Information in Monitor LTU and NTU Interface Screens
Field
Description
LTU Interface (G.703 Port)
Errored Seconds
(ES) 24 Hour
Count
The number of one-second intervals in which at least one bipolar
violation (BPV) or one CRC-4 error was detected at the G.703 input
port during the last 24 hours.
Severely Errored
Seconds (SES)
24 Hour Count
The number of one-second intervals during which a Loss of Signal
(LOS), an Alarm Indication Signal (AIS), or a Loss of Frame (or CRC-4
Multiframe) Alignment (LFA) occurs at the incoming port.
Unavailable
Seconds (UAS)
24 Hour Count
The number of seconds that G.703 input signals were unavailable
during the last 24 hours. After ten consecutive SESs, the system is
deemed unavailable, and the current UAS counter begins counting
from ten. After ten consecutive non-SESs, the system returns to
availability, and the ten counts representing the non-SESs are
removed from the UAS counter.
Bipolar Violation
Seconds
(Cumulative)
The number of seconds in which bipolar violations are detected at the
G.703 port since error counters were last cleared.
Clear 24-Hour
History

Ctrl Signal State
Displays the status of the control signals at the Nx64K port at
one-second intervals. ON indicates an active line. OFF indicates an
inactive line. Displayed fields are:
