The Variants Of Phone Systems

By Leanne Goff


There are several phone types as well as phone systems Chicago types. There may be some that are curious as to what these things are on a much deeper level. To those interested, there are at least three main types that may be discussed further. One is the internet protocol variant, another is the plain old telephone service and then there would be cellular phone systems.

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 actually several advantages to the use of this variant. Some of the advantages would include having standardized equipment and predictable sound quality. Because of its direct connection to the central office of the company, there exists no need to share its capacity with anyone else who may be in need of it.

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.

Another type is the one that is utilized by cellular phones. There are individual companies with networks that are just for them, and they also have different types and degrees of technology. Similar to the POTS, this is type that is basically a full duplex, which means that both people on the line may listen and talk to each other 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.

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.

IP or internet protocol is frequently known as VoIP or voice over internet protocol. This is just another version used nowadays. This service is known to piggy back on existing connections, such as cable service or DSL broadband. The analog telephone adapter is a device that serves as the go between that connects phones to routers or modems.

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.
