## Highlights

Technological advances have led to an increasing convergence of previously separate networks used to transmit voice and data communications. While the benefits of this convergence are enormous, such interconnectivity also poses significant challenges to our nation's ability to respond to major disruptions. Two operations centers--managed by the Department of Homeland Security's (DHS) National Communications System and National Cyber Security Division--plan for and monitor disruptions on voice and data networks. In September 2007, a DHS expert task force made three recommendations toward establishing an integrated operations center that the department agreed to adopt. To determine the status of efforts to establish an integrated center, GAO reviewed documentation, interviewed relevant DHS and private sector officials, and reviewed laws and policies to identify DHS's responsibilities in addressing convergence.
