DIGITAL DATA PROTOCOL CONVERTER

摘要

A digital data protocol converter for use in transmitting packet data signals over a data transport system. The hardware converter converts data signals received from a digital telephone interface to packet data signals required by a data transport system protocol. The real-time converter also converts the data packet signal back to a digital telephone interface signal for reception at the recipient end. The converter is positioned at the access site of a data transport system and comprises a digital telephone interface for linking digital telephone lines to the converter. The digital telephone interface is attached to a transmitter and a receiver, whereby the digital telephone interface receives data signals in a digital telephone interface format and transmits this data signal to a real-time converter. The real-time converter converts the digital telephone interface data signal to a packet data signal format that is the protocol used by the data transport system. The receiver receives the packet data signals from the data transport system, the transmitter sends the packet data signals to the converter where the packet data signals are converted back to digital telephone interface signals to be routed to the recipient as digital telephone interface data signals. A method for converting digital telephone interface signals to packet data signals and for converting packet data signals to digital telephone interface signals is also disclosed.
