Abstract
In a telecommunication system with a number of units (Ula-Una, Ulb-Unb) for control purposes and also for subscriber facilities, each such unit is duplicated, as is the system controller (SCa, Scb). There are two local area networks (1,3), each of which interconnects one system controller and one unit of each pair of units. When one network is to be isolated, e.g. for servicing or when a fault occurs, its controller detects that condition, and isolates that network by relay circuitry in the termination (T2, T3) of the bus. Another version of the system uses local area networks of the closed ring type. In certain cases the units, etc., may be triplicated.
