`Union point to 11.413 as a reference
`for their ADSL standards.
`For modem designers, a careful re-
`view of 11.413 is essential when eval-
`uating ADSL chipsets. In particular.
`understanding the different cate-
`gories of the 11.413 standard is cru-
`cial in determining how an ADS]. mo
`dem will actually perform in the field.
`
`ing up the transmit signal strength—
`is no longer under consideration be-
`cause of concerns about excessive
`crosstalk with other wires in the
`same binder group.
`To ensure compatibility bchveen
`Category I and II modems. various de-
`vice options and setup information are
`transmitted at startup. This procedure
`allows the device at each end of the
`wire to be aware of the other’s capabil-
`ities and to adjust itself accordingly.
`A Category II modern falls back to
`basic Category I operation when nec-
`essary. similar to the way different V-
`series modems fall back to lower
`data rates (28.8 to 14.4 kbits/s. for
`example}. However. when acting in
`this mode. Category II features are
`lost since both modems must be Cat-
`egory II—compliant in order to take
`advantage of the enhanced features.
`
`MI am It scrim
`While specifying a basic set of fea-
`turcs common to any ADSL terminal
`unit (ATU) modem. 'I‘1.413 calls out
`additional functions that enhance
`performance, especially over longer
`and noisier lines. The basic ATU is
`called a Category l modem. while
`the enhanced ATU is called a Cate-
`gory II modem.
`Category II adds two key features
`that can increase data throughput
`significantly trellis coding and echo
`aimless-nu
`cancellation. A third option. called
`The first feature that aids Catcgo~
`power boost—a brute force method
`ry II performance is trellis-coded
`of increasing performance by crank-
`modulation. Trellis coding was first
`3t! I w‘URONIC mutants ht‘tpWeiectmnicpoductnmn OCTOBERI‘HT
`
`introduced in the early 19805 as a
`novel way for modems to overcome
`the etlects of noise found on satellite
`links and telephone lines.
`In trellis coding. bit-error-rate
`(BER) performance is improved by
`mapping groups of data bits to spe-
`cially designed symbol sequences
`that can then be decoded more attu-
`rately in the presence of noise at the
`receiver. By storing the incoming se
`quences of symbols at the receiver.
`clever decoding schemes such as the
`Viterbi algorithm can be employed to
`make better decisions about the actu-
`al transmitted data. Trellis coding
`can boost performance by 4 £13. an
`improvement that can transform a
`marginal BER of 1 error in 1.000 bits
`into a much more palatable BER ofl
`error in 100.000 bits.
`The second performance-boosting
`feature is echo cancellation. a band-
`width—sharing scheme commonly
`used in high-speed dial-up modems.
`To understand the benefit of echo
`canceling, it's necessary to first un-
`derstand how ADSL uses bandwidth.
`ADSL employs full-duplex data
`transmission of up to 5 Mbils/s in
`the downstream direction to the end
`user and up to 640 kbits/s in the up
`stream direction back to the network.
`In Category I. the downstream and
`upstream signals are able to coexist
`on the same line via frequency divi-
`sion multiplexing (FDM) as shown in
`Fig. 2. The dowstream signal is iso
`latcd in the 138 to 1.100-kHz frequen-
`cy band while the upstream signal
`uses the 26 to 134-kHz band. The
`lower 4-th band is reserved for ex-
`isting PUTS voice transmissions.
`To fully maximize the available
`bandwidth. Category ll employs an
`echo cancellation scheme so that the
`downstream and upstream signalsoan
`overlap in frequency (see Fig: 3). The
`chief benefit is that the downstream
`signal now has more bandwidth to
`work with. theoretically boosting data
`throughput by about 10%.
`Since the downstream/ upstream
`signals cannot be separated at the re
`ceiver using normal bandpass filter-
`ing. an echo cancellation circuit
`must be used to subtract out the un-
`wanted transmit signal as well as its

`return echoes (caused by impedance
`mismatches down the line). Echo
`cancellation is clearly a more com-
`plex operation than FDM, but one
`easily implemented with today‘s
`V1.51 technology.
`The extra bandwidth used by the
`downstream signal is in a very desir-
`able location since signal distortion
`caused by the telephone line de-
`creases dramatically at lower fre-
`quencies. in the DMT modulation
`scheme used in ADSL. data is trans-
`mitted over 256 different subcarriers.
`each with its own frequency band
`and bitloading (that is. the number
`of bits transmitted on a subcarrier
`during each symbol time}.
`Typically. the lower-frequency sub-
`carriers can be assigned higher bit-
`loads. since these signals encounter
`less distortion. which means cleaner
`signals and higher data throughpuL
`For example, a subcarrier near 1
`MHz might have a bitload of only 6
`bits/Hz. while a lower-hequency sub
`carrier near 100 kids could have
`twice that amount. Since echo cancel-
`lation switches on extra downstream
`subcarriers in the lower 26 to 138-
`ltHa band. the resulting bitloading
`gains can improve data throughput
`well in excess of the expected 1096.
`
`mm
`Both trellis coding and echo cancel-
`lation are common techniques used to
`squeeze the maximum amount of data
`from a transmission link. while pre-
`
`suring optimized performance. Since
`it is estimated that 80% of telephone
`lines are less than this distance. the
`vast majority of homes can now be
`reached by ADSL service.

`error in 10 million bits). However. in-
