Some alarms, such as the Trace Identifier Mismatch (TIM) alarm, can occur at multiple levels, like the Regenerator Section (RS), Multiplexer Section (MS), and High-order (HO) Path, and Low-order (LO) Path levels. In most cases, alarms are cleared in the same fashion at all levels. NOTE: Layers/levels in this section refer to SDH overhead fame hierarchical levels, such as RS, MS, and HO path, which delineate various segments of the transmission network interconnecting SDH network elements (NEs). These terms are used interchangeably throughout this section.

EMS-XDM alarm types include: |

Transmission: alarms reported by the XDM indicating transmission problems

|

Optical Power Control-related Transmission: transmission alarms related to optical power control reported by the XDM

|

Service: alarms generated by transmission problems at the service layer

|

Timing: timing alarms reported by the XDM

|

Equipment: alarms reported for hardware failures/malfunctions

|

EMS-XDM-specific: alarms internal to the EMS-XDM management system

For transmission alarms and optical power control-related transmission alarms, the technique used to evaluate the level of system performance is to count the number of error events and increment the respective counter each time an event occurs. A PM alarm occurs whenever the threshold value of the event counter is crossed. Thresholds and counters are maintained for 15-minute and 24-hour periods.

Administrative Unit (AU)/Tributary Severity: Major Unit (TU) AIS The AU/TU-AIS indicates that a failure has occurred upstream of the equipment sending the AIS. It indicates that another alarm exists before the equipment sending the AIS. To clear an AU/TU-AIS alarm: 1. Check higher-level alarms on this port. 2. If there are no alarms, go back to previous connections and do the same. The problem could be in any of the NEs before this port.

Degraded (DEG) Severity: Minor The DEG alarm indicates that the Bit Error Rate (BER) on the incoming frame is higher than the configured threshold. This threshold is lower than the one specified for the EXC alarm. To clear a DEG alarm: 1. Check performance at higher levels (RS, MS). 2. Check the input power level on the physical interfaces. 3. Check the path (MS/VC) optics and PM data. 4. If the alarm appears in AU/TU objects, the problem may have appeared before this NE. In this case, check and clean the fiber optic connector (if it is an electrical connector, it should be firmly connected). 5. If instructed to do so by qualified ECI Telecom personnel, replace the faulty card.

Loss of Alignment (LOA) Severity: Major The LOA alarm indicates a loss of alignment on the incoming concatenation signal (that is, the VC-4 has exceeded its allocated RAM for delay compensation). To clear an LOA alarm: |

Verify that the difference between the fast VC-4 and the slow VC-4 in the same VC-4 group does not exceed the allocated RAM. To do this, examine the network topology and search for a path for the concatenation signal in which the total distance between nodes is less than the maximum permissible delay compensation.

Loss of Data (LOD) Severity: Major The LOD alarm indicates that the optical LOS is not detected and no signal transitions exist. This alarm applies only to OPS objects on TRP and SIO64F cards. LOD alarms may result when: |

The received frequency does not match the expected frequency.

|

The received protocol does not match the expected protocol.

|

The received signal does not include FEC in the optical layer, but FEC was expected.

To clear an LOD alarm: |

Verify that the data flow rate is correct within the link.

Loss of Frame (LOF) Severity: Major The LOF alarm indicates that no frame alignment was detected in the incoming signal. The far end of the link can cause this alarm. This is a major alarm condition, as the receiver cannot recognize any data from the fibers. This alarm is detected at the RS level. Both failures at the source (transmitter) and extremely high BER conditions can generate LOF alarms. High BER conditions can be caused by problems such as: |

Extremely high received optical power levels

|

Very low received optical power levels

|

A receiver malfunction or a problem with the other-side transmitter

In addition, an LOF alarm can be caused by an incorrect rate, which typically only occurs during installation. The LOF alarm is triggered when severely errored framing (SEF) persists for three or more milliseconds. When troubleshooting an LOF alarm, it is critical to have a full understanding of the root cause of the LOF defect before attempting to correct the problem. If an LOF alarm occurs during installation, it is likely that optical planning was incorrect. An LOF alarm may also occur after some maintenance operations, as it is not unusual to obtain higher power levels after maintenance has been performed. To clear an LOF alarm: 1. Check for BIT alarms on both sides of the link. 2. If instructed to do so by qualified ECI Telecom personnel, replace the faulty card.

