The Variants 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 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.

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.

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 networks are operating on a national scale. Others are even operating internationally, and one of the best parts is that new technologies are frequently being developed. 3G is known support not only cell phones, but smartphones as well, together with netbook computers and 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.
