The revertive mode of the APS group.
nonrevertive
Traffic remains on the protection line until another
switch request is received.
revertive
When the condition that caused a switch to the
protection line has been cleared the signal is switched
back to the working line. Since switching is revertive
with the 1:n architecture, cApsConfigRevert must
be set to revertive if cApsConfigMode is set
to oneToN.
Switching may optionally be revertive with the 1+1
architecture.
This object may not be modified if the associated
cApsConfigRowStatus object is equal to active(1).
