An apparatus (100) for interfacing a telephone (12) with a telecommunications network (24). The telephone provides and accepts digital signals (118) and the telecommunications network provides and accepts analog signals (124). The digital signals include digital control content (120) and digital voice content (122), and the analog signals include analog control content (126) and analog voice content (128). A control circuit (142), a first port (106b), and a second port (110b) are provided. The first port communicates the digital signals to and from the control circuit. The second port communicates the analog signals to and from the control circuit. The control circuit converts the digital control content to the analog control content, and vice versa. The control circuit also converts the digital voice content to the analog voice content, and vice versa. |
