Connecting Boards in an MVIP-90 Bus
Setting the Clock Parameters
Configure the clock parameters using the Configuration Wizard
during software installation. For specific information about the
Configuration Wizard, see the installation and configuration
guide that came with your software.
If you want to change your configuration after software
installation, use the MVIP-90 function CONFIG_CLOCK, as
described in Configuring the MVIP-90 Clock on page 150. You
would set the clock for the Vantage PCI board similar to an
RTNI-ATSI or RealBLOCs board: It should only drive the clock
if there is no T1 or E1 in the system and it drives the clock from
its internal oscillator.
You can also use the
MVIP95_CMD_CONFIG_BOARD_CLOCK MVIP-95 function
to set the clock. Use the MVIP data structure to set the
compatibility clocks for MVIP-90. We do not recommend using
the MVIP-95 function if your H.100 compliant board is
connected in an MVIP-90 bus.
Configuring the H.100 Stream Speed for the
MVIP-90 Bus
The MVIP-90 standard only supports 32 timeslots and 16
streams, so an H.100 compliant board connected in an MVIP-90
bus can also only use 32 timeslots, or a speed of 2 MHz, for its
first 16 streams.
For example, if you have a Vantage PCI or RealBLOCs board
and an RTNI-ATSI connected in an MVIP-90 bus, set the first
16 streams of the Vantage PCI or RealBLOCs board to use a bus
speed of 2 MHz, which is the default value for those streams.
For an example of how to configure stream speeds, see
Example 13 on page 205.
