Abstract

1. A central control unit of a switching system, in particular a telephone switching system with a plurality of processors (BP, CP) which are of fundamentally-identical construction and which can be provided with individually-assigned stores (LMY) which carry out distributed switching-orientated functions and which, in the event of a funtional failure, are represented by another of the processors and a central bus system (B : CMY) to which the processors (BP, ZP) are connected, characterised in that only two processors (BP), serving as so-called base processors (BP), additionally carry out operational and/or security-orientated functions in such manner that the first base processor (BPO), namely the controlling processor of the two processors, thus in the controlling state, is capable of carrying out alone these instantaneous operational and/or security-orientated functions but for this purpose is only partially loaded, namely up to x % of its computing capacity, so that up to (100-x)% of its computing capacity can additionally assume switching-orientated functions, the second base processor (BP1) which is in the non-controlling state, is equipped in such manner that it always keeps available at least x % of its capacity in order to possibly later take over the control of the operational and/or security-orientated functions from the first, previously-controlling base processors (BPO), the second base processor (BP1) is thus suitable, prior to assuming control, to itself undertake switching-orientated functions in respect of a maximum of up to (100-x)% of its capacity.
