to Local Companies Like KeySpan and the Securities Industry

Automation Corporation(R)

The Center for Advanced Technology in Telecommunications (CATT) at Polytechnic University announced its 20th anniversary as a research center and a partner of local businesses.

For more than 20 years, CATT has partnered with local businesses like KeySpan Corporation and Securities Industry Automation Corporation (SIAC)(R) to meet their evolving needs through its research, consulting, education and business outreach efforts.

CATT has helped implement enabling new network and telecommunication technology for KeySpan and SIAC that already has resulted in cost savings, improved efficiencies and higher productivity in the companies' operations.

The research center helped KeySpan to develop its Customer Service Hand-held Computer Work Management system, and modernized its Engineering Mapping system. The advancements have contributed to significant cost-savings for KeySpan and its customers.

CATT assisted SIAC, the technology subsidiary of the New York Stock Exchange and the American Stock Exchange, in testing the reliability and performance of the company's innovative Secure Financial Transaction Infrastructure (SFTI), a highly secure and resilient communications infrastructure for the financial industry. SFTI makes the securities industry network less vulnerable and more resistant to man-made and natural disasters.

"KeySpan has had a long-standing and mutually beneficial relationship with Polytechnic University," said Pam Adamo, KeySpan vice president of Community Affairs. "Our partnership with Polytechnic's Center for Advanced Technology in Telecommunication has provided valuable research and expertise that has translated into quantifiable benefits and savings for our customers."

"CATT has been a key partner for SIAC for more than 10 years in terms of network resiliency research, and in providing continuing education programs for our employees," said Andrew Bach, vice president for SFTI at SIAC. "We've also hired many graduates from CATT and find its technical curriculum an excellent foundation for employees."

"CATT is pleased to be a key research partner of these two highly successful companies based in New York's MetroTech Center area," said Shivendra Panwar, director of CATT. "CATT's main goal is to provide the innovative research needed to help New York companies grow and prosper. These two companies are just two examples of our accomplishment of this goal."

CATT is a research center located at the Polytechnic University campus in Brooklyn, NY. The center is supported by New York State Office of Science, Technology and Academic Research (NYSTAR). CATT business partners have participated in joint research, gained access to state-of-the-art facilities and a team of experts who understand how to turn technological breakthroughs into commercially viable products and services.
