Amdocs said Comcast has signed a multi-year extension of its software license and services agreements. The vendor said Comcast is using various offerings in the Amdocs CES (customer experience systems) portfolio.

Amdocs CEO Eli Gelman said: "This deal increases our visibility with a highly strategic customer and creates a stronger foundation for the evolution of our long-term relationship. Additionally, we are engaging with Comcast on other new initiatives within our CES portfolio."

The comment was made in the company's first-quarter conference call with financial analysts, as transcribed by Seeking Alpha.

For its first fiscal quarter of 2012, ended Dec. 31, Amdocs reported revenue was $807 million, down 0.6 percent sequentially from the fourth fiscal quarter of 2011 but up 4.1 percent compared to its 2011 first quarter.

Net income was $111.3 million, compared with $99.8 million in the similar quarter a year ago.

In his statement from the company's first-quarter financials announcement, Gelman said: "During the quarter, we signed several key strategic wins, including the agreement with Comcast announced today, and three deals in Latin America. These wins are strong evidence that the investment decisions we made over the last year were focused in the right areas and are supporting exciting new activities. First, the cable industry continues to progress forward with gradual transformation. The multi-year agreement with Comcast demonstrates that Amdocs is partnering with leading cable operators to realize their vision. Additionally, the new business in Latin America further establishes Amdocs as a leader in providing next-generation customer experience systems in one of the fastest-growing emerging markets."

The company said it is currently working with AT&T, another of its customers, as AT&T refocuses its IT and other priorities.
