Redirected from TDM
In some TDM systems, successive pulses represent bits from successive channels, e.g., voice channels in a T1 system. In other systems different channels take turns using the channels for a group of successive pulse-times (a so-called "time slot").
What distinguished coarse time-division multiplexing from packet switching is that the time-slots are pre-allocated to the channels, rather then arbitrated on a per-time slot basis.
