What reading level is American Telephone Practice book?
To quickly assess the difficulty of the text, read a short excerpt:
This allows the toll operators more space for making out tickets and does not hamper their work as, due to the comparatively small amount of equipment in a toll board, the "reach" is never great. In the face of the board and within the reach of each posi- tion is also usually provided a number of pigeon-holes in which the toll tickets and various other memoranda may be readily filed away.
Room is usually left on the key-shelf in the middle of each section for the mounting of an instrument known... as a calculagraph, this containing the time-stamping mechanism by which the elapsed time is recorded on the toll tickets. As one calculagraph is furnished for each section it is used by the two operators at that section, and such double use of the machine is not found to practically interfere with its proper working.
CHAPTER XXVII. DETAILS OF MULTIPLE SWITCH-BOARD APPARATUS.
THE designing of the various pieces of apparatus which form parts of that wonderful complex whole the modern multiple com- mon battery switch-board requires attention to an infinite number of details.
