Patent DE-4018383-A1 (DE)
Inventor: HEGENBART BRIGITTE
IPC: H04M3/50
Filed: 1990-06-08
Abstract: 2.1. A method is to be proposed with which a multiplicity of additional facilities which are useful for communication exchanges can be implemented with no need for substantial initial outlay in the standard version. Existing structures are to be used in such a way that no existing methods need to be modified when new facilities are added. The existing signalling paths between the control devices are to be incorporated in the method in such a way that connection paths need to be switched only if voice transmission is to take place. 2.2 A processing unit is provided which is connected via a bus line system to the local group controllers and the central controller and which can exchange information with these controllers. The processing unit is instructed from a data terminal to establish a connection when a predetermined time or event occurs, or, in the case of specific facilities, independently detects that a connection is to be established for data and/or voice. The group controllers involved in a connection are then controlled by the processing unit as if the connection had been established directly from a terminal. 2.3 When a new facility is set up in the processing unit, no consideration needs to be given to structures or programs already present in the communication exchange. The central control device carries a lighter load because the processing unit and the local controllers can exchange information directly with one another. The switching network available for establishing connections carries a lighter load because, for example, connections do not have to be established via it for data entries. A multiplicity of solutions optimally adapted to specific commercial applications are possible. <IMAGE>

The container system can have a base and cover plate which are each profiled on their side facing the stack whilst their outside is smooth so that several container systems can be stacked up. USE/ADVANTAGE - The container system can store different types of workpieces.
