SYNC L SEC (Out-of-Synchronization Seconds) — The number of seconds during which the receiver has lost pattern synchronization, even momentarily, since initial DS1 pattern synchronization. AVAIL SEC (Available Seconds) — A count of seconds with no errors since initial pattern synchronization. %AVAIL SEC (Percent Available Seconds) — The ratio of available seconds to total seconds since test start. SEV ERR SEC (Severely Errored Seconds) — The number of seconds with a BER worse than 10-3. %SEVERR SEC (Percent Severely Errored Seconds) — The ratio, expressed as a percentage, of severely errored seconds to the number of available seconds. CSES (Consecutive Severely Errored Seconds) — A count of groups of three or more contiguous SES. DEG MIN (Degraded Minutes) — The number of minutes with a BER worse than 10-6. %DEG MIN (Percent Degraded Minutes) — The ratio of degraded minutes to total available minutes. UNAVAIL SEC (Unavailable Seconds) — The number of unavailable seconds since the test started. 4.3.3 BPV/FRM Category The DS1 BPV/FRM (BPV & FRAME) category test results are defined as follows: VIOLATIONS (Bipolar Violations) — The number of bipolar violations (BPVs) detected.
