Spon- sored by the International Radiobroadcasting and Television Organization (OIRT),* Intervision connects the television systems of the European Satellites and the USSR and provides connections with Eurovision, the Western European television network. Network operations began in 1960, at which time the television systems of East Germany, Czechoslovakia, Hungary, and Poland were linked through the use of temporary microwave radio relay facilities. Since that year, coverage of the network has grown steadily, and temporary connections subsequently have been re_-_:.:. placed by fixed installations. In 1962 the USSR joined the network, and Bloc-wide coverage was achieved early in 1963 when the television systems of Bulgaria and Rumania were linked to the network. The main network of arterial intra-Bloc and domestic com- munications lines serves as the transmission base for the Intervision network. These facilities (shown on the map, Figure lam) depict main Intervision lines and border connecting points and provide some insight into the coverage of the television systems of individual Satellite countries. Because of the multipurpose nature of these new arterial lines, it is not unreasonable to assume that the publicity given to the establishment of the Intervision network, at least in its formative years, served as a convenient facade to shield the development of a strategic telecommunications resource base. In any case, the Bloc- wide functioning of the network demonstrates that still another major goal of OSS is nearing completion. C. Major Problem Areas As might be expected, problem areas exist that may prevent the European Satellites from meeting all plans by 1965. Foremost among these, and indeed the most pressing immediate problem, is the shortage of carrier-frequency multiplex equipment. Such shortages have existed since the inception of the program, and there is no evidence to suggest that significant progress has been made during the past 5 years toward the elimination of these shortages. The immediacy of the problem stems from the buildup of intra-Bloc and national arterial routes that has carried with it a massive requirement for associated multiplex, equipment with capacities ranging from 12, 24, and 60 telephone channels up through and including equipment capable of handling 1,920.telephone channels. An adequate supply of such equipment is absolutely necessary for the full or even partial func- tioning of newly constructed lines as well as those scheduled for completion by the end of 1965- * OIRT is an agency organized and dominated by the Soviet Bloc that effects cooperation among Bloc countries as well as some non-Bloc countries in the field of radiobroadcasting and television. ** Following p. 4, above. - 7 - S-E-C-R-E-T Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 Although 12-channel and 24-channel equipment appears to be manufactured in sufficient quantities to meet new and recurring needs, series production of equipment with a capacity of 60 or more channels lags seriously. At present, East Germany, Hungary, and Czechoslovakia are the only European Satellites producing 60-channel equipment, and their output falls far short of minimal needs. Furthermore, production of higher capacity equipment is nonexistent even though research for the development of such equipment has been underway for a number of years. Because of these failings, lines completed during the last 3 or 4 years are not being equipped to operate at levels approaching designed capacities. The magnitude of this problem is indicated by the fact that no completed Vesna-type microwave radio relay line in the European Satellites is known to be passing telephone traffic. Similarly the passage of telephone traffic over the nearly completed 4-tube coaxial cable route connecting Poland, Czechoslovakia, and East Germany is wholly contingent on the ability of the USSR to supply as;; sociated carrier equipment. In spite of the fact that a commitment has been made in this regard, it is still not certain that it will be met as scheduled. The lag in the availability of carrier equipment is related to continued difficulties in mastering techniques for the series produc- tion of uniformly high-quality components, such as crystal filters and metal contacts. Even when 60-channel equipment has been delivered and installed, its performance has often failed to meet minimum standards. An outstanding example of this is the V-60 and V-60S equipment pro- duced by East Germany. D. Emergence of a Bloc-Wide Strategic Telecommunications Complex The end of 1965 will see the emergence of a Bloc-wide telecommuni- cations complex that can promote more effectively the economic, military, and political interests of the area. Although the arterial routes of intra-Bloc and domestic communications lines in the European Satellites will not be completed fully by the end of 1965, they will nevertheless begin to function as an integrated network that is capable of handling a broad array of conventional and specialized service. This vastly improved level of communications will be achieved in spite of the dif- ficulties that are being experienced in equippipg the new transmission systems. This improved capability will have a significant impact on the posture of military communications. The new complex of arterial trans- mission systems will contribute greatly toward closing the gap existing between the modern offensive and defensive weapons systems deployed throughout the European Satellites and the communications