DSL Modems

DSL modems are devices that connect to telephone wiring yet do not require dial-up service to get access to the internet. The modems work with existing routers or come with dedicated routers to provide wireless access for network computers, so all computers in the home or in an office require just one telephone hookup. The DSL modem is the competitive alternative to cable internet access. Staples® has a range DSL modems as well as other computer accessories.

DSL Modems Offer Several Advantages to the Alternative
Theoretical internet connection rates, measured in megabits per second, might favor cable access on paper, yet the connection speeds of DSL and cable are perceptively about the same. The advantage of DSL is that it is normally less expensive than cable, depending on how far the DSL modem is located from a central telephone office. Another advantage is that telephone wiring is available just about anywhere. Perhaps the most desirable feature of DSL over cable, particularly for businesses, is that a DSL line is dedicated to the user environment. It isn’t shared among hundreds of users in your neighborhood or area, so it will maintain its speed and not suffer any buffering problems like cable internet. You can also talk on the phone and access the internet at the same time, because the voice and data-reception signals over telephone wiring run on different frequencies.

The Technology of DSL Modems Is Sophisticated and Adaptable
DSL internet access comes from most major telephone carriers, including Verizon®, AT&T®, and Century Link®. One drawback with DSL technology is that the carrier must have an operating center located nearby. Another is that DSL telephone reception is much faster that DSL telephone sending, so emailing and uploading functionality is slower.

Technical engineers have overcome these two constraints by developing several different signal protocols to extend the reach of telephone frequency signals and to equalize reception and sending signals. The best DSL modems offer a choice among these protocols, including very-high bit-rate DSL (VDSL), symmetrical DSL (SDSL), rate-adaptive DSL (RADSL), ISDN DSL (IDSL), and universal DSL (Uni-DSL). Customers choosing a DSL modem for internet access should determine what protocol is best for their purposes and whether the modem is adaptable to it.

How Do DSL Modems Connect to Computer Systems?
A modem connects to a computer through the USB port or the computer’s ethernet WAN port. Internet access for networked computers may be through network routers or switches, but many models combine the modem with the router, and offer signal amplifiers, external antennas, and beam-forming technology, or modem-signal focusing, to improve range and reliability. Other modems offer multi-USB ports that provide additional storage and transfer options and greatly speed up streaming times, ideal for gaming activities. They also offer features like secure remote access to your home computer from unsecured Wi-Fi® hotspots.

What Types of Security Arrangements Do DSL Modems Offer?
The dedicated signal to the modem automatically provides a securer connection during internet use. Most modems relying on DSL technology also offer an extended array of security features that are ideal for office workgroups, small businesses, and home networks, including firewall protection, packet filtering, intrusion detection, and denial-of-service technology. They offer major security protocols as well, including IPSec data authentication, L2TP private networking, NAT remapping, and CHAP identity verification.

Do DSL Modems Fit Conveniently on the Desktop?
The modems, even those combined with a router, are unobtrusive, normally no wider or deeper than 5 inches, with sleek height profiles.
