The DUAL network offers both conventional (logical lines, X25, ISO 8802.3) and advanced (multicast, synchronization) services. It is based on multi-microprocessor nodes interlinked by means of fiber optics trunks. The DUAL ring is installed in a camput of several km2, interconnecting up to 40 buildings and serves as the backbone network for a number of other networks and as a test bed for the implementation of "second generation" data transmission and distributed informatics services.
