Digital signal coupling field for connection between transmitting and receiving equipment

摘要

The digital coupling field (9) includes a receiving part (1), an exchange part (2) and a transmitting part (7). The receiving part includes a memory (3), a recognition part (4) and an activation unit (5). The exchange part includes transmitting equipment (27) and at least one receiver (11), connected with the coupling field through lines (20,21). This field is activated only for the switching through of the signal (after, it is automatically switched off) to the time slot for the receiving equipment or receiver.
