The fault can be permanent or temporary. The possible causes are as follows: a transmission fault a process or processor restart in this node a faulty ET board a fault in the adjacent signalling node remote and/or field event, not a fault The alarm is issued if the Ethernet switch port is becoming overloaded. The load is 80% or more of the maximum allowed load. The alarm remains as long as the port is overloaded and ceases automatically when the load decreases. If the Ethernet switch port becomes more overloaded, this alarm is replaced by the alarm, Ethernet Switch Port Overload. Causes: Maintenance of Ethernet switches. Fault in the network. Under-dimensioning Faulty link(s) in the node. This alarm appears when the Radio Base Station (RBS) fails to report carrier power and uplink interference measurements to the Radio Network Controller (RNC). Causes: RBS resources are unavailable. An RBS hardware failure prevents it from performing the measurement none remote remote remote rt (SCCP) in the remote node is not accessible from this node. The fault can be permanent or temporary. Normally, the ala Device Disabled remote and/or field An alarm is issued when a user of the Message Transfer Part level 3 (MTP3) in the remote node is not accessible from this node. The fault can be permanent or temporary. One of two redundant links is in the operational state DISABLED. remote remote and/or field The alarm is issued if the Ethernet Switch detects a "port fault" condition. The operational state of the port is changed to DISABLED. The alarm remains as long as the port is faulty. Normally, the fault must be attended to on site. Causes: Link Down remote and/or field EWS event, not a fault The alarm is issued when an ete Alarm Indication Signal (end-to-end AIS) cell is received in the F5 Operation and Maintenance (O&M) flow of the Virtual Circuit (VC). The alarm is issued if the Ethernet switch port is overloaded. The load is 100% or more of the maximum allowed load. The alarm remains as long as the port is overloaded and ceases automatically when the load decreases. If the Ethernet switch port load decreases, this alarm is replaced by the alarm, Ethernet Switch Port Congestion. none none remote remote and/or field Link Failure Remote IP address unreachable. remote and/or field remote and/or field An alarm is issued when the Message Transfer Part level 3 (MTP3) detects a faulty M3UA Association. The fault can be permanent or temporary. The possible causes are as follows: remote a transmission fault a process or processor restart in this node a faulty General Purpose processor Board (GPB) a fault in the adjacent signalling node The alarm is issued when a specified number of the consecutive bad seconds has been detected. A second is defined as "bad" if the detected percentage of the block errors is equal to, or greater than, the specified percentage. The values of the bad seconds (vcDegM attribute in the MO, Vc4Ttp) and errored blocks (vcDegThreshold attribute in the MO, Vc4Ttp) can be specified. The default values are 7 seconds and 30%, respectively. The alarm indicates that the VC4 (Virtual Channel) path through the Synchronous Digital Hierarchy (SDH) transport network is affected by bit errors. Invalid downlink code configuration The alarm is generated when the C2 byte received in Virtual Container 4 Path Overhead (VC4 POH) contains the pattern “00000000” in five consecutive frames. The alarm indicates that there is no payload on the affected VC4. As a consequence of the fault, the traffic on the affected VC4 path is lost. Device Disabled event, not a fault remote and field remote remote remote remote and/or field none There is no configured link with operational state ENABLED. event, not a fault event, not a fault remote and/or field none none event, not a fault none The alarm is generated when an Multiplexer Section Alarm Indication Signal (MS AIS) is detected in the K2 byte. As a consequence of the fault, the traffic on the affected Synchronous Digital Hierarchy (SDH) link is lost. The likely cause is that the MS is affected by the fault in the remote