Queries
Queries request specific information from an SSPA. They can be directed to the SSPA
system controller or an individual SSPA unit by selecting the appropriate unit ID. Table
3-22 contains a list of the valid queries the M&C can issue and the corresponding
response. Only one query can be sent at a time and the M&C system should wait until a
valid response is returned from the SSPA system before sending another query.
