The Different Types Of Phone Systems

By Leanne Goff


There are various types of phones and corresponding types of phone systems Chicago. For the sake of information, there are around three primary types that can be further discussed in much greater detail and clarity. One would be the plain old telephone service, another would be the internet protocol phones and lastly, there are the cellular phones.

The plain old telephone service is also commonly known as POTS. It relatively old and it is directly descended from the same system that was developed by Alexander Graham Bell. This is commonly known as the landline, which most residential and commercial structures still make use of. It is also an analog service that has copper wiring.

There are multiple advantages that come with this particular variant. Some of these advantages include the use of standardized equipment as well as having predictable sound quality. Due to the direct connection it has to the central office, there is actually no need for its capacity to be shared with others who may want to make use of it as well.

All of the switches are already set in place. This creates private circuits for every phone call that is made. Because of that, many refer to it as Public Switched Telephone Network or PSTN. This is something that has been available and used for many decades, even after other variations have risen with all the improvements of technology. Its use has not yet falter in a significant manner.

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 that similarity, there are notable differences as well. A primary one would be the fact that the cellular variety makes use of radio frequencies as opposed to copper wire. Though these things first started out as mobile voice networks exclusively, they are not capable of carrying both data and voice.

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 using a single line for internet and telephone services both. This is a way for people to save up on money. Using integrated T1 lines, instead of setting up for voice or data, it would be a way to handle both. These are a few that that can be expected from varying phone systems Chicago.
