Monitoring the Unit6-4 7914-A2-GB20-00February 1998For example, pressing 1 at the stats prompt yields a screen like the following:stats→ 1Current 1 minute:SDSL Errors: T1 Errors:FAW – 0 BPV – 0CRC – 0 MOS – 0FEBE – 0 FAS – 0(D4 framing only)CRC – 0(ESF framing only)Previous 1 minute:SDSL Errors: T1 Errors:FAW – 0 BPV – 0CRC – 0 MOS – 0FEBE – 0 FAS – 0(D4 framing only)CRC – 0(ESF framing only)stats→ Performance statistics have a maximum value of 65,536. If the maximumvalue is reached, the statistic resets to zero. Performance statistics are updated every second. T1 Errors (BPV, MOS, FAS, and CRC) are only displayed forDSX-1-compatible units that are operating in framed mode.Interface Counter MeaningSDSL FAW Frame Alignment Word. Loss of synchronizationwas detected.CRC Cyclic Redundancy Check. An invalid CRC valuewas detected.FEBE Far End Bit Error. An error was reported by theremote equipment.T1 BPV Bipolar Violation. Two consecutive pulses of thesame poalrity were detected.MOS Multiframe Out of Sync. Loss of synchronizationwas detected.FAS Frame Alignment Signal. A loss of signal wasdetected. (Shown only when Framing is set to D4.)CRC Cyclic Redundancy Check. An invalid CRC valuewas detected. (Shown only when Framing is set toESF.)
