The ABC's of ADSL
Annex
Whenever you pick up any trade rag these days there is an endless supply of bolder and bolder ADSL product performance claims ranging from data rate speed upgrades to flawless 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 evidence. 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 industry 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 Diamondback 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 offered 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 Modem OEM market for the foreseeable future.

Since ADI is currently the open marketshare leader for ADSL CO chipset deployments and is projected to have a dominant global marketshare in CPE modems with the introduction 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.

ADSL
Integration Zone
CO Solution - AnacondaTM
Analog Devices, the market leader in ADSL silicon solutions, now offers a 6th generation, Central Office (CO), DMT-based ADSL chipset: the AnacondaTM 16-Port. Anaconda is a fully programmable, multimode chipset solution that enables ADSL equipment manufacturers to design high-density line cards for voice switches, DSLAMs, and digital loop carrier equipment. Incorporating higher integration levels and significantly reducing the analog circuitry and components required for the complete design, 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, occupying 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 Category 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 Trellis encoding/decoding, symmetric 512-point FFT/IFFT processing, echo cancellation, 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 external crystal.

Putting the "Pop" back into your Interop
Will the Real Performance Leader Stand Up
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 performance.

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

For the purposes of this article the market regions of interest 100,000 are: 1. Asia/Pacific (China, Japan, Taiwan, S. Korea, India 50,000 and Turkey), 2. Europe (UK, Germany, France, Italy and Spain) 0 and 3. North America (US, Canada and Mexico). From 1996 1996 1997 to 2001 the total worldwide number of fixed-line telephones Source: ITU Telecommunications Indicators/ADI (business + residential) grew from 740 million to over 1.1 billion, 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 60 5.4% respectively. 55

North America and Europe 25 have very stable teledensities; both regions had values of approximately 20 50 in 1996 and 56 in 2001. In these regions, the fixed-line infrastruc15 ture is very well established; any future growth in the number of fixed10 0 lines will be strongly linked with the population growth. Excluding Ja1996 1997 1998 1999 2000 2001 pan (with a 2001 teledensity of 67.6), the Asia/Pacific fixed-line infraAsia/Pacific N. America Europe structure is not well established, but it is rapidly expanding. In 1996 Source: ITU Telecommunications Indicators/ADI Figure - 2 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 Wall 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 Top Worldwide Fixed-line Telecom Operators America and Europe, infrastructure build-out will be tightly aligned 180,000 170,000 with the modest population growth. 160,000

Figure 3 shows the world's top fixed-line telecommunications operators. 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 approximately 50 million fixed-lines. India's DOT is growing rapidly; from 1996 to 2001 the number of main fixed-lines grew from approximately 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.
