New York builds in network reliability.

Government agencies and businesses planning to build advanced telecomm networks are getting some encouraging news from New York.

The New York State Offices of General Services and the Securities Industry Association (SIA) report that their new networks, known as Empire Net and the Securities Industry Digital Network (SIDN), are delivering all the benefits of advanced services with greater reliability at a substantial cost savings.

General Services, which manages New York's lottery network, and the SIA, a large consortium of Wall Street securities firms, attribute much of their networks' success to New York Telephone.

"The telephone company is providing products and services to meet the customers' schedules, not the other way around," says Roger Quinby, deputy commissioner of New York State's Offices of General Services. Empire Network is a huge statewide voice and data communications system. When it went on line in September 1991, Empire Net changed the way 29 state agencies communicate.

The network, the largest of its kind in the country, is made up of 153 nodes of intelligent multiplexers, 453 T1 trunks of interconnected nodes and more than 8,000 tail circuits. The system can be centrally monitored and transmits data at speeds of 1.2 to 384 kb/s. It blends applications and nearly 100% reliability to save the customer a lot of money.

Quinby estimated the network has saved New York taxpayers more than $12 million.

"We're looking at one-fourth to one-third third the number of troubles in the State Lottery (with 6,800 agents) portion of the network versus the old network," said Quinby.

In lower Manhattan, the network created for the SIA resulted in the first-ever voice and data network linking a consortium of securities firms with the New York and American Stock changes. The network was such a hit with its original 16 member firms that the system has grown to include about 90 companies.

According to Pam Goodbody, SIA's vice president of telecomm and information, reliable service is more important than saving money. In fact, the original mandate to New York Telephone was simply to provide improved service.

New York Telephone came back with a flexible network that expands or contracts as business needs dictate without incurring changes for every move.

Another important design element was instant rerouting should disaster strike. The consortium is linked to a redundant backbone network with every T3 on a one-to-one backup system representing a combination of 28 T1s.

Provisioning circuits within 24 hours of a customer's request is another key feature. The system can also be monitored and manipulated to avoid problems before they occur.

But the money saved on this system should not be overlooked. The savings began at one-third over the previous vendor, Goodbody says. But it has now grown to about 50% because the price under the previous arrangement would have increased over time, while now they are locked is under SIA's five-year agreement with the telco.

"It has been a very rewarding and valuable deal," Goodbody says.

It took two years to conceptualize, design and implement these networks, all but consuming the lives of the 600 employees that put them together.

Phil Miller runs the control center of Empire Net and the SIDN and draws his paycheck from New York Telephone.

"We're seeing a lot of companies looking around for someone to build and maintain their private networks, and a lot of them are coming to us," Miller says.

While the two networks were sound in theory, Miller concedes, "It was a pleasant surprise to see that we were right and they performed as expected, particularly because of their uniqueness and complexity in design."
