A company that purchased some of Nortel Networks’ assets two years ago is expanding in the Triangle.

New Jersey-based Avaya plans to add 135 jobs over the next four years as it invests $500,000 in expanding and consolidating a supply chain center in Durham, officials said Monday.

Avaya bought the business enterprise business from bankrupt Nortel, which included part of the telecommunications company’s operations in the Triangle. As part of the expansion, the company will keep 193 existing jobs in Durham, as well as 111 elsewhere in North Carolina, officials said.

The new jobs will pay an average of $87.704 a year, plus benefits. Durham County’s average annual wage is $61,256.

The state Economic Investment Committee voted Monday to award a Job Development Investment Grant to Avaya. Under the JDIG, the company can receive part of the state withholding taxes from the new jobs for each of the eight years in which it meets annual performance targets, which could yield up to $1.69 million for the company.

“Avaya is committed to delivering the next generation of business communications, and this Video Center of Excellence will play a key role in the development of new collaboration technologies,” said Jim Chirico, executive vice president of Business Operations for Avaya. “The Job Development Investment Grant helps us strengthen operations of Avaya’s business that are absolutely critical to supporting our customers and to meeting their communication needs.”

Area community colleges also have agreed to provide $162,000 in training for Avaya’s workers.

North Carolina beat out New Jersey, Colorado and Canada for the Avaya expansion, state officials said.
