Enable Look-In Mode
T-APS-R units will do a checking function to the CPE signal before switching from active path to
the protection path.
Enable: T-APS-R will be enabled to check CPE signals. In the event of excessive bit
errors from the CPE side to T-APS-R, T-APS-R will not perform switching. Enable
Look-In may increase a few mili-second to the switching time.
Disable: T-APS-R will be disabled to check CPE signals. In the event of excessive bit
errors from the CPE to T-APS-R, T-APS-R will perform switching in all events
including excessive bit errors from CPE side
