A method is described for checking deadlock in a telecommunication network including a first activated backup connection for protecting traffic over a first intended connection. The method includes the steps of checking a reversion blocked status of the first intended connection by checking if the segments of the first intended connection are available or not available, in case of detecting the reversion blocked status of the first intended connection identifying activated backup connections using the not available segments of the first intended connection, identifying the corresponding intended connections, checking the reversion blocked status of each identified corresponding intended connection by checking if the corresponding segments are available or not available, in case of detecting the reversion blocked status of an identified corresponding intended connection checking if a corresponding not available segment is included in the first backup connection. The method further provides the indication of the intended connections involved in the deadlock.
