摘要：A method of transmitting data packets in a message-switched channel

(signalling channel) of a time-division multiplex system with CSMA-CD. Interference-freetransmission in the message-switched channel ensures the absence of collisions onoccupying the circuit-switched connection. Message mutilation and collision on accessingthe message-switched channel are remedied by a retransmission procedure in which theunique station address number determines the frame number in which the retransmissionmay start. This procedure guarantees that a station accesses the message-switchedchannel within a very short period of time. This guaranteed access is not possible with theprior art CSMA-CD buses.
