Method and apparatus for high-speed data exchange

Abstract

A device is provided for rapid data exchange between a telecommunications transmitter (T) and a data processor (PC), and includes a driver (TSV) and an intermediate line (FAST-LINK). The driver (TSV) is arranged between a terminal adapter (ADAPT) of the telecommunications transmitter (T) and an interface of the data processor (PC). The intermediate line (FAST-LINK) is arranged between the driver (TSV) and the data processor (PC). The telecommunications transmitter (T) is connected to a telecommunications network (ISDN) having a signalling channel and a user channel. The telecommunications transmitter (T) has an interface circuit (S) for adjusting transmission parameters between the telecommunications network (ISDN), the telecommunication transmitter (T) and the data processor (PC), has a first layer unit (1) for ensuring that data is transmitted in both directions on the signalling channel and the data channel, has a second layer unit (2) for assigning signalling channel data to the telecommunications transmitter (T) and to the data processor (PC), has a third layer unit (3) for identifying in the telecommunications transmitter (T) all the messages from a signalling activity (Call Reference) to differentiate which devices the user channel data should be assigned, and has an operating part (4) for entering keyboard inputs and a receiver for receiving acoustical inputs and providing acoustical outputs.
