Alltel Picks Calix DSLAMs

PETALUMA, Calif. -- Calix today announced that ALLTEL [NYSE: AT] has selected the Calix C7 ultra-broadband loop carrier (UBLC) for deployment in select central office DSLAM applications. Already deployed in the ALLTEL outside plant and recently named the Q1/2004 global BLC market share leader by Infonetics Research, the Calix C7 is one of the only UBLCs also able to operate as a high density, high capacity central office DSLAM. Calix has been a supplier to ALLTEL, which operates 3.2 million access lines, since early 2002, providing remote terminal UBLCs delivering voice and data services to business and residential subscribers.

"We already use the Calix C7 platform for DLC applications. The flexibility and capacity of the Calix platform also make the C7 ideal as one of our central office DSLAM platforms," stated Shannon Leach, vice president of network planning with Little Rock, Arkansas based ALLTEL. "This allows us to manage one platform for dual applications, a big plus. Over the last two years Calix has proven itself to be a very responsive and reliable supplier to ALLTEL."
