Module 9: Digital Communication

Rest assured that the analog modem has not died out. It has been reduced to the size of a flash drive and is attached to a USB port. In spite of the advancement in circuitry development, it requires an analog phone signal to work and maintains all the previous restrictions. Several industries generally require analog communications for electronic billing. Here is a typical statement still found for electronic billing:

Steps to Setup Communications Software

IMPORTANT: Your computer must have a dial-up modem in order to connect to the telecommunications server. If you have telephone service through Digital Subscriber Line (DSL) Internet, cable Internet, or any other Voice-over Internet
Protocol (VoIP) connection, such as Vonage, you will not be able to connect properly to the telecommunications server. You must have a traditional phone line with a dial-up modem in order to securely and successfully connect.

Digital communications, in comparison, have continually evolved in design and delivery methods. Verizon with its fiOS service has opted to run fiber optic cable to everyone’s house or business. This allows blazing fast speed that is currently unattainable with copper wire. AT&T U-verse has taken the approach that runs fiber optics to the neighborhood and then copper wire to the home or business. Analog or digital - there are still choices to be made in selecting the most appropriate services.
