At least one receiver port is switchable between a blocked state, wherein the data received by the port is automatically erased, and an unblocked state, wherein the data received by the port is stored for later processing. The equipment includes a security module configured to switch a respective receiver port from its blocked state to its unblocked state for a predefined transmitter equipment group after receiving a valid authentication message issued by the transmitter equipment group in response to an authentication request sent to the group by the security module.
