Optus offshoot and digital subscriber line (DSL) provider XYZed has completed its national network which now covers Sydney, Canberra, Melbourne, Brisbane, Perth and Adelaide and key metropolitan areas of these centres.
A partial rollout of the company's network (in Melbourne and Brisbane) was announced in March.
The company said it has 103 exchanges providing high-speed DSL services, which reach about 75 per cent of businesses in coverage areas.
The network consists of 40 exchanges in Sydney and surrounds, two in the ACT, 28 in Melbourne, 13 in Brisbane, 11 in Perth and nine in Adelaide.
Construction of the XYZed network began in April 2000 when the company was formed as an independent subsidiary of Cable & Wireless Optus.
