    134 Correct ROADM operation requires Line In port of a ROADM to always receive a light. That is why there is a dedicated transceiver (tengigabitethernet 1/33/1 on ToR) that sends light through all ROADMs by passing through loop-back connection on Calient S320 (port 5.5.1) and redirecting back, so the light is received on the same transceiver.
