    摘要： An information terminal incorporates a network interface and an extension interface, and in the case of outside call, an audio send signal is modulated into an audio signal frequency band, and sent to the exchange through a private telephone line and a subscriber's line by way of the network interface. An audio receive signal sent from the exchange through the subscriber's line and private telephone line is demodulated into an ordinary audio frequency band through the network interface. On the other hand, in the case of extension service, an audio send signal is converted into a packetized digital signal by an extension interface circuit, and is further modulated into a higher frequency band so as not to overlap with the audio signal frequency band, and is transmitted through the private telephone line.

    摘要： A calling side ISDN terminal adapter (TA) judges if Internet call is possible or not when the telephone number of a destination side telephone set is specified by a calling side telephone set. If judged possible, a predetermined number, and ciphered Internet connection member identification number and password are set on the sub-address of call setting, and sent out to a destination side ISDN TA. When receiving the predetermined number, the destination side ISDN TA rings the bell of the destination side telephone set, and when it is off the hook, it connects to the destination side access point by the Internet connection member identification number and password, and notifies the calling side ISDN TA by putting the destination side IP address acquired at the destination side access point on the sub-address of call setting.

    摘要： To prevent a calling party from paying an Internet connection fee when a called party is busy, in an Internet telephone, a call setting message including a sub-address to the called party is used to notify the called party of an incoming call which can be placed through the Internet. ISDN terminal adapters of the calling party and the called party are automatically connected to access points to the Internet to reduce the telephone rate when using the Internet.
