Cable & Wireless Optus Limited has notified the Australian Competition and Consumer Commission of two access disputes with Telstra Corporation under Part XIC of the Trade Practices Act 1974.

The disputes relate to certain terms and conditions on which Telstra supplies and proposes to supply Optus with Integrated Services Digital Network (ISDN) Originating and Terminating Services.

Accordingly, the ACCC has begun the arbitration process.

Given that the legislation contemplates that arbitrations be conducted in private the ACCC will not be making any public comment at this stage.
