T-1 Carrier AKA T-carrier

---

Technology developed by Ma Bell at Bell Laboratories, in part to circumvent the infiltration into the multi-frequency automation by phone hackers, or phreaks. T-carriers marked the first use of digitalization in commercial communication technology and provided exponentially greater speeds of transmission data via the translation and reduction (and subsequent reconstitution) of audio signals into binary bits via codec. T-1 technology could not be operated via Plane Old Telephone Service Lines (POTS) and required the installation of massive amounts of new hardware. T-1 lines were able to transmit data along with audio and quickly became the preferred conduit for hi-speed infiltration into corporate and governmental cyberspace by the Legion of Doom, Masters of Deception, and extended @Cafe hacking communities.
