Title
(EN) Telephone line sharing module
Abstract
(EN)
This invention concerns a telephone line sharing module. In another aspect it concerns a system for telephone line sharing. In a further aspect it concerns a method of sharing a telephone line. It also concerns a telephone interface module. It involves a telephone port, a telephone line emulator associated with the port to emulate the presence of a telephone line, a call conditioner, a telephone line port, a computer interface, and a line switch to selectively switch the telephone port between the telephone line port and the telephone line emulator. In use, the module is arranged to operate such that when a computer connected to the computer interface is using a telephone line of a network, connected to the telephone line port, and a telephone connected to the telephone port is diverted so that incoming calls are received at a gateway site which links the Internet to the telephone network, then the line switch connects the telephone port to the telephone line emulator. Otherwise, when the computer is not using the line, the line switch connects the telephone port to the telephone line port, and the telephone operates in the conventional way.