facilities and services needed for their support. The increased reliability of these facilities as well as their extensive geographic coverage (which S-E-C-R-E-T Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 includes all major areas of strategic military importance) assures their use as the primary media for domestic and intra-Bloc military traffic. Usage will encompass a wide field of strategic and tactical military applications ranging from supporting long-distance command- control structures to meeting national and Bloc air defense require- ments. Gains made in automating domestic and intra-Bloc telephone and telegraph networks also will serve to enhance the strategic military significance of the emerging Bloc telecommunications system. II. Plans and Prospects, 1966-75 In the early part of 1966-75 a push will be made to complete all main intra-Bloc and domestic communications lines and to equip these lines to their designed capacities. Some technological advances will be made by the introduction of new transmission media, but the main emphasis throughout the period will be on the expansion and automation of exchange and subscriber facilities, both domestic and intra-Bloc. A. Technological Developments 1. Cable and Microwave Radio Relay Facilities With the exception of the introduction of some 1.5 mega- cycle small-diameter coaxial cable and some more advanced microwave radio relay systems operating in the 6-gigacycle range,* there will be little over-all change in the basic composition of transmission systems. The use of small-diameter coaxial cable will be confined primarily to Poland and Czechoslovakia as feeder lines off main coaxial cable and microwave radio relay routes. For the most part, 6-gigacycle microwave radio relay equipment will be used to upgrade existing arterial microwave radio relay routes to meet additional traffic needs. This new microwave equipment, which is currently under development at the Budapest Telecommunications Research Insti- tute, supposedly is capable of handling television traffic as well as 10,000 telephone channels. Reportedly it will use carrier equipment with a capacity of 1,920 telephone channels per radiofrequency truck. There are no known operational tropospheric scatter facili- ties in the European Satellites. Moreover, there appears to be no operational requirement for this medium for mainline communications purposes even though East Germany is conducting feasibility studies over five experimental circuits. These circuits connect the main terminal at Kolberg (near East Berlin) with Dresden, Fichtelberg, and Inselberg (all in East Germany) and with Poznan (in Poland) and Prague (in Czechoslovakia). * One gigacycle equals 1,000 megacycles. - 9 - S-E-C-R-E-T Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 The applicability of tropospheric scatter to the communica- tions requirements of the USSR is more apparent. Field tests of ex- perimental tropospheric scatter systems in the USSR date back to 1957. At that time a circuit was set up between Leningrad and Petrozavodsk, a distance of 192 miles, using frequencies of 310 megacycles and 1,000 megacycles. The existence of a second experimental circuit between Frunze and Przheval'sk, a distance of about 180 miles, was announced in April 1958. More recently, official statements have alluded to plans for the construction of tropospheric scatter facilities by 1965. Evidence of operational systems, however, has been limited largely to isolated reports of probable tropospheric scatter antennas south of Moscow. In spite of this scarcity of information, it is believed that the USSR has a program for the employment of tropospheric scatter systems in the remote reaches of the Arctic and in Central and Eastern Siberia to support the growing economic and military requirements of these areas for high-capacity and reliable communications facilities. 3. Communications Satellites Within the Soviet Bloc, only the USSR has the economic and technical resources to undertake an independent program for the establishment of a communications satellite system. There is, however, little incentive for the USSR to undertake such a program, as the major economic justification for a communications satellite is its use on high-density transoceanic routes. Although Soviet transoceanic communications requirements are growing through increased economic and political contact with non-Bloc countries, they are nevertheless minimal. Moreover, most of the high-density traffic requirements of the USSR are with contiguous European Satellite countries. Internal Soviet and intra-Bloc facilities that are planned for completion by the end of 1965 will have sufficient capacity and potential for ex- pansion-.to, satisfy these requirements at least through 1975. The major alternative to establishing an independent com- munications satellite system is cooperating with the West in worldwide or regional systems. A joint venture with Western nations would be particularly attractive because it would enable the USSR to apply the scientific, engineering, and manufacturing resources necessary for an independent system to other priority programs and to relate service costs more realistically to service requirements. Although Soviet intentions are unclear, there has been some recent evidence to suggest interest in cooperation with the West. If such cooperation materializes, access to Western communications satellite systems probably would be made available to European Satel- lite countries through Soviet ground terminals.

