The Journey To Modern Day Telephony

By Timothy J. Thomas


Telephony has changedconsiderably since the first telephones. Telephone technology has expanded from individual phones that were physically connected to each other, to a telephone exchange loops that connected local individuals. Other nearby areas were eventually connected to exchange loops via trunk lines. This allowed for more flexibility in communication. Services through telephone lines eventually grew to include both fax and data capabilities. The speed and capability to manage these lines was a huge limitation of this communication method.

Telephony soon began to transform after this limitation was realized and a new method was developed. This mode involved using a digitized line to bring better data quality to Internet users. Voice service was eventually brought to the same line that brings data networks. Both the Internet and the phone benefited fromfaster speeds and higher quality.

The term used to describe the use of telecommunications equipment in present days is digital telephony. The equipment of the past functioned using an analog signal rather than a digital signal. Not everyone has been able to transfer their phone service to a digital signal. Although the transferring process is going slow, it will eventually be completed. As a result, the implementation of digital signals allows for several distint methods of application.

For those who possess analog phones a converter box is accessible to allow signals to be converted from one form to another. But there are dedicated IP phones (Internet Protocol phones) that work without needing a translation. Rather than needing a regular phone jack, these phones will en able you to connect it through a router. IP phones also come in a wireless form, working on Wi-Fi networks rather than being stuck to just one location. A final possibility for digital voice involves using a computer as a phone, which also does not demand a conversion, but it does require a microphone, speakers and special software.

The final plan is to get all the users who subscribe to voice service on strictly digital telephony. This transition really just requires a good amount of time to get consumer and provider equipment updated. However, the switch to digital service is beneficial because it decreases costs associated with voice and data service. In addition, the service sent through digital signal comes with a greater quality and more speed than is available from the traditional signal.
