Field	Description
	G.703 Port
Errored Seconds (ES)	The number of one-second intervals in which at least one bipolar violation (BPV) or one CRC-4
24 Hour Count	error was detected at the G.703 input port during the last 24hours.
Severely Errored Seconds (SES)	The number of one second intervals during which a Loss of Signal (LOS), an Alarm Indication
24 Hour Count	Signal (AIS), or a Loss of Frame (or CRC-4 Multiframe) Alignment (LFA) occurred at the incoming
	port.
Unavailable Seconds (UAS)	The number of seconds that G.703 input signals were unavailable during the last 24 hours. After
24 Hour Count	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.
CRC Errored Seconds	The number of CRC-4 errors that were detected at the G.703 port since error counters were last
(Cumulative)	cleared. Turning CRC-4 mode on (ENA) and off (DIS) clears the CRC-4 error counter.
Bipolar Violation Seconds	The number of seconds in which bipolar violations were detected at the G.703 port since error
(Cumulative)	counters were last cleared.
Clear 24-Hour History	The date and time that the 24-hour histories were last cleared are displayed here. Enable this
	function by pressing L or ENTER to clear all 24-hour history counters (including HDSL). This
	action must be confirmed by pressing Y .
