Questions and Answers About DSL
We offer a unique service handling CenturyLink (Qwest) to get the best promotions and the best plan for you while you never have to talk to either their Business Office or Technical Support. Our techs here in Denver will troubleshoot with you and make any calls needed to CenturyLink.
1. What is DSL?
DSL stands for Digital Subscriber Line, a technology that brings high bandwidth (fast connections) to homes and businesses over your existing telephone line. Because DSL is much faster than a regular dialup Internet connection, it's ideal for watching online videos, videoconferencing, downloading pictures and software, listening to MP3 music, uploading Web pages, and more.
Because DSL uses your existing telephone line, it does not require you to install an additional phone line. This also allows you 24-hour access to the Web without tying up your phone line with a busy signal. It's also possible to have a DSL connection without phone service.
2. What are the benefits of E.Central's DSL service?

5. Do I need a new modem?
Depending on the DSL service CenturyLink provides in your area, you may or may not need a new modem. E.Central Tech Support staff will help you determine what is required by CenturyLink.
6. What are the minimum PC requirements for using DSL services?
Both Windows PC and Apple Macintosh computers will work with DSL. An ethernet connection is necessary to set up the CenturyLink modem. E.Central Techs can help you find out if your computer will work with DSL.
7. Do I pay for service on a per minute basis?
No. One of the advantages of using DSL is there are no per minute usage charges. This is a flat rate service with a fixed monthly fee. Use your DSL as often as you like. Since it is always on, you get even more useage from the Internet.
8. Can I use my phone and fax machine on the same line as the DSL?
Yes, the voice line supported by DSL service is just like any other POTS (Plain Old Telephone Service) line. Simple plug-in filters provided with the CenturyLink modem must be used on each phone to keep from disrupting the DSL service.
9. What needs to be done to my computer to use DSL services?
Most computers are already set up for high-speed access. E.Central's tech staff can walk you through connecting the CenturyLink modem.
10. Is my high-speed DSL connection secure?
From a security perspective, DSL (and cable modem) networks are not very different from analog modem-based dialup networks. They connect users to email and the Internet using IP as their network protocol. However, DSL and cable modems are more attractive than dialup connections to hackers for the same reasons that make them more attractive to users. The ease of connection and available bandwidth of these networks result in users often staying online much longer, making them more vulnerable to attack attempts.
Fortunately, there are precautions you can take to improve the security of your DSL. The following are general recommendations you can take to help improve security:
Use of intrusion detection systems and firewalls can detect intrusion attempts and network misuse in real time and instantly respond to unauthorized or suspicious activity automatically by logging, recording, or terminating actions. Intrusion detection systems are only designed to detect known attacks; they can be breached by newer types of attacks that are not in the predefined database. Constant updates are required to keep up with current alerts and patches.
- Disable file and printer sharing in Windows 95/98/NT. If you want to share files/printers, password protect these resources.
- Install and regularly update operating system upgrade patches and anti-virus software.
- Do not install and run remote access software such as FTP servers, Telnet servers and PC Anywhere unless you are knowledgeable in the use of data encryption.
- Check out security sites to evaluate the vulnerability of your system.
- Exercise care when downloading and running any attachments sent by email. Make sure it is from a trusted source and that it is scanned by your anti-virus software.
Personal Firewall Software/Hardware
Firewalls allow users to control and filter network traffic coming into or out of their PCs by stipulating certain rules and filtering packets for connections such as TCP/IP, HTTP and SMTP. The better firewall products also include intrusion detection and logging to capture break-in attempts by malicious users. Firewalls come in the form of software, hardware, or a combination of both. Software firewalls only protect the computer they are installed on, while hardware firewalls provide greater protection for multiple computers on a local area network. Consumer firewall products typically range from $29 to $250 for Windows 95/98/NT.
Users who wish to have more privacy can encrypt files, folders, or confidential information on their computer hard disk, as well as any data they send over the network. Sending and receiving encrypted email prevents data sniffers or man-in-middle attacks. Encryption is also used in virtual private networks (VPNs) for end to end secure communication. Encryption software is widely available at low or no cost.
Virus Detection Software
Firewalls can protect against certain types of attacks, but they typically cannot detect viruses that are sent as attachments to files. There are many virus detection programs available which can monitor all files, inputs and outputs, downloads, program executions, email communications, and other system-related activities. When a virus is detected, the program usually notifies the user and gives his the option to clean or delete the infected file before further damage can occur.
