PROBLEM TO BE SOLVED: To provide a computer telephony interface adapter (CTIA) for interfacing a computer device, a telephone set and a telephone network. SOLUTION: The CTIA communicates with the telephone network using a telephone network protocol, such as a PSTN or PBX protocol, and communicates with a POTS telephone set or a PBX telephone set according to the telephone network protocol and with the computer device according to a data communication protocol, such as a USB or wireless protocol. The CTIA includes a controller in a state of communicating with the telephone network, the telephone set, and the computer device. The controller converts communications between the telephone network protocol and the data communication protocol and further selectively couples the telephone set in a communicating state to the telephone network and the computer device at the same time. Thus, the CTIA enables local control over real-time shared communications among the telephone set, the telephone network, and the computer device. COPYRIGHT: (C)2005,JPO&NCIPI
