Performance Registers

Register	Interval Description	Totals Description
Event	Error events counter. An error event is a frame	N/A
	with either a Cyclic Redundancy Check (CRC)
	error or an Out Of Frame (OOF) event. The
	maximum count is 65,535. This register is only
	reset as a result of a Clear Performance
	Register command. This register is valid for the
	current interval only.
CurTimer	Current interval timer. This register records the	N/A
	number of seconds in the current 15-minute
	interval. The maximum is 900 seconds. This
	register is valid for the current interval only.
VldIntvl	N/A	Valid interval total. Records the number of valid
		15-minute intervals in the previous x hours, where x
		is 24 hours for aggregate performance and 8 hours
		for port performance. This register is not valid for the
		current interval.
ES	The number of errored seconds for the current	The total number of errored seconds for the previous
	interval. An errored second is any second with	x hours, where x is 24 hours for aggregate
	one or more of the following: errored frame	performance and 8 hours for port performance.
	alignment, CRC error, Loss of Signal (LOS),
	Alarm Indication Signal (AIS), or Loss of Frame
	(LOF). The maximum is 900 seconds.
UAS	The number of unavailable seconds for the	The total number of unavailable seconds for the
	current interval. An unavailable second is any	previous x hours, where x is 24 hours for aggregate
	one second interval when service is	performance and 8 hours for port performance.
	unavailable. The maximum is 900 seconds.	(Detection occurs with 10 consecutive unavailable
		seconds.)
SES	The number of severely errored seconds for the	The total number of severely errored seconds for the
	current interval. For E1 or DTE registers, a	previous x hours, where x is 24 hours for aggregate
	severely errored second is any second with 805	performance and 8 hours for port performance.
	or more CRC errors, 16 or more errored frame
	alignment signal events, or one or more LOS,
	AIS, or OOF event. For port registers, a
	severely errored second is any second with 320
	or more CRC errors, or one or more OOF
	event. The maximum is 900 seconds.
BES	The number of bursty errored seconds for the	The total number of bursty errored seconds for the
	current interval. For E1 or DTE registers, a	previous x hours, where x is 24 hours for aggregate
	bursty errored second is any second with more	performance and 8 hours for port performance.
	than one, but less than 805, CRC errors when
	in CRC4 mode, or more than one, but less than
	16, errored frame alignment signals when in
	non-CRC4 mode. For port registers, a bursty
	errored second is any second with more than
	one, but less that 320, CRC errors. The
	maximum is 900 seconds.
