A computer interface that allows an ADSI CPE to act as a user interface to an application program running on a PC. The invention is embodied in a PC telephone interface card that is connected between an ADSI CPE and a PC application. Communication is in accordance with the ADSI protocol, which allows for the display of character strings on the ADSI display screen, the downloading of scripts to the ADSI CPE, and the programming of softkeys on the ADSI CPE. The telephone interface converts DTMF tones received from the ADSI CPE to corresponding characters and sends these characters to the application program, and converts DTMF and FSK characters received from the application program to corresponding tones to transmit to the ADSI CPE. The interface can be connected to a network for computer or IP telephony functionality.
