Telephone CableThere is no doubt about it, the telephone is one of the most important inventions that the world has ever seen. Telephone has been around for years and is incredibly important when it comes to keeping in contact with loved ones. Continuing with communication, telephone has allowed us to communicate lightning fast from other sides of the world and we now no longer need to send letters to quickly send a message.
Within telephone technology lies the telephone cable, which can be seen hanging from streets in the USA as well as worldwide. These are the vital source that allows connections to be made from all over the world and they have been developed over a long period of time. Without them, telephone would not be what it is today.
Most of you may not know how a telephone cable works and how they send data to connect calls. If you’re interested in what they do and how they work, we have put together a short article explaining everything. If you’re looking to find out more, continue to read on.
What is a Telephone Cable?Although it may seem very complicated, a telephone cable is actually easy to understand. They may look like spaghetti when you’re walking down the street, but they are actually all individual phone numbers. Telephone wires tend to be designated a specific household, which helps with the billing purposes of telephone. This means that all houses have their own unique telephone cable that runs from their jack point to the overhead poles.
The purpose of a telephone cable is to deliver a landline connection to a user. This connection is distributed via overhead cables that all relay back to the public switched telephone network. In all houses and small buildings, there is a junction box, which acts the middle man between the overhead telephone cables (local telephone exchange) and your own personal telephone cable. This junction box configures the incoming cables to your subscribed telephone service. The wires going from the box and the exchange are known as the local loop.
How are Telephone Cables Wired?First of all, telephone cables are typically copper to help with conduction. However, aluminum has been used before. In most modern US homes, the telephones cables are wired with 6 position modular-jacks with 4 conductors (6P4C) to the house’s junction box.
Those wires are often linked back to the overhead cables are the telephone exchange. The actual cables connecting to the overhead cables are sometimes RJ45s. In some places, telephone lines may even run underground, carrying both analog and digital signals. In older houses, they’ll be a 4 conductor cable in the walls using the older color codes used with the Bell system.
