aiPort

Warning

alarmInp

Alarm condition on alarm-in port

The NEs provide four auxiliary alarm inputs (dry contact alarms) for associated equipment. For example, power module failure, battery condition, and open cabinet door. The operator can set the alarm to be triggered on either open or closed contact.

au4

Minor

ais

Alarm Indication Signal (AIS)

When an NE detects a defect in the regenerator section (RS) or the multiplexer section (MS) of an incoming link, the payload of that link is invalid. The NE then replaces the payload with an AIS in the forwarding direction.

All subsequent NEs detect AU-4 AIS.

Note: By default, the alarm is suppressed.

If AIS occurs for AU-4, verify alarm conditions on sections between intermediate nodes on the path.

au4

Critical

lop

Loss Of Pointer

AU-4 Loss of Pointer (LOP) occurs when an NE is unable to interpret the AU-4 pointer. This alarm normally indicates that the NE receives concatenated AU-4s when the NE actually expects non-concatenated AU-4s.

Ensure that connected STM-n ports maintain the same structure on both ends.

4

au4

Major

epj

Excessive Ptr Justification

This alarm appears if the number of Pointer justification events (PJEs) over a 15-minute period is greater than a threshold that you can configure, or the PJEL (Pointer Justification Event Limit).

You can configure the PJEL individually for each AU-4 from 1 to 1024 events. The default configuration is 100 events per interval.

PJE, both positive and negative justifications, are counted and measured over a 24-hour interval. Both current and past 24-hour interval counters are available.

This alarm indicates synchronization problems in the network. The likely cause is that the devices operate with different sync-sources. For example, interconnected devices that operate in "free running" mode cause this alarm per AU-4 object.

The alarm clears when the number of received pointer events is lower than the set threshold within a full 15-minute interval.

au4

Warning

switchWork

SNCP switched to “working”

This event occurs if the traffic switches from “protecting” to “working”.

Switching criteria depend on SNCP type. In other words, the criteria depend on whether SNCP is SNC/i or SNC/n. The main difference between the two is that in addition to a switch on AIS/LOP alarms, SNC/n also switches on (non-intrusive) UNEQ/TIM/DEG/EXC alarms.

-

27

device

Warning

alarmStormEnd

Alarm storm end detected

This alarm appears when the number of alarm status changes reduces to a level where all alarms show up as traps again.

In a situation where alarmStormStart appears, the current alarm-list can be wrong before alarmStormEnd appears.

The list can show alarms that are no longer present, and there can be active alarms that are not in the list. Also, for some alarms, the time-stamp can be wrong.

In this situation, the alarm history can also be wrong. Some alarm conditions could have been present and disappeared again, and probably did not appear in the alarm-lists. Also the time-stamps can be wrong on some alarms or events.

After alarmStormEnd goes out, the system updates the current-alarm-list, and every alarm from that point in time appears in the alarm-history.

inletBitError

DXC inlet bit error

Cards with EoS mappers can experience packet losses. For example, LAN traffic mapped to EoS ports on 8xSTM1+map module, and "DXC inlet bit error alarm" conditions can occur when you expose 8xSTM1+map cards to extreme temperature cycles (-5 to 50°C with 2 hours dwell at each extreme temperature, and 1°C/min gradients). The packet losses and condition can occur on the 8xSTM1+map card. This only occurs under temperature stress. The frequency with which the issue occurs is an average of 10 packets lost, and less than 100 alarms recorded in a 12 hours cycle. Nominal conditions record no failures.

cardIsolated

Card isolated

The 'card isolated' error can occur in these conditions:

1. A card anomaly occurs while the module is in-service:

   1. Module removed (extracted from the chassis).

   2. Module failed (power loss on the module).

   3. Dxc inlet failure (interface between main-card and the module).

      Note: If a) or b) or c) occurs on pure SDH/PDH modules, an alarm appears.

      • Card_removed (A)

      • Card_anomaly (B/C)

      If a) occurs on modules with switch (8xstm1_map/8xfe/2xge/4xfe_map/8xmap) an alarm (card_removed) appears, BUT, in addition the complete device restarts, due to recovery/clean-up handling of the crossbar or switch system. When the device is up again, the card_removed alarm is still present.

      If b) or c) occurs on modules with switch (8xstm1/8xfe/2xge/4xfe_map/8xmap) an alarm (card_anomaly) appears BUT in addition, the complete device restarts, due to recovery/clean-up handling of the crossbar or switch system. When the device is up again, the failed module is marked "ISOLATED".

2. On a module (with switch - 8xstm1/8xfe/2xge/4xfe_map/8xmap) the hot-removal process fails when you shut down the module. Again the system restarts, due to recovery/clean-up handling of the crossbar or switch system. When the device is up again, the failed module is marked "ISOLATED".

When a module ends up in an "ISOLATED" alarm-state, not caused by physical handling, you must replace the module.

This alarm appears when an AC module receives more than 255VAC from the 230VAC outlet.

The module disconnects the output voltage and activates an alarm if the output voltage is outside the specified tolerance (Higher than 6V or less that 5V). The module also limits the maximum output current to 11A.

Trace Identifier Mismatch

Trace Identifier Mismatch occurs when you have enabled path trace and the “received string” is different from the “expected string”.

This alarm condition stops traffic.

Verify the configured string at both ends of the physical connection.

You do not need to set the Path Trace Identifier attributes, but you can use the tool to check the connectivity of complex networks. Basically, a Path Trace Identifier is inserted at the start of a path and extracted at the end of a path.

When you set Path Trace Transmitted to a logical value, (such as, "BONN-3-21") you can check whether the other side of teh network receives this value. If you enter a value for the Path Trace Expected and enable Path Trace, a TIM alarm appears if the received value is different from the transmitted value.

Out Of Frame

The out of frame (OOF) alarm appears when the frame sync in not recognizable. OOF condition results in a loss of frame (LOF) alarm, if persistent in 3ms.

Open the statistics report (RS) for the port and look for evidence of a bad line. Bit errors can indicate a timing problem. If you find evidence of a bad line, isolate the problem. For this, physically loop the ports with a cable at each end of the connection.
