Mapping MVIP-90 Resources
In applications, the easiest way to determine the timeslot
assignment is with an array:
int mapping []= 1, 9,17,25
2,10,18,26
3,11,19,27
4,12,20,28
5,13,21,29
6,14,22,30
7,15,23,31
0, 8,16,24
timeslot=mapping[VP%32]
For VPS boards you call RHT_CONFIG_MVIP twice: once to set
stream and timeslot assignments for VP resources and once to
set stream and timeslot assignments for line resources. If you
set both line and VP resources to use the same timeslot offset
and stream, they are connected in channels through the MVIP
bus.
For example, if you set line and VP resources to use an offset
of 1, the first line resource will use the timeslot 1 of the DSox
stream and the first VP resource will use timeslot 1 of the
DSix stream. If you set the line and VP resources to have
different offsets, the network board controls how the line and
VP resources are used.
