The LAN system is a developement of the WELNET (TM) system, in which scheduling arrangements between the stations is controlled by a scheduling channel (40) in the form of a loop, separate from the main information channel (32). The invention provides for Voice and Data to be integrated on the LAN. On a periodic cycle (70), scheduling is interrupted, and each station is invited to put a Voice packet on the main channel. When the system goes back to Data, the system is so configured as to resume at the station which was about to transmit Data when the schedule was interrupted for Voice. |
