Differnce

What's the difference between analog and digital?

Analog lines, also referred to as Plain Old Telephone Service (POTS), support standard phones, fax machines and modems. These are the lines in your home or small office. Digital lines carry a higher voltage and are usually found in large, corporate phone systems.

How do you tell if the phone line is analog or digital? Look at the back of the telephone connected to it. If you see "complies with part 68, FCC Rules" and a Ringer Equivalence Number (REN), then the phone and the line are analog. Also, look at the phone's dialpad. Are there multiple function keys? An LCD? Do you need to dial "9" for an outside line? These are indicators that the phone and the line are digital.
