Clearfield Co. 911 Center Upgrade 6:20 pm On Tuesday, the Clearfield County Commissioners approved the 911 Letter of Engagement with Commtech which officials said is the provider of Next Generation 911 services for the state. Jeremy Ruffner, 911 Coordinator for Clearfield County, said these upgrades will impact Northern Tier counties including Clearfield, Elk, Cameron and Jefferson Counties. “This upgrade would create a private fiber network and would connect to the state’s heavy net system giving the counties in the Northern Tier a much more secure connection for things like CAD and telephone services,” said Ruffner. CAD, known as “computerized dispatch,” is information that allows dispatchers to know who is calling and where responders should respond to.
