DESCRIPTION

Down/Up Stream	The number of Blocks transmitted (downstream) or received (upstream) on this
BLKS	ADSL port. A block is a set of consecutive bits associated with the path; each bit
	belongs to one and only one block. Consecutive bits may not be contiguous in
	time.
Down/Up Stream	The Number of Errored Seconds transmitted (downstream) or received (upstream)
ES	on this ADSL port.
Down/Up Stream	The Number of Severely Errored Seconds transmitted (downstream) or received
SES	(upstream) on this ADSL port. Severely errored seconds contained 30% or more
	errored blocks or at least one defect. This is a subset of the Down/Up Stream ES.
Down/Up Stream	The downstream or upstream number of UnAvailable Seconds.
UAS
Fast FEBE	In fast mode, the number of Far End Block Errors.
Fast NEBE	In fast mode, the number of Near End Block Errors.
Fast FEFEC	In fast mode, the number of Far End Forward Error Count.
Fast NEFEC	In fast mode, the number of Near End Forward Error Count.
Interleaved FEBE	In interleaved mode, the number of Far End Block Errors.
Interleaved NEBE	In interleaved mode, the number of Near End Block Errors.
Interleaved	In interleaved mode, the number of Far End Forward Error Count.
FEFEC
Interleaved	In interleaved mode, the number of Near End Forward Error Count.
NEFEC
LPR	This is the number of times that the subscriber’s ADSL device has experienced
	a Loss of PoweR (been off).
15 min, 1day history	This section of the screen displays line performance statistics for the current and
	previous 15-minute periods, as well as for the current and previous 24 hours.
ATUC	These statistics are for the connection (or traffic) coming from the subscriber’s
	device to the AAM.
ATUR	These statistics are for the connection (or traffic) going from the AAM to the
	subscriber’s device.
lofs	The number of Loss Of Frame Seconds that have occurred within the period.
loss	The number of Loss Of Signal Seconds that have occurred within the period.
lols	The number of Loss Of Link seconds that have occurred within the period.
lprs	The number of loss of PoweR Seconds that have occurred within the period.
eSs	The number of Errored SecondS that have occurred within the period.
inits	The number of initialization failure traps that have occurred within the period.
sesl	The number of Severely Errored Seconds that have occurred within the period.
uasl	The number of UnAvailable Seconds that have occurred within the period.
