Digital signal transmission system

摘要: A digital signal transmission system for communicating signals in both a Faxnet and CSMA/CD mode over single cable. The includes plural stations coupled to the cable via taps, transmitting time-division multiplexed on with fixed time positions assigned within periodically repeated base frames, which frames are subjected further divisions so that individual ones of transmit packets occupy specific periods frame. send logic circuit prevents stopping from station even if collision occurs transmitted while receive reception is detected after start reception.
