Abstract
The call distribution system is designed for operative positions in telephone exchanges, in particular for time multiplexing exchanges. The exchanges having cyclic circulation memories for establishing connections. A common distribution call distributor (AV) distributes each call to a free position. This is achieved because the memory line, of the memory establishing connections attributable to the call, is marked in an individual marking memory (MSP) for each position. The marking memory (MSP) is operated in synchronism and in parallel with the connection establishment memory. By enfichage of the operative positions using data delivered by the marking memory (MSP), the address of the respective operative position as well as the call state is recorded in the connection establishment memory. The data in the marking memory being again erased.
