Abstract

The unit has a bus system (B:CMY), to which the processors (CP, IOC), which have their own local memory (LMY), are connected, and which is allocated sequentially to different ones of the processors (e.g. CP1, CPx, IOC0), and a main memory (CMY), which is connected to the bus system (B:CMY) and to which the processors (CP, IOC) sequentially have access via the bus system (B:CMY) in accordance with the allocations of the bus system (B:CMY). In order to carry out all the switching-oriented functions relating to special connections of telephone subscribers, e.g. speech path selection, switching through, charge accounting, call progress tone control, acceptance and recoding of call number, clear-down of connecting path, etc., the local memories (LMY) of all the processors (CP, IOC) having an at least partly identical catalogue of tasks store correspondingly identical control sections, which are required frequently or, in the case of a fault, immediately as well as data which are specially required for a single connection of two arbitrary telephone subscribers in relation to the current processing step, e.g. for the purpose of speech path selection. By contrast, in addition to control sections that are seldom required the main memory (CMY) also stores local data on a large multiplicity of current connections. <IMAGE>
