Mountain View, California-based Allied Telesis Inc has introduced two Ethernet products, the CentreCOM 280 and 480, dual and four-port fanout units – fanouts are designed to reduce cabling costs and to make network expansion easier at the workgroup level, making it possible to add two or four workstations from a single transceiver connected to the backbone co-axial cable, fibre optic or twisted pair link: no outside power source is required – it’s drawn from the data terminal equipment; they are out now, at an introductory $245 for the two port, $375 for the four port unit.
