[CAUSE] The tmnxOesOptTrnspndrMiscFail notification is generated when a non-service affecting hardware defect is detected on the card. This condition may be declared on the card due to one of the following causes: 1) Detection of line side transmitter laser bias or optical output power nearing end-of-life. 2) Detection of line receiver ITLA (Integrated Tunable Laser Assembly) laser bias or output power nearing end-of-life. 3) Detection of board-level Analog-to-Digital Conversion Digital Signal Processor (ADC DSP) device defect. 4) A device-to-device interface communication problem. [EFFECT] The tmnxOesOptTrnspndrMiscFail alarm indicates a lower priority fault on the card that does not directly affect the traffic currently flowing through the card. However, the card should be replaced at the next available maintenance opportunity. [RECOVERY] Replace the card.
