Viewing DSX-1 Performance Statistics
DSX-1 performance statistics allow you to monitor the current status of the DSX-1
interface operations when ESF framing is selected. 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).
To view the Network Performance Statistics, follow this menu selection sequence:

DSX-1 Performance Statistics are collected for:
H ES (Errored Seconds): Seconds during which one or more error events
occurred.
H 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.
H SES (Severely Errored Seconds): Seconds during which 320 or more cyclic
redundancy check (CRC) error events or at least one Out of Frame (OOF)
event occurred.
H 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 320 CRC errors.
H CSS (Controlled Slip Seconds): Seconds during which one or more
controlled slips (as defined in TR 54016) occurred.
