Elements and Performance Criteria

1. Analyse signalling and digital path alarms and clear network faults
   • Obtain relevant legislation, codes, regulations and standards to prepare for the task
   • Activate alarm management system to produce a trouble report and verify common channel signalling (CCS) and data faults or problems
   • Investigate cause of alarm and analyse results to determine appropriate repair action and allocate resources
   • Monitor repair and restoration procedures to ensure commitment to specified timelines and initiate escalation procedures as appropriate and according to enterprise procedures
   • Reset alarms on completion of repair and monitor subsequent alarms to ensure no re-occurrence of the problem
2. Monitor integrity of data received on equipment ports
   • Activate alarm screens and monitor port times on a regular basis to ensure procedures are running
   • Clear port blockage and problems on completion of planned works and log in appropriate database
   • Monitor repair and restoration procedures to ensure commitment to specified timelines and initiate escalation procedures as appropriate and according to enterprise procedures
3. Monitor and acceptance test repair
   • Verify network stabilisation throughout repair and monitor repair action to ensure minimal impact on the overall network
   • Undertake acceptance testing according to prescribed operating procedures
   • Monitor network stability on completion and refer problems to appropriate area for action
   • Block alarms for out-of-service circuits
4. Coordinate CCS relationships
   • Log requests for relationship change and follow up problems with appropriate support staff
   • Monitor network stability and manage loading of data until the process is completed
   • Update models and enterprise systems
5. Coordinate CCS rearrangements
   • Log requests for rearrangement scenarios and verify feasibility of the rearrangement
   • Enter details of rearrangement in appropriate system and update system records
   • Monitor completed work for accuracy and network stability on completion
   • Produce a copy of documentation for future reference

Performance Evidence

Evidence of ability to:

identify and implement repair action within service assurance guidelines

analyse and interpret alarms including common channel signalling (CCS) and digital path

apply enterprise fault management priorities and escalation procedures

resolve problems in a methodical and logical manner

conduct appropriate tests and interpret results.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
