Abstract
A system and method for a Universal Serial Bus (USB) device supporting both PSTN and DECT external interfaces. A USB device has distinct and dedicated external interfaces for providing multi-functionality capabilities. The host PC coordinates device interfacing through separate interface drivers associated with the USB device external interfaces. Future replacement of either external interface functionality is allowed without effecting the host PC driver or firmware architecture.
Claims9
A computer telephony system comprising:
- a host computer;
- a bus connected to the host computer and configured to carry isochronous data;
- and
- a peripheral device connected to the bus, the peripheral deice having a common control interface and at least two external interfaces configured to support access to at least two different communication networks.
An apparatus for use in a computer telephony system having a host computer and a bus that is connected to the host computer and configured to carry isochronous data, the apparatus comprising:
- a common control interface arranged to be connected to the bus;
- and
- at least two external interfaces arranged to be connected to the bus and to at least two different communication networks, and configured to be responsive to one more signals from the common control interface.
A method for use in a computer telephony system having a host computer and a bus that is connected to the host computer and configured to carry isochronous data, the method comprising:
- providing a common control interface within a peripheral connected to a isochronous configured bus;
- using a first external interface within the peripheral device to connect the bus to a first type of communication network, the first external interface being responsive to one more signals from the common control interface;
- and
- using a second external interface within the peripheral device to connect the bus to a second type of communication network, the second external interface being responsive to one more signals from the common control interface.
