Infrastructure refresh wired for VoIP success

ROI within 18 to 24 months

Bwired is in the business of smart solutions which is why the company looked to Voice over IP (VoIP) technology for a voice and data infrastructure refresh.

The Melbourne-based company specialises in the deployment and management of smart buildings and selected VoIP to provide voice and data services to the commercial tenants set to occupy one of its buildings.

The building includes 56 suites with an average of three users per suite, and 78 single user offices for a total of around 250 sites.

Telecommunications solution provider, Telarus, began a review and found some fundamental issues with the existing smart building design such as a high number of single points of failure and no plans for redundancy for Internet access into the building.

The original plan called for all voice services to be delivered via a third party IP Centrex platform. But there was no capability to enable IP QoS, residential wireless access points instead of business grade devices, no support for PoE, and inadequate power protection.

Moreover, Telarus managing director, Jules Rumsey, said a number of small unmanaged UPS devices were going to be used for core equipment.

"This would result in poor efficiency and fault tolerance and the use of unmanaged equipment would mean a complete lack of visibility," Rumsey said adding that the site also had poorly configured cabling as well as a significant amount of metallic and reflective materials which can create wireless issues.

Budget restraints also reduced the number of Ethernet switches and the ability to deploy a centralised wireless network.

To allow individual sites in the building to have their own phone system, a Mitel 3300 IP phone solution was deployed to provide PABX services to tenants.

The system allows for seamless IP networking across multiple sites, robust switching, hot-desking, and support for touch-of-a-button, drag and drop video and audio conferencing. Trunking can also be done via analogue PSTN, PRA/ISDN, and SIP.

The solution included an MX expandable controller to allow for up to 1400 VoIP users, and an ASU II to provide analogue lines for faxes and handsets.

Bwired also runs a primary rate ISDN service to provide connectivity to the PSTN, which Telarus installed with five lines - two for emergency use, and one each for an out-of-band modem, a business centre fax, and backup line.

Fault-tolerant Internet access to the site was provided via a primary Ethernet service with a secondary SHDSL service. Both will be terminated on a Cisco 1841 supplied and managed by Telarus with two fast Ethernet ports and an SHDSL WIC.

Rumsey said wireless access within each of the suites is being provided via the Mitel wireless base which clips on underneath the handset in favour of the standard base.

A FortiGate 200A firewall is being used for security and as threats increase a second firewall will be installed to provide a high availability configuration.

Bwired managing director, Sam Saltis, is expecting a takeup rate of 80 percent for the new service.
