Configuring Boards in the CT bus
There are several steps to configuring your CT bus. The
following sections in this chapter discuss these steps in more
detail.
1. Enable or disable resources.
By default, the Vantage PCI switch block is not available to
the CT bus. Enable the switch block before using the switch
block. The RealBLOCs board does not provide the switch
enable option. The switch is always enabled.
2. Configure the CT bus clock.
The CT bus uses a clock to synchronize frames. You set
which board drives the clock for the system.
3. Configure the CT bus speed.
The H.100 streams can operate at different speeds. Select a
bus speed that is compatible with the other boards in the
system.
4. Establish connections.
When you switch calls, you establish connections between a
board’s resources and the CT bus.
