The original Datenklo or CCC-Modem was an acoustic couplermodem in the early 1980s for which the Chaos Computer Club made plans and schematics available.[1] The moniker 'loo' refers to an ingenious idea in the construction of the device: The use of rubber cuffs, commonly available as plumbing supplies, to connect the audio transducers to a normal telephone receiver.
The Datenklo name was subsequently repurposed to describe the use of rented portable toilet cubicles to host communications infrastructure at hacker camps:[2]Шаблон:Blockquote
Connectivity
The Datenklo provides a temporary wiring closet for the networking equipment required to deliver pervasive connectivity to hacker camp attendees:[3]Шаблон:Blockquote
Datenklos are interconnected to create the site network, with hacker camp attendees asked to bring their own cables if they would like a wired connection to their tent:[4]Шаблон:Blockquote
Hacker camps are generally organized and run by volunteers known as angels, and the Network Operation Centre angels not only create the network as part of site build-up and tear it down afterwards, but also connect attendees' cables to the switches in the Datenklo:[4]Шаблон:Blockquote
Whilst wireless networking and Internet protocols have become the norm for voice and data communication, the Datenklo provides hacker camp attendees with the opportunity to build and learn about Plain Old Telephone Service (POTS), turning the Datenklo into a "phone box" of sorts:[6]Шаблон:Blockquote
