A --16 Appendix
Dumping the scan information for both lines now indicates that we are
scanning for the offhook condition.l If the line were actually unequipped, then
we would be scanning for the "onhook from unequip" condition. This
condition would definitely indicate that the SMS is not reporting a valid
unequipped line. This is because the SMS should never be scanning for the
offhook condition when the card is unplugged. When the card is removed, the
SLC sends the unequipped AB bit pattern to the SMS. The SMS would detect
the unequipped pattern and change the scan state to "onhook from
unequipped" instead of "offhook. In order for the SMS state machine to
change to scanning for "offhook" from the unequipped state, it must first
receive the onhook AB bit pattern from the SLC. This could happen only if the
line card was installed in the SLC system.

We now look at the line config status information again to verify that the SMS
is still reporting the line as unequipped. Remember that it takes the SMS up to
1.5 minutes after the line is inserted in the SLC-96 to update the information
is this table. We will see that line 1 is still marked as unequipped even after 1.5
minutes have passed, so we definitely have an invalid unequipped line.
