The visit by this consultant is primarily for the purpose of studying the possibilities for incorporating the People's Republic of Angola into PANAFTEL (Pan-African Telecommunications Network), which is being established to interconnect the countries of Africa. During his stay, the representative of the International Telecommunications Union has already visited the telecommunications installations of the Luanda area, and in particular the telephone exchanges, the satellite communications station at Funda, and the Center for Vocational Training in Telecommunications and Electronics at Luanda Airport. He was accompanied on these visits by the Director General of Telecommunications, Comrade Humberto Bessa Victor, and also took the opportunity to confer directly with the directors of the Postal and Telecommunications Services, Public Telecommunications Enterprise, and Civil Aeronautics Service, and with top officials of the individual installations visited. Tedros is scheduled to continue his stay in Angola for several more days. [Text] [Luanda JORNAL DE ANGOLA in Portuguese 26 Jul?? p 2] 1U, pyc. ADMINISTRATIVE TELECOMMUNICATIONS CENTER--The present communications service öf the Directorate of Information and Security of Angola is going to come under the direct jurisdiction of the prime minister, and will be known as the Administrative Telecommunications Center (CTA), according to a decree issued by the office of president of the republic just published in the official gazette. According to the aforementioned decree, the organic statutes governing the Administrative Telecommunications Center just established have also been approved. The purpose of the aforesaid center will be to establish and ensure the radio communications considered necessary in support of the executive department of the government, provide for the security of the materials transmitted, and to keep in operating condition the communications equipment and auxilliary components which constitute the Administrative Telecommunications Network (RTA).

SECOND EARTH STATION TO GIVE GLOBAL COMMUNICATION Kampala VOICE OF UGANDA in English 25 Jul 77 p 5 ^/Article by Zulf Khalfan/ /Text/ ANOTHER earth satellite station will mushroom on Uganda's landscape in less than two years time. Though it will follow the alread y completed and about to be com-: missioned Arua earth station, it was in fact the originally planned earth station for the country. This one will be a much bigger project than the Arua one, both in costs, size, and capacity. Technically, it will be known as earth satellite station Standard A , while the Arua station is known as Standard B . For the layman, however, the basic structural features of the two main types of earth stations are more or less the same in appearance the main apparent difference being in their relative sizes. Each consists of a domediapcd structure or antenna, sometimes called the dishy, a microwave link tower, a Sower station with stand-by iesel power generators, and administrative offices. The TV link is two-way capable of receiving and transmit. ting, telecasts between the International Telephone Exchange in Kampala, and the UTV studios at Nakasero Hill. Similarly, the microwave Halt is for telephone and TV signals between the earth station and the International Telephone Exchange. The Standard A station will have a fully electronic tejer. switching system, with an Initial capacity of 24 trunks. While the Arua standard ''B station -wfii have to use onlv one satellite station to fret its transmissions in and out of the country known as gateway station, the proposed Standard 'A** station will be capable of communicating thronen a nnmbe* of satellites at least thi««s how those In the know put It. tn a Joint TTTV-VOICE discussion, recently, with representatives of NiDDOn Electric Co Ltd (NEC) of Jaoar., contractors of the oroposad Standard A station, those of the Ports and Tel^conm:. and Ministry of Transport, Commur.lcaHons, and Works it was indicated by the Posts* Chief Project Engineer Mr Eliphaz Mbabaali, that most of the planning work for the civil work on the site, 18 km from Kampala, somewhere near Mukono, has been completed. According to the information given by the Harris Corp contractors for the Arua station the gateway station for the Arua s t a t i o n will be Goon Hilly and from there to various points, while according to the NEC renresentative. Mr Kenvi Yoda. Ren Manasrer for Communication Svs»ems Divls'on. the nror oi«ed Standard A station will be oanahle of linking with a number of countries dlrrctly. Some of the««itnks will h* on a pre-assigned basis, fba 4 is they will be permanent, while some of them will be on demand basis, that is they will be available only when required. The Arua station was a short-term project started and completed within a record time, mainly to make Uganda independent In her communications with the outside world. However, some questions have been raised since the public came to know of the Arua Satellite Station, on the deeree of independence of that station. In an earlier interview with the VOICE a Harris Corp. representative maintained that though the Goon Hillv earth station is in Briialn, according to INTEt-SSAT reflations. Britain cannot interfere with anv conrnunicatlon«from various points and ro nthe . Of course all countries, including Kenya, where the Longonot earth station Is located, have bilateral agreements with Britain for transmitting heir comm inications through the Goon Hilly gateway station. The NEC representative, Mr Yoda, auotes his comnany ^stating that: The reliabilitv of rommunications fof a Standard B s*atton^ depends on the political goodwill anh -oooeration of the government owing t » «tewav station. which imniies that some cont*ol exists on the gateway station. According to Earooq Malik, UBC's Superintendent Engineer, Goon Hilly is one of the earth stations through which many earth stations of world are linked. So Uganda would not be an exception. Malik maintains that almost all earth stations have to abide by INTELSAT regulations, to which Uganda is a signatory. Thus if a country, after agreeing to let in and out another country's communications, breaks anv of these regulations, the INTELSAT Board of Governors have the power to «'«witch off* its earth station. Basically, it seems, whether it is standard A or Standard *B from an wrtr. Station, signals have to be transmitted to a satellite, stationed about 36,000 kms in orbit owned by INTELSAT. Except in very rare case», and from there to either other earth Stations or directly to various points. The oroooeed Uganda Standard A s*at»on will have direct communication wtth Mvw destinations: Zaire, Nigeria, USA, UK. West Qermany, Italy, and