IDT Introduces Family of High-Density T1/J1/E1 Line Interface Units Optimized for Optical Transport Applications.SAN JOSE, Calif. -- New Family of 28-, 21- and 16-Channel Devices Enhance System Functionality While Slashing Board Space and Power IDT IDT Integrated Device Technology, Inc. (Santa Clara, CA, USA) IDT I Don't Think IDT Identity Theft IDT Interrupt Descriptor Table IDT Integrated DNA Technologies IDT Inactive Duty Training IDT Instructional Design & Technology (TM) (Integrated Device Technology IDT (NASDAQ: IDTI) was founded in 1980 as a semiconductor vendor. Employing approximately 2500 people worldwide, headquartered in San Jose, California and operating a fab in Hillsboro, Oregon, the company both designs and fabricates semiconductor components. , Inc.)(NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :IDTI IDTI Integrated Device Technology Inc ), a leading communications IC company, today bolstered its leadership in the T1/E1/J1 market with the introduction of a new family of high-density line interface units (LIUs). The family, which includes 28-, 21- and 16-channel options in ultra-small packages, provides an optimized set of solutions for tributary aggregation in applications such as multi-service provisioning platforms (MSPPs), optical multiplexers, edge routers and wireless transport systems. These products are the latest addition to the company's strong portfolio of telecom solutions, which includes industry-leading T1/E1/J1 transceivers, LIU LIU Linköpings Universitet (Sweden) LIU Long Island University (New York) LIU Line Interface Unit LIU Lightguide Interconnection Unit (AT&T) LIU Laugh It Up and framer products, Inverse Multiplexer over ATM (IMA (Interactive Multimedia Association, Annapolis, MD) An earlier trade association founded in 1988 originally as the Interactive Video Industry Association. It provided an open process for adopting existing technologies and was involved in subjects such as networked services, scripting ) devices, Stratum compliant WAN PLLs and time slot interchange (TSI TSI Total Solar Irradiance (sum solar light in energy per unit of time) TSI Trading Standards Institute (UK) TSI Transportation Safety Institute (US DOT) ) switches. "IDT LIU solutions have achieved prodigious success with top vendors in the metro optical transport market, and today we're giving our customers a powerful new set of products to enhance the next generation of these systems. Multi-service provisioning platforms are a great example of this," said Sean Fan, director of marketing for the telecommunications products division at IDT. "By integrating up to 28 ports with software impedance matching, termination components and frequency synthesizers, the IDT high-density LIUs reduce power, board space and cost -- three crucial considerations in these compact systems. Moreover, key features such as per-channel control of T1, E1 or J1 formatting and in-service testing translate into system-level functionality that ultimately benefits our customers' customers." Innovative Cost and Board Space Benefits The new family includes 28-, 21- and 16-port devices and offers nearly four times the density of other LIU solutions on a single chip, saving at least 20 percent in board space. The high-density LIU devices also offer very flexible line and system interface configuration options to address a wide range of applications. An industry-standard system interface ensures support for both commercial and custom framing and mapping circuits with standard TDM (Time Division Multiplexing) A technology that transmits multiple signals simultaneously over a single transmission path. Each lower-speed signal is time sliced into one high-speed transmission. interfaces. Each channel of the high-density LIU can be selected to operate independently in T1, J1 or E1 (75/120 ohm) mode. Fully integrated and software-programmable internal impedance circuits enable designers to save external components and address multiple markets with a single bill of materials The list of components that make up a system. For example, a bill of materials for a house would include the cement block, lumber, shingles, doors, windows, plumbing, electric, heating and so on. . The new IDT devices also offer various line termination configuration options, including the industry's first true single-ended termination for E1 applications on the primary and secondary side of the transformer. Up to 63 valuable backplane traces can be saved when routing lines from the I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output panel to the LIU. IDT has also pioneered an innovative transformer-less operation and single-ended termination mode for differential T1/J1 and E1 lines to provide additional space and cost savings in intra-building applications. The new LIU devices deliver an optimized architecture to support 1+1 and 1:1 hitless protection switching without external relays, thereby enabling redundancy in high-availability systems. Other features include the provision of two output clocks derived from any of the recovered line clocks. An integrated clock synthesizer is available as an option to scale these clocks to a wide range of frequencies from 8 kHz to 32.768 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. . A cascading feature is also provided to select a single reference clock from multiple devices without the need for any external logic. The IDT high-density LIU devices ensure standards compliance by meeting or exceeding popular networking specifications by ANSI (American National Standards Institute, New York, www.ansi.org) A membership organization founded in 1918 that coordinates the development of U.S. voluntary national standards in both the private and public sectors. It is the U.S. member body to ISO and IEC. , ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. , ETSI (European Telecommunications Standards Institute, Sophia Antipolis technical park, Nice, France, www.etsi.org) A non-profit membership organization founded in 1988, dedicated to standardizing information and communication technologies (ICT) throughout Europe. and AT&T. Dedicated monitor channels that meet the ITU G.772 requirements for in-service monitoring are available on every device option (i.e. 28(+1), 21(+1), 16(+1) channel). Pricing and Availability The IDT high-density LIU devices are currently sampling with production quantities available in July. Pricing for the new high-density LIU family ranges from $28.00 to $45.00 each in high-volume OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and quantities. IDT Green and RoHS compliant versions will be available in Q4CY05. Additional product information can be found on the IDT Web site at http://www.idt.com/?id=28.
