Snapshot of use of Telstra's customer access network

The snapshots have been prepared from data that Telstra has provided to the ACCC under the Telstra customer access network record keeping rule (Telstra CAN RKR).

Under the Telstra CAN RKR, Telstra reports the total number of unconditioned local loop service (ULLS), line sharing service (LSS), voice and DSL services for each quarter. The data is disaggregated by individual provider on an exchange service area (ESA) basis. The information demonstrates the extent to which Telstra and access seekers have invested in digital subscriber line access multiplexer (DSLAM) equipment.

Under a disclosure direction made by the ACCC on 14 August 2008, Telstra is required to provide a snapshot of the data marked for public release on a quarterly basis.

For the purposes of preparing the snapshot, the data is aggregated into geographic areas (ULLS bands).

The ULLS bands are as follows:

• Band 1 ESAs are in central business districts
• Band 2 ESAs are in metropolitan areas (more than 108.4 services in operation (SIOs) per square km)
• Band 3 ESAs are in regional and rural areas (more than 6.54 SIOs per sq km)
• Band 4 ESAs are in remote areas (less than 6.55 SIOs per sq km).

Maps of the four ULLS bands are available to aid in the interpretation of the snapshots.