Saudi Arabia. Thee» will be on a pre-asstgned baue . It wm also have direct «om. munfoamon with SI desttna- Uone on demand assigned basis. These Include several countries In Urttn America, North America, Africa, Westcm and Eastern Europe. While the Ann station will have a capability of 24 channels, the Standard A J*a«on will be equipped withi'is* channels, which can be extended to 97t channels, on a preasslnged basis. It will have an additional capacity of 13 channels, which can be extended to 60 chanels. All of these combined will be capable of receiving and transmitting telephone, radio, telex, and TV (colour of monochrome) signals. In the IcJnt UTV-VOICE olscusslon, attended also by Mr Louis Kerullk, Under Secretary. Communications, Ministry of Transport, Communications and Works, I was interested In knowing how the proposed satellite station would affect the already eomnteted Standard B station In Arua. Win ft make «he Arua station obsolete or w«n H h«n««s- Bible for the two to he coordinated to stmmlement each other.f The NEC representative said the two can be coordinated Jointly to serve a national and International communications system. More specifically, NEC has recommended in a (proposed?) symposium with the Uganda Government, that the Arua Standard B station be used temporarily with INTEL- SAT'S Atlantic Ocean region satellite. _ ^ When the prodosed Standard A Station is completed, by about the end of 1978, the Arua station should be repositloned to ooerate with TNTELSATS Indian Ocean region satellite. to offer Ueanda international commnnlcation with the Middle an* Ear Eastern regions Thus bv ccordmatrng and mere'ng the two stations into a sfnete national system, Uganda c« t»d have a complete global International eommunfoatton as Is the ease, reports NEC In Ecvot. Libyan Jamahirlyah, and Poland. Alternatively, NEC is recommending that the Harris bout Standard B station be totallv integrated into the existing domestic satellite communications network in Uganda. It will be im to the Uganda government to consider and decide these recommendations. If and when that Is accented and implemented, according to what the wizards say, most regions of the world win be within reach of Uganda on the tonch of a button. Remember, 1978 is not so far away. o o OQC l- ii UQ OT oc5 w-j 0 3:2 g * H fc (/ CSO: 5500 z«2 9 AUSTRIA INTERNATIONAL SATELLITE BROADCASTING POLICIES DEBATED IN VIENNA Frankfurt/Main FRANKFURTER ALLGEMEINE in German 5 Jul 77 p 2 [Article: Discussion of Future Legal Maxims in Space ] [Text] Ko. Vienna, 4 July. Is a state that undertakes direct television transmissions via satellites obligated to request permission of a receiverstate before broadcasting into that state's territory? This question gave. rise to tough debates at the 20th conference of the UN-Committee for the Peaceful Utilization of Space, which came to an end over the weekend in Vienna. Through the frequencies for direct transmissions via satellites given away to interested states by the International Telecommunication Union (ITU) in Geneva in January of this year a certain delimitation was, indeed, attained, but the question of the intentional or unintentional overspill, the transmission of broadcasts into the territory of neighboring countries, was not solved by this. Technically such an overspill cannot be completely eliminated. It would be easy, on the other hand, to amplify it still further. The fundamental question remains, therefore, what rights a state is to have which is the victim of the transmission of direct television broadcasts via satellite not acceptable to it. In the UN Space Committee, of which 37 states are members -- only 34 took part in the Vienna conference though -- there was far-reaching agreement that in such cases there should be consultations and, if need be, interstate agreements between the transmitter-state and the receiver-state in order to clear up conflicts that have developed on a bilateral level. A number of states, of course -- especially those of the East bloc countries, but also various developing countries -- desire that the United Nations establish an obligatory character of such consultations with certain rights of intervention, the Western industrial states, on the other hand, are pushing for a rather loose formulation of these rules. Apart from this question, which is henceforth being further considered by a subcommittee, the Vienna meeting produced such far-reaching agreement concerning particular international principles governing the new communications medium of direct satellite transmission of television broadcasts that the Soviet delegate proposed to call them Vienna Principles -- even though they should not be launched finally until next year in a different place. The chairman of the UN Space Committee, Austria 's ambassador to the United Nations, Jankowitsch, expects these principles governing media policies to be decided in 1978 by the UN General Assembly. Thus the international political basis for the new communications system of direct television transmissions via satellites would come into existence earlier than will the technical preconditions for such television transmissions. For it will still be a few years before the individual television participant will be able to receive a television broadcast via satellite from a remote part of the world directly, without the aid of a relay station. This unusual forging ahead of the political regulation within the framework of the United Nations, according to Ambassador Jankowitsch at any rate, is an advantage because the international consensus on a subject whose consequences are not known in practice can probably be produced more easily. The principles governing direct television transmissions via satellites elaborated so far do not constitute a contractual agreement in the narrower legal sense, but rather international principles. Inter alia, they determine that such television transmissions must not conduct any hostile propaganda or stirring up the people and that they must also take into consideration the cultural values of the receiver-area. The fear that such TV transmissions via satellites could result in the introduction of disturbance factors in the receiver-country exists, of course, by no means only on the political plane, but just as much on the cultural-religious plane. Television transmissions showing barely clothed women, as they are perhaps already nearly commonplace in the Western World, would, for example, have a shocking effect in an Islamic country CSO: 5500 ITALY ATTENUATION INCREASE FOR INTENTIONAL, SERPENTINE BENDS IN LONG DISTANCE CIRCULAR WAVEGUIDE Rome NOTE, RECENSIONI, NOTIZIE in English Vol 25, Nos 3, h, May-Aug 76 pp 13U-IU7 /Article by S.
