Two-way data transfer apparatus

---

Abstract

---

A two-way data transfer device for the data interface between two data-exchanging cells including a data source and a data sink with at least one buffer provided in each cell. When the transmitter buffer is full or the receiver buffer is empty, a backward cell stop signal freezes the state of the data source or the data sink and the cell stop signals are controlled by status signals from the respective buffers.
