This system incorporates all of a TARDIS's communications devices, such as the Telepathic Circuits, Scanner, Voice Integrator, Telepathic Induction Circuits, Emergency Transceiver, Audio Units and internal communication systems. Using this system, a TARDIS can receive and translate any type of communications. Its computers can also process and intelligently sift though these transmissions looking for specified data. After materialization the TARDIS records all of a planet's radio signals and stores this information is filed in the Data-Bank.
