This attribute indicates whether the Aps component is experiencing
an APS mode mismatch alarm (code 7011 5272). This alarm
indicates either:
(1) that the far end is operating with a 1:n switching architecture
(not supported by Passport), as opposed to 1+1; or
(2) that the far end's provisioned mode is not the same as the nears
end's provisioned mode.
When a mode mismatch occurs: (1) if the far end is operating with a
1:n switching architecture it will operate as 1+1; and (2) if either
end has a provisioned mode of unidirectional then both ends will
operate unidirectionally.
