DGI Technologies Provides Proven, Cost-Effective Solution to Wireless Carriers Ending Annoying Echo on Cell Phones.RICHARDSON, Texas--(BUSINESS WIRE)--July 26, 1999-- Call Quality for Cellular Customers Significantly Improves DGI DGI Direction Générale des Impôts (French: Department of Revenue) DGI Dirección General Impositiva (Argentina) DGI Danske Gymnastik- & Idrætsforeninger (Denmark) DGI Drummond Group Inc. Technologies Inc., a premier supplier of wireless and cellular switching products, announced today Alltel Communications has successfully implemented and evaluated its DTI-3000 E product on the Motorola EMX EMX - A programming environment for OS/2 by Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>. EMX supports programming in C, C++ and Objective C. It works with gcc, g++, gdb, libg++, .obj linkage, DLL and headers. Version 0.8g. Europe. US. 2500. Alltel tested the DTI-3000 E in their CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. digital cellular environment as well as their inter-switch wire-line trunk connections. DGI's DTI-3000 E is a complete solutions product that resolves the intermittent echo on cellular phone calls and the acoustic background noise of wireless handsets and speakerphones. The successful evaluation of DGI's DTI-3000 E took place at Alltel Communications' Augusta, Ga., location. Alltel plans to use the DTI-3000 E in its Albany, Augusta and Savannah Savannah, city, United States Savannah, city (1990 pop. 137,560), seat of Chatham co., SE Ga., a port of entry on the Savannah River near its mouth; inc. 1789. , Ga., locations as well as its other Motorola CDMA markets. "We chose DGI's product because it's superior to other echo cancellation The elimination of an echo in a two-way voice transmission. Echo is created in the telephone company's central office switch when two-wire lines from the customer are converted to four-wire lines for backbone trunks. products currently available and it is much less expensive," stated Steve Waldrop, director of operations for Alltel Communications. "We are immediately purchasing the DTI-3000 E to implement in our other locations. Alltel will not lose its investment in the technology previously used in Georgia; we will simply re-deploy it." The DTI-3000 E is an integrated trunk interface card that combines trunk interface and echo cancellation functions onto one card. This technology gives cellular and wireless companies the option to upgrade their Motorola(a) EMX 2500 switching systems Switching systems (communications) The assemblies of switching and control devices provided so that any station in a communications system may be connected as desired with any other station. to the latest technology at a substantially reduced cost. The DTI-3000 E product is approximately half the price of competing products. DGI's integrated echo cancellation is priced at $1,000 per span as compared to approximately $2,000 for competition. "All cellular and wireless service providers have problems with intermittent echo, especially during high traffic hours, but most companies are unaware of this problem. The only way the company realizes they have a problem with echo is when cellular customers complain and notify them of it," stated Lyle Coffman, president and COO of DGI. "Our DTI-3000 E is a superior product that cancels problematic echo and saves our customers money at the same time." With DGI's DTI-3000 E, call quality is greatly improved. The DTI-3000 E is available with a variety of configuration options to support various echo cancellation applications including individual channel bypassing to provide a clear channel path for nailed-up data connections. Special features provide additional flexibility in CDMA cellular environments. This universal card is pin compatible to Motorola's DTI-2 and DGI's DTI-2000 Digital Trunk Interface cards and provides trunk interface functions equivalent to those cards. The DTI-3000 E also provides special features for CDMA data applications as well as other data requirements. "With the DTI-3000 E card's complete built-in echo cancellation functionality there is no need for cabling. It's a simple `plug and play' installation," stated Hunter Pinnell, director of global sales for DGI. "This allows our customers to upgrade their current systems, at approximately 50 percent less than the cost of existing equipment, while eliminating many problems. As a result, DGI customers, like Alltel, are in a much better position to increase their customer base and succeed in their respective competitive wireless markets." The DTI-3000 E card offers complete forward and backward compatibility See backward compatible. (jargon) backward compatibility - Able to share data or commands with older versions of itself, or sometimes other older systems, particularly systems it intends to supplant. for use in Motorola standard DTF (Digital Tape Format) A high-performance magnetic tape technology from Sony that was based on the helical scan transport and cartridge shell of Sony's highly successful 1/2" Digital Betacam. shelves and frames, as well as all DGI shelves and frames. This compatibility, in tandem Adv. 1. in tandem - one behind the other; "ride tandem on a bicycle built for two"; "riding horses down the path in tandem" tandem with the additional features, will allow the DTI-3000 E interface card to prolong the life of customers' existing equipment. The DTI-3000 E significantly lowers operating costs operating costs npl → gastos mpl operacionales and expenses by reducing power consumption and heat dissipation. Additionally, valuable floor space required by stand-alone echo cancellers is not needed, thus adding to customers' savings. The DTI-3000 E card provides two standard T1 interfaces, AMI and B7S line codes, as well as Superframe (SF) capability, which is compatible with existing equipment. It additionally provides B8ZS (Binary 8 Zeros Substitution) An encoding method in T1 and E1 transmission that substitutes a special bit pattern for 8 consecutive zeros in order to maintain ones density. See ones density. line code and the ability to select 56 kb/s or 64 kb/s clear channel modes and Extended Superframe (ESF (1) (Extended SuperFrame) An enhanced T1 format that allows a line to be monitored during normal operation. It uses 24 frames grouped together (instead of the 12-frame D4 superframe) and provides room for CRC bits and other diagnostic commands. ) capability. The DTI-3000 E is a direct replacement and enhancement for Motorola's DTI-2 and DGI's DTI-2000 cards.