Loss of Multiframe (LOM) Severity: Major The LOM alarm indicates a loss of multiframe alignment on the incoming signal. This alarm is triggered when a loss of synchronization is detected on byte H4 (bit 7, 8) in a superframe sequence. This alarm can result from: |

A faulty card

|

Connected test equipment that does not support multiframe

To clear an LOM alarm: |

If instructed to do so by ECI Telecom personnel, replace the faulty card.

Loss of Multiframe - Concatenated (LOMC) Severity: Major The LOMC alarm indicates a loss of multiframe alignment related to concatenated trails. To clear an LOMC alarm: |

Verify that the cross-connected VC-4 source is a member of the concatenated group.

Loss of Pointer (LOP) Severity: Major The LOP alarm indicates that invalid pointers were received due to an equipment failure, mismatch in signal mapping, or timing problem. To clear an LOP alarm: 1. Search for system timing alarms to determine the origin of the LOP alarm. 2. If instructed to do so by ECI Telecom personnel, replace the faulty card.

Sequence Mismatch (SQM) Severity: Major The SQM alarm indicates a loss of sequence on the virtual concatenation signal. This error may be caused by a mismatch in connections. For example, in the XC Browser, check the XC set for each NE along the path to ensure that the concatenation group objects are connected in the same order along the entire path. Access the XC Set List window to perform this check. NOTE: DIO and EIS/EISM cards use a transparent reordering process to modify incorrect sequencing of virtual containers in the group. Therefore, the SQM alarm will be reported only when two or more members from the same virtual concatenation group have the same sequence number. To clear an SQM alarm: |

Verify that all VC-4s in the virtual concatenation group are connected in the same order along the path.

Server Signal Fail (SSF) Severity: Major The SSF alarm indicates a failure in the adaptation function due to an AU-AIS or AU-LOP.

Trace Identifier Mismatch (TIM) Severity: Major The TIM alarm indicates a trace identifier mismatch caused by the incorrect provisioning of the expected trace or a misconnection. This alarm results from comparing the expected J0/J1/J2 byte to the received one. To clear a TIM alarm: 1. If the link is between a unit and an XDM NE, open the EMS-XDM Alarm Severity window, deselect TIM Detection, and select TIM Inhibition. 2. Adapt the Trace ID label to the label actually received. 3. Check PM counters. If they show errors, check the cause, for example, timing in higher levels.

TCAs PM thresholds of an object are determined by the assigned PM profile. The PM profile contains a threshold setting for each PM counter relevant to the object type. Threshold-crossing alarms (TCAs) are triggered when the PM threshold for an object is exceeded. There are two thresholds for each PM interval (15-minutes and one day): a low threshold and a high threshold. When the value of a PM counter is higher than the high threshold, an alarm is reported. PM profiles are user-defined and can be used by the operator to troubleshoot alarms. For example, if the current high threshold settings within a PM profile are relatively low, you can change these settings to determine if an alarm, such as an Errored Seconds alarm, resulted from a sudden bursty error or errors that have accumulated over time. By changing the threshold setting in the PM profile, you can detect if the error was received over a long or short period of time. The following topics describe the XDM TCAs.

Background Block Errors Far End (BBEFE) Severity: Warning The BBEFE alarm is a threshold-crossing alarm that indicates that the system crossed the one day or 15 minute background block errors threshold at the far end. Since the BBEFE alarm is often reported at multiple levels, you should begin the alarm resolution process by checking for the alarm at multiple levels and then looking for a common denominator for the problem. Frequently, one card can cause several paths to report errors. To clear a BBEFE alarm: 1. If the alarm is reported at the low-order level, check the other ports on the same card to rule out the possibility of a hardware failure. 2. If it is reported at the high-order level as well, check the optical parameters, clean the fiber optic connectors, and then monitor performance at the highorder level.

Client Signal Fail (CSF) Severity: Warning The CSF alarm indicates a fault that exists on the far-end (upstream) client side. The alarm is generated upon detection of loss on the link from the client (OPI Snk object). By default, this alarm is not reported. Upon detection, the OPI laser is shut down. This alarm is useful in cases where the client supports some Ethernet protection scheme that may be operated in case of a far-end client failure, assuming that the underlying layer is okay. In cases where GbE connections are implemented over a transport network (such as by the DIO), the client may not sense a failure that occurred in the transport network or in the far-end GbE link. The CSF alarm provides the necessary client notification mechanism should such conditions occur. To clear a CSF alarm: 1. Check the link between the far-end DIO and the far-end client. 2.

