the wavelength has achieved the target output power from the LD pack. Enter the
following commands on both end points to determine if the launch power has been
achieved.

Ensure that the transponder can provide the required power. If the transponder can

provide enough power, clean fiber connectors from the transponder to the OT or SVAC
port to ensure the connections are clean.

OCHPDI
OCHPDI (Channel Payload Defect Indicator)
During the creation of a wavelength add cross connect, the source node of the optical
channel will raise this non reported condition when the output wavelength is not
launching at the correct power or when the optical channel is missing. This condition
clears when the power of the wavelength is launching with the correct power. As the
wavelength traverses the network, subsequent network elements have the Channel FDI
present on the amplifier cards until the power level of the wavelength reaches the target
power. When the target power is reached, the Channel PDI clears automatically within 5
minutes.
Note: This not-reported condition masks other reported optical channel alarms to
effectively suppress alarms and transient alarms during cross connect setup.
