Abstract
PURPOSE:To improve the transmission quality of a transmitting path system by sending a specified pattern to a spare line and executing supervision. CONSTITUTION:A signal is sent from a low order group multiplex converting equipment 1 to a switching transmitting system 6. In the switching transmitting system 6, a switching equipment 2 transmits the signal from the low order group multiplex converting equipment 1 through terminal stations 31 and 32 to living circuits 41 and 42. A signal from a specified pattern generating and detecting circuit 5 is sent to a spare line 4. In a reception side, since the specified pattern sent by the spare line 43 is detected by a detecting circuit 5', a transmitting path fault or the fault of the switching equipment 2 or a terminal station equipment 3 can be discriminated. After the switching to the spare line, an error is not detected in a low order group device.
