1 to 4.The number of possible timeslots depends on the baud rate and the distance between the Sync-impulses.

Baudrate

L

125 kbps

Settings are possible from 100 kbit/s to 250 kBit/s in steps of 208 bit/s (@100 kbit/s) and 1295 bit/s (@250kbit/s) especially 125kbit/s and 189kbit/s.
The baud rate departs at a value of 189kbit/s with -0,0125%.
