Viewing G.703 Performance Statistics (Model 7996)
G.703 performance statistics allow you to monitor the current status of the G.703
interface operations. Performance statistics can assist you in determining the
duration of specific conditions and provide a historical context for problem
detection and analysis. Statistics are maintained for up to 96 15-minute intervals
(24 hours).

→Status→Performance Statistics→G.703 Performance Statistics
Select PgUp or PgDn to view the next or previous seven intervals.
Select ClrStats to clear all statistics to zero.
G.703 Performance Statistics are collected for:
ES (Errored Seconds): Seconds during which one or more CRC errors has
occurred (as defined in G.826, section 4.1.1). Maximum value is 900.
occurred (as defined in G.826, section 4.1.1). Maximum value is 900.
UAS (Unavailable Seconds): Seconds during which service is unavailable.
UAS is received at the start of 10 consecutive SES and cleared at the start of
10 seconds with no SES. Maximum value is 900.
UAS is received at the start of 10 consecutive SES and cleared at the start of
10 seconds with no SES. Maximum value is 900.
SES (Severely Errored Seconds): Seconds during which 805 or more CRC
errors, more than 16 Frame Alignment Signal (FAS) errors, or at least one
Loss of Signal (LOS) or Alarm Indication Signal (AIS) has occurred. Maximum
value is 900.

Loss of Signal (LOS) or Alarm Indication Signal (AIS) has occurred. Maximum
value is 900.
BES (Bursty Errored Seconds): Contains the number of bursty errored
seconds for the current interval. A bursty errored second is any second with
more than one but less than 805 CRC errors (CRC Mode) or more than one
but less than 16 FAS errors (non-CRC mode). Maximum value is 900.
