Total Access 600 Series System Manual Section 4 User Interface Guide

INTERFACES (T1) > STATUS > PERFORMANCE > CURRENT AND TOTALS > SES

SES (Severely Errored Second) - For ESF mode, an SES is a second with 320 or more PCVs, or one or more OOF defects, or a detected AIS defect. For D4 (SF) mode, an SES is a second with one or more Framing Error events, or an OOF defect, or at least 1544 Line Code Violations or more.

INTERFACES (T1) > STATUS > PERFORMANCE > CURRENT AND TOTALS > SEF

SEF (Severely Errored Frame) - An SEF condition occurs when 2 out of 6 consecutive frame bits are in error.

INTERFACES (T1) > STATUS > PERFORMANCE > CURRENT AND TOTALS > FS

FS (Frame Slip) - A frame slip is defined as one or more frame bit errors in a one-second interval.

INTERFACES (T1) > STATUS > PERFORMANCE > CURRENT AND TOTALS > LCV

LCV (Line Code Violation) - A Line Code Violation is defined as a Bipolar Violation (BPV), not including the B8ZS code word if B8ZS is employed. The number displayed is LCV events, which is defined as one or more BPVs in a one-second interval.

INTERFACES (T1) > STATUS > PERFORMANCE > CURRENT AND TOTALS > SLP

SLP (Slip Error Event) - This occurs when a received frame is either repeated or deleted. A SLP error indicates a timing problem.

INTERFACES (T1) > STATUS > PERFORMANCE > CURRENT AND TOTALS > UAS

UAS (Unavailable Seconds) - When 10 consecutive SESs have been logged, the unit is declared in an unavailable state, the 10 SESs are cleared, and the Unavailable Seconds count begins to increment starting with 10. The unavailable state is cleared when 10 consecutive non-SES seconds have occurred.

INTERFACES (T1) > STATUS > PERFORMANCE > EXTENDED

Provides statistics for the last 24 hours (in 15 minute windows) on key performance measures as specified in ANSI T1.403 and AT&T TR 54016 for each of the T1 ports. Refer to the CURRENT AND TOTALS performance information for more details on listed statistics.

INTERFACES (T1) > STATUS > PERFORMANCE > CLEAR CURRENT DATA Clears all statistics collected in the CURRENT AND TOTALS statistics table.

INTERFACES (T1) > STATUS > PERFORMANCE > CLEAR ALL DATA

Clears all statistics collected in the CURRENT AND TOTALS and the EXTENDED 24 hour statistics tables.

INTERFACES (T1) > STATUS > ALARMS

Displays current alarms and alarm history for T1 interface.
