Annex
The ABC’s of ADSL
Since ADI is currently the open marketshare leader for ADSL
CO chipset deployments and is projected to have a domi-
nant global marketshare in CPE modems with the introduc-
tion of Eagle, it only stands to reason that seamless
interoperability will finally be obtainable for most domestic
and international Telco providers.
Having superior CO and CPE ADSL solutions for Annex A,
B, and C is the rock solid foundation that helps solidify ADI’s
leadership role in the global ADSL marketplace.

Whenever you pick up any trade rag these days there is an
endless supply of bolder and bolder ADSL product perfor-
mance claims ranging from data rate speed upgrades to flaw-
less interoperability, stopping just shy of having the solution
for world hunger. But we all know that most of these claims
are unfounded and certainly not supported by any hard evi-
dence. Despite all of these exaggerated claims, certain facts
cannot be disputed, one of which is the current Global ADSL
deployment marketshare distributions. Within the ADSL in-
dustry it is perceived that Alcatel is the marketshare leader,
when in reality ADI has a dominant marketshare position in
both SEA (80% - including Korea and Taiwan) and Europe
(60%) with both its Annex A and B CO chipset solutions, with
plans to become a major player in Japan (Annex C) to the
tune of 50+% with the introduction of its Anaconda and Dia-
mondback products (up to 12 Mb/s).
On the heels of these significant CO ADSL deployments,
ADI introduced the EagleTM 2-chip CPE solution which is of-
fered in UTOPIA, USB, and PCI interfaces. With Eagle’s
unsurpassed level of integration and enhanced performance
it is anticipated to be the dominant chipset for the CPE Mo-
dem OEM market for the foreseeable future.

CO Solution - AnacondaTM
Analog Devices, the market leader in ADSL silicon solutions, now offers a 6th gen-
eration, Central Office (CO), DMT-based ADSL chipset: the Anaconda TM 16-Port. Ana-
conda is a fully programmable, multimode chipset solution that enables ADSL equip-
ment manufacturers to design high-density line cards for voice switches, DSLAMs,
and digital loop carrier equipment. Incorporating higher integration levels and signifi-
cantly reducing the analog circuitry and components required for the complete de-
sign, Anaconda reduces overall system operating and manufacturing costs while
dramatically improving ease of manufacture. Setting new standards for CO chipset
density, Anaconda allows for the complete solution, from UTOPIA bus to line, occu-
pying a mere 1.1 inches/port and consuming only 1.1 watts/port for full-rate ADSL.
CPE Solution - EagleTM
The Eagle CPE is a highly integrated Customer Premise Equipment chipset that
performs all physical layer functions needed to implement standards-compliant Cat-
egory 1 and Category 2 Asymmetric Digital Subscriber Line (ADSL) modems. The
analog IC integrates several passive and active components, a line driver an AFE to
reduce the number of components. The digital IC integrates a DSP, DMT coprocessor ,
framer, and interleave RAM. The programmable DMT engine performs QAM or Trel-
lis encoding/decoding, symmetric 512-point FFT/IFFT processing, echo cancella-
tion, time/frequency-domain equalization, and transmit/filtering. The FFT/IFFT bin
assignments are completely programmable to support ADSL over ISDN (Annex B
and C). The framer provides ATM TC sublayer processing, standard and reduced
overhead ADSL framing, and FEC with interleaving. Dual latency and multi-frame
code words are supported. Software-based modem control and configuration allows
for considerable flexibility in configuration and management. The chip supports very
low-power standby and D3 cold ADSL remote wake-up through an on-board circuit to
detect central office (CO) transmitted wake-up tones. On-chip digital timing recovery
eliminates the need for a VCXO and allows Eagle to run from a single 12 MHz exter-
nal crystal.

The dispute over ADSL interoperability has raged on ever since the mass deployment of ADSL technology
became a reality. Since Analog Devices is a major player in that space it would make sense for ADI to
insure that their respective products were compatible with other leading providers to minimize connection
errors. After a comprehensive and exhaustive series of independent tests, the following results were
presented as it related to Analog Devices and another major competitors (Comp A) interoperability perfor-
mance. Upstream

The most recent downturn in the ADSL market
further illustrates just how volatile and
unpredictable this industry truly is. With
variables such as performance, interoperability ,
delivery , tech support, install base, etc. it would
be best to partner with a company that has the
proven technical and financial resources to
insure continued support and leadership
through the good and bad times. As depicted
by the “Marketshare” data, it becomes quite
evident that ADI has what it takes to lead and
survive the tumultuous and unforgiving
landscape of the xDSL marketplace. With a
dominant worldwide CO marketshare and
industry leading CPE products, ADI plans on
continuing to provide the best in products and
services for our existing and new customers.

