About Office of The Manager National Communications Sys
The Office of The Manager National Communications System was the administrative office of the National Communications System (NCS), a former U.S. government entity under the Department of Homeland Security responsible for national security and emergency preparedness (NS/EP) telecommunications. It coordinated interconnectivity and survivability of federal agency communications facilities, primarily serving government agencies rather than commercial consumers, businesses, or wholesale markets. The NCS was disbanded in 2012 and merged into the DHS Office of Emergency Communications; any associated OCN and number blocks likely represented government-assigned resources rather than a commercial carrier operation.
