Wayne Township, N.J., turned the benefits its mayor found in a consolidation of his home Internet and phone services into a money-saving solution for the municipality.
"My theory was that if I could cut my bill in half at my house, perhaps we could utilize the same type of technology here at Town Hall and save money," said Mayor Chris Vergano.
He presented the idea at a township meeting and said he received skeptical looks from others in the room, but the Division of Information Technologies took the concept seriously. The division studied the idea and told Vergano that the township could save a bundle of money by consolidating its Internet and phone services. It turned out to be more than $52,000 annually.
"Anytime we can find new and creative ways to save money, we're willing to take a look at it," Vergano said, "and that's exactly what we did here."
The project began with an ordinary RFP, said Scott Pasternak, technology director of the township. He chose Optimum Lightpath to provide the consolidated service. The company already provided the township's Internet service, which eased the transition. "When we did our consolidation, we first tried to evaluate our existing vendors to minimize our financial impact by reutilizing our infrastructure," Pasternak said. "Optimum Lightpath did make some hardware changes, but there was no financial cash outlay to Wayne Township."
The new service provides Internet and telephone communications over a single connection. Although this sounds like VoIP, it's different from an infrastructure standpoint. In a typical VoIP deployment, voice communications are sent and received via the Internet, replacing an analog phone line. Standard voice over Internet protocol (VoIP) requires a broadband connection, specialized phones (or land line phones connected to a VoIP adapter), and in-house network infrastructure optimized to ensure that data packets are delivered efficiently.
Pasternak said Wayne Township's voice and Internet communications are run through a metropolitan Ethernet line, which allowed the internal infrastructure to remain the same, while still providing a data link for the communications to share. Using the Ethernet line allowed the township to keep its existing technology and avoid the network overhaul that VoIP typically requires. All calls are directed through a single hub.
Pasternak said the township is moving toward using VoIP telephone sets and evolving the system slowly instead of doing an enterprisewide upgrade all at once. "In this manner, we are easing into VoIP as we capitalize on past investments to ensure our ROI," he said.
The consolidation began in the second quarter of 2008. Pasternak estimated that it took the township six weeks to complete the project, from the initial investigation to being up-and-running.
The IT division used 3 megabits of the 10-megabit metro Ethernet line for the primary rate interface (PRI), which is a telecommunication standard used for integrated services on a digital network in order to carry multiple voice and data transmissions. The township has two PRIs -- both of them have 23 channels, which means each PRI can handle 23 phone calls at a time.
The township's telephone sets are wired into three private branch exchanges (PBX). First, the IT division enabled IP-based trunking -- using an IP network to carry voice data -- between the PBXs so that all phone calls are directed to a single hub before they are sent or received. "Basically each phone system has an IP address," Pasternak said. "When we dial an internal extension or an external phone number, each phone system on our network sends the call to another PBX's appropriate IP address, and the calls are routed inside and out of our network."
