Command Description
C 24 hour LCV—Line Code Violation: Displays the 24 hour NE LCV performance data register,
Figure 3-11.
E 24 hour LES—Line Errored Seconds: Displays the 24 hour NE LES performance data register.
S 24 hour LSES—Line Severely Errored Seconds: Displays the 24 hour NE LSES performance
data register in 96 15-minute intervals.
V 24 hour P-bit CV—P-bit Code Violation: Displays the 24 hour NE P-bit CV performance data
register.
R 24 hour P-bit CV ES—P-bit Code Violation Errored Seconds: Displays the 24 hour NE P-bit CV
ES performance data register.
M 24 hour P-bit CV SES—P-bit Code Violation Severely Errored Seconds: Displays the 24 hour
NE P-bit CV SES performance data register.
P 24 hour C-bit CV—C-bit Code Violation: Displays the 24 hour NE C-bit CV performance data
register.
B 24 hour C-bit CV ES—C-bit Code Violation Errored Seconds: Displays the 24 hour NE C-bit
CV ES performance data register.
I 24 hour C-bit CV SES—C-bit Code Violation Severely Errored Seconds: Displays the 24 hour
NE C-bit CV SES performance data register.
F 24 hour SEFS—Severely Errored Framing Seconds: Displays the 24 hour NE SEFS
performance data register. Severely Errored Framing Seconds are those seconds in which
two or more framing bit errors occur within a 3-millisecond period. For ESF, this interval
may or may not coincide with an ESF (i.e., six framing bits).
A 24 hour AISS—Alarm Indication Signal Seconds: Displays the 24 hour NE AISS performance
data register.
U 24 hour UAS—Unavailable Seconds: Displays the 24 hour NE UAS performance data register.
An Unavailable Second is counted for every second in which an Unavailable Signal State
occurs (This term is used by new standards in place of Failed Seconds). The Unavailable
Signal State is declared whenever 10 consecutive Severely Errored Seconds (SES) occur. The
Unavailable Signal State will not clear until 10 consecutive seconds of data are processed
with no SES present.
L 24 hour LOSS—Loss of Signal Seconds: Displays the 24 hour NE LOSS performance data
register. A Loss of Signal is the state of a network line when no bits are detected on input to
the receiving equipment. The time for detection of Loss of Signal will vary depending on the
type of equipment used. A Loss of Signal Second is a second during which the equipment
detects no signal.
O 24 hour LOFS—Loss of Frame Seconds: Displays the 24 hour NE LOFS performance data
register. A Loss of Frame occurs when the framing bit of the data packet is not detected by
the receiving equipment. A Loss of Frame Second is a second during which the equipment
can not detect the framing bit of the data packet.
