Times have certainly changed in more ways than just the one and nowadays there are various sorts of telephones and comparable kinds of telephone systems out there for anybody to make good use of.

The three major ones are the old style land line telephone service, the more recent Internet Protocol phones and the extremely popular cell phones which have become a must for practically everybody during these times. Let’s take a look at all of them:

Land Line

• The landline telephone system which was used for most of the 20^th century are part of what is known as the “Plain Old Telephone Service” (POTS), and are an analogue system with copper wiring that comes down to us as a direct descendant of the original telephone system devised by the great Scotsman, Alexander Graham Bell.

• The benefits of this type of service involveregulated equipment, particular sound quality, and because of a direct connection, no need to experience the system’s capability with anybody else. Due to switches being in place, this created a private circuit for every phone call made and is known as the Public Switched Telephone Network (PSTN).

VoIP

• This is known IP, and more recent, and is growing increasingly popular, Also known as Voice over Internet Protocol (VoIP), is yet another kind of telephone service that has come into use now in the 21st century. This new prominent service,simply rides on existing Internet connections, be it cable service or DSL broadband.

• A mechanism called an Analog Telephone Adaptor works as the go between which connects whatever type of phone you happen to have with either the broadband modem or the router. In matters of modern business the use of a VoIP phone from Birchills, is certainly a great way of making your company move forward.

• An IP system can be created with a single line for both an Internet and a telephone service, which many people are starting to use to its ease of use and cost savings. With an Integrated T1 line, rather than being put up for voice or data, the T1 line can administer both. With Dynamic T1, the line has the capability of appointing bandwidth as required, given the present usage.

Cell Phone

• And of course the amazing cell phone, a simple machine that many people just can’t do without these days! Nowadays, with many phone companies providing their very own networks working alongside variousmeans of technology, cellular telephones are now fully duplex devices, and a user can receive one or more calls at the same time.
• Although cell networks started as mobile voice networks only, they can now carry both sound and data. A number of networks are only national, while the others are international, and new types of technology are always in development. The networks known as 4G support everything from cell phones to notebook/laptop computers, smartphones, and wireless modem air-cards.

Telephone systems have certainly come a long way recently and it makes you wonder just where it will go in the future!
