Radio equipment (RE) endowed with an automatic redundant architecture comprising a plurality of Point of Interface units (POI1; POI2, POI3) provided with: - a Slave port (S) able to receive a link; and - at least a Master port (M) able to forward the link incoming in said Slave port (S); - at least a Redundant port (R) with same Slave port (S) capabilities; wherein: - a first Point of Interface unit (POI1) has said Slave port connected to a corresponding first Master port (CPRIO) of a radio base station (BTS) and said at least a Master port (M) connected to a Slave port (S) of at least one of the others Point of Interface units (POI2, POI3); a second Point of Interface unit (POI2) has said Redundant port (R) connected to a corresponding second Master port (CPRI3) of said radio base station (BTS) and said at least a Master port (M) connected to a Redundant port (R) of at least one of the others Point of Interface units (POI1, POI3); wherein, for each of said Point of Interface units (POI1, POI2, POI3), the radio equipment (RE) is configured to execute at least a step of detecting the presence/absence of an input link on said slave port (S), and wherein in case of detection of the absence of an input link on said slave port (S), radio equipment (RE) is configured to execute at least the following steps: - switching off of said at least a Master port (M); - activating said redundant port (R); - checking if a redundant (CPRI) link is available on said redundant port (R); - if a redundant (CPRI) link is available on said redundant port (R), forwarding said redundant (CPRI) link on said at least a Master port (M). - a Slave port (S) able to receive a link; and - at least a Master port (M) able to forward the link incoming in said Slave port (S); - at least a Redundant port (R) with same Slave port (S) capabilities; wherein: - a first Point of Interface unit (POI1) has said Slave port connected to a corresponding first Master port (CPRIO) of a radio base station (BTS) and said at least a Master port (M) connected to a Slave port (S) of at least one of the others Point of Interface units (POI2, POI3); a second Point of Interface unit (POI2) has said Redundant port (R) connected to a corresponding second Master port (CPRI3) of said radio base station (BTS) and said at least a Master port (M) connected to a Redundant port (R) of at least one of the others Point of Interface units (POI1, POI3); wherein, for each of said Point of Interface units (POI1, POI2, POI3), the radio equipment (RE) is configured to execute at least a step of detecting the presence/absence of an input link on said slave port (S), and wherein in case of detection of the absence of an input link on said slave port (S), radio equipment (RE) is configured to execute at least the following steps: - switching off of said at least a Master port (M); - activating said redundant port (R); - checking if a redundant (CPRI) link is available on said redundant port (R); - if a redundant (CPRI) link is available on said redundant port (R), forwarding said redundant (CPRI) link on said at least a Master port (M). - switching off of said at least a Master port (M); - activating said redundant port (R); - checking if a redundant (CPRI) link is available on said redundant port (R); - if a redundant (CPRI) link is available on said redundant port (R), forwarding said redundant (CPRI) link on said at least a Master port (M). <EOS>
