Possible States:

be routed over the backup DLCI.
●
Restore Wait

switchback timer has not yet expired. (The state will return to
Active
if the
Primary DLCI goes down again before the timer expires.)

a pre-determined number of transmissions of the switchover/switchback
command. Any received or held traffic will be discarded.
