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.

DESCRIPTION
"Initial version of this MIB module."
::= { ciscoMgmt 130 }
DmtOverheadFraming ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"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."

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)."

DESCRIPTION
"One of the three parameters that affects FEC operation; the

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."

DESCRIPTION
"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."

MAX-ACCESS read-create
STATUS current
DESCRIPTION
"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."

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."

DESCRIPTION
"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
