Then you have time division multiplexing. A token ring network could be seen as an example of that, but not really. Rather an evolution of it. Or other bus arbitration techniques. That's for digital world. On the analog world, you can use frequency multiplexing (AKA tuning wheel in a plain kitchen radio). Same thing as used on cable networks carrying many analog TV channels. Similar to what is done on copper phone lines to transmit ADSL. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
