DESCRIPTION
"This attribute records the slot numbers of the cards that the bus tap
considers available on the busthat is, the cards that have an
operational bus tap connected to the bus. The value of this attribute
is determined automatically by the bus tap by monitoring signals
generated by each bus tap on the bus; it cannot be changed by the
operator. Normally, every card in the module signals its availability
on both buses; if a card does not signal its availability on a bus this
indicates that the card is not present or that its bus tap has failed. By
examining this attribute for both of a card's BusTap components, it
is possible to determine which cards are present in the module and
which buses each can use.
Note: If failuresInEffect contains either selfTest or clockSignal the
bus tap is unable to monitor the availability of the bus taps on the
bus; cardsAvailable will indicate that no bus taps are available on
the bus.
