The Tetrahedral-Octahedral Truss

  title={The Tetrahedral-Octahedral Truss},
  author={Henry Crapo},
The clock pulse supply in a PCM time-division having modular switching facilities within the switching centers is produced by a clock generator associated with the module which steps a time-slot counter that counts in a time sequence, remains stopped, or is backspaced such that it is capable of accessing the main store of the center as well as the address memories of said module.
