Abstract

The private auto switching system with its operating console are often separated. By miniaturisation the two parts can be brought together in a single assembly. This is achieved using electronic components to reduce numbers of mechanical components and to reduce power dissipation. The operator console (OP) contains the keys and displays to connect a number of users (U) to the telephone network lines (6). It also houses all the transmission and control circuits (1-8). The operator equipment (1) ensures that the line (2) and tone (3) circuits are connected with the connection network (4) which is itself connected to the system junctions (5). The control unit (8) includes a microprocessor with programs stored in memories for monitoring, execution and operation of the system. One memory operates in conjunction with a call cost detector (7).
