|High capacity cable that runs from the exchange to the
street cabinet. This is called the "E" side cable.
Run in a continuous length if possible to avoid joints.
As this cable will be pressurised and is an expensive cable, the less joints means literally no maintenance. It was found that if the cable leaked, the pressure would generally stop any water ingress until the leak was repaired.
In the early days of the Telephone, there was no such thing as multi-core cable and customers were fed with open wires from the exchange to the premises. Click here for more details.
