Abstract :
A NEW telegraph carrier terminal has been developed to meet the ever-increasing demand for telegraph communication facilities. The terminal is designed to meet the frequency spectrum requirements for 12-channel telegraph systems.1 These standards were set up to allow the telegraph communication systems of the U. S. Army, Navy, and Air Force and many existing commercial systems to be integrated for joint use in the interest of national defense.
