Multi-access ATD multiplexer with congestion detection circuitry

摘要: As shown in FIG. 2 an ATD multiplexer (1-i) comprises a congestion detector (34) for detecting internal traffic when data cell stream is transferred from one of the two inputs (4, 5) to output (6). If occurs, signal transmitter (36) will supply signal. An upstream (1-j) receive this as external through receiver (37) and response thereto blocks its 5). In fashion be restricted. restricted such extent that no longer occurs (1-i), blocking blocked input removed delayed manner. The signals can transmitted over bus (10) between (6) (1-j). Thus special wire required transmitting signals.
