Analog modem connection is different from cable modem or DSL modem

Hi Ms. Melina Foster

Almost all calls in US are converted from analog to digital at your local phone company office, and stay digital until they reach the local loop of the place you call. So what is going on is we start with digital data at our computer, convert it to analog in our modem, and send it out to the phone system. The phone company switches it back to digital and transmits it, then converts it back to analog for the local loop at the other end.

 

There, the modem converts it from analog back to digital for the remote computer. A DSL line runs through the same line as your phone. The line used to carry ADSL and phone service is a fiber cable. The lines in your house are copper though, and are therefore not digital. An ASDL modem still has to convert an analog signal to digital. Otherwise, it wouldn't be a modem. The purpose of modem is to convert digital signal into analog and sent through telephone cable which is usually analog in the conventional telephone.

 

Hope this help,

The word modem is derived from 2 words, modulator and demodulator. These words were picked since they describe the actions a modem takes in the most precise way. Modems are no more than an extension to a computer, designed to use ordinary telephone lines to carry digital computer data. It is used to connect to the internet with the Internet Service Provider and can also be used to send fax transmissions.

There are 2 ways to install a modem on your computer. You can either have it as an internal modem or an external modem. Once it is connected, the device will send data back and forward between your Internet Service Provider and your computer. There are different types of modems and they are:

• Analog — used for dial-up connections;
• Digital Subscriber Line [DSL] — high-speed broadband connection;
• Cable — high-speed broadband connection;
• Integrated Services Digital Network [ISDN] — transfers information in 64 kilobits per second [Kbps] channels which can be combined for higher speed.