node. Transport network errors between the RNC and the remote RNC A restart in the remote RNC or intermediate system A Radio Network Subsystem Application Part (RNSAP) failure in the RNC or the remote RNC remote and/or field The alarm is issued when an ete RDI (end-to-end RDI) cell is received in the F5 Operation and Maintenance (O&M) flow of the Virtual Circuit (VC). The fault is not in the local node, but in a remote node, or between the two nodes through which the VC is routed. The remote node can be a Plesiochronous Digital Hierarchy (PDH) or an Synchronous Digital Hierarchy (SDH) network element, or an ATM switch. Alarms, for example, Loss of Signal and Loss of Frame, identifying the failed entity, are reported from the network element that detected the fault. As a consequence of the fault, the traffic is lost. If the repair of the fault requires site visits, it might be feasible to use an alternative VC for the traffic. A Denib device is any hardware device that is monitored utilizing the Denib protocol. Denib is an Ericsson proprietary protocol used when communicating with certain hardware devices through a serial connection. remote remote remote Cell down yes Capacity reduced yes Performance impacted yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes SAF yes yes yes yes yes yes yes yes yes yes yes yes no maybe no yes no maybe maybe yes maybe no no no no no no yes yes no yes yes no no yes yes yes no yes yes yes yes yes no yes yes maybe yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes no no yes no no yes no no yes yes yes no no yes no no no no yes yes maybe yes yes no maybe maybe no no no no no no no yes yes no yes yes no yes yes no yes yes yes no no yes yes yes no yes yes no no no yes no maybe yes yes no no maybe no no yes no no maybe maybe yes yes maybe no maybe yes maybe yes no yes yes maybe maybe yes yes yes yes no maybe yes yes yes yes no no yes no yes no yes no no yes yes yes yes yes yes yes yes yes yes no maybe no no yes no no yes no no no no no yes no no no maybe yes yes no yes yes maybe yes yes no no no yes yes yes no Severity Indeterminate Indeterminate Indeterminate Indeterminate Indeterminate Major Specific problem Ip over ATM Link Supervision Recovered Ip over ATM Link Supervision Failed NssSynchronization_SynchRefChanged NssSynchronization_SystemClockStatusChanged AuxPlugInUnit_SuccessfulRecoveryActionPerformedReestablishLink NTP Server Reachability Fault Counts 140633 132560 98702 90814 59183 45496 Indeterminate E1PhysPathTerm_NoCRC4Mfa Warning PDH Alarm Indication Signal 40204 37800 Minor Unknown Indeterminate Major AlmDevice_ExternalAlarm Synchronization Start Synchronization End IMA Group Configuration Aborted 36907 24432 21853 20092 Warning IMA Link Reception Unusable at Far End 18398 Minor Warning Anomalia funzionale CDZ Remote Defect Indication on IMA Link 14751 14651 Major Major Critical Indeterminate Minor Critical Major Synch Reference Path HW Fault LossOfMains Heartbeat Failure Extensive Ethernet frame flooding Loss of Synch Reference Redundancy Anomalia impianto elettrico System Clock in Holdover Mode 14144 14041 12192 10182 9999 9908 8751 Major IMA Group Insufficient Links 8138 Minor Remote IP Address Unreachable 7722 Minor PDH Degraded Signal 7294 Major FcuDeviceGroup_NumberOfHwEntitiesMismatch 6770 Major IMA Group Insufficient Links at Far End 6210 Major PDH Loss of Frame 5699 Major Synch Reference Not Reliable 5402 Major Carrier_RxDiversityLost 5055 Critical Critical Critical Major Anomalia di blocco CDZ Anomalia interruttore generale None AntennaBranch_FeederCurrentTooLowInBranchA 4466 4367 4336 4179 Major PDH Loss of Signal 3908 Minor DownLinkBaseBandPool_DLHWLessThanDLCapacity 3902 Major Gigabit Ethernet Link Fault 3720 Critical Mancanza rete Indeterminate RuDeviceGroup_SuccessfulRecoveryActionPerformedBoardRestart Major AntennaBranch_FeederCurrentTooLowInBranchB 3597 3302 2933 Indeterminate Synchronization Aborted Critical NbapCommon_Layer3SetupFailure 2655 2589 Major AntennaBranch_AntennaProblemInBranchA 2486 Critical Minor Allarme porta aperta UpLinkBaseBandPool_ULHWLessThanULCapacity 2296 