MULTI-PROCESSING STORED PROGRAM CONTROLLED TELECOMMUNICATION ESTABLISHMENT

摘要

In a stored program controlled telecommunication establishment, function blocks of the establishment are controlled in co-operation with a computer system including a plurality of processors. Determining the order in which the establishment control functions are performed is included in the co-operative functions. One of the processes is separated for exclusively controlling an independent stored program controlled signal switching system which performs said co-operative functions by switching co-operative signals between the function blocks of the establishment and at least one central processor. The signal switching system processor controls a co-operation instruction memory, co-operation function blocks for buffering the co-operative signals; and priority determining function blocks for determining the consecutive order in which incoming signals are switched and for associating priority levels with signals addressed to central processors. An establishment with a flexible control load is obtained with the aid of supervision of the signal quantity fed to the central processors. The signal switching system performs, with the aid of a function block, for flexible control load distribution, a redistribution of control load, and/or reduces signal switching to a central processor if the latter is overloaded.
