Telephone arrangement for remote loading of telephonic subscription data from an autonomous station

Abstract

Abstract In response to a call request (LID) emanating from the autonomous station (SP) and in the presence of a loading request signal, the control means (UTF) investigate all the telephone subscription data relating to the autonomous station (SP) as well as that indicating the remote-loading order. The enciphering means (CDF) encipher, with the aid of the special key (EPID), those which are secret (PIN). The processing means (UTF) allow the transmission in clear of the telephone subscription data which are public, as well as those which are secret and so enciphered, to the said autonomous station (SP) as a function of the remote-loading order. <??>At the level of the autonomous station (SP) the deciphering means (CDP) decipher the telephone subscription data which are secret, enciphered and so received with the aid of the special key (EPID), and the processing means (UTP) store the subscription data which are public so transmitted in clear, and secret so deciphered in the memory of the autonomous station (SP). <IMAGE>
