			T	S
ES-L (b)	Errored Seconds - Line	UAS-P	Unavailable Seconds - Path
	Seconds with BPV ≥ 1.		A second of unavailability based on SES-P or AIS

SES-L	Severely Errored Seconds - Line	PRM-NE (c)	Performance Report Messaging - Near End
	Seconds with BPV plus EXZ ≥ 1544.		The PRM from CPE indicates errors, and the

UAS-L	Unavailable Seconds - Line	PRM-FE (c)	Performance Report Messaging - Far End
	Seconds with LOS ≥ 1.		The PRM from the network indicates errors, and
			the signal received from the CPE is error-free.
CV-P	Code Violation - Path	B8ZSS (d)	B8ZS Monitored Seconds
	Total count of SF frame bit (FB) errors or ESF,		Seconds with B8ZS detection when AMI option

ES-P (e)	Errored Seconds - Path	MSEC (d)	Monitored Seconds of the current (15 minute/1
	Seconds with SEF (f), CRC (ESF) or		hour/1 day) screen.
	FE (b)(SF) ≥ 1.

(a)FE is a frame bit error.

(b)Line refers to the AMI, DS1 line code used to transport the payload.

(c)Only appears on H2TU-R Performance History screens.

(d)Appears on the DS1 Current Statistics screens.

(e)Path refers to the total framed payload being transported between two points.

(f)Severely Errored Frame— Two or more frame bit errors occurring in a 0.75 ms interval for SF or a 3 ms interval for ESF.
