On 30 September 2010 the ACCC issued a final report varying the domestic transmission capacity service (DTCS) declaration. In the final report the ACCC decided to vary the DTCS service description to include Ethernet network interfaces. The declaration expires on 31 March 2014.
The ACCC held a public inquiry on the DTCS declaration pursuant to subsection 152AL of the Trade Practices Act 1974. The purpose of the review was to clarify whether the DTCS declaration service description covered all commonly used network interfaces on transmission networks in Australia such as PDH (Plesiochronous Digital Hierarchy), SDH (Synchronous Digital Hierarchy) and Ethernet network interfaces.
