The Different Types Of Phone Systems

By Leanne Goff


When it comes to phones, there are many models and variants and the phone systems Chicago to match them. This is something that not everyone is aware of, and there are quite a few that are actually very interested in learning about this. One of the systems utilized today is the plain old telephone variation. Another is internet protocol and then there is cellular phone.

The landline system that is still being widely utilized in households and offices today are actually part of the POTS or the plain old telephone service. This is the analog service that has copper wiring. It can be said to be a direct descendant to the system that was originally developed by Alexander Graham Bell.

There are a lot of advantages when it comes to this specific variant. Such advantages include, but is not limited to the utilization of standardized equipment and sound quality that is considered to be predictable. Because of the central office connection that it possesses, there is virtually no need for the sharing of its capacity to others.

The switches here are normally already in place. This will hereby create a private circuit for each and every phone call. Because of that, it is also referred to by many as PSTN or the Public Switched Telephone Network. It has been widely used for decades and even with the rise of other variants as technology improves, its usage has yet to falter in any major way.

The second type is utilized heavily by cellular phones. Companies can occasionally have networks that are exclusive to them. Simultaneously, what they have will vary in terms of the type and how far off their technology is. It is comparable to POTS, since it is a full duplex system. That means those on both lines may talk and listen simultaneously.

Despite its similarity, there also exists a notable difference. Such a difference comes in the form of radio frequencies, which is utilized in this variation rather than copper wire. These things started out exclusively as a mobile voice network, they are basically incapable of carrying voice and data at the same time.

There are quite a few networks that operate nationally. Some even do so on an international stage. The best thing about all of this is that technology is in a state of flux. At some point, a new standard will be established and the cycle will continue to evolve for as long as possible. 3G can support wireless modem aircards and netbook computers, not just cell and smartphones.

Internet protocol, or IP, is also referred to as voice over internet protocol, or VoIP. This yet another version that is used in modern times. This particular service usually piggy backs on the existing internet connections, either DSL broadband or perhaps cable service. A device that is known as the analog telephone adapter is usually the go between that will connect phones to the router or the modem.

This system can be set up with the utilization of just one line for both telephone and internet services. This is how some people save up on expenses. Rather than set up for data or voice, T1 lines can be used as a method of handling both. These are some information that concerns phone systems Chicago.
