		Table E-21. E1/T1 Statistics Parameters

Alarm	Failure	Comments

LOS	Loss of Signal	Sync LED Off
		• For T1: A second during which 192 contiguous pulse positions have no
		pulse of either positive or negative polarity (signal is more than 30 dB
		below nominal amplitude.
		• For E1: A second during which 255 contiguous pulse positions have no
		pulse of either positive or negative polarity.

LOF	Loss of Frame	Sync LED Off
		• For E1/T1: A second during which an OOF (see below) error persists for
		2.5 seconds and no AIS error (see below) is detected.

LCV	Line Code	Line Code Violation
	Violation	• For T1: A second during which BPV (Bipolar Violation) or EXZ errors have

		occurred.
		• For E1: A second during which two consecutive BPVs of the same polarity
