Minor Alarms 1 Action, Margin Threshold | Paradyne 8310 MVLt

Diagnostics and Troubleshooting

Minor Alarms

Use Table 6-3 to determine the appropriate action to take for each Minor Alarm.

Table 6-3. Minor Alarms (1 of 2)

Alarm

Action

Config Error 1. Check the Selftest Results display by following the menu selection sequence: Diagnostics → Selftest (D-A)

2.Do another Selftest (Reset) and check results.

±If the results are normal, the problem was transient. Log the results.

±If the results still show configuration corruption, there is a card problem. The card's nonvolatile RAM should be erased and the configuration reentered. Perform a configuration download.

±If the configuration has not been saved, use reset and erase NVRAM to force the card to the factory default. Enter the basic default route to the MCC and reconfigure the card manually.

NOTE: The following are minor alarms where thresholds have been exceeded and are primarily indications of degraded quality on the DSL loop. They are not necessarily related to problems with the DSL card.

Margin Threshold

(A trap message is sent if margin falls below selected value.)

HIf DSL speed is set to a Fixed Rate, you may choose to lower the speed in the direction indicated by the threshold alarm (Fixed Up Speed or Fixed Down Speed) to get a better Margin and improved error performance.

HIf DSL speed is set to Rate Adaptive and the Margin Threshold is

greater than 0, this alarm is a warning that the loop has degraded. The actual bit rate should still be above 10-7. This condition may be temporary due to high temperature or humidity/rain, or it may be permanent due to high noise from additional digital circuits installed in the same cable bundle.

HIf DSL speed is set to Rate Adaptive and the Margin Threshold is

greater than 0, this alarm is a warning that the loop has seriously degraded. The actual bit rate may be below 10-7. This condition may be temporary or permanent. However, if it persists, the loop may have to be reengineered for better performance by performing one of the following:

±Remove bridge taps.

±Change cable gauge on a cable section.

±Run new cable.

±Remove other noise-generating digital circuits from the cable bundle.
