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 adis leadership role in the global adsl marketplace. 123456789 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 12345678 9 123456789 123456789 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 123456789 123456789 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 1 2345678 9 123456789 sea europe us japan 1234567890 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1 23456789 0 1234567890 0 100 85% 60% 30% *55% annex a annex a & b annex a annex c 50 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 eagle tm 2-chip cpe solution which is of- fered in utopia, usb, and pci interfaces. with eagles 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. over 14 million adsl chipsets delivered to date -1- analog devices global adsl deployments marketshare - co chipsets marketshare (%) * - estimated projection
co solution - anaconda tm 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 - eagle tm 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. eagle-usb reference design board shown anaconda reference design line card shown adsl 1234567 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1234567 1234567 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1234567 1234567 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1 23456 7 1234567 123456 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 1 2345 6 123456 16-port co solution usb cpe solution total component count (%) competitor average 50% reduction total bom reduction comparison competitor average 50% reduction integration zone -2- anaconda eagle
putting the ?pop? back into your interop 18,000 9,000 0 0.5 1.0 data speed rates (mb/s) 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 adi/adi compa/compa compa/adi will the real performance leader stand up distance (ft.) from co data speed rates (mb/s) downstream distance (ft.) from co no matter how you slice it, adi is on top 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. co adsl ic port shipments merchant marketshare (%) 2001 10.3m ports 2002 13.8m ports 2003 14m ports analog devices, inc. texas instruments globespan centillium 18.1 28.3 16.9 36. 7 42.9 21.2 23. 4 12.5 7.2 17.9 52.6 22.3 -3- 18,000 9,000 0 8.0 4.0 12.0 15,000
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 chinas and indias teledensities were 4.4 and 1.5, respectively. by 2001, chinas teledensity increased to 14.1 while indias remained low at 3.8. chinas 3-fold increase is due to its aggressive infrastructure build-out. according to a recent wall street journal article, by the year 2005, chinas ministry of information industry (mii) is planning to have between 220 to 260 million fixed-lines, representing t eledensities 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 worlds 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 europes largest telco with ap- proximately 50 million fixed-lines. indias 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 telecoms success. kt is the worlds adsl leader even though it is only the worlds 10 th largest fixed-line telco. future articles will discuss each regions telecom operators and adsl rollout projections. the texts extracted from the itu material have been reproduced with the prior authorization of the union as copyright holder. -4- 1996 1997 1998 1999 2000 2001 400,000 350,000 300,000 250,000 200,000 150,000 100,000 50,000 0 lines (000s) number of fixed-line telephones by region asia/pacific n. america europe source: itu telecommunications indicators/adi 1996 1997 1998 1999 2000 2001 mainlines per 100 people teledensity asia/pacific n. america europe source: itu telecommunications indicators/adi china telecom verizon ntt sbc deutsche telecom france telecom british telecom telecom italia bellsouth korea telecom dot turk telecom telefonica chungwa telecom bell canada telmex qwest 180,000 170,000 160,000 150,000 140,000 130,000 120,000 110,000 100,000 90,000 80,000 70,000 60,000 50,000 40,000 30,000 20,000 10,000 0 top worldwide fixed-line telecom operators 1996 1997 1998 1999 2000 2001 lines (000s) source: itu telecommunications indicators/adi figure - 3 figure - 1 figure - 2 0 60 55 50 45 40 35 30 25 20 15 10
