Australian telecommunications operator Optus has completed the first Australian implementation of a multi-point Cisco TelePresence service across three different locations in Sydney and Melbourne. Optus is also trialling Asia Pacific's personal TelePresence system, the Cisco TelePresence System 500, which will be deployed in conjunction with the multi-point service at its new headquarters in Sydney's Macquarie Park. The service was implemented by Optus' ICT services arm Alphawest and was built on the Optus Evolve IP network. It includes the implementation of a three-screen Cisco TelePresence System 3000 unit at the Optus Macquarie Park campus in Sydney and the Optus Collins Street office in Melbourne and a single screen Cisco TelePresence System 1000 at Alphawest's Sussex Street offices in Sydney. The TelePresence implementation serves to reinforce Optus and Alphawest's ongoing expertise and experience in unified communications services for large enterprises and Cisco technologies.