Optical Power Control-related Transmission Alarms Optical power control-related transmission alarms apply to all SDH levels, unless otherwise noted. The following topics describe the XDM optical power control-related transmission alarms.

Gain Input Overloaded Severity: Major The Gain Input Overloaded alarm indicates a gain input overload condition in an OFA-2 card. This alarm occurs when the power budget in the link is poorly planned, resulting in elevated input power levels to the optical amplifier and amplifier gain that is too high. These factors cause low attenuation between the input of the card and the input of the gain block, meaning that the optical power at the input of the gain block is higher than the permitted level, causing overload. To clear a Gain Input Overloaded alarm: 1. Check the optical parameters to determine if they are within the required ranges. 2. Recalculate the link power budget parameters, adjust the system based on your revised calculations, and then recalibrate.

Illegal Alarm Severity: Major The Illegal alarm indicates that the required correction is beyond the gain capability of the card, and that the set correction is less than the required correction. To clear an Illegal alarm: |

11-38

Since the required correction is greater than the remaining capability of the card, replace the card with one that has a higher gain capability.

Input Power Change Severity: Major The Input Power Change alarm indicates that the required correction is greater than the Low Alarm Threshold that was added. This alarm can result from conditions that are temporary and reversible or conditions that are permanent. For example: |

A fiber cut that has been spliced to repair the cut: In this case, the fiber splice produces attenuation at the site of the splice. This is usually a permanent condition that must be corrected to prevent the generation of an Input Power Change alarm.

|

Bending of fibers while performing fiber maintenance: This is typically a temporary condition. The Input Power Change alarm usually disappears when the fibers are straightened out.

To clear an Input Power Change alarm: 1. Check the line for changes or abnormal attenuation. 2. Determine if the present situation is a temporary or permanent condition. If the alarm resulted from a permanent condition (see previous explanation), make the following change: In the EMS-XDM Power Control window, access the Gain Control window. In this window, select Adopt (Changes) and then click Apply.

Set Capability Exceeded Severity: Major The Set Capability Exceeded alarm indicates that the required correction is beyond the gain capability of the card, and that the set correction is less than the required correction. NOTE: This alarm serves as a warning to the operator that the current power budget margins are insufficient and will not be able to continue to provide the compensation required. Therefore, you should consider replacing the card with one that has a higher gain capability. Even if traffic is still flowing without errors, the next time an Input Power Change alarm occurs in the same direction (up or down), the card with the Set Capability Exceeded alarm may not be able to compensate for the gain.

To clear a Set Capability Exceeded alarm: |

Replace the card with one that has a higher gain capability, since the required correction is greater than the remaining capability of the card. For example, if the current OFA card has a 23 dB gain, replace it with one that has a 29 dB gain.

Tracking Limit Exceeded Severity: Major The Tracking Limit Exceeded alarm indicates that the span attenuation changes more than the power control can correct. This alarm usually occurs as a result of some type of catastrophic event, such as an NE shutting down unexpectedly or a fiber cut, and is typically accompanied by other alarms such as LOS. To clear a Tracking Limit Exceeded alarm: 1. Investigate possible events that may have caused the abnormal attenuation, such as an NE shutdown or a fiber cut. 2. Take relevant measurements that may aid in identifying the reason for abnormal attenuation. 3. Check the span attenuation and correct it. 4. If you fail to clear the alarm, reconfigure the power control definitions. Because this alarm rarely results from actual power control-related problems, you should perform this step only when all other avenues fail to resolve the alarm.

Check the optical parameter levels to ensure they are within the correct ranges. 4. Clean the fiber connectors.

Service Degraded Severity: Major The Service Degraded alarm indicates degradation in the traffic signal. This alarm may also indicate that a XC that is part of a trail is transmitting traffic, but the traffic is recognized as degraded. If the service is on an unprotected path, this alarm indicates a degraded traffic signal somewhere along the path. If the service is on a protected path, then it indicates one of two possible problems: either the nonactive path has failed, or the service on the active path is degraded. To clear a Service Degraded alarm: 1. Check information and performance for all object types that are part of the protection path. 2. Check for a failure on the nonactive path. 3. Open masking on relevant objects to try to locate the origin of the problem. 4. If the alarm is reported at the low-order level, check the other ports on the same card to rule out the possibility of a hardware failure. 5.