Electronic Switching Facilities The European Satellites have tied long-run improvements in the quality and quantity of telephone service to the eventual widespread introduction of electronic telephone exchange (EATZ) equipment. The use of such equipment, which has no moving contacts, would increase switch- ing speeds as much as 1,000 times and would reduce greatly the instal- lation, operating, and maintenance costs. Since 1961, East Germany, under the aegis of OSS, has been coordinating a Bloc-wide effort to develop EATZ equipment for operational introduction by 1970 or soon. thereafter. Efforts to date, however, have not resulted in signifi- cant progress because of problems in the mass production of low-cost, reliable semiconductor components with an operating ifespan of 20 to 30 years. Once this bottleneck is overcome, series production of equipment should move ahead. Significant quantities of such equipment, however, probably will not be available for operational use until 1975. B. Completion of a Modern Telecommunications Resource Base In their attempt to complete a modern telecommunications resource base by the end of 1975, the European Satellites will be faced with an expanding requirement for investment funds and equipment. The comple- tion of new transmission systems soon after 1965 will not terminate the need for large capital outlays.* Rather, it will signify the end of one stage in the plan for the development of telecommunications and the beginning of another more intensified stage -- that of expanding tele- phone, telegraph, and data exchange and subscriber facilities so as to exploit the expanded channel capacities of new domestic and intra-Bloc networks. In countries such as Poland and Czechoslovakia, for example, plans for 1960-80 provide for the rapid expansion of all telecommunica- tions services, including a major program for installing 5 million more telephones in each country. Given a minimum estimated investment cost of $200 for each additional telephone subscriber line, capital outlays in each country for telephone facilities alone would approximate $1 bil- lion for the 20-year period. This level of investment, even when con- sidered on an annual basis of $50 million, coupled with investments involved in enlarging other telecommunications services, will consti- tute a heavy demand on the financial and economic resources of these countries for telecommunications. Based on Soviet investment costs, 1 route-mile of operational 4-tube coaxial cable costs about $20,000, and 1 route-mile of operational Vesna-type microwave radio relay line costs about $10,000. (Dollar values are given in current US dollars throughout this publication.) Total investment costs for arterial intra-Bloc coaxial cable and Vesna- type microwave radio relay lines, exclusive of those constructed in the USSR, are estimated to be between $90 million and $100 million. - 11 - S-E-C-R-E-T Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 Even assuming that the investment requirements for programs of this magnitude can be met, it is nevertheless evident that progress made throughout 1966-75 will be contingent on the increased availability of modern telecommunications equipment, especially high-capacity carrier systems and exchange and subscriber facilities. Although cognizant of this requirement, the European Satellites may not be able to cope fully with it, because of competing military demands on existing facilities for manufacturing electronics equipment and deficiencies in production technology. These factors suggest that not all major objectives for moderniz- ing and expanding the telecommunications system of the European Satel- lites will be met by the end of 1975. The strategic importance of intra-Bloc systems insures their completion, but it is unlikely that complementary goals for enlarging domestic systems will be met entirely. Even if the attainment of domestic goals is delayed as much as 5 years, however, the telecommunications systems of the European Satellites,,-in view of the extensiveness of the over-all programs:; will be,improved vastly by 1975. - 12 - S-E-C-R-E-T Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 SECRET Approved For Release 2000/OS CC DP79T01049A002900110001-7 Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 SECRET 50 PROSPECTS AND PROBLEM AREAS FOR THE DEVELOPMENT OF TELECOMMUNICATIONS IN THE EUROPEAN SATELLITES 1959-75 April 196+ GROUP 1 Excluded from automatic nradioand Approved For Release 2000/D I DP79 dow 110001-7 Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 25X1 C The publication is focused on the buildup of the strategic tele- communications resources of the European Satellites* during 1959-75.

To achieve this end, the main development thrust during 1959-65 was keyed to the installation of a compatible mix of high-capacity coaxial cable and microwave radio relay trans- mission systems that would meet both present and projected intra-Bloc and domestic needs for an arterial communications network. At the same time, work also was to begin on the automation of intra-Bloc tele- phone and telegraph exchange facilities, and Bloc-wide television serv- ice was to be inaugurated. Since its inception the program has been marked by steady progress. Although only small segments of the 2,000 miles of 4-tube coaxial cable and 1+,750 miles of high-capacity microwave radio relay lines had been completed by April 1961+, large sections were nearing completion. More- over, an automated intra-Bloc telegraph network was activated by mid- 1962, operations on a Bloc-wide television network began in 1963, and early in 1964 work was nearing completion on a semiautomatic intra- Bloc telephone network. Installation of the new transmission base should be completed by the end of 1965 or soon thereafter. Because of chronic Bloc-wide shortages of associated carrier-frequency multiplex equipment, these new facilities will not operate at their designed capacities, but they will nevertheless function as part of an integrated network capa- ble of handling a wide range of conventional and specialized services. This improved capability also will serve to strengthen the posture of strategic and tactical military communications by closing the gap that exists at present between the modern weapons systems deployed through- out the European Satellites and the communications facilities and services needed for their support and command control. During 1966-75 the initial effort will be on completing all main intra-Bloc and domestic communications lines and equipping them to operate at their designed capacities, but main emphasis will be on the expansion and full automation of intra-Bloc and domestic telephone and telegraph exchange and subscriber facilities.

