Follow @ryderskull88

Telephones are an extremely interesting invention of Alexander Graham Bell. It was perhaps the first invention in the field of communication. After his invention till today with the advancement of technology telephone services are in the path of improvement. Latest telephone models are produced today to draw the attention of the customers. Different types of phone services are available today in the market.

Previously to have a telephone at home was a luxurious affair, but now it is a common affair at any every home. Land phone is one of the traditional phone services. It was in the hike of the market in the olden times. But today these traditional phones are being replaced by newly invented and highly sophisticated phone services. This is the main reason why traditional land line services are declining today. But land phones still exists today because there are some staunch believers that land lines are the most trust worthy services and do not want to give up this service.

Land line phones are mainly replaced after the invention of mobile phones. Land phones are not portable and involve wire connections while mobile phones are small and sleek, wireless and usually run through satellites, for these reasons mobile phones can be carried easily from one place to another. Mobile phones are now common everywhere. It is mainly famous among the youngsters. By taking advantage of their likings the mobile companies in order to promote their business are introducing fashionable, trendy and colorful mobile sets involving many exciting features which automatically become eye catching among the teens. Mobile service companies are seen in hard competition with each other and so they are providing interesting offers and packages for enjoying low call rates both local and long distant calls. Now internet is also possible through mobiles. So it can be seen that when mobile phones are providing such exciting services then why people will stick to land phones.


Digital phone services are another type of phone service. Many traditional TV or video companies are providing voice services over their networks. The main advantage of this type of service is that a single company serves multiple purposes like scheduling maintenance, scheduling installation, paying of monthly bills and many more. You will get this type of phone service you will have to contact your nearest cable operator of your locality.

Next is Internet phone service. If you already have a high speed internet service or if you are ready to purchase a service from an internet service provider then you can enjoy low rates of monthly calls valid for both local and distant calls that are offered by internet phone service providers generally called VoIP then this is the right service. For availing better services contact the service provider of your locality. 


Different types of home phone services are discussed in this article for your better assessment and for your better understanding. But the service providers cannot select a service for you because it is you to select a service. This article can only assist you to select.

History of The Telephone Line

Follow @ryderskull88
The telephone was famously invented by Alexander Graham Bell in the US during the 19th century, with the first call made over just 100 feet (30.5 metres) on the 14th of February, 1876. In the subsequent years a global industry has developed around this type of technology, with the humble telephone line still going strong to this day despite competition from emerging wireless services.

Here is a quick overview of the history of the telephone line from its early establishment to its modern applications, which should hopefully indicate just why it was such an important technological advance and how it changed the world.


Within two years of the first telephone call being made, Bell's patents were used to set up a company in the UK, backed by the then not insubstantial investment of £100,000. 150 telephone lines were quickly rolled out in London, with each line able to support a maximum of eight users simultaneously.


Further telephone exchanges were developed in the UK until in 1879 there were 200 subscribers in London, with lines leading across the country to Sheffield, Manchester and even Edinburgh. A rival company founded on the patents registered by Thomas Edison was also established in this year, undercutting the price of Bell's service by a significant margin in order to win over British customers.
The technology powering telephone lines was continually developed over the years, but it was in 1922 that things really got going when electro-mechanical technology designed by Almon B Strowger of the US became widely adopted to help automate the process. For the next seven decades or so, the UK's exchanges used a variant of this hardware in order to route calls.

By the mid-1980s, BT had become a private company and it began to look to digital technology to replace the analogue signals which had been carried by telephone lines for so many years. Investments of over £20 billion were made to update the UK's infrastructure. Despite this, it was not until 1995 that the final exchange working on Strowger's original design was closed, indicating the enduring nature of this set-up.


Using metallic cabling for telephone lines with analogue electrical signals transporting the audio information was not the only invention of Bell's which would go on to shape the world. As early as 1880, he was working with Sumner Tainter on something which they called the Photo-phone, which was essentially an early form of fiber-optic communication.

Fibre optics would remain impractical and largely unpatented for the transmission of digital data until 1966. The lower attenuation rates in fiber-optic cables compared to metallic equivalents made them desirable for long-distance signal transmission and the UK was home to the first fiber-optic data line during the mid 1980s when a 140Mbps connection was set up between Luton and Milton Keynes. This would pave the way for the proliferation of optical technology which we see today being rapidly rolled out to replace the original metallic infrastructure as data rates are increased.

The emergence of widespread broadband connectivity after the turn of the millennium, delivered either via traditional landlines or fiber-optic connections, eventually allowed more and more businesses and subscribers to access digital voice services. VoIP providers began to emerge in the middle of the 2000s, with companies such as Skype helping to introduce average consumers to the idea of making long-distance, IP-based calls between PCs rather than fixed-line handsets.

Today, a single fiber-optic connection or broadband-enabled telephone line can do the work of multiple older lines thanks to VoIP technology and the flexibility of the digital age. In spite of the growth of the mobile market, people still value telephone lines for their reliability and affordability.

Infographics: The Evolution of Traditional Telephone

The telephone colloquially referred to as a phone, is a telecommunications device that transmits and receives sounds, usually the human voice. Telephones are a point-to-point communication system whose most basic function is to allow two people separated by large distances to talk to each other. Developed in the mid-1870s by Alexander Graham Bell and others, the telephone has long been considered indispensable to businesses, households and governments, is now one of the most common appliances in the developed world. The word "telephone" has been adapted to many languages and is now recognized around the world.


All modern telephones have a microphone to speak into, an earphone (or 'speaker') which reproduces the voice of the other person, a ringer which makes a sound to alert the owner when a call is coming in, and a keypad (or on older phones a telephone dial) to enter the telephone number of the telephone to be called. The microphone and earphone are usually built into a handset which is held up to the face to talk. The keypad may be part of the handset or of a base unit to which the handset would be connected. A landlines telephone is connected by a pair of wires to the telephone network, while a mobile phone (also called a cell phone) is portable and communicates with the telephone network by radio. A cordless telephone has a portable handset which communicates by radio with a base station connected by wire to the telephone network, and can only be used within a limited range of the base station.