Traversing the “Telco” Topography
This article is the first in a series Telecommunications-related
articles. Future articles will: I) explore the various telecom-
munications service providers, by region, in detail, II) analyze
worldwide ADSL/G.SHDSL/VDSL deployments, III) explain the
various broadband voice technologies such as, VoIP, VoATM
and CVoDSL, IV) review PSTN, ATM and IP networks and V)
describe the various termination equipment such as, IADs,
Gateways, DSLAMs, DLCs and mini-DSLAMs (for MTU/MDU
applications).
For the purposes of this article the market regions of interest
are: 1. Asia/Pacific (China, Japan, Taiwan, S. Korea, India
and Turkey), 2. Europe (UK, Germany , France, Italy and Spain)
and 3. North America (US, Canada and Mexico). From 1996
to 2001 the total worldwide number of fixed-line telephones
(business + residential) grew from 740 million to over 1.1 bil-
lion, this growth corresponds to a CAGR of 8.5%. The growth
however was not uniform over the various market regions. As Figure 1
illustrates, the number of fixed-lines in the Asia/Pacific region grew at a
CAGR of 42.3%, while North America and Europe grew at 10.3% and
5.4% respectively.
Teledensity (# of main phone lines / 100 people) helps explain the
reason behind the growth in the Asia/Pacific region. Figure 2 shows
the teledensities for the 3 market regions. North America and Europe
have very stable teledensities; both regions had values of approximately
50 in 1996 and 56 in 2001. In these regions, the fixed-line infrastruc-
ture is very well established; any future growth in the number of fixed-
lines will be strongly linked with the population growth. Excluding Ja-
pan (with a 2001 teledensity of 67.6), the Asia/Pacific fixed-line infra-
structure is not well established, but it is rapidly expanding. In 1996
China’s and India’s teledensities were 4.4 and 1.5, respectively. By
2001, China’s teledensity increased to 14.1 while India’s remained low
at 3.8. China’s 3-fold increase is due to its aggressive infrastructure build-out. According to a recent W all Street Journal article, by the year
2005, China’s Ministry of Information Industry (MII) is planning to have between 220 to 260 million fixed-lines, representing teledensities of
16.9 and 20.0, respectively. The cost of this build-out will exceed $150 billion.
Referring back to Figure 1, the growth driver in fixed-lines for the
Asia/Pacific region is aggressive infrastructure build-out. For North
America and Europe, infrastructure build-out will be tightly aligned
with the modest population growth.
Figure 3 shows the world’s top fixed-line telecommunications op-
erators. In 2001, with nearly 180 million main fixed-lines, China
Telecom occupies the number 1 position. NTT is the largest in
Japan and ranks second in the world with approximately 73 million
fixed-lines. The top two telcos in the US are Verizon (~72M) and
SBC (~65M). Deutsche Telecom is Europe’s largest telco with ap-
proximately 50 million fixed-lines. India’s DOT is growing rapidly;
from 1996 to 2001 the number of main fixed-lines grew from ap-
proximately 11 million to over 26 million. From an ADSL rollout
perspective it is interesting to note Korea Telecom’s success. KT
is the world’s ADSL leader even though it is only the world’s 10th
largest fixed-line telco. Future articles will discuss each region’s
telecom operators and ADSL rollout projections.

The core of the network has been moving from circuit-switching to the more efficient
packet switching over the last few years. Local Exchange Carriers have been ag-
gressively rolling out broadband services for data. We are now starting to see a
revolution that will take advantage of voice packetization in the local loop (last mile)
infrastructure. Applications like Voice over ATM (Vo ATM) and Voice over IP (VoIP)
enable carriers to bundle voice and data services over the same local loop providing
multiple channels of voice and high-speed data access. The AD6689 Voice over
Packet processors along with the integrated software will provide the functionality
needed for Layer 2 to Layer 7 applications.
The AD6689 solution provides the functionality needed for emerging broadband ap-
plications including scaleable, fast path QoS engines, policy-driven bandwidth man-
agement, and scaleable pipelined flows of security under the control of policy man-
agement including stateful firewalls. The AD6689 solution helps the system vendor
go to market faster by providing a highly integrated System-On-A-Chip (SoC). The
SoC comes with a reference board and complete software. A powerful Application
Programming Interface (API)
and plenty of processing power
are available for the system
vendor to provide differentiated
value-addition to the system.
AD6689 optimizes the split of
functionality between hardware
and software – this ensures
high performance while provid-
ing a flexible platform suited to
a wide variety of applications –
IP, ATM and Frame-Relay.
