ADC Announces First Single-Pair, Rate-Selectable HDSL Modems Designed for Brazilian Telecom Industry.Business Editors & Technology Writers MINNEAPOLIS--(BUSINESS WIRE)--March 20, 2001 Telebras Compliant WorldDSL Modems to be Displayed at Telexpo ADC (1) See A/D converter. (2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. (Nasdaq:ADCT ADCT Adaptive Discrete Cosine Transform ; www.adc.com), a leading global supplier of fiber optics fiber optics, transmission of digitized messages or information by light pulses along hair-thin glass fibers. Each fiber is surrounded by a cladding having a high index of refractance so that the light is internally reflected and travels the length of the fiber , network equipment, software and integration services for broadband, multiservice networks, today announced five new products added to its WorldDSL line that are designed primarily for the Brazilian market. WorldDSL is a family of HDSL See DSL. HDSL - High bit-rate Digital Subscriber Line access systems designed for the diverse telecommunications needs of global markets. The new WorldDSL additions include the first single-pair rate-selectable HDSL modems in the Brazilian standard Telebras Form Factor. WorldDSL will be on display in the green pavilion, stand B16, March 20-23, 2001, at Telexpo, in Sao Paulo, Brazil. WorldDSL is designed to give telecommunications companies worldwide a simple, economical and more profitable solution for expanding data services and reaching more customers. For Brazilian carriers, WorldDSL marks a new era in HDSL provisioning, providing unprecedented versatility, reach and performance over a single-pair unconditioned unconditioned /un·con·di·tion·ed/ (un?kon-dish´und) not a result of conditioning; unlearned; occurring naturally or spontaneously. copper loop. Telebras Form Factor WorldDSL products include three rate-selectable modems, a network management card and a graphic user interface See GUI. (GUI (Graphical User Interface) A graphics-based user interface that incorporates movable windows, icons and a mouse. The ability to resize application windows and change style and size of fonts are the significant advantages of a GUI vs. a character-based interface. ). "With WorldDSL, ADC provides our Brazilian customers with expert knowledge and experience from turning millions of DSL connections into profits," said Rich Brown, senior product manager for ADC's Wireline Systems Division. "Our Brazilian customers already have the benefit of local manufacturing and support, and now we're providing HDSL modems in the Telebras Form Factor. Our commitment to this market clearly makes ADC a leader in this space." Telebras Compliant WorldDSL Products WorldDSL modems include three Telebras compliant models for addressing the most popular user interfaces in Brazil: Model UTU-731 -- provides G.703/G.704 user interface Model UTU-732 -- provides V.35/V.36/RS-530/X.21 user interface Model UTU-734 -- provides G.703/G.704 and V.35/V.36/RS-530/X.21 user interfaces All three modems perform at any rate from 64 kbps to 2 Mbps over a single twisted pair A thin-diameter wire (22 to 26 gauge) commonly used for telephone and network cabling. The wires are twisted around each other to minimize interference from other twisted pairs in the cable (Alexander Graham Bell invented this and was awarded a patent for it in 1881). . WorldDSL modems support manual configuration, software configuration or a combination of both, giving telcos simple and versatile installation and configuration options. WorldDSL modems also include a built-in Bit Error Rate (BER (1) (Basic Encoding Rules) A set of encoding rules for ASN.1 notation, which is a method for defining data structures. See ASN.1. (2) (Bit Error Rate) The average number of bits transmitted in error. See BERT. 1. ) tester, which eliminates the need for external equipment for testing circuit integrity, as well as other advanced troubleshooting and management features. Other Telebras compliant WorldDSL products include: EMS-831 -- WorldDSL management card EES-897 -- WorldDSL GUI Telebras compliant WorldDSL products are available three to four weeks after receipt of order. WorldDSL is designed to be a growth component into packet switched networks, reducing the end-to-end cost of leased line A private communications channel leased from a common carrier. Most digital lines require four wires (two pairs) for full-duplex transmission. (communications, networking) leased line data services and E1 transmissions. In addition to modems, WorldDSL includes chassis and repeaters for two-pair fixed rate systems and single-pair rate-selectable systems and WorldMUX, an integrated HDSL / Nx64k mux platform. WorldMUX provides extremely high density and versatility, eliminating separate HDSL and multiplexer chassis, costly V.35 cables and intermediate distribution frames. The 19-inch WorldMUX chassis houses up to 12 line cards and four E1 or HDSL network interface cards. About ADC ADC is The Broadband Company(TM).
