What is nms553LedStatus?

A three-octet bitwise snapshot of the unit's front-panel LED states and switches, covering indicators such as ON, DSX1, NMSRSP, NMSDAT, ER, DSX OOF/LOS, NET OOF/LOS/BPV/AIS, TM/ALM, LBK, and per-channel (A/B/C) send/receive data activity. It lets a remote manager see, in one poll, what the unit's front panel would currently be displaying.
