摘要
The present invention relates to a hybrid fiber & coaxial network, and more particularly, to a hybrid fiber & coaxial network in which, when a call is requested from a user to a transmission apparatus side in a telephone service using the corresponding optical axis hybrid network, To a telephone security system and method in a mixed optical communication network.;It is easy to eavesdrop on the telephone conversation in the conventional optical communication system of the present invention. However, according to the present invention, the timer unit for synchronizing the processing of both the inside and the outside of the optical communication system and the subscriber connection device, And a cipher unit for encrypting the voice signal or decrypting the encrypted signal. The controller of the crosstalk relay apparatus receives the call request signal from the call request unit of the subscriber connection apparatus, It is possible to encrypt the voice signal by inputting the password in the signal analysis unit of the subscriber access device every time the change is made so that the subscriber can not eavesdrop the phone conversation if the password is not known even if the password is damaged.
