Red alarm light (red)					Indicates loss of local E1 frame alignment, or it indicates loss of packet
					alignment on the NTM.

Yellow alarm light (yellow)					Indicates loss of frame alignment at remote end or loss of packet alignment
					(NTM).

AIS light (green)					Indicates the presence of all ones on the line.
