A method has been proposed in which a control unit turns on the power of a terminal device (PC) and connects a line, so that a public telephone line for a general telephone and a line for a terminal device can be shared. In this conventional method, when the power of the PC is turned off at the time of the incoming call, the power is turned on. Road abnormalities cannot be dealt with. Also, Japanese Patent Application Laid-Open No. 62-227254 discloses that a calling side is a data communication device or a telephone, and if the calling side is a telephone, the receiving side waits until the called subscriber answers. A method has been proposed in which a sound corresponding to a ringing tone is transmitted from a calling side to a calling side so that the calling side can recognize that the called side operator is being called.

Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a computer telephony function which is connected to a telephone line via a telephone line connection device and performs call control management on the PC. An object of the present invention is to provide a telephone line connection device with a calling function that improves serviceability by notifying a PC user of an incoming call when call control and management cannot be performed.

[0007]

In a telephone line connection device connected using a transmission / reception unit, a communication state monitoring means for monitoring communication data between the terminal device and the telephone line connection device, and an incoming call monitoring means for monitoring an incoming call from the telephone line. A ringing tone generating means for outputting a sound corresponding to a ringing tone, and when the communication state monitoring means detects a communication abnormality, when the incoming call monitoring means detects an incoming call, on / off control of the ringing tone generating means is performed. And generating a sound corresponding to a ringing tone, and, at the time of normal communication, a ringing tone control means for turning off the tone of the ringing tone generating means even when an incoming call is received. It is characterized in.

In the telephone line connection device according to the present invention, when a call is received from the telephone network while the communication of call control information with the PC is abnormal, a telephone call is made instead of the PC. A means for generating a sound corresponding to the sound is provided. Even if an error occurs in the call control information communication between the PC and the telephone line connection device and the incoming call information from the telephone network is not transmitted to the PC, the telephone line connection is performed. The apparatus itself is configured to confirm an incoming call from the telephone network, generate a ringing tone instead of the PC, and notify the operator, whereby the incoming call can be received when call control and management cannot be performed on the PC. Is notified to the PC user, thereby improving the serviceability.
