ADTRAN announces industry's first compressing DDS DSU CSU for use with Frame Relay Circuits.LAS VEGAS--(BUSINESS WIRE)--April 2, 1996--ADTRAN, 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 : ADTN ADTN Administrative Data Transmission Network ADTN Administrative Data Telecommunications Network ) announced today the DSU 1. (communications) DSU - Data Service Unit. 2. DSU - Disk Subsystem Unit (Artecon). 3. (humour) DSU - Dwarf Storage Unit. III ARc, the industry's first DDS (1) (Digital Data Storage) See DAT. (2) (Data Dictionary System) See QuickBuild and OpenDDS. (3) (Dataphone Digital S DSU/CSU (Digital (or Data) Service Unit/Channel Service Unit) A pair of communications devices that connect an inhouse line to an external digital circuit (T1, DDS, etc.). with synchronous data compression designed to optimize throughput over 56 kbps Frame Relay Circuits. The announcement was made at the Networld+Interop Trade Show in Las Vegas. The DSU III ARc is based on the recently announced TIA/EIA 655 specification for compression of bit-formatted synchronous data over point-to-point digital circuits. By incorporating the Frame Relay Forum's Implementation Agreement FRF FRF The ISO 4217 currency code for the French Franc. .9, the DSU III ARc supports compression over multiple permanent virtual circuits. Each unit is capable of supporting compression on up to three PVCs, with an unlimited number of transparent PVCs supported. The DSU III ARc is also compatible with non-compression DSUs for use in existing networks. This feature allows compressing DSUs to be installed on circuits that require increased throughput while maintaining overall network interoperability. According to Gary Culp, design engineer at ADTRAN, the DSU III ARc automatically selects the DLCIs to compress based on the LMI, Annex A of Annex D status messages. This feature allows the units to be installed in new or existing Frame Relay Networks with minimal additional setup or configuration. A manual mode of configuration is also available to allow users to select which PVCs to compress. In addition to the DSU III ARc, ADTRAN also announced Frame Relay support for the DSU III DBUc, the industry's first DDS DSU/CSU to incorporate synchronous data compression as well as ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. , V.32 or Switched 56 dial backup capability. The DSU III ARc is available in standalone configuration, with full numeric keypad and LCD display. List price is $1,125. List prices for the DSU III DBUc units start at $1,495. ADTRAN was established in 1985 to design, develop and manufacture advanced transmission products for high-speed digital communications. In addition to its DDS products, ADTRAN is a primary provider of HDSL See DSL. HDSL - High bit-rate Digital Subscriber Line and ISDN digital loop products to REgional Bell Operating Companies and many well known OEMs. The broad selection of customer premises products offered by ADTRAN includes a complete line of DSU/CSUs, a variety of ISDN extension and network terminating products and flexible T1 multiplexers.
