Configuration of alarm information for incorrect optical fiber connections on WDM products

On OTN devices, the OTS-layer TTI bytes can be set on FIU boards to support incorrect connection detection for an OTS section. When incorrect connections are detected, OSC boards report alarms. This function is disabled by default. You can manually enable the function and set the TTI bytes.

1. Enable the OTS_TIM alarm monitoring function.
2. Configure the TTI bytes on both ends of the OTS section. When the OTS optical fiber connection is abnormal, the OTS_TIM alarm will be reported.
