operating mode automatically detects the capabilities of the ATU-R and utilizes either a startup sequence specified by G.992.1, G.992.2, or T1.413-1998. This line operating mode is the default for an ADSL line. - Splitterless This operating mode should no longer be used. It is equivalent to the G.992.2 selection. Selecting this mode will automatically map to the G992.2 mode. It is appropriate in this case that both the ATU-C and ATU-R support 'heavy' capability but the ATU-C side wishes to force 'lite' operation. Selecting this mode will automatically convert to the G992.2 mode. - G992.1 This operating mode forces the used of the G994.1 startup sequence and compliance to G992.1 operation. - G992.2 This operating mode forces the use of the G994.1 startup sequence and compliance to G992.2 operation. It is appropriate in this case that both the ATU-C and ATU-R support 'heavy' capability but the ATU-C side wishes to force 'lite' operation. - T1.413 This operating mode forces the ATU-R to use the T1.413-1998 startup sequence. | 1.3.6.1.4.1.9.9.130.1.14.1.1 | INTEGER {automatic(1), splitterless(2), g992Dot1(3), g992Dot2(4), t1Dot413(5)} | read-create | current |
| cAdslLineDmtConfTrainingMode OBJECT-TYPE This object specifies the mode employed by the ATU-C and ATU-R when training against each other. One of two training modes can be employed: - Standard An ATU-C initiates a training sequence using the method defined by G.992.1, G.992.2, or T1.413-1998. This training mode is the default for ADSL modems. - Fast An ATU-C initiates a vendor-specific training sequence that can possibly provide a shorter training sequence. | 1.3.6.1.4.1.9.9.130.1.14.1.2 | INTEGER {standard(1), fast(2)} | read-create | current |
| cAdslAtucDmtConfFastFecSize OBJECT-TYPE This object specifies the initial number of FEC redundancy bytes the ATU-C appends to downstream frames transmitted over the fast channel during the training sequence. The ATU-C can fallback from this value depending on the aggregate data rate achieved during training. It is desirable to choose a large FEC size, thereby increasing the chance of being able to correct errors in the data delivered by a frame. However, additional FEC redundancy bytes increases frame overhead, and thus frame latency. | 1.3.6.1.4.1.9.9.130.1.14.1.3 | DmtFecSize | read-create | current |
| cAdslAtucDmtConfInterleaveFecSize OBJECT-TYPE This object specifies the initial number of FEC redundancy bytes the ATU-C appends to downstream frames transmitted over the interleaved channel during the training sequence. The ATU-C can fallback from this value depending on the aggregate data rate achieved during training. It is desirable to choose a large FEC size, thereby increasing the chance of being able to correct errors in the data delivered by a frame. However, additional FEC redundancy bytes increases frame overhead, and thus frame latency. The value of this object must be a integral multiple of the value of cAdslAtucDmtConfCodewordSize. | 1.3.6.1.4.1.9.9.130.1.14.1.4 | DmtFecSize | read-create | current |
| cAdslAtucDmtConfCodewordSize OBJECT-TYPE This object specifies the number of symbols per codeword being used by the ATU-C for downstream messages on an interleaved channel during the training sequence. The ATU-C can fallback from this value based on the aggregate data rate achieved during training. It is desirable to choose a large codeword size to minimize overhead. However, increasing the codeword size increases the possibility of not being able to correct errors in the data delivered by a frame. | 1.3.6.1.4.1.9.9.130.1.14.1.5 | DmtCodewordSize | read-create | current |
| cAdslAtucDmtConfOverheadFraming OBJECT-TYPE This object specifies the overhead framing structure which the ATU-C will request when establishing a link with the ATU-R. The value of 'structure0' is not valid. | 1.3.6.1.4.1.9.9.130.1.14.1.6 | DmtOverheadFraming | read-create | current |