2219 Major Loss of Tracking 2201 Major AuxPlugInUnit_CommunicationLostWithAsc 2186 NodeBFunction_NodeRestarted NodeBFunction_OaMApplicationRestarted Allarme incendio PIU restarted 2060 1927 1768 1447 Indeterminate Indeterminate Critical Indeterminate Indeterminate RuifDeviceGroup_SuccessfulRecoveryActionPerformedReestablishLink 1408 Major RuDeviceGroup_TemperatureExceptionallyHigh 1353 Major RuDeviceGroup_GeneralSwError 1349 Major Carrier_SignalNotReceivedWithinTime 1284 Major TimDevice_RadioClockIsNotStable 1059 Critical Major Anomalia batterie Ethernet Switch Port Fault 1059 1046 Major Loss of IMA Frame 956 PDH RNCI 924 Anomalia SOV 905 Warning Critical Major DbccDevice_GammaDownlinkFailure 807 Major Major DigitalCable_Disconnected CluDeviceGroup_EnclosureDoorOpen 733 713 Major SystemOvervoltage 711 Critical Major Minimo Batterie S.E.

That is, the two nodes have conflicting configuration data. The IMA group rejects the configuration data received from the corresponding IMA group in the remote (far-end) node. The alarm is issued when the Inverse Multiplexing ATM (IMA) link at the far end has become unusable. It is likely that a corresponding alarm has been issued at the local node for the faulty IMA link. external alarm The possible causes are as follows: a loss of cell delineation a fault in the physical layer Fault in the synchronization reference path Commercial Power Failure Link failure All but one of the defined Synchronization references are unavailable external alarm TU Synch Reference Loss of Signal Network Synch Time from GPS Missing Loss of Tracking Synch Reference Path HW Fault Synch Reference Not Reliable PDH physical path termination: PDH Loss of Signal, PDH Loss of Frame, PDH Alarm Indication Signal, PDH Degraded Signal, Plug-In Unit HW Failure, or ET Hardware Fault. SDH physical path termination: Loss of Signal, Loss of Frame, MS Alarm Indication Signal, MS Degraded Signal, MS Excessive Bit Error Rate, Plug-In Unit HW Failure, or ET Hardware Fault. IP Synchronization reference: NTP Server Reachability Fault, or Gigabit Ethernet Link Fault The alarm is issued when one or more Inverse Multiplexing ATM (IMA) links have failed, reducing the number of working IMA links within the IMA group to fewer than the configured "required no of links" for the IMA group. Remote IP address unreachable. The possible causes are as follows: a faulty board a service degradation on the optical receiver a faulty laser a transmission media fault the alarm, PDH Remote Defect Indication The most likely causes of the alarm are: A faulty or disconnected fan unit cable Too few fans installed The alarm is issued when one or more Inverse Multiplexing ATM (IMA) links have failed at the remote (far-end) node, reducing the number of working IMA links within the IMA group to fewer than the configured "required number of links" for the IMA group. The possible causes are as follows: misconfigured framing between this and the remote node The most likely misconfiguration is a wrong setting in the attribute, crc4Mode in the MOs, E1PhysPathTerm or E1Ttp.

Hardware failure in the TX board or in the DUW decreases the available capacity below the capacity defined by the License Key (LK). Ethernet switch or router, or the network to which the links are connected, is faulty. Board or Ethernet link is faulty. There is no configured link with operational state ENABLED. external alarm event, not alarm Incorrectly connected feeder or jumper cable (if the alarm is raised immediately after antenna installation) Antenna feeder short circuit Damaged or loosely connected jumper cable RET Interface Unit (RIU) Remote Electrical Tilt Unit (RETU) AISG/3GPP Remote Electrical Tilt Unit (ARETU) External Tower Mounted Amplifier (TMA) Antenna System Controller (ASC) AISG/3GPP Tower Mounted Amplifier (ATMA) event, not alarm The Layer3SetupFailure alarm is issued for the Node B Application Protocol (NBAP) Common, and means that a signalling bearer is established and the Radio Base Station (RBS) requests an audit but the Radio Network Controller (RNC) is unable to initiate an audit at setup.

