Level One Announces Industry's First Multi-Purpose DSL Framer for Digital Pairgain and Internet Access/SOHO Applications.SACRAMENTO, Calif.--(BUSINESS WIRE)--Oct. 26, 1998--Level One Communications, Inc. [Nasdaq:LEVL] today introduced the industry's first multi-purpose DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary framer, the LXP730. When used in combination with Level One's recently introduced Enhanced MDSL MDSL Multi-rate Digital Subscriber Line MDSL Medium-Speed Digital Subscriber Line MDSL Multiple Digital Subscriber Line MDSL maximal dynamic soleus length MDSL Master Deal and Signage List MDSL Maximum Data Segment Length MDSL Moderate Speed Dsl Data Pump (EMDP EMDP Extended Medical Degree Programme (King's College University London; UK) EMDP Engine Model Derivative Program EMDP Exercise Movement and Dance Partnership EMDP Executive & Management Development Program EMDP Electrical Motor-Driven Pump ) chip set, the LXP730 replaces mature ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. digital pairgain systems currently used to provide multiple voice or data connections. This innovative combination of devices provides an excellent low-cost solution for emerging DSL applications such as digital pairgain, Small Office-Home Office (SOHO Soho (sōhō`, sə–), district of Westminster, London, England, known for its continental restaurants. Once a fashionable quarter, it became popular among writers and artists in the 19th cent. )/Internet access and wireless base station access systems. Its user friendly multiple interface and dynamic time-slot interchange allows for simultaneous transport of voice and data signals over a single twisted copper pair, unlike other available solutions. The combination of the LXP730 and the EMDP chip set replaces mature ISDN voice and fax pairgain systems which have traditionally provided two 64 Kbps or four 32 Kbps channel systems around the world. "Level One's LXP730 and MDSL technology is designed to deliver an exciting new level of performance and integration to these applications," said Taufique Ahmed, product marketing manager. "Digital pairgain systems are being widely deployed to provide basic phone services in many emerging economies around the world," Ahmed added. "In more developed countries they are being used to meet additional phone line demand from residential markets. Level One devices offer a very low-cost alternative to meet the price targets for a growing market segment." The LXP730 supports four to eighteen individual 64 Kbps uncompressed channels, eliminating degradation of voice, fax, and modem transmission quality caused by using Adapted Pulse Code Modulation pulse code modulation: see modulation. See PCM. (data) Pulse Code Modulation - (PCM) A method by which an audio signal is represented as digital data. (ADPCM (Adaptive Differential PCM) A widely used variation of PCM that codes the difference between sample points like differential PCM (DPCM), but can also dynamically switch the coding scale to compensate for variations in amplitude and frequency. ) compression techniques. It has eighteen individual single-frame CODEC strobes which provide a flexible architecture to upgrade from four to eighteen channel digital pairgain systems. The combination also supports a hardware mode which eliminates the need for powerful microprocessors. The LXP730 and EMDP chip set is also ideal for voice and data applications directed at SOHO or Internet access markets. Proven, and spectrally compatible, 2B1Q line coding enables the chip combination to provide greater than 1 Mbps data rate and a range exceeding 25 thousand feet at 272 Kbps. In wireless systems such as DECT (Digital Enhanced Cordless Telecommunications) A cordless phone standard mostly used in Europe; however, DECT 6.0 is increasingly used worldwide. The first DECT standards were introduced by ETSI in 1992, and DECT phones have been used as cordless home phones as , multiple base stations need to be aligned in time to strict requirements. The LXP730 offers a guaranteed throughput delay to meet the constant delay requirements of such systems. The LXP730 framer chip combines all the frame, overhead, signaling processing, industry standard PCM (1) See phase change memory.

A time slot interchange circuit allows for easy design of systems that provide dynamic allocation of 64 Kbps time slots to either voice calls or data traffic. The LXP730 also reduces the need for external slip buffers and complicated ASICs while providing benefits of lower chip count at reduced cost, reduced design effort, and a faster time-to-market. Packaging The component is packaged in a 64-pin LQFP See QFP. package. Pricing and Availability The LXP730 is now available in volume production and is priced at $12.00 in 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.
