Embodiment Construction
[0050] figure 2 Shows the optical network transmission system port ID encryption and decryption enabling switching method of the present invention, such as figure 1 Shown, method of the present invention comprises the following steps:
[0051] The central office equipment OLT obtains the port ID encryption and decryption enabling switching mode supported by the ONU through negotiation with the user equipment ONU;
[0052] After the OLT obtains the port ID encryption and decryption enabled switching mode supported by the ONU, by sending an activation request to the ONU, the ONU adjusts its port ID encryption and decryption enabled switching mode to the synchronous encryption and decryption enabled switching mode of the present invention. ;
[0053] In the synchronous encryption and decryption enabling switching mode, the OLT and the ONU determine the switching time for simultaneous encryption and decryption port ID enabling switching, so as to simultaneously complete the encry...
