INTERFACE CIRCUIT FOR CONNECTING A DIGITAL EQUIPMENT TO A TIME MULTIPLEX LINK

摘要

Interface circuit for connection (1) of a data emitter-receiver digital equipment (2) to a time multiplex link (3). The connection interface circuit is provided with a bit emission terminal (3E1) and with a bit receiving terminal (3R1) enabling to connect the interface circuit to corresponding wires (3E, 3R) of a time multiplex link (3) in parallel with other interface circuits (1 or 8) of digital data or speech signal emitter-receiver equipments (2) or (4) respectively. It comprises a synchronization arrangement (12) enabling to connect the interface circuit to the multiplex link (3) in the same way as for interface circuits (8) of speech signal emitter-receiver equipments (4) and it is automatically adapted to the rate possibilities offered by the multiplex link.
