Zusammenfassung:	A system for communicating between a downhole tool and a surface location. The system may include a downhole tool disposed within a subsea riser. The downhole tool may include a device that actuates between first and second positions. An internal transducer may be coupled to the downhole tool and transmit a signal indicative of the position of the device. An external transducer may be positioned on an exterior of a riser. The external transducer may receive the signal from the internal transducer through the riser. A transponder may be positioned on an exterior of the riser and coupled to the external transducer. The transponder may transmit a signal to a surface location indicative of the position of the device.
