A telephone, which includes a CPU connected to a keyboard thereof, a first switch connected between first and second telephone lines, second and third switches provided at the first and second telephone lines and connected to the CPU, the second and third switches each having a first contact at the respective output end connected to a fourth switch and a second contact connected to a fifth switch, which controls a hand-free circuit, wherein when the first and second telephone lines are called at the same time, the switches are controlled by the CPU for enabling a first user to pick up one call through the hand-free circuit or talking circuit and a second user to pick up the other call through the talking circuit or hand-free circuit, and a switching can be made through the keyboard to change the connection of the telephone lines between the talking circuit and the hand-free circuit.

Telephone

The present invention relates to a telephone with an interface connection with the television, which includes a basic telephone set, central processing unit (CPU), display controller and a control program. The control program controls the whole operating procedures of the telephone of the invention. Under the operating procedures, the CPU transmits the phone-call information received by the basic telephone set to the display controller. In accordance to the received information, the display controller generates and transports a corresponding signal to a television. With the telephone of the invention, the information of a telephone call can be displayed in a television.

Telephone with interface linking to television

A method of recording the bi-directional communication between a customer premises equipment (CPE) and a server of a stored program controlled system (SPCS) in an analog display services interface (ADSI) for facilitating the troubleshooting therein is disclosed. The present invention includes accessing the telephone set by a user, therefore initiating the communication between the telephone set and the server. After receiving an alerting signal from the server, the alerting signal and the corresponding received time of the alerting signal are recorded into a trace area in the telephone set. A first acknowledgment signal is sent to the server after the alerting signal is recognized, and the first acknowledgment signal is then recorded in the trace area. At least one message is sent from the server, and then the message, a start received time and an end received time of the message are recorded into the trace area and a message buffer. Finally, a second acknowledgment signal is sent to the server, and the second acknowledgment signal is then recorded in the trace area.

Method of recording the communication between a CPE and a SPCS/server

The present invention relates to an auto-detecting dialing communication system used to make the display of caller numbers in host or communication system consist with that of an extension telephone or communication system, especially relates to an extension telephone or communication system that can also display caller numbers. The present invention offer a device for auto-detecting dialing of a parallel communication system, which composes: (1) a FSK decoder for acquiring a dial-in number. (2) an extension telephone detecting device for detecting whether the extension telephone is off hook. (3) a memory for storing the caller telephone numbers. (4) a ring-back signal detecting device for examining whether a ring-back signal is sent back. (5) a Dual Tone Multiple Frequency (DTMF) decoder for acquiring the outgoing call number. (6) a processor for sequentially proceeding with output signals of the FSK (Frequency Shift keying) decoder, the extension telephone detecting device, the memory, the ring-back signal detecting device and the DTMF (Dual Tone Multiple Frequency)decoder according to an order.
