Support dual-fiber bidirectional application with 8 effective optical interfaces.
Provide a subcard bypass control button. Press the button to enable the bypass protection.
Release the button to return to the MCC control.
When the button is pressed down, the iTN201-R supports power failure bypass
protection, which means that the subcard works in the master link if the iTN201-R runs
normally and the subcard switches to the bypass link if the device fails.
When the button is released, the iTN201-R supports the MCC control, which controls in
which state (master or bypass) the subcard works.
Support hot swapping.
