Abstract
A method for connecting a local and a remote device using a plurality of telephone lines is disclosed. The remote device calls the local device on one of the telephone lines to establish a first telephone connection. The local device sends the other telephone numbers to the remote device on the first telephone connection. The remote device can then establish additional telephone connections. Once connections are established, the two devices can divide a data stream into smaller components. These components are sent via these telephone connections. These components are received by the receiving devices and combined to recover the original data stream. One of the application of the present invention is videophone.

A method for connecting a local and a remote device using a plurality of telephone lines, said local device containing at least a first and a second line system connected to a first and a second telephone line associated with a first and a second telephone number, respectively, said remote device containing at least a first and a second line system connected to a third and a fourth telephone line associated with a third and a fourth telephone number, respectively, said method comprising the steps of:
- dialing, by said first line system of said remote device, said first telephone number to initiate a first call to said first telephone line;
- receiving said first call on said first telephone line by said first line system of said local device, thereby establishing a first telephone connection;
- sending said second telephone number by said local device to said remote device on said first telephone connection;
- dialing, by said second line system of said remote device, said second telephone number to initiate a second call to said second telephone line;
- identifying, by said local device and prior to establishing a second telephone connection, said second call as originated from said remote device;
- receiving said second call on said second telephone line by said second line system of said local device, thereby establishing said second telephone connection;
- said remote device dividing a data stream and transmitting divided data to said local device using both of said first and said second telephone connections;
- and
- said local device receiving and combining said divided data to recover said data stream.
A method for connecting a local and a remote device using a plurality of telephone lines, said local device containing at least a first and a second line system connected to a first and a second telephone line associated with a first and a second telephone number, respectively, said remote device containing at least a first and a second line system connected to a third and a fourth telephone line associated with a third and a fourth telephone number, respectively, said method comprising the steps of:
- dialing, by said first line system of said remote device, said first telephone number to initiate a first call to said first telephone line;
- receiving said first call on said first telephone line by said first line system of said local device, thereby establishing a first telephone connection;
- sending said second telephone number by said local device to said remote device on said first telephone connection;
- dialing, by said second line system of said remote device, said second telephone number to initiate a second call to said second telephone line;
- receiving said second call on said second telephone line by said second line system of said local device, thereby establishing a second telephone connection;
- said remote device dividing a data stream and transmitting divided data to said local device using both of said first and said second telephone connections;
- said local device receiving and combining said divided data to recover said data stream;
- and
- identifying, by said local device, said second call as originated from said remote device, said identifying step comprising the steps of:
- sending said fourth telephone number to said local device;
- and
- detecting, by said second line system of said local device, a caller-ID number that corresponds to said fourth telephone number.
A method for connecting a local and a remote device using a plurality of telephone lines, said local device containing at least a first and a second line system connected to a first and a second telephone line associated with a first and a second telephone number, respectively, said remote device containing at least a first and a second line system connected to a third and a fourth telephone line associated with a third and a fourth telephone number, respectively, said method comprising the steps of:
- dialing, by said first line system of said remote device, said first telephone number to initiate a first call to said first telephone line;
- receiving said first call on said first telephone line by said first line system of said local device, thereby establishing a first telephone connection;
- sending said second telephone number by said local device to said remote device on said first telephone connection;
- dialing, by said second line system of said remote device, said second telephone number to initiate a second call to said second telephone line;
- receiving said second call on said second telephone line by said second line system of said local device, thereby establishing a second telephone connection;
- said remote device dividing a data stream and transmitting divided data to said local device using both of said first and said second telephone connections;
- said local device receiving and combining said divided data to recover said data stream;
- identifying, by said local device, said second call as originated from said remote device, said identifying step comprising the steps of:
- receiving, by said second line system of said remote device, a ringback signal;
- sending an acknowledgment signal to said local device by said remote device indicating the receipt of said ringback signal;
- receiving, by said second line system of said local device, a ring signal;
- and
- identifying said second call as originated from said remote device when said acknowledgment signal and said ring signal are received by said local device;
- and
- wherein said acknowledgment signal further includes a signal identifying said second line system of said remote device.
A method for connecting a local videophone and a remote videophone using a plurality of telephone lines, each of said videophones containing a video codec and an audio codec, said local videophone containing at least a first and a second modem connected to a first and a second telephone line associated with a first and a second telephone number, said remote videophone containing at least a first and a second modem connected to a third and a fourth telephone line associated with a third and a fourth telephone number, said method comprising the steps of:
- dialing, by said remote videophone, said first telephone number to initiate a first call to said first telephone line;
- receiving said first call on said first telephone line by said local videophone, thereby establishing a first telephone connection;
- sending said second telephone number by said first modem of said local videophone to said first modem of said remote videophone on said first telephone connection;
- dialing, by said remote videophone, said second telephone number to initiate a second call to said second telephone line;
- identifying, by said local videophone and prior to establishing a second telephone connection, said second call as originated from said remote videophone;
- receiving said second call on said second telephone line by said local videophone, thereby establishing said second telephone connection;
- said remote videophone dividing a video data stream and transmitting, using both said first and said second modems of said remote videophone, divided data to said local videophone;
- and
- said local videophone receiving said divided data using said first and said second modems of said local videophone and combining said received data to recover said data stream.
