Abstract
A technique and apparatus allowing data transfer between multiple telephone devices on a common telephone line, e.g., to synchronize call related information such as Caller ID data. Data which may be transferred includes call related information to other devices on the common telephone line. The data transfer preferably occurs immediately after the call related information is received by a master device from the central office, e.g., between subsequent ring signals. Archival call related information relating to past incoming telephone calls may also be synchronized between the master and slave devices or between the slave devices using the data transfer.
Claims23
A customer premises equipment capable of synchronizing data with other customer premises equipment, said customer premises equipment comprising:
- a controller;
- a telephone line interface connectable to a common telephone line and in communication with said controller;
- a call related information detector/receiver in communication with said controller;
- and
- a data transfer module in communication with said controller, said data transfer module adapted to communicate with at least one other customer premises equipment in communication with said common telephone line, and to communicate with a central office indicating that said central office should not act on subsequent data transfer signaling on said common telephone line.
A method for sharing data between a plurality of telephone devices installed on a common telephone line, said method comprising:
- designating all but one of said plurality of telephone devices as slave telephone devices;
- indicating to a central office that data transfer signaling on the common telephone line should not be acted on;
- and
- transferring data between said all but one telephone devices and said one telephone device over said common telephone line.
Apparatus for sharing data between a plurality of telephone devices installed on a common telephone line, said apparatus comprising:
- means for designating all but one of said plurality of telephone devices as slave telephone devices;
- means for indicating to a central office that data transfer signaling on the common telephone line should not be acted on;
- and
- means for transferring data between said all but one telephone devices and said one telephone device over said common telephone line.
