Japanese editions of the Financial Times have been successfully transmitted from London to Tokyo via a managed network for around four weeks now, and Wokingham, Berkshire-based General DataComm Ltd is eager that people are aware that its time division multiplexers are playing an important part in the feat. Copy is firstly transmitted by a Megamux II from the FT’s Southwark Bridge office to the new printing plant on the Isle of Dogs via both British Telecom and Mercury 2Mbps lines; output is then compressed at a rate of 10:1 and transmitted by another Megamux II to British Telecom International’s satellite communications facility next to Vauxhall Bridge, London SW. Intelsat provides the final link to further Megamux systems in Japan. Similar systems have been receiving the news in Frankfurt, West Germany, New Jersey, US and Roubaix, France for some time; with the Tokyo pact the General’s orders with the Financial Times now top UKP500,000.
