FALM: Frame Alarm seconds is a count of seconds that have had
far end frame alarm (FAS Remote Alarm Indication, RAI) since
the start of the test.
FE: Count of the number of Frame bit Errors since the start of the
test. N/A is displayed when the test set has not synchronized on
a known framing pattern within the received signal.
Hz/PPM: The Hertz/Part Per Million count records any variance
from 2.048 Mbit/s in the received frequency.
LOFS: Loss Of Frame Seconds is a count of seconds since the
start of the test that have experienced a loss of frame.
LOSS: Loss Of Signal Seconds is a count of the number of sec-
onds during which the signal has been lost during the test.
+LVL, -LVL: Positive and Negative Level is the level of positive
and Negative pulses received by the test set displayed in decibels
variance from G.703 specified level (dB).
Lpp: Level Peak-to-Peak is the peak-to-peak level of negative
and positive pulses being received by the test set displayed in
decibels variance from DSX level (dB).
MAX Hz, MIN Hz: Maximum and Minimum frequencies since
the start of the test.
MFAL: Multiframe Alarm seconds is a count of seconds that have
had far end multiframe alarm (MFAS Remote Alarm Indication,
RAI) since the start of the test.
RxCLK: Received clocking frequency.
+/- RxLVL: Positive or negative level of pulses received.
RCV Hz: Frequency measured during the last second.
SES: Count of Severely Errored Seconds since the start of the
-3
test. A severely errored second has an error rate of >10 . SES
is not counted during unavailable time.
%SES: Percentage of seconds since the start of the test that are
Severely Errored Seconds.
SLIP: Count of Bit Slips that occur when the synchronized pattern
either loses a bit or has an extra bit stuffed into it.
UAS: Count of Unavailable Seconds that have occurred since the
start of the test. This begins at the onset of 10 consecutive SES.
The displayed value of UAS updates after the tenth consecutive
severely errored second occurs. It also begins at LOS or LOF.
%UAS: Percentage of Unavailable Seconds since the start of
the test.
