Customer Case Study
Network Solution
Transparent integration was the key requirement for Optus in moving to an end-to-end, Quality of 
Service (QoS) enabled, IP network platform. In their search for an implementation partner, Optus 
decided that a full Cisco IP network would be the ideal choice for their communications needs. In 
particular, they were impressed by the willingness of the combined Cisco and Alphawest team to 
provide detailed demonstrations of the technology in action, and how the technology would bring about 
real productivity and operational benefits for their staff.
Being an existing user of Cisco core networks was also a deciding factor. As Optus Director Corporate 
Services, Jon Wilkie says, “Our previous offices used Cisco networks, so we were already familiar with 
the capabilities of the products. Optus’ positive experiences naturally led us to asking Cisco about what 
solutions would best suit the needs that Optus had for such an important project.”
 The proposed solution included a core network of Cisco Catalyst 6500 Series Switches, providing 
approximately 11,000 LAN ports and intrusion prevention systems. To provide telephony features, more 
than 7500 units of Cisco 7941G IP Phones were deployed. The network has also been provisioned 
to run the Cisco Unified Personal Communicator software. This is a productivity tool that provides
presence and contact preference information, call history, click to dial, and voicemail access from the 
desktop. In turn, the software is delivering significant benefit in consolidating communications media in 
Optus.
The Optus contact centre will be powered by the Cisco Unified Contact Centre Solution, providing
intelligent routing of service calls to appropriate agents anywhere on the campus, based on resource 
availability, and provide them with detailed customer profiles for individualised service. The solution 
would create one of the largest call centres running on Cisco technology in the Asia-Pacific market. The 
Cisco solution is an extension of the existing Hosted Unified Contact Centre platform, which supports
Optus’ other internal contact centres and also provides contact centre services to more than 80 Optus 
corporate and government customers.
Optus also wanted to employ wireless as an overlay technology throughout the campus to further boost 
productivity. The Cisco team was able to provide a secure wireless connectivity model for the campus 
that could be managed from the same central console as the rest of the Cisco network.  Optus was 
impressed with the Cisco and Alphawest team’s ability to demonstrate and test how the wireless LAN 
(WLAN) would be integrated with the wired LAN.
As a result, Optus decided to also invest in the Cisco Unified Wireless Solution, deploying some 230
Cisco Wireless 1130 Access Points (APs) throughout the campus. By adding the Cisco wireless local
area network (WLAN) Access Controller for Catalyst 6500 Series Switches, all elements of security, 
mobility, Quality of Service (QoS), and other functions essential to WLAN operations could be efficiently 
managed across the entire wireless enterprise. Further, with the extremely lightweight Cisco wireless
APs receiving power via their LAN cables, there is no need to install separate, expensive electrical 
cables.
The use of the Cisco WLAN Location Appliance allows tracking of the physical location of wireless 
devices to within a few meters, and the Cisco Building Broadband Service Manager (BBSM) provides 
Internet access management features and functionality to wired and wireless networks for guests on 
the campus.
The WLAN / LAN solution also includes a demonstration of Network Access Control (NAC), showing 
how devices connected to the wireless network can be checked dynamically to help ensure that 
they meet corporate security requirements, such as having the latest software patches, and security 
updates.
 “As our 18 month relationship with Cisco and Alphawest on this project progressed, we realised how 
important our decision was to appoint a single vendor solution for our fully integrated end-to-end 
solution,” says Wilkie.
