Sorting out the Baby Bells' strategies.

After months of uncertainty, the seven regional Bell operating companies have divided into two camps: those that provide only the infrastructure for health care networks, and those that offer infrastructure along with other networking features, such as systems integration and central data repositories. In their quest for health care market share, the Bells face a number of obstacles. For example, they can't provide long-distance service, and they face restrictive rate regulations. In addition, increased interest in cable TV and wireless communication ventures has led some of the Bells to downsize their health care ambitions.
