    Description

    Used item in good condition. Antique technology.
    The TSD-3600-E was an advanced telephone security device, developed by AT&T (USA) in 1992. It was based on the controversial Clipper Chip, forcing users to escrow their cryptographic keys. The TSD-3600 was a small white box that was connected between the handset and the phone.
    It only has two buttons and an LCD at the front, two sockets on the right (for connecting the phone) and a power connector at the rear.
    Also at the rear is a socket for a module, that adapts the TSD-3600 to the characteristics of the telephone's handset. A number of suitable modules was usually delivered with each phone and additional modules — for other handsets — could be ordered from the manufacturer. The TSD-3600-E box is inserted between the phone and its handset, by means of a short cable.
