Abstract :
Many of the independent telephone companies in the United States need an economical means of obtaining short-distance carrier circuits. The 3-channel stackable system, while coordinating with other systems of conventional channel allocation, may be installed as service demand requires, one channel at a time, each channel independent of the others.