| cAdslAtucDmtConfBitSwapEnabled OBJECT-TYPE This object specifies whether the ATU-C performs bitswapping. Bitswapping attempts to maintain an acceptable margin for each bin; equalizing the margin across all bins through bit reallocation, thereby maximizing error performance. The ATU-C performs bitswapping by monitoring the margin measured for each bin by the transmitter: 1) If a bin's margin falls below 'target' and the difference, between the margin and 'target' exceeds 'thresh(f)', then the ATU-C marks the bin as a 'from' bin. 2) If a bin's margin exceeds 'target' and the difference between the margin and 'target' exceeds 'thresh(t)', then the ATU-C marks the bin as a 'to' bin. Where: 'target' = adslAtucConfTargetSnrMgn 'thresh(f)' = cAdslAtucDmtConfBitSwapFrom 'thresh(t)' = cAdslAtucDmtConfBitSwapTo The ATU-C attempts to equalize the margin across the bins by swapping bits out of bins marked 'from' into bins marked 'to'. When the ATU-C swaps a bit out of bin, it decreases its b(i). Thus, the bins constellation is smaller, which increases its margin. When the ATU-C swaps a bit into a bin, it increases its b(i). Thus, the bins constellation is larger, which decreases its margin. In addition, the ATU-R may optionally implement its own monitoring capability. The ATU-R uses this information to request the ATU-C to perform bitswapping. When this object is 'true', the ATU-C must be prepared to accept and properly handle bitswap requests from the ATU-R. While bitswapping has its obvious advantages, bitswapping can have undesirable side effects. It can introduce errors on lines prone to impulse noise. In this case, it may be desirable to disable bitswapping. | 1.3.6.1.4.1.9.9.130.1.14.1.7 | TruthValue | read-create | current |
| cAdslAtucDmtConfBitSwapFrom OBJECT-TYPE Bitswapping attempts to maintain an acceptable margin for each bin; equalizing the margin across all bins through bit reallocation, thereby maximizing error performance. The ATU-C performs bitswapping by monitoring the margin measured for each bin by the transmitter. If a bin's margin falls below adslAtucConfTargetSnrMgn and the difference between the margin and adslAtucConfTargetSnrMgn exceeds the value of this object, then the ATU-C marks a bin as a 'from' bin. The ATU-C attempts to equalize the margin across the bins by swapping bits out of bins marked 'from' into bins marked 'to'. When the ATU-C swaps a bit out of bin, it decreases its b(i). Thus, the bins constellation is smaller. which increases its margin. When the ATU-C swaps a bit into a bin, it increases its b(i). Thus, the bins constellation is larger, which decreases its margin. If this value is too small, then the ATU-C may frequently toggle the bit allocation on bins, and if impulse noise is present, this can cause errors. If this value is too large, then the ATU-C may not identify an adequate number of bins that it can swap bits 'from', thereby decreasing the chances for the ATU-C to equalize the margin across all the bins. Unequalized margin across all the bins translates into poor error performance. | 1.3.6.1.4.1.9.9.130.1.14.1.8 | Integer32 (1..9) | read-create | current |
| cAdslAtucDmtConfBitSwapTo OBJECT-TYPE Bitswapping attempts to maintain an acceptable margin for each bin; equalizing the margin across all bins through bit reallocation, thereby maximizing error performance. The ATU-C performs bitswapping by monitoring the margin measured for each bin by the transmitter. If a bin's margin exceeds adslAtucConfTargetSnrMgn and the difference between the margin and adslAtucConfTargetSnrMgn exceeds the value of this object, then the ATU-C marks a bin as a 'to' bin. The ATU-C attempts to equalize the margin across the bins by swapping bits out of bins marked 'from' into bins marked 'to'. When the ATU-C swaps a bit out of bin, it decreases its b(i). Thus, the bins constellation is smaller. which increases its margin. When the ATU-C swaps a bit into a bin, it increases its b(i). Thus, the bins constellation is larger, which decreases its margin. If this value is too small, then the ATU-C may frequently toggle the bit allocation on bins, and if impulse noise is present, this can cause errors. If this value is too large, then the ATU-C may not identify an adequate number of bins that it can swap bits 'to', thereby decreasing the chances for the ATU-C to equalize the margin across all the bins.

The ATU-C can force the ATU-R to fallback from this value depending on the aggregate data rate achieved during training. It is desirable to choose a large FEC size, thereby increasing the chance of being able to correct errors in the data delivered by a frame.

It is desirable to choose a large FEC size, thereby increasing the chance of being able to correct errors in the data delivered by a frame.

The request will be processed when cAdslDmtIfRqstStatus is set to pollNow (1). Setting this object will fail if the value of cAdslDmtIfRqstStatus is currently rqstInProgress (3).
