Chapter 6: MVIP-95
Switching Data
If a Vantage PCI or RealBLOCs board is connected in an MVIP
bus, you adhere to the stream directionality of the MVIP bus.
We recommend that you use the MVIP-90 function
SET_OUTPUT to switch data over the MVIP-90 bus, but you
can also use the MVIP-95 functions for the Vantage PCI or
RealBLOCs board. You would use the MVIP-90 functions for
any MVIP-90 board in the system.
Using MVIP-90 functions
When you connect a Vantage PCI or RealBLOCs board to the
MVIP-90 bus, use the MVIP-90 function SET_OUTPUT and the
MVIP-90 stream directionality and stream numbering. The
Vantage PCI or RealBLOCs board functions like an RTNI board
with VP resources; it uses internal streams 16 and 18, and uses
DSix and DS0x streams to switch data over the CT bus.
All the concepts described in Switching Calls through the
MVIP-90 Bus on page 165 apply to the Vantage PCI or
RealBLOCs board when it is connected in an MVIP-90 bus. This
includes stream numbering and how connections are made.
When you switch data using MVIP-90 functions, you use the
internal stream 16 and 18 as described in Mapping Resources
for MVIP-90 on page 212 or, for the RealBLOCs board, see Table
33 on page 215.
