The method comprises detecting the disturbance of the transport link based on the determined properties of the transport link. The method comprises, responsive to the detecting the disturbance, determining, based on the sampled received transport data, the cause of the disturbance. The method further comprises, responsive to detecting the disturbance, refraining from transmitting an indication of the disturbance or transmitting the indication of the disturbance with an instruction for resolving the disturbance. ## Claims ### Claim 1 A method of detecting a disturbance of an outdoor microwave transport link used in a transport network, the method comprising: determining, based on sampled transport data received on a transport link, a root cause of a disturbance of the transport link; and depending on the root cause of the disturbance: if no further adjustment of an operation of the transport link is needed, not sending an indication of the disturbance; or transmitting the indication of the disturbance with an instruction for resolving the disturbance. ### Claim 2 (depends on 1) The method of claim 1, wherein not sending the indication comprises suppressing a warning indication of a declined performance for the transport data received on the transport link. ### Claim 3 (depends on 1) The method of claim 1, further comprising receiving the transport data and sampling a subset of the transport data at predetermined intervals. ### Claim 4 (depends on 1) The method of claim 1, wherein the root cause of the disturbance is caused by liquids or solids in a path of the transport link. ### Claim 5 (depends on 1) The method of claim 1, wherein the root cause of the disturbance is malfunction of equipment at an endpoint of the transport link, and wherein the method further comprises transmitting the indication of the disturbance with an instruction related to the malfunction of the equipment. ### Claim 6 (depends on 1) The method of claim 1, wherein the root cause of the disturbance is movement of the transmitter or receiver at an endpoint of the transport link, and wherein the method further comprises transmitting the indication of the disturbance with an instruction related to correcting the movement of the transmitter or receiver. ### Claim 7 (depends on 1) The method of claim 1, wherein the root cause of the disturbance is a temporary obstacle in a path of the transport link, and wherein the method further comprises selectively determining whether to: not send the indication; or transmit the indication with an instruction related to increasing transmission power of an end point of the transport link. ### Claim 8 (depends on 1) The method of claim 1, further comprising detecting the disturbance of the transport link by comparing properties of the received transport data to classes of learned channel conditions. ### Claim 9 (depends on 8) The method of claim 8, further comprising sampling the transport data received on the transport link by forming a vector of channel conditions, and wherein the detecting the disturbance comprises classifying the vector as a particular channel condition. ### Claim 10 (depends on 8) The method of claim 8, wherein the classes of learned channel conditions are based on sampling of received transport data on other transport links. ### Claim 11 (depends on 10) The method of claim 10, wherein the other transport links are selected based on their proximity to the transport link or proximity to an environmental feature. ### Claim 12 (depends on 10) The method of claim 10, wherein the classes of learned channel conditions are based on sampling of other received transport data received on the transport link. ### Claim 13 (depends on 1) The method of claim 1, further comprising detecting the disturbance of the transport link based on properties of the transport link, wherein the properties of the transport link include an attenuation of the transport link. ### Claim 14 (depends on 13) The method of claim 13, wherein the properties of the transport link further include a quality of a received signal associated with the received transport data on the transport link. ### Claim 15 (depends on 14) The method of claim 14, further comprising sampling the transport data received on the transport link to determine the properties of the transport link by sampling one or more of a received power, a transmission power, and a mean square error (MSE) associated with the received transport data. ### Claim 16 (depends on 1) The method of claim 1, wherein the transport link is a microwave transport link. ### Claim 17 (depends on 1) The method of claim 1, wherein the transport data is one or more of audio and video data. ### Claim 18 A disturbance detection apparatus for detecting a disturbance of an outdoor microwave transport link used in a transport network, the disturbance detection apparatus comprising: processing circuitry; and memory comprising instructions executable by the processing circuitry whereby the disturbance detection apparatus is configured to: determine, based on sampled transport data received on a transport link, a root cause of a disturbance of the transport link; and depending on the root cause of the disturbance: if no further adjustment of an operation of the transport link is needed, not sending an indication of the disturbance; or transmit the indication of the disturbance with an instruction for resolving the disturbance. ### Claim 19 (depends on 18) The disturbance detection apparatus of claim 18, wherein to not send an indication of the disturbance, the instructions executable by the processing circuitry configures the disturbance detection apparatus to suppress a warning indication of a declined performance for the transport data received on the transport link. ### Claim 20 A non-transitory computer readable medium comprising computer instructions stored thereon that, when executed by processing circuitry of a disturbance detection apparatus configured to detect a disturbance of an outdoor microwave transport link used in a transport network, cause the disturbance detection apparatus to: determine, based on sampled transport data received on a transport link, a root cause of a disturbance of the transport link; and depending on the root cause of the disturbance: if no further adjustment of an operation of the transport link is needed, not sending an indication of the disturbance; or transmit the indication of the disturbance with an instruction for resolving the disturbance. ### Claim 21 (depends on 1) The method of claim 1, wherein the root cause is determined using a machine learning model that compares properties of the transport data to classes representing link conditions, and wherein the classes comprise a first class representing the transport link having a normal condition and a second class representing the transport link being disturbed by rain.
