To establish a link on a data path, the four functional blocks, buffer, SART, data pump and IOM-2
interface must be configured first. Since the configuration of the data pump will reset the whole data
path except buffer configuration, the pump should be configured right after buffer configuration.
It is recommended to follow this sequence to provide for proper operation.
The table below shows the configuration parameters for each of the four blocks and the reference to
the corresponding parameter setting.
Detailed information about the individual parameters is provided with the corresponding configuration
setup messages.
