Commercial Telephone Systems

The base change with a single invention has brought the world is exactly the phone. Talking to loved ones far without effort and the effort to comfort her house is in the interest of this invention. In this modern world of mobile phones and Internet telephony, the fundamental change in society that have taken place with the invention of the telephone is taken for granted.

Within days of the old school, children have learned to tie two cans together using a thin wire and holding them apart for its flow from one end to another. This is a basic phone is seen in the Flintstones cartoons, but the real need for electricity and components.

It's a completely different system used on ships in the form of long pipes in the deck of the ship could be transported to the engine room. The electric telegraph was invented in the 1800s and was constantly carrying messages of all kinds. There was always a desire to improve the telegraph. Knowledge of sound waves through the education of deaf students Alexander Graham Bell invented the idea of a phone.

Bell was recognized as a gentle man and an inventor of the telephone. He almost lost the honor as Bell and Elisha Gray, another leading inventor has applied for patent for the telephone on the same day, February 14, 1876. Unfortunately, Bell's counsel and secretary of the Patent Office who had served in the Civil War and conspired for the registration of patents of Bell first. The patent examiner rejected the treatment when he realized that both applications were similar until they can be demonstrated. Bell has demonstrated the technique devised by Gray and obtained the patent. According to historians, Gray would have considered the inventor of the telephone if Bell had not demonstrated first.

Only a year after Bell's patent was registered, the techniques of Alexander Graham Bell and Thomas Watson directly led to the first commercial telephone services. Other leading scientists before Johann Reis Bell as Germany and Italy Antonio Meucci also showed prototypes of the phone, but their techniques are not very advanced.

The citizens of Boston have benefited for the first time in 1877 with the installation of the first telephone. Telephone switchboards were soon invented to allow subscribers to talk to any telephone connected to the same set of telephone lines. The first entered service in 1878 in New Haven. After the first three years of business phones, the U.S. boasted about thousands of phones. With the invention of the telephone, customers need a way to effectively connect with each other without connecting to an operator.

Early telephone exchanges were based on site and a subscriber can not speak to another subscriber on their own exchange by asking an operator to make the call. Long distance calls can be placed at home. An appointment was needed with the telephone capable of transmitting over distances of wire.

The actual phone device used in the house has grown considerably in the 1920s when Western Electric developed a phone that consisted of a combination that includes a headset and microphone. This allowed customers to talk while moving for the first time. The Bell Model 102 was the first development of this type of phone still popular today.

Phones did not change significantly after 1930 until the introduction of digital phones and exchanges in the 1960s. In 2005, the mobile phone connections in many developed countries eclipsed fixed line connections.
