Scicon Networks Ltd is ready to start installations of its RISC-based 200Mbps voice and data ISDN Ringswitch: the ISDN Ringswitch, developed with Cambridge Consultants Ltd, consists of two fibre optic rings around which traffic circulates in opposite directions – if one ring is broken, traffic is automatically transferred to the other, and if both go down, the ring is configured to form a horse-shoe-shaped link with, claims Milton Keynes-based Scicon, no loss of performance; connection times are put at less than 100mS, and apart from use by any organisation that requires the level of fault tolerance it provides, Scicon also suggests that it could be well used as part of a digital cellular network; the ISDN Ringswitch starts at around UKP30,000 for a single node, although Scicon reckons that most applications are best served by a bare minimum of at least two nodes.
