在广域网,光纤SDH/SoNET 网络排错中经常会看到很多缩写。

这里大概总结了下,常用的参数缩写,供大家参考。

 

SDH error and alarm signals

In SDH overhead, there are a lot of OAM functionalities inter alia used for signaling errors over the transport network.
Here’s an short overview for important signals supported by Cisco.

  • Regenerator Section Errors and Alarms
    LOS regenerator section alarm indication signal
    LOF regenerator section loss of frame
    RS-TIM regenerator section trace identifier mismatch
    RS-BIP regenerator section bit errors (BIP parity error)
  • Multiplex Section Errors and Alarms
    MS-AIS multiplex section alarm indication signal
    MS-REI multiplex section path remote error indicator
    MS-RDI multiplex section path remote defect indicator
    MS-BIP multiplex section bit errors (BIP parity error)
  • Higher-order Path Errors and Alarms
    HP-UNEQ higher-order path unequipped
    HP-TIM higher-order path trace identifier mismatch
    HP-BIP higher-order path bit errors
    HP-REI higher-order path remote error indicator
    HP-RDI higher-order path remote defect indicator
    HP-PLM higher-order path payload label mismatch
  • Lower-order Path Errors and Alarms
    TU-LOP tributary unit loss of pointer
    TU-NDP tributary unit new data flag in pointer
    TU-AIS tributary unit alarm indication signal
    TU-LOM tributary unit loss of multiframe
    BIP-2/B3 lower-order path bit errors (BIP parity error)
    LP-UNEQ lower-order path unequipped
    LP-RFI lower-order path remote failure indicator
    LP-REI lower-order path remote error indicator
    LP-RDI lower-order path remote defect indicator
    LP-TIM lower-order path trace identifier mismatch
    LP-PLM lower-order path payload label mismatch
  • Line Errors and Alarms
    AIS-L line alarm indication signal
    REI-L line remote error indicator
    RDI-L line remote defect indicator
    BIP-L line bit errors (BIP parity error)

 

Abbreviations for PMON

To work with performance monitoring counters (PMON), you have to know the abbreviations and the values available in the different hierarchical levels.

  • Regenerator section
    CV Code Violations Number of BIP-n parity violations
    ES Errored seconds At least one second interval during which at least one error occurred.
    SES Severely Errored seconds A one-second interval during which the BER has exceeded 1 in 10 EE-3.
    SEFS Severely Errored Framing Seconds An Severely Errored Framing Second is a second with either one or more OOF defects or a detected AIS defect.

 

  • Multiplex section, higher-order and lower-order (tributary) path
    CV Code Violations Number of BIP-n parity violations
    ES Errored seconds At least one second interval during which at least one error occurred.
    SES Severely Errored seconds A one-second interval during which the BER has exceeded 1 in 10 EE-3.
    AUAS Unavailable seconds The number of seconds during which the signal is alarmed or experiencing an BER exceeding 1 in 10 EE-3 for 10 consecutive seconds

 

  • Line
    LCV Line Code Violation Indicates the occurrence of either a Bipolar Violation (BPV) or Excessive Zeros (EXZ) error event.
    PCV Path Code Violation Indicates a frame synchronization bit error in the D4 and E1-no CRC formats, or a CRC error in the Extended Superframe (ESF) and E1-CRC formats.
    CSS Controlled slip seconds A Controlled Slip Second is a one-second interval containing one or more controlled slips
    SEFS Severely Errored Framing Seconds An Severely Errored Framing Second is a second with either one or more OOF defects or a detected AIS defect.
    LES Line Errored Seconds Line Errored Seconds (LES) is a second in which one or more Line Code Violation errors are detected.
    DM Degraded minutes A degraded minute is one in which the estimated error rate exceeds 1E-6 but does not exceed 1E-3.
    ES Errored seconds An errored second is a second in which one ore more PCV, CSS or bipolar violation (non-CRC links) is detected
    BES Bursty errored seconds A second with more than one but fewer than 320 Path Coding Violation errors, no Severely Errored Frame defects and no detected incoming AIS defects. Controlled slips are not included in this parameter.
    UAS Unavailable seconds A count of the total number of seconds on the interface. This field is calculated by counting the number of seconds that the interface is unavailable.
    SS Slip seconds Indicates the replication or deletion of the payload bits of a domestic trunk interface (DS1) frame. A slip might happen when there is a difference between the timing of a synchronous receiving terminal and the received signal.
