A communication apparatus (100) provides an interface between a cellular encryption and decryption apparatus (150) and a telephone line (91) allowing for communication of secure data of the telephone line using a regular telephone (70). The communication apparatus (100) provides for the receipt of incoming secure data in an unattended data mode, and also allows the telephone to be used in either a secure mode or clear mode. The communication apparatus monitors the telephone line (91) for secure tones while operating in the clear mode. When a secure tone is detected, the communication apparatus (100) breaks the path between the PSTN (90) and the telephone (70) and routes the signals to the cellular encryption and decryption apparatus (150) to establish a secure call.
