Bror Linden in Memonam Bror Linden It was with sorrow and a sense of loss that we received the news of the death of Bror Linden. In him we have been deprived of still another pioneer in the field of line plant construction. He was one of those who had a share in the designing of our line plant construction system and later, as constructional engineer, in taking it out into the world. Bror Linden was born in 1884, took an engineering degree in 1908. served as lines engineer at Stockholms Telefon in the years 1908-1918 and was assistant director at H. T. Cedergrens Industri AB from 1919 to 1921. He thereafter devoted his energy principally to affairs abroad. From 1922 to 1925 he was Technical Director of L M Ericsson's operating company in Poland at that time and built or modernized the local line plants in several Polish cities. He then moved to southern Italy where from 1926 to 1932. as head of Compagnia Installazioni Reti Telefoniche (CIRT). he built local line plants for the account of SET. After a few years in Sweden, where he assisted in the cabling of the Swedish Railways' telephone network in conjunction with the electrification of the railways, he went abroad again, this time to Colombia, where from 1937 to 1941 he planned and built the line plant for the City of Medellin. This was the first large local line plant of LME type in that part of the world and was therefore a reference plant not only for Colombia but also for neighbouring countries. From 1941 until he left his post in 1954 he served as Installation Manager of the Network Department. The main part of his time was spent on the leadership from Stockholm of installation work abroad. He gave generously of his great fund of experience, not only to his direct colleagues but also to the other members of the department. All of us elder members of the company who had the advantage of knowing Bror Linden will remember him with a sense of loss as a capable engineer and a man of great industry, but perhaps above all as an unusually positive personality for whom difficulties existed only to be overcome and who undertook every task in a spirit of confidence and good humour. His memory may fade but will never be effaced as long as we live. Gunnar Aberg 38
Fully Automatic Trunk Traffic in Venezuela Compania Anonima Nacional de Telefonos, Venezuela (CANTV). has initiated the largest development project hitherto in Venezuela, comprising the total modernization and automatization of the telecommunications network. During the period 1966-1970 CANTV is investing some 1000 million Swedish kronor, a record investment which within a few years will make Venezuela one of the highest developed telecommunications countries in the world. The official opening of CENTRO NACIONAL DE TELECOMLNICACIONES in Caracas was combined with the initiation of subscriber-dialled trunk traffic in Venezuela. The photograph shows the President of Venezuela, Dr. Raul Lconi, making the inaugural calls to the Governors of the Provinces of Carabobo and Aragua. (Left) The Minister of Communications, Dr. Juan Manuel Dominguez Chacin, and (right) the President of CANTV, Sr. Jorge Armand. The first stage of a national and international telecommunications centre. Centra Nacional de Telecomunicaciones. was completed on December 15, 1967. In conjunction therewith the first four transit centres under project MC-LD-15 for the introduction of fully automatic trunk traffic throughout Venezuela were opened. At the same time the first local exchange of L M Ericsson's crossbar system ARF 102 in Venezuela was put into service. Subscriber-dialled trunk traffic will be successively introduced in the twenty-nine largest towns of Venezuela during the next year, and LME has an important role in this project in the capacity of supplier of all automatic transit exchanges, comprising a multiple capacity of 6600 lines. The installation of this equipment will mean that Venezuela will be the first country in South America to have a nationwide all-automatic trunk network. Large investments have also been made in radio links. The first L M Ericsson crossbar exchange of system ARF in Venezuela, named Romulo Gallegos after one of Venezuela's greatest modern authors. The exchange has an initial capacity of 10,000 lines. The first stage of the new Venezuelan telecommunications centre, CENTRO NACIONAL DE TELECOMLNICACIONES, was officially opened on December 15, 1967, by President Leoni. The photograph shows the main building of CANTV on Avda. Libertador, Caracas. The plans include the expansion also of local exchanges, for the continued automatization of which L M Ericsson is supplying equipment totalling 69,000 lines of system ARF, of which 42,000 lines in Caracas. The first ARF exchange was cutover on December 15 in conjunction with the opening of Centra Nacional - only 10 months after the signing of the contract. 39
