Internet Modems

DSL modems or ADSL modems are devices that are used to connect computers or routers to DSL phone lines. This allows users to experience an ADSL service that is typically much faster than a dial-up service, the first internet service that was available. Some DSL modems manage the connection and the sharing of the ADSL services with a group of machines such as DSL routers or residential gateways. DSL routers have functional blocks that perform framing. Typically, a DSL modem will work as a bridge and will not need an IP address, although it may have one assigned for managing purposes.

DSL modems modulate high frequency tones for the broadcast to DSLAMs and receive and then demodulate them from the DSLAM. They serve basically the exact same function as the voice band or dialup modem, with a few differences. DSL modems are typically external or outside the computer and are wired to an Ethernet port or USB port. Voiceband modems are typically built inside computers. Voiceband or dialup modems use the same frequency spectrum as traditional telephones and will typically interfere with the voice service of your telephone. If your computer is on a dialup modem then you will be unable to make a telephone call from that same phone line while using your computer. DSL modems use frequencies that range from 25 kHz to more than 1MHz. This allows them to not interfere with the voice service on your telephone, which is normally in range from zero to 4 kHz. While your computer is using a DSL modem, your telephone line is left intact. You can talk on the telephone while using your computer, even though they may run from the same telephone service.

DSL modems also may vary in data speed from hundreds of kilobits each second to several megabits per second. Dialup modems are typically 56K modems and are usually limited to around 50 kilobits per second. This is why you may hear people talk about how much faster their internet pages load when using a DSL modem as opposed to a voice band or dialup modem.

This connects them to the internet. Most dialup modems can be dialed into the internet directly from anywhere in the world.

Most of the technical qualities of DSL modems are lost on the average consumer. The main attraction of DSL modems for consumers is their greater speed of connection and the ability to use the telephone and the computer at the same time. The faster the modem the better as it makes searching the internet for products such as coffee (Verdecoffee – England) faster.
