Title: Multi-processing stored program controlled telecommunication establishment.
IPC: H04M3/36
Filed: 1984-09-28
Abstract: Central and regional processors (1,2) are connected to an independent stored program controlled co-operative signal switching system (3). The system processor (4) controls a co-operation instruction memory (8), co-operation function blocks (9,10.12.13) for buffering the cooperative signals, and priority determining function blocks (11,15) for determining the consecutive order in which incoming signals are switched and for associating priority levels with signals addressed to central processors. - The signal switching system (3) performs with the aid of a function block (16) for flexible control load distribution, a redistribution of control load, and/or reduces signal switching to a central processor if the latter is overloaded.  (1/1) EPAB- EP-157819 B Stored program controlled telecommunication establishment, the controlled and controlling parts of which comprise a plurality of establishment function blocks (2) which perform telephony functions and computer functions with the aid of instruction memory units and data memory units for storing establishment control information, and a plurality of processors which include at least one central processor (1), said function blocks and processors controlling in real time and in mutual co-operation the telephony traffic processed by the establishment with the aid of the stored control information, the co-operation functions containing determination of the consecutive order in which the establishment function blocks perform their assigned functions, characterised by an independent stored program controlled signal switching system (3), which executes said co-operation functions by switching co-operative signals between said establishment parts, which includes a co-operation memory (7-16) for storing co-operative control information and which includes one (4) of the processors, which exclusively controls in real time said signal switching system with the aid of the stored co-operative control information.  (9pp) USAB- US4731817 A In a stored program controlled telecommunication establishment, function blocks (2) of the establishment are controlled in cooperation with a computer system including a number of processors (1,4). Determining the order in which the establishment control functions are preformed is included in the cooperative functions. One of the processors is separated for exclusively controlling an independent stored program controlled signal switching system (3) which performs the cooperative functions by switching cooperative signals between the function blocks (2) of the establishment and at least one central processor. The signal switching system processor (4) controls a cooperative instruction memory (8), cooperative function blocks (9,10,12,13) for buffering the cooperative signals, and priority determining function blocks (11,5) (11,15) 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 (3) performs, with the aid of a function block (16), for flexible control load distribution, a redistribution of control load, and reduces signal switching to a central processor if the latter is overloaded.
