2.3.1 Chromadigm Chirp Cancelled Transmitter Module CCTX (CCT4/CCT2)
The Chromadigm Chirp Cancelled Transmitter Module CCTX (CCT4/CCT2) has four pairs of LEDs on the front panel
marked with their associated ITU channel 1 to 4.
The CCTX detects the alarms and reflects them on the front panel LEDs based on the following schema.

Example #1: The module temperature is normal, but the laser temperature is at a level that indicates a major alarm. The top
LED associated with the interface shall be observed as “red”.
2.3.2 Chromadigm Chirp Cancelled Transmitter Module (CCT1)
The Chromadigm Chirp Cancelled Transmitter Module (CCT1) and CCT1 variance have one pairs of LEDs on the front
panel marked with their associated ITU channel 1.
The CCT1 detects the alarms and reflects them on the front panel LEDs based on the following schema.
