OTE SA, the Hellenic Telecommunications Organization, is the major public network operator of Greece and aims to actually promote all services made available through this technology and more peculiarly that of telemedicine. Through its modernization plan in progress, OTE aims at providing wide/range, high/quality competitive services on the basis of customer oriented policies. Its activities cover, besides basic telephony (5,9 million lines), data communications, leased lines, maritime communications and value-added services. The public health service has a lot to profit from efficient use of telecommunications. The greatest challenge the health service is faced with, is the growing gap between the expectations of the population, and the resources that society can set-aside for health purposes. Increasing the level of efficiency and co-operation is therefore the best probable response to the challenge. Telecommunications may contribute to a more effective utilization of resources, tying together those that could be in benefit of the health sectors in the process of implementing a large number of telemedical services.
