摘要：
The switching network is tested by comparison of bit streams coming from the double part switching network parts; other parts of the exchange are tested by parity checking. Evaluation takes place at a central location; when a parity error is found in the transmission in a direction of transmission, the parity bit generated for transmission in the other direction of transmission is falsified.
