The present invention discloses an OTN scheduling system and a troubleshooting method. The method comprises a step of detecting the link between the nodes of a core layer which bears a PTN, wherein, the links between a core and the nodes are borne by at least routing cables in an OTN, a step of switching the routing cable which bears a fault link when the link fault between the core nodes is detected.
