Popis: | The rapid expansion of suburban and small urban communities has created such a demand for increased communication facilities that the telephone companies are hard pressed to supply the requirements. They find themselves required to supply not only house phones, business phones, etc., but new subscriber lines, new extended area trunks, and new toll trunks in order to handle the increased load. |