The alarm is also issued for a limited period of time for a Switch Core Board (SCB) or a Control Board Unit (CBU) in connection with upgrade, and node and board restart. event, not alarm The alarm indicates that software cannot be downloaded for the component for which the alarm is issued. The consequences of the fault, and the subsequent corrective actions, depend on the board or unit for which the alarm is issued, and the RBS configuration. event, not alarm The alarm indicates that a component is faulty and must be replaced. event, not alarm external alarm A faulty Alternating Current Connection Unit (ACCU) A fault in the Remote Radio Unit (RRU), or with the incoming power A faulty cable between the Climate Unit (CLU) and the ACCU, or a fault in the CLU which consequently works with reduced capacity A fault in the incoming power supply. The severity of this alarm is related to the capacity of the battery backup system The RBS is running on batteries. The RBS remains functional as long as the battery backup system has enough capacity. The RBS is running on batteries. The RBS remains functional as long as the battery backup system has enough capacity. A fault with the incoming power If the alarm is issued by one or a few PSUs in the RBS, then the probable cause of this alarm is a faulty power cable or a fault in the Power Supply Unit (PSU). Depending on configuration, the RBS can remain functional with one or more faulty PSUs. If the alarm is issued by one or a few PSUs in the RBS, then the probable cause of this alarm is a faulty power cable or a fault in the Power Supply Unit (PSU). Depending on configuration, the RBS can remain functional with one or more faulty PSUs. If the alarm is issued by all PSUs in the RBS, then the probable cause is a fault in the incoming power supply. The severity of this alarm is related to the capacity of the battery backup system. Cables carry the gamma link between the following: the Baseband Interface (BBIF) and Radio Frequency Interface (RFIF) boards; the Optical Baseband Interface (OBIF) board and the RRU; the Radio Unit Interface (RUIF) and the Radio Unit (RU). Between all other boards, the physical connections are made through the backplane of the boards. The alarm indicates clock failures or a broken clock path. A software fault An incorrect version of the software A faulty configuration, depending on a software error (only when RruDeviceGroup issues the alarm) The likely cause is one of the following: The cause of the problem is usually not the unit issuing the alarm, but climate or environmental reasons. RBS Temperature Out Of Range offers a systematic procedure for determining the correct cause. A battery temperature sensor fault Battery failure The LeftFanSpeedTooLow alarm indicates that there are faults in one or more of following units: BaseBand (BB) Subrack Fan Unit Radio Frequency (RF) Subrack Fan Unit Multi-Carrier Power Assembly (MCPA) Subrack Fan Unit Power Subrack (PS) Fan Unit If the fan units need to be replaced, then do it at the next planned service of the RBS. The consequence of this alarm is that different RBS components can be overheated. event, not alarm external alarm external alarm external alarm external alarm external alarm external alarm Too many counters. A software fault An incorrect version of the software A faulty configuration, depending on a software error (only when RruDeviceGroup issues the alarm) event, not alarm event, not alarm This alarm is issued by the Bfu Managed Object (MO) or the BfDevice MO when the RBS is running on batteries only and the battery voltage is below a certain operator-defined or hardware default level. To protect the batteries from damage, the RBS is disconnected. Normally this alarm never reaches the operator, because the RBS is disabled when the alarm is issued. The alarm BatteryVoltageSupervisionTooLowMainLoadDisconnected is sent in advance. This alarm is issued by the Bfu Managed Object (MO) and the BfDevice MO when the RBS is running on batteries only and the battery voltage is below a certain operator-defined or hardware default level. To protect the batteries from damage, the RBS is disconnected except for equipment connected to prioritized outputs. This alarm indicates one or more of the following faults: A faulty capacitor compressor A faulty