Considerations Does the recorder
system have enough PCI
slots?
„
Most mainstream servers max out at
3 PCI slots
„
Expansion chassis is often needed
„
A TDM bus cable is not required,
so that cards can be split between
the host system and an external
chassis
„
Performance can degrade if there
are more than 4 PCI bridges
between the host CPU and the cards
„
PCI Express expansion chassis can
be used.
