The Digital Collection System Network (DCSNet) is the Federal Bureau of Investigation (FBI)'s point-and-click surveillance system that can perform instant wiretaps on almost any telecommunications device in the United States.[1]
It allows access to cellphone, landline, SMS communications anywhere in the US from a point-and-click interface. It runs on a fiber-optic backbone that is separate from the Internet.[2] It is intended to increase agent productivity through workflow modeling, allowing for the routing of intercepts for translation or analysis with only a few clicks. The DCSNet real-time intelligence data intercept has the capability to record, review and playback intercepted material in real-time.[1]
The DCSNet systems operate on a virtual private network parallel to the public Internet, with services provided at least for some time by the Sprint Peerless IP network.[3]
Much of the information available on this system has come from the results of Freedom of Information Act (FOIA) requests made by the Electronic Frontier Foundation (EFF).[4]
