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.

One of the system is actually quite old in the sense that it is a direct descendant to what Alexander Graham Bell had originally developed back in the day. This would be the landline system. It is still being used in both offices and residences, and its use continues to be very widespread. This is an analog service with 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.

The switches are also set in place already. This will create a private circuit for just about every call that takes place. Many call it the public switched telephone network because of that, sometimes just PSTN. This has been made available for several years and has withstood every other new variant that arrived since then. The use has not been affected in any significantly negative way whatsoever.

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.

Some of these networks are national. However, there are a few international ones and the best part is that brand new technologies are continuously being developed. 3G supports not just cell phones, but also smartphones, netbook computers and even wireless modem aircards.

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.