Even if delays do occur in individual domestic systems, however, the over-all telecommunications system of the European Satel- lites will be vastly improved by the end of 1975- - 2 - S-E-C-R-E-T Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 I. Integrated Development Through 1965 A. Organization for Cooperation Among Socialist Countries in the Fields of Post and Communications (OS-ST- The establishment of OSS* in 1957 set in motion forces that are producing a striking change in the structure and composition of the telecommunications services and facilities of the European Satellites. Since its inception, OSS has had as its major long-range objective the establishment of a modern Bloc-wide telecommunications system that can, meet the burgeoning requirements of official and military users, and to a lesser extent the general public, for automated, high-speed, co-?- ventional and specialized telephone, telegraph, data, and television. services. Toward this objective the European Satellites undertook the following as their initial program for 1957-65: (1) the construction of an integrated arterial network of high-capacity transmission systems, (2) the partial automation of telephone and telegraph exchange facilities, and (3) the inauguration of intra-Bloc network television service. After a somewhat halting start in 1957 and 1958 -- marked by indecision as to the choice of equipment and the routing of intra-Bloc transmission lines as well as by problems in mobilizing indigenous material, manpower, and technological resources -- development of the system began in earnest in 1959. Since that year, steady if not spec- tacular progress has been made. Although far from complete, the work that has begun represents the hard core of a modern Bloc-wide tele- communications system. B. System Development 1. High-Capacity Transmission Systems A prerequisite to the establishment of a modern Bloc-wide telecommunications complex was the construction of an extensive net- work of arterial transmission systems to serve both intra-Bloc and domestic communications needs. Consequently, in the selection of high- capacity transmission media, care was taken to introduce compatible systems that incorporated modern, yet proven, communications tec,_nignes. As shown on the map, Figure 1,** intra-Bloc arterial routes use 4-tube coaxial cable and broadband microwave radio relay facilities that. have a capacity of up to 2,000 telephone channels plus television. Facii:.tie.= used on domestic communications routes consist of 8-pair and 14-pair * Membership in OSS includes the following countries: the USSR, Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland, Rumania, Communist China, Mongolia, North Korea, and North Vietnam. Although not a member, Yugoslavia does have observer status. ** Following p. 4, below. -3- S-E-C-R-E-T Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 Approved For Release 2000/05/15: CIA-RDP79TO1049AO02900110001-7 S-E-C-R-E-T i double-track styroflex multicondiictor cables that can handle up to 960 and 1,680 telephone channels, respectively, and microwave radio relay systems with capacities of from 24 to 120 telephone channels plus television.

On most coaxial cable routes u.~.der construction in Poland and Czechoslovakia, for example, the cable and repeater tanks already are installed, with partial or full operation contingent on the installation of associated multiplex equipment. As for microwave radio relay lines, Vesna-type towers are completed or are nearing completion on nearly all routes under construction in Bulgaria, Hungary, and Rumania, and the installa- tion of transmission equipment is believed to be imminent. Apart from the choice of transmission systems, a determined effort to construct a diversified and reliable telecommunications system is explicit in the configuration of both the domestic and the intra- Bloc networks. The arterial routes of most domestic networks consist of parallel microwave radio relay and hardened cable systems. Duplica- " tion of high-capacity transmission systems also is provided for in the network of intra-Bloc lines. The main axis of this network inter- connects Moscow, Warsaw, Prague, and East Berlin with parallel installa- tions of ~I--tube coaxial cable and Vesna-type microwave radio relay lines. This balanced installation of facilities, including the hardened con- struction of cable terminal and repeater stations and the construction of bypass cable rings around major industrial and strategic areas, im- proves the reliability of communications inasmuch as traffic can flow over alternate media or routes should any part of the network become inoperable. Photographs of microwave radio relay and coaxial cable facilities are shown in Figure lA.-~ 2. Automation of Telephone and Telegraph Systems The introduction of modern high-capacity transmission systems has given added stimulus to the efforts of the European Satel- lites to automate their domestic telephone and telegraph systems. Gains in converting these domestic systems to semiautomatic and fully automatic operations are emphasized by the progress made in establish- ing new automated networks for intra-Bloc telephone and telegraph traffic. a. Telephone The first stage in the construction of an automated long-distance intea-Bloc telephone network is nearing completion. The network, as shown. on the map, Figure 2,~ should be operational by the end of 196+, at which time it will connect each of the capital cities of the European Satellites and the USSR with one another and with the ~ Following p. 6, below.
