/NPL, Iria networks in Anglo-French link: The first test of “host-to-host” protocols between the National Physical Laboratory’s computer network and the French Cyclades network are expected to be made next week. A CTL Modular One on the NPL network is linked via Codex modems and a 9,600 baud line to one of the five CII Mitra 15s which make up Cigale, the Cyclades network switching system. Communication with the Mitra 15 mini, which is at Iria, the
Institut de Recherche d’lnformatique et d’Automatique has been at the lowest level using the IBM BSC line control protocol, which has been adopted for Cyclades because of the IBM machine on the network, and on top of that packet formats have been transmitted.