expansion valve A faulty compressor A refrigerant leak If the cause of the problem is not the unit issuing the alarm, it could be climate or environmental reasons. If so, RBS Temperature Out Of Range offers a systematic procedure for determining the correct cause. event, not alarm The board or unit issuing this alarm is unable to carry traffic. If the alarm is issued by a nonredundant board or unit, the RBS is unable to carry traffic. Cables carry the gamma link between the following: the Baseband Interface (BBIF) and Radio Frequency Interface (RFIF) boards; the Optical Baseband Interface (OBIF) board and the RRU; the Radio Unit Interface (RUIF) and the Radio Unit (RU). Between all other boards, the physical connections are made through the backplane of the boards. The alarm is issued by the HwUnit MO (1) with hardware unit type PSU (2). The alarm is raised when the PSU operating temperature is too high and the PSU performance is reduced. external alarm DigitalCable LoPowTxCable RfCable TrxRfCable external alarm The alarm is issued by the OptoCommCable Managed Object (MO) when the communication between the different units in the RBS power supply system has failed. When this alarm is issued, the power system control function (POSS) cannot communicate with the Main Processor (MP). No other alarm can be sent from the POSS units. A software fault An incorrect version of the software A faulty configuration, depending on a software error (only when RruDeviceGroup issues the alarm) The most likely causes of this alarm are: The number of configured PSUs is less than the actual number of PSU units The number of configured PSUs is more than the actual number of PSU units external alarm external alarm external alarm external alarm external alarm external alarm external alarm external alarm external alarm external alarm external alarm event, not alarm external alarm external alarm A software fault An incorrect version of the software A faulty configuration, depending on a software error (only when RruDeviceGroup issues the alarm) This alarm is issued by the NodeBFunction Managed Object (MO) when the AISG/3GPP Tower Mounted Amplifier (ATMA) is configured without a valid license. event, not alarm external alarm external alarm The alarm indicates that a component is faulty and must be replaced. event, not alarm Cables carry the gamma link between the following: the Baseband Interface (BBIF) and Radio Frequency Interface (RFIF) boards; the Optical Baseband Interface (OBIF) board and the RRU; the Radio Unit Interface (RUIF) and the Radio Unit (RU). Between all other boards, the physical connections are made through the backplane of the boards. The alarm can be issued for the following reasons: Slow rotation of the fan caused by defects in the bearings Defects in the fan motor A blown fuse If the cause of the problem is not the unit issuing the alarm, it could be environmental reasons. If so, RBS Temperature Out Of Range offers a systematic procedure for determining the correct cause. This alarm is raised when the battery temperature sensor is detected to be faulty. Damaged or incorrectly connected feeder cable Damaged or incorrectly connected power and signal cable between Radio Unit (RU) and Filter Unit (FU) A faulty TUB/CBU/DUW. If the RBS is configured with two redundant TUBs, then the alarm indicates that both TUBs are faulty. A faulty Radio Unit Interface (RUIF) board, or Radio and Enclosure Interface (REIF) board. A faulty timing cable. A faulty RFIF or BBIF board. Faulty TU external alarm Unconfigured external alarm A faulty or incorrectly connected Radio Frequency Interface (RFIF) board to Baseband Interface (BBIF) board timing cable A faulty RFIF board A faulty or detached BBIF board A faulty or incorrectly connected Baseband Interface (BBIF) board to Radio Frequency Interface (RFIF) board timing cable A faulty RFIF board A faulty or detached BBIF board event, not alarm The causes of the alarm are (depending on the RBS type): A faulty or disconnected gamma cable or digital cable A faulty BBIF board A faulty Digital Unit WCDMA (DUW) A faulty RFIF board A faulty Single Transceiver Board (sTRX) A faulty OBIF board A faulty Transmitter (TX) board A faulty RU A faulty RUIF board A faulty REIF board The various faults can be synchronization, alignment, parity, or ID.
