DIGIBOARD PRODUCT ENABLES CONNECTION BETWEEN ISDN ISLANDS

 DIGIBOARD PRODUCT ENABLES CONNECTION BETWEEN ISDN ISLANDS
 Minneapolis, Minn., October 15 /PRNewswire/ -- DigiBoard, a division of Digi International (NASDAQ: DGII) today announced that its IMAC ISDN product recently enabled connections between ISDN islands, significantly reducing the cost and increasing the performance for connecting geographically dispersed local area networks (LANs).
 The deployment of ISDN services has been delayed by the lack of interconnection between central office telephone switches that provide ISDN.
 The IMAC connections, made over Basic Rate ISDN lines, will allow the Regional Bell Operating Companies (RBOCs) to connect ISDN islands now, lowering the cost of ISDN deployment and improving service.
 The DigiBoard IMAC LAN extension product connected ISDN service areas between Minneapolis and Cincinnati in an installation developed for Eden Prairie-based SPAR Marketing by NTX, a Minneapolis-based systems integration firm.
 "Our need was to replace a minicomputer with LANs, cut operations costs, and provide a transparent connection between the LANs at both our Minnesota and Ohio offices so that users could access servers at either site," said Boon Tan, MIS director at SPAR. "We were very impressed with the IMAC. We are connected transparently at 12 times the speed and at 75 percent of the cost of analog phone lines."
 NTX was called in to provide the solution. "The solution was obviously a digital connection between the cities, but we needed a creative approach to stay with SPAR's cost goals," said Ed Groess, president of NTX. "Since both of the sites are within ISDN service areas, we used the IMAC's ability to provide high- speed access at minimal cost."
 "Our DigiBoard IMAC overcomes the interconnection barrier by providing high-speed links between LANs over dial-up digital voice lines," said Ham Mathews, general manager of DigiBoard's telecommunications group. "We allow the RBOCs to overcome one of the major barriers to widespread acceptance of ISDN -- a lack of affordable, high-speed connections between areas where ISDN is available."
 "There is a need to make ISDN real, and the DigiBoard IMAC product is a step in the right direction," said Ken Kretchmar, industry consultant at Action Consulting. It picks up where digital data services left off and provides a transparent connection for LANs with specially engineered facilities. Both the market for Basic Rate ISDN and the burgeoning LAN interconnect market will benefit now that people can cost- effectively connect over long distances at speeds closer to those of the LAN."
 Next month, the Transcontinental ISDN Project (TRIP '92) will show connections among 20 switches that support full Signalling System 7 protocols. DigiBoard's IMAC provides connections between virtually all ISDN switches in the U.S. today. The connections are made using existing digital long distance lines.
 The $2,195 DigiBoard IMAC is a tightly integrated ISDN terminal adapter and Ethernet LAN bridge that provides a transparent connection between Ethernet and Basic Rate ISDN. IMAC provides on-demand remote LAN connections via dial-up ISDN phone lines at 56-, 64-, 112- or 128-Kbps throughput. It works with any network operating system, any PC or host computer, and any CCITT ISDN circuit-switched Basic Rate line. Because transparent access to LANs is obtained without the need for dialing commands, IMAC works with any application software that runs on an Ethernet LAN.
 DigiBoard, a division of Digi International, manufactures a suite of connectivity solutions for multiuser systems, and local and wide area networks that support ISA, EISA, and MCA platforms. Rated by industry surveys as having the highest brand recognition of any multiport board supplier worldwide and as providing the finest technical support, DigiBoard products are available worldwide from 65 distributors.
