DORIS

Since 1992, a group of enthusiasts has been involved in the use of computer technology in scientific research in physics, production management, and communication within a small enterprise. The accumulated experience and practical interest shifted the focus to implementation of telecommunication technologies. A separate specialized enterprise - Closed Joint Stock Company DORIS - was created on the basis of the existing team.

The Company's task was to create the Donbas Regional Information System. Registered in January 1995, the company began actively providing data transmission and electronic document management services. Taking into consideration the work experience and available resources, the enterprise in the framework of joint activity with JV INFOCOM (Kiev) became a regional operator of the National network of packet-switched data transfer UKRPAK in Donetsk and Lugansk regions. Using X.25 protocol, the first in the region began to provide services of e-mail UKRMAIL (based on X.400 system), TELEX and FAXmail, e-mail SPRINT, INTERNET and other services. The leading banks of Donetsk and Lugansk regions, the most important state organizations and a number of leading commercial structures became the clients of the network. Simultaneously, the UKRPAK network was under construction and development. More than 30 switching centers were organized in the cities of Donetsk and Lugansk regions, Lugansk branch of the enterprise was organized.

In 1996 due to the increasing number of clients wishing to receive INTERNET services the independent node was organized and the separate service provision by TCP/IP and X.25 protocols was started.
