Charter Communications Now Using Full Capabilities of CSG Care Express

ENGLEWOOD, Colo. (Oct. 11, 2005) Leading global customer care and billing solutions provider CSG Systems (Nasdaq: CSGS) today announced that Charter Communications, Inc. ("Charter"), a broadband communications company, is now actively using all of the capabilities of CSG Care Express to deliver more customer care options to its customers.

Charter provides broadband services to the home, including digital cable television, high-speed Internet and phone service to over six million customers nationwide. To provide a higher quality of customer service and offer more convenient options for customer care, Charter began offering CSG Care Express capabilities to its customers in 2002 and has continued to add additional components of the solution over time to further build out its online customer care services.

CSG Care Express allows customers to view, manage and pay bills over the Internet and virtually eliminates manual processes carried out by customer service representatives when taking orders and upgrading services. Charter is actively using all of the components of Care Express, including Electronic Bill Presentment and Payment, Self-Care, and Consolidator, the newest module that allows customers to pay bills from their broadband service provider through their choice of over 1,500 banks and financial services web sites.

Today, more than 300,000 Charter customers use Care Express to manage their accounts online.

"Delivering the most advanced services to our customers and making it easy for them to do business with us is among our top priorities," said Charter Vice President of Information Technology Judith Howard. "By allowing our customers to maintain their account information, change service packages and pay their monthly bill through Charter's Web site or financial Web sites, CSG Care Express helps us achieve those goals."

"As broadband operators like Charter roll out voice and other advanced services, the ability to serve the customer through a variety of channels becomes critical," said Dwayne Ruffin, Vice President of Product Management for Broadband Services at CSG. "Customer self-care is not only a cost-saving measure, it also gives consumers what they want - an easy way to interact with their provider on their terms."
