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.

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 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 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.

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.

It may be similar in that way, but differences are also present. The main difference comes in the form of what they use. In this one, radio frequencies are utilized instead of just copper wire. They are incapable of carrying data and voice simultaneously and they also started out as an exclusive mobile voice network.

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.

IP systems may be set up with single lines for both telephone and internet services, which can serve as a way to save money. With the use of an integrated T1 line, rather than setting up for data or voice, such a line would be able to handle both. And that is what one can expect from the different phone systems Chicago.
