ABSTRACT:
In a telephone installation, telephone rental data is loaded remotely into an independent station in the following manner.
In response to a request for a call coming from the independent station and in the presence of a load request signal, a control means searches all the telephone rental data relative to the independent station as well as that indicating an order for the remote loading. A coding means codes with the help of a special key data which is secret. A processing means authorises the transmission of non-secret pubic telephone rental data as well as secret data thus encoded to the said independant station according to the order for the remote loading.
At the independent station a decoding means deciphers the coded secret telephone rental data thus received with the help of the special key and a processing means stores the non-secret public telephone rental data thus transmitted and secret data thus decoded in a memory of the independent station.
