Network Reliability Framework for fixed voice services

Telstra prides itself on its level of service and this website presents the latest monthly data showing you the reliability of Telstra's fixed voice network (based upon Telstra fixed voice services that are subject to the Customer Service Guarantee) nationally and across 44 metropolitan and regional areas as set out in the table below. A map of each of the geographic areas listed can be obtained by placing your cursor on the name of the area and selecting it.

Two measures are included for each area:

  1. The "Percentage of Customer Service Guarantee (CSG) Services* with no faults" in any given month.
    This measure describes the percentage of CSG Services that were fault-free in the month nationally and within each of the geographic areas. The table shows a very high percentage of services experiencing no faults on a monthly basis.
  2. The "Average Service Availability" in any given month.
    This measure means the percentage of time on average that CSG services were operational nationally and within each of the geographic areas, as a percentage of total time per month. The graph shows that this measure is mostly above 99.9 per cent, confirming very high levels of availability for CSG services.

Together, results for the two measures show that the vast majority of CSG services in any given month are fault-free and that where faults do occur, they are fixed promptly.

  • The Customer Service Guarantee (CSG) is a regulated performance standard that sets down maximum timeframes for the connection and rectification of fixed voice services for residential and small business customers.
