A two-line videophone can be used to initiate video communication while maintaining audio communication throughout the initiation period. A user uses a first line to initiate an analog voice call with another user. The videophone then uses a modem to initiate a video (including image and voice) link on a second line. During this initialization period, the first line continues to carry the analog audio communication. After the video link on the second line is established, voice communication can be switched to the second line. The system then uses another modem to initiate a separate video link on the first line. During the setting up of the digital link on the first line, video communication (including voice and images) continues to be carried on the second line. Consequently, there is no gap in audio communication. After the digital link on the first line is established, both the first and the second lines can be used to carry video communication.
A method for connecting a first and a second device using a plurality of telephone lines, said first device containing a first modem connected to a first telephone line associated with a first telephone number and a second modem connected to a second telephone line associated with a second telephone number, said second device containing a first modem connected to a third telephone line associated with a third telephone number and a second modem connected to a fourth telephone line associated with a fourth telephone number, said method comprising the steps of:
