@Leon51, I really need a bit of clarification.
What details are we to include in the letter of provisioning?
If you're looking at installing copper lead in cables, you'd need to direct your enquiry to Telstra.
Optus provides Cable services over HFC to usually stand alone dwellings and at most side-by-side duplex. If Cable is not available then we would offer services via ADSL and copper lines provided by Telstra.
Let us know, we're happy to try and help out.
