An early example of an underground long distance (trunk) telephone cable. The earliest telephone cables were carried overhead, and before long the skies in urban areas were filled with wires as a vast network of aerial cables radiated from exchanges. These were carried by huge distribution poles which often collapsed under the weight of the heavy copper cable. The first significant long distance underground cable was laid between London and Birmingham in 1898.
