As part of its dowry to Dowty Group Plc, Case Group Plc will bring a spicy little OEM contract with IBM UK Ltd for specialised interface units that convert X21 signals to the G703 standard: this will enable IBM’s 3737 Remote Channel-to-Channel Adaptor and 3745 Communications Controller, which were designed for the US 1.544Mbps T1 lines, to interface to the European 2Mbps standard used in the British Telecom MegaStream fast digital service.
