OBS_VALUE: On 27 February 2012 the ACCC accepted Telstra’s SSU that commenced on 6 March 2012. Telstra’s structural separation will occur progressively—through Telstra ceasing to supply fixed-line voice and broadband services over its copper and Hybrid Fibre Coaxial (HFC) networks and commencing to supply those services over the NBN as the fibre network is rolled out. The SSU included a number of obligations to promote competition during the interim period from the date that the SSU commenced until the completion of the NBN fibre network. Under its SSU, Telstra commits to supplying financial reports drawn from its Economic Model (TEM), for publication by the ACCC.Additional Source: Telstra's Migration Plan [https://www.accc.gov.au/regulated-infrastructure/communications/industry-reform/telstras-migration-plan]. According to the Migration Plan, the designated day for the completion of Telstra's structural separation was 1 January 2020 (https://www.communications.gov.au/what-we-do/internet/competition-broadband/telstras-separation-framework). Upon its completion, Telstra no longer controls the fixed-line telecommunications network that competitors use to service most Australian premises. Under the National Broadband Network Companies Act 2011 (Part 2, Division 3), an NBN corporation may be required to prepare a draft functional separation undertaking and must comply with a final functional separation undertaking given by the NBN corporation (https://www.legislation.gov.au/Details/C2020C00171).See also: https://www.accc.gov.au/regulated-infrastructure/communications/fixed-line-services/superfast-broadband-network-class-exemption-deemed-functional-separation-undertaking
