摘要:
A link for transmitting digital information is time-shared between a plurality of units under the control of one of the units called the control unit. The control unit communicates with the other units by means of individually addressed signaling cells enabling it to interrogate each unit regularly as to its current status and its requirements for communication via the link and to advise it of at least one particular frame time slot for sending a response and others for sending cells. The invention also concerns units for implementing this method.
