Troubleshooting and Repair

Enhancing alarms paging delivery time

To determine whether better performance is possible, first determine whether the problem

is within the control of the OPS Manager station (the problem could be at the service

provider’s end). Isolate and possibly rectify the problem as follows:

Determine the frequency at which pages are being generated (the logs viewer will help to

quantify this). Some things to look for include

• Are pages being generated by problems relating to a single PABX in the Network?

• Are pages being generated in groups, for example at a certain time each day?

• How many pages were successful/unsuccessful?

• Are failed pages caused by problems at the far end? (busy destination at the paging

service provider device)?

• Are the failures due to hardware problems at the local end (OPS Manager platform or

modem)?

Determine whether the delay being experienced is legitimate; for example, are the pages

from various elements and at various times of the day. If the problem is the sheer volume

of pages being generated, the user should define a second serial port/modem for the

paging application to reduce resource contention.

If the pages are in groups or relate to a single element, the problem may be at a particular

site. Investigate further to determine what is causing the alarms (it is best to correct the

problem at the site). If correcting the problem will take considerable time, turn off alarm

notifications from the PBX until completed. If the pages are due to the PBX toggling

between two alarm states (clear and minor), disable pages for the offending alarm level

until the problem is corrected. If turning off notifications is unacceptable, reduce the volume

by removing the offending PABX from as many pagers’ “selected” lists as possible (only

one pager should keep the PABX in its list) to reduce the number of notifications that are

sent each time the PABX reports an alarm transition.

Another solution is to change the PABX thresholds for the particular category that causes

the alarm until the fault is repaired (other problems will still be reported).

If the problem is caused by the far end (such as busy destination devices), contact the

service provider.
