ONU Authentication Method Based on POTS Key Matching

摘要

A new ONU authentication method based on POTS key matching is proposed, which makes use of ONU's own FXS resources and connects with a pots phone by dialing the corresponding LOID service key and authentication code that will be sent to ONU. The key combined with LOID service key and authentication code received by ONU will be filtered and then the LOID authentication code is obtained, which is put to match with DigitMap preset into the database of ONU. The LOID authentication code will be transmitted to OLT so as to achieve the purpose of ONU authentication and authorization if the match result is successful.
