Cox Communications has named former BellSouth and Sprint executive Don Hallacy as its interim chief technology officer.

Hallacy will lead Cox's technology organization until a permanent CTO is named. Hallacy's appointment was announced internally yesterday at Cox.

"Hallacy is a seasoned business leader with nearly 30 years of experience successfully leading technology organizations, from start-ups to large companies," Cox said in a statement. "Mr. Hallacy brings a wealth of strategic and practical experience to our business, where he will serve as a member of the senior team with full responsibility for running the technology organization."

In June, Cox announced that executive vice president and chief technology officer Scott Hatfield had resigned from his positions at Cox. At the time, Cox said that Percy Kirk, senior vice president and general manager of Cox Oklahoma, would handle some of Hatfield's former duties.

Hallacy has extensive experience in the telecommunications industry, including with phone and Internet services. Last week, Cox announced the commercial availability of its residential 3G network, which is currently being provisioned through Sprint until Cox's network is completed, in three markets.

Hallacy joined the former Atlanta-based BellSouth Corp. in 2002 as the chief information officer of the communications group and president and chief operating officer of the BellSouth Technology Group.

While at BellSouth, he directed all domestic wireline information systems, including ordering, billing, provisioning, network operational support and customer care for both wireline and broadband product lines. Hallacy held this position until 2007 when he began his own technology consulting practice.

In 1992, Hallacy joined Sprint as director of application development and held several roles of increasing responsibility before being named vice president of next-generation product and application management in 1997.

Hallacy left Sprint in 1999 to become CEO of Atlanta-based start-up Eltrax Systems. Eltrax was a full-service application services provider that planned, built and ran the technology that high-growth businesses required to serve their internal and external customers.

In 2000, Hallacy returned to Sprint as the president of Sprint Internet Service, where he built an Internet services business with product offerings, marketing and sales programs, operations, and engineering that grew to $1 billion in revenue with 2,000 employees. Within a year, he assumed the responsibility as president of technology services, directing 12,000 network and IT professionals that brought to market a leading-edge network platform in support of Sprint's ION initiative.

Hallacy began his career at Arthur Anderson & Co. in 1982 and also worked for Information Consulting Group and McKinsey & Co. 

Hallacy resides in Atlanta, which is where Cox is headquartered. He has served on the boards of Eltrax, Iridium North America and New Focus.
