The time-switch
nOne of the time slots of any
full-duplex lines is connected to the line (at the time)
nThus
two switches / time slot connect a line
nFor
100 full-duplex lines at 19.6 kbps a 1.92 Mbps bus is thus required for
no blockingnIf no fixed assignment of input lines to time slot but on demand allocation
-> blocking switch that reduces number of switches and switch clock
frequency. For instance 200 devices of 19.6 kbps with bus of 2 Mbps -> about half of the
devices can connect at any time
