We remember that the Automatic Electric Model 2 was the first integrated set to come on the market some 12 years before Western Electric introduced the series. This particular monophone Model 40 is included here because it is an integrated set and it competes with the WE series on stylistic and technical merits, something that cannot be said of the “clunky” AE Model 2.

The phone line A telephone is usually connected to the telephone exchange by about three miles 4. Although copper is a good conductor, it does have resistance. The resistance of No. In the United States, wire resistance is measured in Ohms per thousand feet; telephone companies describe loop length in kilofeet thousands of feet. In other parts of the world, wire resistance is usually expressed as Ohms per kilometer.
In the UK the maximum resistance should be no more than ohms although modern exchanges will work up to ohms. This can extended by the use of line drivers, which come in two types.
